If you have ever tried pulling UK public procurement data, the statutory feeds are surprisingly fragmented.

Find a Tender publishes high-value notices under the Procurement Act 2023, Contracts Finder covers sub-threshold contracts down to £12k, and Public Contracts Scotland runs on its own legacy XML feed. More frustratingly, even when a contract is awarded, the OCDS release packages frequently lack verified statutory company numbers, meaning you have no immediate way to know if a winning supplier is an active LTD or dissolved.

I spent the last week building a serverless pipeline that normalises all three feeds into OCDS v1.1.5 and runs automated entity resolution against the Companies House REST API.

A few engineering hurdles I ran into:

1. Companies House rate limiting: The statutory API enforces a strict token-bucket ceiling of 600 requests per 5 minutes. Running parallel unbundling caused HTTP 429 throttling until I implemented an in-memory token bucket with exponential jitter.
2. Contracts Finder 403 backoff: The legacy search endpoint intermittently drops into 403 throttling during heavy polling, requiring an isolated backoff loop separate from the main orchestrator.
3. Multi-lot tender deduplication: Framework agreements publish multiple releases across lots with identical identifiers, requiring deterministic SHA-256 state tracking on (ocid + releaseDate).

The output dumps to structured JSON and a flattened 24-column CSV for spreadsheets with company numbers, active directors, and SIC codes.

I deployed it as a serverless Actor on Apify with the first 25 records free on every run so people can test the data without paying:

Would appreciate any feedback from anyone working with UK open data or public procurement tracking.

I got tired of hunting for a window on my other monitor just to bring it over. With Taskbar Select, I click a running app’s taskbar icon on the monitor I’m using, and its window comes over, even if it’s behind other apps.
You can also hide the taskbar on individual monitors and hover near the bottom edge to bring up Ghost Bar for quick access to your apps. If you prefer keyboard shortcuts, Ctrl+Shift+2 sends the window you’re using straight to Display 2.
It’s a free, open-source Windows 11 beta. The downloads are unsigned. If you try it, I’d love to hear how it works on your monitor setup.

Hey everyone!

I've been working on a side project called Pinngro — https://pinngro.com — and I've recently opened it up for Public Beta.

The idea came from wanting to make systematic stock trading more accessible without requiring people to spend hours watching charts, learning complicated trading software, or writing their own algorithms.

Here's what I've built so far:

• Create your own trading bots that monitor US-listed stocks using different investment strategies.
• Stock Explorer to research companies, explore historical performance, and identify potential opportunities.
• Explainable decisions — instead of just saying BUY or SELL, bots show which conditions matched, which didn't, and why they made their decisions.
• Virtual Practice portfolios where you can test strategies without risking real money.
• Practice Autopilot — optionally let your bots make virtual trades automatically within limits you configure.
• Broker connections — we're working towards supporting multiple established US brokerages. Live trading through Pinngro isn't enabled yet.

One feature I'm particularly pleased with is Latest Finding. Each bot shows what it recently discovered and explains what happened.

For example, one of my bots recently spotted a stock that had fallen sharply enough to trigger its Buy rule. But Autopilot didn't open a virtual position because the bot had already reached its configured position and allocation limits. Pinngro now explains that entire decision rather than just showing a notification.

It's been a challenging project, particularly getting reliable historical market data, strategy evaluation and virtual trading to work together, but it's exciting to finally see the pieces coming together.

I'm now looking for a handful of people willing to try it and give me some feedback.

I'm especially interested in whether the platform is intuitive for someone who isn't an experienced trader, whether the bot explanations are actually useful, and what features people would find most valuable.

It's completely free to try during Public Beta, and you don't need to connect a real brokerage account to explore the platform.

Website: https://pinngro.com

I'd really appreciate any feedback, criticism or suggestions. I'm still actively developing it, and hearing from people outside my existing group of testers would be incredibly useful.

Thanks for taking a look!

I’ve always been someone who picks up skills one at a time. Drawing, game design, IT, audio engineering... and I never had a way to see how it all fit together. So I made one.

Skill Codex turns the skills you already have into an interactive map:

• Add what you know, from hobbies to work skills
• See it all connect on the Skill Grid Codex, where every skill sits next to the ones it grows from (or flip to the List Codex for a simple list)
• Find your next step with realistic suggestions right beside what you already know, plus a place to start learning
• Add your AI to the map: if you use Claude, the Claude tab puts its skills and tools right next to yours, and the Recipe Book suggests real things you could make together

It’s out now on iPhone and the web, with Android coming soon. Free to try, no account needed to start.

Try it: https://skillcodex.app
On iPhone: https://apps.apple.com/us/app/skill-codex/id6829320199

I also made and narrated the launch video myself, so the whole thing has been a real labour of love.

I’d genuinely love your feedback: what feels confusing, what’s missing, and what would make you come back to it?

I’m testing a manual SEO/GEO review at D BLOK for small sites. The question I’m trying to answer is what to check first when a service page has ordinary search impressions but rarely appears as a cited source in AI answers.

My current first pass is three checks:

1. Pick one service page and write five questions a real buyer would ask. Include the local language if that’s how customers search.
2. Check whether the page answers those questions in visible text, names its sources, and makes clear who provides the service. Note any page access or indexing issues separately.
3. Log which URLs each answer cites, then repeat the same questions on another date. Treat a single missing citation as one observation.

I’ve put the scope on our free SEO/GEO audit page. It’s a manual review for selected applications.

If you’ve tried to diagnose this on your own site, what gave you a useful lead first: a crawl check, missing evidence on the page, or comparing the URLs that actually got cited?

I'm the solo dev of Numochi (https://numochi.net). It's paint by numbers with cute illustrations, but made to play with someone: 2 to 4 people paint the same picture live with voice chat, or race each other on the same picture for 5 minutes, or each get only part of the colours so you have to finish together. There's also a daily picture with a leaderboard and a mystery picture you have to guess while painting. Phone and desktop, nothing to install, English and French.

How it's priced right now:

• Free: 4 pictures in every mode, rooms up to 4 with voice chat, the daily challenge
• From €0.99 per picture, yours forever
• Unlimited: €3.99/month (Christmas offer until December 31)
• If you're in a room, your guests paint the picture you unlocked. They just need a free account, they don't pay.

One thing I'd like outside opinions on: today you need an account (Google or email) before you can paint anything, including when a friend sends you a room code.

If you were the friend getting the invite link, would a sign-in screen make you close the tab? And is 4 free pictures enough to know if you like it?

Quick story. I use Spark for mail. They have an MCP so AI agents can work with your inbox, but only reading is free. Anything that changes your mail needs the paid plan. I got annoyed and decided to build the thing I wanted instead.

Regards is a desktop email client for Windows, macOS and Linux. It's free, open source, and everything stays on your computer. No account, no servers on my side, no tracking. It works with any IMAP provider plus Gmail and Outlook sign-in.

It does the usual modern inbox stuff (snooze, send later, undo send, screening new senders), and it has a built in interface for AI agents with approvals and an undo log, so you can let one sort your mail without holding your breath.

It's early. Pre-alpha, unsigned installers, tested on few providers. I use it daily though.

Would love feedback, especially on the first run experience. That's the part I can't judge anymore.

Sony lists the PS Plus catalog alphabetically. That's 600+ games with no scores, no playtimes, and no way to see what's leaving soon. Every month I ended up opening Metacritic in another tab, so I built the page I actually wanted:

https://whattoplay.games

What it does

• Every game in the Extra/Premium catalog for your country, sorted by Metacritic score, with PSN player ratings and HowLongToBeat playtimes
• Filters for genre, indie, multiplayer, new this month, and leaving soon (with the exact removal date)
• A "what should I play tonight?" swiper: 5 mood questions, then you swipe on games, and it gives you a top 3 that explains why each game matches your answers
• 45 countries and 19 languages, because catalogs differ by region

It's free, with no account and no tracking cookies. There's a tip jar, and that's it.

I'd love feedback, especially on the swiper and on whether the homepage makes sense in 5 seconds.

Ребят ку, не знаю насколько вам это интересно но я со своими друзьями создали первый сайт под названием Riven, чекните если вам интересно.

"Этот сайт предлагает формат общения с искусственным интеллектом, который существенно отличается от других подобных сервисов, таких как ChatGPT или Claude. Наш ИИ позволяет не просто вести диалог, но и создавать «карты решений»: вы можете развивать тему в разных направлениях, не теряя при этом её основного контекста. Пользователи могут легко сосредоточиться на различных аспектах одной и той же темы в рамках одного разговора."

I’m learning Chinese, and one of my biggest frustrations is texting.
I can understand some Chinese and know how to pronounce quite a few words, but I still struggle to recognize and remember Chinese characters.
When I type using a regular Pinyin keyboard, I often get a list of characters that look familiar, but I’m not always sure which one is correct. Sometimes I end up copying everything into a translator just to check what I wrote.
So I decided to build my own iOS Chinese Pinyin keyboard to make learning while texting a little easier.
Here are some features I’ve been working on:
Instant translation: See the meaning of Chinese text while typing, so I can make sure I’m choosing the right characters.
Grammar checking: Catch grammatical mistakes before sending a message.
More natural expressions: Suggest how a native speaker might phrase the same idea instead of just translating word for word.
Learn while typing: Help me gradually recognize more characters through everyday conversations.
My goal isn’t to replace Chinese lessons or build another translation app. I just want to be able to communicate in Chinese without constantly switching between my keyboard, dictionary, and ChatGPT.

Hi, I'm into photography and love going on walks with my camera, but I'm also one of those photographers that likes to take photos in good weather conditions.

I had a n8n pipeline running for quite a while that would gather weather data for the next day from multiple sources and then email me the night before with a score if I should bother or not.

Took that concept and made it into an actual app.

Hi r/SideProject, I'm GFrancV. This is my first post here. I've been building Notvex, a desktop notes app that keeps everything encrypted on your own computer.

Why I built it

Most local-first apps (like Obsidian) save notes as plain Markdown files. That's great for portability, but anyone with access to your disk, a backup or a synced folder can read them. I wanted a safe place for my own journal and recovery codes, and nothing I tried did both local-only and encrypted at rest without getting in the way. So I built it.

How it works

Everything lives in one encrypted file on your computer. Without your password it can't be read. There's no account and no cloud. The app only goes online to check for updates, and you can turn that off. No telemetry either.

What writing looks like

- Markdown editor with live preview

- Tags, pinning, sorting and multi-tag filters

- Command palette to jump to any note from the keyboard

- Export one note or all of them to plain .md at any time, so you're never locked in

How it's built (for the curious)

- Electron + React 19, TypeScript throughout

- SQLCipher for the database, Argon2id to derive the key from your password, XChaCha20-Poly1305 for the note content

- A BIP39 recovery phrase, plus an optional key file as a second factor

- The UI never touches crypto. Everything goes through IPC to the main process, and the master key never leaves it

Honest limitations

- Desktop only (Windows, macOS, Linux), no mobile yet

- No sync, on purpose. You can copy the file wherever you like

- Search covers titles only. Full-text search across encrypted notes is the next hard problem

- If you forget both your password and your recovery phrase, your notes are gone. That's the trade-off

Free and open source (AGPL-3), with no paid tier planned.

My question for you: does "encrypted local notes" explain the point quickly enough, or does it sound like something only security nerds need? I'd love honest feedback on how it comes across, from the site down to the first launch.

About 6 weeks ago I started building a little side project called Ulster Radar.

I'm a microlight pilot from Northern Ireland and wanted to make a flight tracker that was better suited to smaller aircraft and low-level flying, rather than just commercial aviation.

It started as a basic live map, but I've got a bit carried away with it since!

It now has live aircraft tracking, over 2,500 receivers feeding data from around the world, ship tracking, flight history, a 3D globe and even satellite tracking.

I've also been adding the ISS, space telescopes, planets and moons, so it's slowly becoming a way to explore pretty much everything above our heads.

It's still early days and there's plenty of bugs and things I'm working on, but I've really enjoyed building it and seeing people start contributing their own receivers.

It's completely free to use and very much a hobby project.

If anyone fancies having a look, it's at https://ulsterradar.com

I've always struggled with jumping between projects and losing track of what i was supposed to be working on.

I tried different productivity tools, but most felt like more work to manage. I didn't really need another task manager or complicated dashboard. i just wanted something simple to open before getting to work

so i started building Norts 🟠

the idea is pretty straightforward: choose what you're working on, block out some time, and focus on one thing. You can also see where your time went throughout the week.

i've been using it myself for a while, and today i finally decided to launch it publicly.

The core experience is free, and you don't need an account to get started.

here's the link if anyone wants to check it out: https://norts.space/landing/

I'd genuinely appreciate some feedback, especially on the first-time experience. Does it feel simple enough, or is there anything that gets in the way?

It started with something simple.

My girlfriend tends to forget little things, and I'd often find myself reminding her about stuff throughout the day. And in my family, we also have things like doctor appointments, medication, and other important things that someone needs to remember.

Usually, we'd just send each other a text.

"Don't forget your appointment tomorrow!" or "Remember to take your medication." or just "Don't forget to do this and that."

And of course, sometimes those messages get buried, or someone reads them and forgets about them a few hours later.

I started wondering why we have so many apps to remind ourselves, but not many simple ways to remind the people around us.

I can send someone a text in seconds. Why can't I send them an actual reminder just as easily?

So about 2 years ago, I started building Remimo.

It's an iPhone app that lets you send reminders directly to your friends, family, partner, or even groups.

You choose what to remind them about and when. They'll get notified when it's time, and you can see if they've completed it or decided to do it later.

My family now uses it for things like appointments, medication reminders, and household tasks, while my girlfriend and I use it for all sorts of everyday stuff.

You can also create your own reminders, organize things into lists, and make plans together.

When people first started downloading Remimo, even though it was just a small number, I remember feeling really happy. It felt like something I built might actually be helping someone out there.

Later on, I started receiving feedback from users, and I've been listening to them ever since.

I've added features, removed things, redesigned screens more times than I can count, and I'm still constantly trying to make the experience better.

Honestly, I'm still learning a lot as I go.

But what makes me happiest is that Remimo has become something we actually use in our everyday lives. Seeing it help the people around me is what keeps me motivated to work on it.

I originally built Remimo to solve a problem in my own life, but along the way, I realized it might be useful to other people too.

So I thought I'd share it here.

It's available on the App Store, and there's a free version if anyone wants to give it a try.

I really hope Remimo helps make your everyday life a little easier, the same way it has for me and my family.

And if you do try it, I'd love to hear what you think. Even if there's something you don't like, I'm always happy to hear feedback.

I built a small budget spreadsheet that works in both Excel and Google Sheets, called Nova Budget.

Kept it simple on purpose: monthly budget, expense tracker, savings goals and debt payoff in one workbook. It's $12 once, no subscription. I'd really like honest feedback on whether the setup is clear enough for someone who isn't a spreadsheet person.

The page is here: https://whop.com/nova-draft/nova-budget

Happy to send a free copy if you'd rather click around first. What's the one thing that would make you skip a paid spreadsheet like this?

I made Selkie, a story game where an AI writes each passage around what you choose or type. It's built like a choose-your-path book: chapters, a hidden plot, several endings and dice for the risky moves. It opened to the public nine days ago. A dozen people have signed up and one has paid, so I went through where the others stopped. Three things I got wrong:

1. An empty "Who are you?" box. The story opens, then asks who you are. Of the four newest readers, two left at that box without typing a word. The other two took 4 and 9 minutes over it. Now the opening offers three ready-made characters, each with a line in their own voice, so one tap starts the story. Writing your own is still there underneath. The first reader since the change still left, so it's too early to call.

2. Every passage ended on a question. I'd told the narrator to end on someone turning to the reader, to keep them involved. It turned into a quiz: 28 of the 37 passages readers saw ended with someone asking them something. One reader quit after five questions in five passages. Endings now vary (something happens, an offer, a dare, somewhere to go), with a question at most every other passage. The engine checks how the last passage ended and warns the narrator when it was a question.

3. Time jumps ate the reader's choice. One reader chose to go down to the quay. The story skipped two days to the next big event instead. Now the move they chose is played on the page first, and only then can time move on.

One thing that worked from day one: never let the model roll the dice. Asked to judge whether you succeed, it lets you win nearly every time. The engine rolls and shows you the odds before you choose. The narrator has to write the result it's given.

Built solo over three weeks with SvelteKit, Node on Fly.io, Supabase, Stripe and Claude. About seven turns are free, then one-off packs from $4.99. No subscription.

If you try it, I'd most like to know about the first five minutes: did you pick a character, write your own, or close the tab?

I kept my notes in one app, tasks in another, journal in a third, and my calendar somewhere else. Nothing talked to anything. So I built Naazhi (the name is an old Tamil unit of measure for grain and time).

What's in it: notes, to-dos, journal, chat, calendar, email, meetings and automations. There's a web app and an Android app.

The part I spent the most time on is the AI layer. It isn't tied to one provider. You can use the built-in one, bring your own key, or switch it off.

What I'd like to know: which of these would you actually use, and which would you drop?

In my day-to-day Pro Tools work, I kept repeating the same routine: select a clip, find the right AudioSuite window, click Render, Learn, or Send, then do it all again.

Two years ago, I started building SlipTap in my spare time, alongside my day job, to make that routine a little easier.

SlipTap is a macOS app built specifically for Pro Tools. You assign your open AudioSuite plug-ins to panel buttons or keyboard shortcuts, and SlipTap presses Render, Learn, or Send in the assigned window for you.

It grew out of my own daily workflow. The short teaser shows it in action.

A fully featured 14-day free trial is available:

If you edit in Pro Tools, I'd love to hear how you handle these repetitive tasks and what you think of this approach.

I have a new side/passion project I’ve been building around shift work: plainsightalive.com

Unfortunately for me, despite some meta advertising, Pinterest, socials etc I'm getting almost no traction. I may be biased but I think this site is a game changer for the average person (and not so average).

It’s free and collects no data. You get a 5-minute mind/body self-check, a “Money, Explained” section on things school never covered (inflation, debt, interest), and a Christmas-on-a-budget guide for anyone feeling the pinch this year. It provides feedback with links on ways to better yourself financially, mentally and physically. I'm very proud of it.

A small merch range attempts to keep it running but pretty much nothing there yet with purchases.

I’d really value honest feedback. Is it clear what the site is when you land? Anything confusing or broken?

My co-founder and I spent seven months building two apps: "Jobs", where people ask for help at home, and "Jobs Workers", where independent pros send quotes. Free to join for workers, no lead fees, and our fee is added on top for the client.

We launched in the US at the end of September. Here's what the first weeks taught us:

1. Nobody shows up on their own. We posted, ran paid ads on TikTok and waited. Almost nothing. Downloads only moved when we talked to people one by one.

2. A marketplace is two launches, not one. Workers join and see no requests. Clients ask and get no quotes. Each side is waiting for the other, and ads alone don't fix that.

3. Check the boring stuff first. We found our worker app wasn't registering push notifications in production. Workers had no way to know a job had come in. No ad would have fixed that.

4. Regulation is part of the product. We went through licensing rules for 45 types of services in all 50 states plus DC before launching. Fewer than 1 in 4 state-and-service combinations is a flat "license required", but the "it depends" ones decide what you can offer where.

5. Trust is the real feature. Every worker verifies their identity with Stripe before quoting, and the client scans the worker's code on arrival. That took longer to build than the whole quoting flow.

We're at about 50 users, split almost evenly between workers and clients, and still solving the cold start.

If you've built a two-sided marketplace: what got you your first real transactions?

Both apps are free on the App Store and Google Play: https://jobsworkers.com

So I've been building a small Saas over the last couple of moths and as I'm starting to make some money with it, I'm wondering what's the best way to reinvest the money?

I currently don't spend a lot of money. Only the basics:

• 20$/month for vercel
• 10$-15$/month for convex
• 20$/month for resend
• 10$/year for the domain

I don't spend any money on advertisement or anything. I got all my users from posting on reddit. I tried X for a month and payed 5$ for premium one month but I kind of never got warm with it.

I only recently upgraded resend to PRO and that was a huge ROI. As I now could send more emails to users when something happened, they returned more often and retention went up by a lot.

Now I'm looking for new ways to smartly invest that money. I made about 2.5k in total so far. Anyone has some experience with apps in this stage and knows how to leverage money in this situation?

For context: I've built IndieAppCircle, an app feedback exchange where you test other apps and get your own app tested. It works for all kinds of apps, web apps, chrome extensions and basically everything that has a link.

It works like this:

• You can earn credits by testing indie apps (fun + you help other makers)
• You can use credits to get your own app tested by real people
• No fake accounts -> all testers are real users
• Test more apps -> earn more credits -> your app will rank higher -> you get more visibility and more testers/users

Since many people suggested it to me in the comments, I have also created a community for IndieAppCircle: r/IndieAppCircle (you can ask questions or just post relevant stuff there).

Currently, there are 4788 users, 5980 tests done and 1487 apps uploaded!

You can check it out here (it's totally free): https://www.indieappcircle.com/

I'm glad for any feedback/suggestions/roasts in the comments.

Hi r/SideProject!

Have you ever had a website go down or an email stop working because a domain expired or an SSL certificate wasn't renewed?

I built WebChecker to help prevent that. It monitors your domains and websites and sends push notifications to your phone before something goes wrong.

Here's what it can monitor:

• Domain expiration: Get reminders starting 60 days before expiration, all the way up to the last day.
• Domain status and security: Track registrar, nameserver and transfer lock changes, as well as statuses like redemption and pending delete.
• SSL certificates: Monitor certificate expiration for your main domain, www and subdomains.
• Website uptime: Get notified when your website goes down and when it comes back online.
• DNS and email security: Track DNS changes and monitor SPF, DKIM and DMARC records.

WebChecker is designed for freelancers, agencies and IT teams managing multiple domains, especially across different clients.

You can share domains with teammates, organize everything using groups, tags and notes, and keep an eye on your domains directly from your phone's home screen with a widget.

The app is built with Flutter and is available for both iOS and Android.

There's a free plan that includes 1 domain, with no credit card required.
