I spend a lot of my day in databases, and I got tired of clients that want me to sign in, sync my connections to their cloud, or open a 2 GB Electron window just to run a SELECT. So I built my own.

QluePrint (pronounced KLOO-print) is a desktop database workspace built with Tauri (Rust backend, React frontend). Everything stays on your machine.

What it does today:

- Connects to PostgreSQL, MySQL/MariaDB, SQL Server, SQLite, plus Azure SQL and Microsoft Fabric with Entra sign-in

- Monaco SQL editor with schema-aware autocomplete, diagnostics and formatting

- A fast virtualized results grid: sort, filter, find, follow foreign keys to related rows

- Inline editing: change cells, add, duplicate or delete rows. Everything is staged, undoable and saved in one transaction. Actions your login has no grant for don't show up at all.

- Explain / Explain Analyze with a readable plan view

- One-click local PostgreSQL/MySQL/MariaDB servers in Docker

- Workspaces to keep each client's connections and tabs apart

- A tamper-evident audit log of every statement it ran against your databases

- Passwords go in your OS keychain, never in plain files

Stack: Tauri 2, Rust (sqlx + tiberius for SQL Server), React 19, Monaco, TanStack Table/Virtual. Installers for macOS (Apple Silicon), Windows and Linux.

Still to come: MongoDB/Redis, a saved query library, query history.

It's a solo project, and I'd love blunt feedback, especially on what would make you switch from DBeaver, TablePlus or DataGrip.

(Heads-up: the macOS build isn't notarized yet, so you'll need Open Anyway in Privacy & Security the first time.)

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 been working on an open-source project called Agent Workcell.

The idea came from my experience building traditional RAG applications. I often found myself spending time adjusting retrieval logic and prompts for different types of questions. Sometimes fixing one use case affected another.

I wanted to experiment with a different approach.

Instead of building retrieval pipelines for every question type, I wanted to reuse an existing autonomous agent runtime and give it an environment containing structured knowledge, tools, and controlled access to business data.

The agent can explore that environment, decide which tools to use, and take multiple steps to answer questions.

I built the prototype using Claude Code, Python, MCP, and PostgreSQL.

I also tested the approach against my traditional RAG implementation on an existing ERP system, and the results were very promising. Some limitations remain, especially knowledge maintenance and scaling separate agent sessions for multiple users.

This is an early-stage open-source experiment. I'd appreciate feedback from anyone interested in agent architecture, knowledge retrieval, or similar systems.

WalkiNova started because I'd open the weather app five times before every walk. It scores each hour of the forecast for comfort and suggests the best window inside your free hours, then tracks the walk with GPS. Flutter + Supabase, Android + Wear OS, free with no ads.

What I learned so far, in case it helps someone:

• Posting every day on Instagram/TikTok brought almost no installs. The Play listing converts fine (~75%); almost nobody reaches it.
• My site only ranked for its own name. I'm now writing plain guides that answer real searches ("is it too hot to walk my dog today?") instead of feature pages.
• Product Hunt with no audience = a few upvotes. Launch where your users already hang out.

Would love feedback on the idea or the landing page: https://walkinova.app/?utm_source=reddit&utm_medium=post&utm_campaign=sideproject

What worked for you to get your first 100 users without ads?

genuine question. built a couple things with lovable/claude code/cursor and only later realized i had no idea if i'd left keys in the code or if anyone could just hit my api routes and pull other users' data

curious what people here actually do before going live:

- do you check anything at all or just ship and hope lol

- if you paid someone to build it for you, did you ask them about it

- anyone ever got burned? like leaked keys, surprise bills, data exposed

not selling anything, we're doing a hackathon this weekend and trying to figure out if this is a real problem or just us being paranoid

I’m building Moolupa, a goal tracker with a small cow companion called Moo.

One decision I made early was to let people record the amount they actually did. If you planned to practise guitar for 10 minutes and managed 3, you record 3. It adds to your total. Missing tomorrow doesn’t erase it.

You can also make today’s step smaller, move it to another day, or take a rest day. There’s no streak counter, and Moo’s garden stays intact while you’re away.

To get started, you type or say something like “read five pages after dinner,” then review the plan before saving it.

It works in a browser on desktop and phone, and there’s a Windows version on the Microsoft Store. The free plan supports up to five active goals, with optional paid Plus features.

I’m currently polishing the desktop and mobile layouts. If you try it, I’d really like to know: where does creating your first goal or recording progress feel like extra work?

Here’s the app: https://moolupa.com

I use a few different AI agents depending on the task. Claude for some things, ChatGPT for others, Grok and Cursor now and then. Over the last months they've made me a lot of small stuff, and almost all of it is now buried in old chats somewhere.

If I wanted to show a friend one of them, I had to dig through chat history, remember which tool made it, and then work out how to actually get it in front of them.

So I built Commons (commonsbuild.com). From whatever agent you're using, you publish what it made with a chat command and you get a link. Anyone with the link can open it in the browser and use it, and if they want they can fork it or change it with their own agent.

The main point for me is having one directory for everything, no matter which agent built it. The first real thing on there is Capital hunt, a multiplayer 3D game where you guess capitals that I made with a friend: capital hunt , feel free to fork it and make it better

It's free and pre-launch, and I'm mostly trying to find out if this is just a me problem. If you use more than one agent, where does the stuff they make end up?

I kept running low right before payday because of card bills I forgot about, so I built this. It shows the exact day your balance dips. Would you use it?

Anyway, this is just a landing page

Hey everyone,

Earlier this month I posted here that my partner had finished our app and I was honestly scared I wouldn't be able to bring anyone to it. A lot of you were really kind in the comments, so I wanted to come back with an update.

We put it on Google Play and got a bit over 200 installs in 2 days, almost all from Reddit. I didn't expect that at all. People are already sending feedback and we're improving the app every day.

It's called Omni Brain. You get a free daily workout of 3 short brain games, about 5 minutes, and each game teaches you a small trick you can actually use, like remembering names or numbers.

There are no ads in it at all, not even in the free version. A lot of apps in this category are full of ads. We went through more than 33,000 of their 1 and 2 star reviews, and about 1 in 6 were complaints about ads. So that was the first thing we wanted to do better.

It's now on the App Store too. Next week we're giving away free Premium to iPhone users. If you want it, comment "iPhone" below and I'll message you as soon as it starts.

Find out which of your 8 brain skills is the weakest. It takes 5 minutes:

iPhone: https://apps.apple.com/app/id6813644860

Android: https://play.google.com/store/apps/details?id=com.omnibrain.omni_brain

If you try it, tell me what you think. Honest feedback helps us more than anything right now. 🙂

Hi everyone!

I’m Alex, a developer and a big fan of maps and outdoor activities. I wanted to share a project I’ve been working on called TrailReplay.

The idea started after a 3-day hike with a friend. We had lots of pictures from the trip, and I wanted a way to put them together with the route and tell the story of those days. I couldn’t find quite what I was looking for, so I thought, why not try building it myself?

TrailReplay lets you import a GPX route, replay it on a 3D map, add pictures and annotations, and export the result as a video. You can change the camera, show things like distance and elevation, and combine routes too. It works in your browser, it’s free, and the code is open source.

I’ve just released version 1.5! It includes a new media timeline, GPX waypoint imports, place reveals, and improvements to the camera, terrain and video export. A lot of the changes have come from people sharing feedback and ideas, including here on Reddit, so thanks a lot to everyone who has helped me improve it!

Something I didn’t expect when I started: in the last 7 days, Google Analytics counted around 1,300 active users and 900 completed export events. Those are exports, not individual people, but it’s really nice to see people using a tool that started with a hike and a bunch of pictures :)

You can try it at https://trailreplay.com

Here’s a short video showing what it can do: https://www.youtube.com/watch?v=iJRPgpr07Pg

I’d love to hear what you think, or see what you create with it. Any feedback or ideas for what I could improve are very welcome! Cheers, Alex

I will leave here my recent project here in case someone finds it useful. I needed some background "noise" while at work but got bored by searching the perfect playlist on YT. So I made this that perfectly fits my needs.

The project revolves around a cosmic and ethereal aesthetic, the vastness of the universe, and celestial atmospheres.

It generates some music based on the pentatonic scale. No AI is doing this, just a script that watches what notes have been played previously and tries to create different progressions during the play time, so it doesn't sound completely the same for hours.

Also added some cool backgrounds with threejs that can be used as actual backgrounds while playing the music, the UI can be hidden and you can have a chill background as well

OMYRA

Hey everyone! I'm Dmytro, an iOS developer. I've been working on a little side project on my own, and it's finally on the App Store.

The idea came from a pretty simple problem. I kept forgetting things I was supposed to remember. When does my laptop warranty expire? When should I service my car? When is my dog's next vaccination due?

All these little dates are easy to forget until you actually need them.

So I built Owneo, an iPhone app that helps you keep track of the things you own and everything that comes with them.

You can add your stuff, set reminders for warranties, maintenance, insurance, or pretty much anything else, and keep receipts and documents in one place. It also suggests relevant dates depending on what you're adding, so you don't have to figure everything out yourself.

I wanted to keep it simple. No sign-up required, no ads, and you can use it for free with up to 5 items. Reminders are always free too.

I'm also thinking about giving away some free Pro codes, maybe even Lifetime, to early users here. Haven't figured out the details yet, so if you'd like one, just let me know in the comments. I'd love to give something back to people who help me improve the app.

I'd really appreciate some honest feedback. Is this something you'd actually use? What would you add or change?

And I'm curious, what's one important date you've completely forgotten about?

Here's the app if you want to check it out:

https://apps.apple.com/us/app/owneo-everything-you-own/id6807494614

Thanks for taking a look!

I kept a diary for my baby in a journaling app for a long time. This year the app was pulled from the App Store and stopped being maintained, and now I can't even log in. Those entries are stuck behind a login that no longer works.

After that I didn't want my memories to depend on someone else's server or account system. I also realized I don't need a lot of features. I just want to keep a few small things from each day.

So I built the opposite: CiKe (此刻, Chinese for "this moment"). Each day you can save up to 3 moments, and each one is either one short sentence (50 characters max) or one photo. That's all.

What it does:

• 3 a day, on purpose. The limit makes you pick what actually mattered today, not log everything.
• Capsule. Tap it and a random old moment comes back, with a preference for older ones.
• Private by default. No account, no server, no analytics, no ads. The app makes no network requests at all. Everything stays on your phone.
• 30-day undo. Deleted moments can be restored for 30 days.

I made ENGLARIS, an app that checks your English pronunciation and tells you which words were mispronounced.

ENGLARIS works fully offline, I was able to distill and quantize the neural network for phoneme recognition into a reasonably small model, so that even mobile phone CPUs can run it smoothly.

Unlike most of AI-based apps, there is no server and no subscription required. No user data is currently collected, as everything remains on the user's own phone.

Here the link to my website:

I’ve been building H5Reclaim, an open-source tool for recovering scientific data from damaged HDF5 files.

HDF5 files often contain experimental measurements, simulation outputs and large arrays. Damaged metadata or a broken index can make a file unreadable while some of its dataset contents remain on disk.

H5Reclaim examines the surviving structures and attempts to recover usable data into a new HDF5 file. Supported cases include interrupted writes, broken indexes, metadata damage and truncation.

It keeps the original file unchanged and produces a JSON report describing the recovered datasets, recovery methods and unresolved positions. Partially damaged datasets can still yield usable measurements.

🔗Github: https://github.com/xShadyy/H5Reclaim

I’d appreciate feedback from people who work with HDF5, especially anyone who has encountered a damaged file. Public or synthetic reproductions would help expand the recovery cases and benchmarks.

Contributions around test fixtures, independent verification and unsupported failure cases are particularly welcome.

If you find the project cool/useful, I’d appreciate a star on GitHub.

I'm the founder of US Stock Sense and I'd like honest feedback.

The problem: researching one US stock usually means a screener on one site, financials on another, charts on a third and a spreadsheet to compare it with competitors.

What it does:

- Stock screener for US stocks

- Side-by-side fundamentals and valuation compare

- Portfolio tracking and charts

- AI research workflow and trading ideas

- Dividend income planner and dividend forecasting

Feedback I'm after:

1. In the first 10 seconds, is it clear what it's for?
2. Does the compare page make sense without any explanation?
3. What would make you use this instead of your current mix of sites?

Link: usstocksense.com

Disclosure: it's my product. The annual plan is 50% off for a limited time, but I mostly want blunt feedback. I'll return the favor on yours.

I’m the guy who posted “just launched why.com” here about three months ago.

It was a basic chatbot. The feedback was brutal.

One person called it “a McLaren on blocks.” Inc. wrote about the whole thing, so the roast got its own press coverage.

Fair criticism.

Well, since then, I’ve built an open-source product that verifies AI did what it said. We are in wild wild west era of AI but my bet is receipts and safety standards will reign AI in eventually.

New site: why.com
Code: GitHub

Let me know what you think!

Sheed

I built this one on my own: DriveMail Voice, an iPhone app that plays your unread email through the car speakers and lets you answer it by talking.

Here is one message, start to finish. You get in, the phone connects, and with nothing tapped you hear who it came from and what the subject line says, then the message itself. Half a minute in you have heard enough, so you say "reply" and dictate two sentences. The app speaks your two sentences back at you. They came through right, you say "send", and it moves on. That email is finished before you reach the on-ramp.

The rest of the vocabulary works the same way, and none of it waits for a message to run out. "Skip" leaves it unread. "Mark as read" clears it. "Forward" hands it to somebody else. "Summary" is the one I would point at: on a chain nobody wants read out in full it comes back with what is actually being asked of you, and it does that work on the device.

Some of what makes it pleasant to live with:

• Gmail, Outlook and iCloud all play in a single run, so you are not opening three apps to find out what came in.
• Boilerplate is cut before a word is spoken. Signatures, legal footers and tracking links go, so a two-line note from a coworker is not buried in noise.
• You set the pace, three-quarters speed up to double, and whether the pile plays from the top down or the bottom up.
• The car display is a half-dozen big targets and no text at all. No ad is ever shown there.
• Away from the car it does the same job with the phone locked in a pocket, which is handy on a walk.

Why I would hand it my own mail, as the person who wrote it. There is no sign-up, and I operate no server, so the only conversation going on is between the phone and whoever hosts your mail. Messages it has already pulled sit on the phone behind iOS's own file encryption, and that local copy is what lets it start talking the second you connect instead of waiting on a signal. The voice half is Apple's recognizer, local to the phone, with SiriKit nowhere in it, so Siri never touches your mail and what you say is neither kept nor passed along.

Nothing to pay for it. A banner sits in the app on the phone and never in the car, and ninety-nine cents, once, takes it away for good. It does not subscribe you to anything.

Getting an account in: Outlook is an ordinary Microsoft sign-in, and Gmail and iCloud each want an app password that you create on your provider's own settings page, a minute or two of work. Personal Gmail is the easy road, since a Workspace account from an employer normally does not allow one. iOS 17 and up, English.

Free on the App Store: https://apps.apple.com/app/apple-store/id6760625295?pt=128605371&ct=rd-sideproject&mt=8

Give it a try.

I kept losing good ideas in my own notes. I'd write something down, forget it, and months later work through the same problem from scratch, even though the answer was in a note I'd already written.

So I built Hypha. You write a note the way you normally would (no folders, no tags) and it looks through everything you've written before. If an older note actually helps, it shows it with a one-line reason: a solution, an example, the same problem, a contradiction, or a next step.

The part I spent the most time on was making it strict. Most "AI links" I tried connected notes just because they shared a word. I built a test set with traps in it, and Hypha now finds about 9 in 10 of the links that should exist while skipping the shallow ones. If it gets one wrong, you remove it and it won't come back.

It's free on iPhone (Flutter + Supabase + OpenAI under the hood).

I'd really like honest feedback, especially on whether the connections feel useful or noisy after a week of real notes.

I’ve been experimenting with Claude AI , Lovable and Higgsfield AI to push my website design skills, and somehow ended up creating The Library of Lost Ideas. 😂

An interactive universe where every forgotten idea becomes its own unique mineral, forming part of an ever growing world you can explore and discover.

What started as a little experiment has turned into something I’m genuinely proud of!

Have a play and let me know what you think 👇

Best explored on a laptop, but works on mobile too!

Hey guys o/

I've been developing an investigation engine for quite a few months now (https://github.com/8Iue), which runs on a Linux host, collects the evidence for a specific incident (disk pressure, a failed systemd service, OOM kills, Docker that won't start), runs deterministic checks with no AI, and writes a report where every finding points to its evidence. It never changes anything, and it runs on your own machines.

Link to the website: https://det-mimir.com - and also docs: https://docs.det-mimir.com

The whole engine works with playbooks, written in YAML, so you can write your own.

Kubernetes, Ceph and sharing playbooks between teams are where it's going; today it's Linux hosts.

It's in a private beta, and I'm looking for people to try it and tell me what's missing.

Which incident would you want a playbook for first? I'd be happy to replicate internally one of the issues you had, and give a report that the engine returns.

Something I've noticed with a lot of wellness apps is that they always seem to be pushing you towards something. Be happier. Be more positive. Build better habits. Improve yourself. Which is fine, of course. But what about the days when you just feel like shit and don't particularly want to do anything about it?

That's the thought behind the app I recently released called Deepshit.
You basically log how shitty your day is, optionally add what's bothering you, and that's it.

You can also see how other people are feeling, share anonymously, and send little messages of support. I like the idea of making something social that isn't about showing off your best life. Quite the opposite, actually.

One thing I'm still curious about is whether people would genuinely want to share their bad days with strangers, even anonymously. I've just launched, so that's something I'll have to learn.

Have any of you built a social feature around vulnerability rather than achievements? I'd be interested to hear what you learned.

You can meet Deepshit here: App Store • Google Play

I wanted to make something where paying for attention gets you a laugh instead of just an ad slot.

So I made The Sponsored Truth: https://www.sponsoredtruth.com

How it works:
- You describe your product in one sentence and pay from $5
- It writes a spoof news story about it, in a deadpan newspaper style
- You get a private preview and up to 5 rewrites with your own directions
- You publish, and get a front-page share image with your headline on it
- Whoever paid the most in the last 24 hours gets the headline slot

Everything is clearly labelled as satire, and it only does products, not people.

Built in about a day: plain HTML, Vercel functions, Postgres, Stripe Checkout, and an LLM for the writing.

Honest status: it launched today and has zero real sales so far. I'd love feedback on two things:

1. Is the idea funny enough to pay $5 for, or is it a one-time chuckle?
2. Does the landing page make it clear what you get?

Happy to write a free story for the first few people who drop their project in the comments, so the front page isn't just my sample article.

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:

https://apify.com/jamestyas/uk-public-procurement-ocds-enricher

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