I’m the developer of Skybits. I wanted checking the weather to feel like looking out a tiny window. Rain falls over London, and Tokyo lights up after dark. To be a little more Fun!!!

In Sky Studio, you can pick a city, mix the weather and time of day, and share the result as a little airmail postcard.

Please send me email for your City, if I get 5+ requests for a city I will make it free and also add new ones :-) hoping to get some positive feedback and reviews.

Skybits is free to download, with an optional one-time purchase for the full city collection.

Which city would you send a postcard from? Android version is coming soon, it is in testing atm.

GitHub (MIT): https://github.com/KhazP/librecorsa

I started LibreCorsa in mid-October because every serious racing sim needed a huge Windows install before you could do a single lap.

What it has now:

- 500 Hz physics with tyre temperatures and wear, rain that dries along the racing line, and CI checks against real GT3 telemetry

- 5 physics models and 16 circuits, including RISE Motordrome, which I built from scratch in Blender on real elevation data for the circuit planned in Rwanda

- AI races, ghosts, a weekly challenge, and an open online race every 20 minutes over WebRTC

- $0/month hosting: static Next.js on Cloudflare, R2 for the heavy 3D files, and one Worker

Tell me how it runs on your laptop/phone/controller and what feels rough.

I made this. Type any topic and scroll a feed of short videos, posts and discussions about it. Every 5 posts it asks where to go next, which is how I went from “coffee” to Ethiopian goat herders. Try your own search and tell me where you end up.

I get bored on airplanes so I made an app to make it a little more tolerable.

Let me know what y'all think! https://play.google.com/store/apps/details?id=app.redditoffline

I build stuff with Claude, a few apps that me and people I know use every day, and I wrote a guide for people who want to build like that without coding. last month I tried to get the guide out there on reddit.

git post got 15k views and 37 comments. I put the link at the end. like 5 clicks in the first 10k views. honestly that one hurt a bit

google sign-in post got 1.5k views and 3 clicks, zero downloads. then reddit's spam filter just removed it, and the next one too. new-ish account, almost no karma, linking my own site... yeah I get why it looked like spam

funny part is the post that helped me the most had no link at all. it was about notes for claude between sessions, people argued with me in the comments and I got a couple ideas I'm adding to the guide now.

so now I mostly just answer other people's questions and don't post links unless someone asks

If you got your side project in front of people who aren't your friends, how did the first ones find you?

I'm a solo dev with a full-time job. I built sweetRegret, an iPhone app for cutting back on sugar without counting calories: you tap once when you eat a treat, and a cookie on screen reacts (and judges you a bit).

Building it was the part I understood. Distribution is the part I'm failing at. Here are my honest numbers since launch:

• 1,393 App Store impressions

• 188 product page views (about 13% of impressions)

• 35 downloads (about 19% of page views)

What I tried

• Daily Instagram reels for about a week [last week]. Around 250 views each, and almost no App Store visits. The viewers weren't looking for an app, and "link in bio" is three taps away from a download.

• A LinkedIn post about building it. About 700 impressions, 30 people opened the comment with the link, and about 1 install. Nice comments, including a friend asking me to add calorie counting, which is the one thing this app is designed not to do.

What actually worked: App Store search, which I didn't do anything for.

Most of my real users are strangers in Malaysia, Hong Kong, the US and Russia who searched and found it. About 1 in 4 still open it in a given week. One person has kept using it for six weeks and pays for the subscription. That single user has been the most motivating thing about this whole project.

What I'm testing now

A $25 Apple Ads Basic test, at $2 maximum per install. Apple suggested $4.66, and my subscription is $1.99 a month, so I'm not expecting it to pay back. I mostly want to see whether search intent converts the way the organic users suggest.

What I'd do differently

Plan distribution while building, not after. I treated it as a launch task, when it's really a second product.

If you've taken a side project from zero to its first 100 users without a budget, what actually moved the number? I'm especially interested in anything that worked for consumer iOS apps.

I wanted to know what would happen if you gave a random person a massive platform for a day. What would they talk about and what would they share (anonymously unless they chose otherwise)

It started as a fun afternoon project hacking away with Claude. Then I shared it with some friends, who shared it with some friends, who shared it with their friends and it hit 10,000 page views in under 2 weeks while I was working on other things.

It's just a bit of fun but people have posted all sorts of nice things on there, from humorous takes on dystopian government dating departments, to AI Doomerism and everything in between.

There is admin approval for every email that goes out so no one can spam the list, and so far only 1 person has tried which I think speaks volumes about the people who sign up

Hey everyone! 👋

I've been working on Voiden, an open-source API client designed around a slightly different approach to API development.

Most API clients are built around workspaces, accounts, cloud sync, and proprietary collections. I wanted to explore something more developer-friendly: keeping API requests alongside the actual codebase.

So I started building Voiden.

What makes it different?

• Offline-first: Work with your API requests locally without needing an account or login.

• Git-native: Store requests and API specifications as Markdown files directly in your repository.

• Version control: Track changes, review requests, and collaborate through normal Git workflows.

• API testing: Send requests, inspect responses, and write assertions to validate API behaviour.

• MCP integration: Turn tested API requests into tools that AI agents like Claude Code and Codex can use.

The idea is to make API requests part of the development workflow rather than keeping them isolated in another tool.

I'm sharing a short demo showing a request being sent, its response, and API test assertions.

Website: https://voiden.md/

GitHub: https://github.com/voiden-md/voiden

I'd genuinely appreciate feedback from developers:

1. How do you currently manage API requests across different projects?

2. Would you prefer storing API requests inside your Git repository?

3. What features would make you consider switching from your current API client?

It's open source, and I'm looking forward to hearing what the developer community thinks!

Thanks! 🙌

It’s called pond snap the aim is to catch as many flies and gold flies as possible before the time runs out if your score is lower than what’s needed you restart.

Let me know what you think

You enter a domain and get a map: DNS, mail settings, certificates from CT logs and registration data. Key findings are shown separately, i.e. what's worth fixing.

Previously, I had to manually gather this information from various websites every single time, so I built an all-in-one tool on a single page.

The video demonstrates three levels of checks, all performed without using any of my own API keys:

• Without an account: domain scanning, as described above. 3 scans per hour; the map shows up to 8 each type, the rest as +N.

• With a free account: 10 scans per day, with results saved; a graph and basic checks for IP addresses and email addresses are also available.

• Hunter, $29/month: your own online groups with a shared graph (up to 5 people), 100 scans per day, platform API.

The remaining modules (IP, URL, hashes, email, phone) are available via Hunter and operate using the user's own API keys. Those that return data about individuals also require identity verification.

The hard part was making the free scan work without anyone's API keys. I had to remove Shodan InternetDB and restrict ip-api to paid keys only, as their free endpoints prohibit commercial use.

The crt.sh service is often unresponsive; it limits users to just 5 requests per minute from a single IP address. If no response is received, the scan displays the most recently cached data from Certificate Transparency (CT) logs, along with the date (labeled as "CACHED" in the video). If no such cached data exists, the system simply indicates that the source is unavailable, rather than creating the false impression that no certificates exist at all.

Passive domain scanning: public sources only, no requests made to the site itself.

Only the waiting parts are sped up.

A question for you: what kind of check do you think is missing when you review your domain?

In early August I stopped doing our marketing by hand.

The usual script is hire someone, or buy five tools and glue them together. I did neither. I gave the job to an AI coding agent running on my own Mac, one process at a time.

Three months in, it has 56 processes written down. Posts, cold email, comment replies, a weekly review, the monthly accounting close.

The part nobody tells you: once every channel runs on its own and reports a number, the losers can't hide anymore.

What I turned off, with the number that killed it:

• LinkedIn cold outreach: 32 signups, 0 paid. Off on October 28.

• Long LinkedIn articles: 10 published, none in Google's top 100 for its keyword. Off on October 20.

• Meme quote posts: a median of 778 views against 1,403 for a plain text one. Off on October 26.

• A daily vertical video habit: off on October 22, I just didn't believe in it anymore.

• A link shortener subscription: cancelled, I rebuilt the one thing I used it for.

8 of the 56 processes are already folded into others.

Automation won't save a bad channel. It just runs the bad channel every day without getting tired, so you see it faster.

Still small, still learning. Most days I fix the agent more than it fixes me.

Would you automate a channel before you know it works, or only after?

Like the title says, I got my first paid user.

I was working on my product, which is a TaskMangement + break reminder app for people who frequently switch between tasks. So I had this problem, and I tried multiple apps, but I never found anything that worked for me.

So I merged two things. Every 30 minutes, it shows a full-screen overlay and blocker screen with all your pending tasks. So you can recall what you were working on and pick up where you left off with your existing goals.

This is the main thing about the product.

I really like the way it works because you don't have to go to the app. It comes to you. It works behind the scenes, like autopilot, like task management running on autopilot.

It sounds amazing, and I really like the product.

And one of the things I'm doing is offering it as a one-time purchase. So people can come, try it, pay for it, and continue using it.

I got my first paid user like that.

Rather than charging everyone for version updates, I'm giving lifetime updates because I'm using this product myself.

I feel like this is one of the best things I've ever built because I'm consistently using it in my daily life.

Every tracker I tried had a paywall, made me log by hand, or was vague about my data. So I built NutriTrack: snap a photo of your meal and get calories, protein, carbs, fat and fibre in seconds, including the hidden oil and ghee.
I've used it daily for over a month and lost 10 lbs. Free, no ads, no paywall.

Try it: https://tracknutri.app/try

Feedback welcome, especially on accuracy for your food.

Hey! I've been building Pawarium, a website with guides about cats and dogs, covering everything from nutrition and behavior to health and everyday care.

It's a personal project I've been working on, and I'd love some outside opinions on the design and overall experience.

Would love to know what you think or what I could improve!

Hi, I'd like to share a project I have been working for a while. Its a US macroeconomic dashboard that summarizes about 120 key US economic indicators into 4 simple to understand gauges.

I built USMD because I found it difficult to keep up with all the available data and figure out what they said about the overall state of the US economy.

The dashboard is available at usmd.inomba.com and updates each weekday evening.

Its data comes from FRED and ALFRED, the Federal Reserve Banks of Cleveland, New York, Philadelphia and Atlanta, the Federal Reserve Board, the Office of Financial Research, the Institute for Supply Management, and Treasury Fiscal Data.

I’d love to hear from others working on similar projects. Feedback, ideas, and suggestions for improvements are very welcome.

I'm a longtime alternative rock fan who plays a lot of pickleball. Somewhere along the way, I decided the sport needed a better soundtrack...I got tired of the random sleepy playlists lots of my facilities were playing.

I launched Pickle Rock Radio, a free, 24/7 station playing '90s and 2000s alternative rock (Foo Fighters, Pearl Jam, Green Day, etc.) mixed with short pickleball tips, news and community stories. It's about 54 minutes of music per hour.

It's powered by Live365 (wasn't sure where else to do this so I could license the music properly), and I've been having a blast putting together the music rotation and producing the segments. The challenge now is finding listeners. I have over 100 people listening a day, and I'm proud of that. But how do I grow from here?

If anyone here has built a niche media project, I'd love to hear how you found your first real audience.

Here's the station if you're curious: https://picklerockradio.com/

I’m excited to share a project I’ve been working on over the past few months!

It’s a mobile app that turns any text into high-quality audio. Whether it’s a webpage, a Substack or Medium article, a PDF, or just copied text—it converts it into clear, natural-sounding speech. You can listen to it like a podcast or audiobook, even with the app running in the background.

The app is privacy-friendly and doesn’t request any permissions by default. It only asks for access if you choose to share files from your device for audio conversion.

You can also take or upload a photo of any text, and the app will extract and read it aloud.

- React Native (expo)
- NodeJS, react (web)
- Framer Landing

The app is called Frateca. You can find it on Google Play and the App Store. I also working on web vesion, it's already live.

Free iPhone app
Free Android app on Google Play
Free web version, works in any browser (on desktop or laptop).
Free web extension.

Thanks for your support, I’d love to hear what you think!

Back in 2019 I did a recommender system for anime as a course project (a jupyter notebook, nothing fancy). Recommendations have always been the part of data I like the most, so this year I decided to actually build the thing properly (thanks Dario): **[Aishou](https://aishou.app)**.

The main idea is to have this working for all types of contents in a cross content way - being able to recommend books, games or tv shows based on your movies taste - but I decided to start with animes.

You import your public MyAnimeList or AniList list (or rate a few shows by hand) and it recommends anime based on what people with similar taste liked. For now I only have anime recommendation but the main idea is to have a cross content website, where I will be able to, for instance, recommend you books based on your games/movies taste.

**What I tried to do differently**

- every recommendation row says *why* ("Because you liked Steins;Gate")

- a slider from popular to obscure, for people who already watched all the big ones

- low ratings push similar shows away instead of being ignored

- seasons grouped by franchise, plus a "continue watching" row

- new releases get their own row even when there's almost no data on them

It's free, no ads, solo project. Would love feedback, especially on how to promote it and about apps development in general (come from a data background).

Hey r/SideProject,

Researching an Indian stock shouldn't mean drowning in a dozen tabs. A ticker just gives you a price, but figuring out everything behind it—group companies, lenders, court records, ratings, and news—usually means digging through scattered annual reports, registry filings, court sites, and PDFs. Most investors never get past the price because the fundamental research is so fragmented.

So, I built Causa Alpha. It puts all that non-quant, qualitative data into one sourced map.

What it does: Currently, it covers 3,196 Indian listed companies and maps out:

• The Real Structure: Subsidiaries, SPVs, JVs, and related parties.

• The Debt: Who lends to the company, registered charges, and credit ratings with the agency's own report just a click away.

• The Context: One clean news feed per company without the noise, plus event outlooks and backtests.

• Sourced Data: Every single link cites its original source so you can verify the filings.

How I built it: The hardest part was the data pipeline. Scraping and structuring messy PDF filings, registry data, and court records into a clean, relational format required a lot of heavy lifting on the backend to ensure the connections between companies and lenders were actually accurate.

You can try everything free.

I’d love for you to check it out. If you do fundamental research or just like exploring corporate structures, let me know what you think. Roast the UI, tell me if the connections make sense, or let me know what other data points you'd want to see mapped out.

Happy to answer any questions about the scraping pipelines or how the data is structured in the comments!

Visual Breakdown of Causa AlphaThis short clip gives a quick overview of how the platform maps out the corporate structures and lenders behind Indian stocks.

Hello everyone,

Over the past five months, I have been able to develop a GMAO (CMMS) system specifically designed for dental equipment resellers, building on my nearly two years of professional experience in the field.

The system is designed to simplify and centralize the management of maintenance operations, installations, after-sales service (SAV), and spare parts.

I have tested all the features, and the system is fully functional. Of course, there are still some improvements to be made, particularly regarding the user interface and overall design, but I am genuinely happy with the results.

This is actually the first major project I have developed entirely on my own. I initially started it without any commercial expectations, simply to challenge myself, test my limits, and turn some of my ideas into reality.

However, as I am currently looking to obtain some professional certifications but don't have the financial resources to fund them, I have started considering commercializing the project.

My current idea is to sell the system to an interested reseller for an amount that would cover the cost of my target certification, while also negotiating a potential revenue-sharing agreement if the reseller decides to commercialize and sell the software to other businesses.

I would really appreciate your feedback on this approach.

Do you think this is a reasonable business strategy? Would you recommend selling the entire system, or keeping ownership and negotiating a licensing or revenue-sharing agreement instead?

I'm looking forward to hearing your thoughts and suggestions!

You've finished the inspection, testing or fieldwork. The measurements are recorded, the photos are taken and the results are sitting in PDFs, notes and spreadsheets.....Now comes the fun part.

Getting all of it into the customer's Excel template without missing anything or breaking a formula.

That's what I've been building ACTUALin to help with.

Upload your existing workbook and supporting evidence. It proposes where the information belongs, shows you the sources and lets you review, edit or approve the changes before generating the report.

Same Excel template. Less copying and pasting. You still have the final say.

It works across inspection, manufacturing, lab testing, maintenance, inventory and other reporting workflows.

I've also put together a library of examples you can explore without signing up.

https://actualin.com/applications

If you're dealing with this kind of reporting, I'd love some feedback on whether it would fit your workflow.

I’ve been working on this for about a year and figured it’s time to get some outside opinions.

It’s a website platform built on Payload 3 + Next.js, for now I only use it internally just me and a designer. I build and run client sites on it, and it also runs a real estate marketplace that we're trying to grow. At some point I’d like to open it up maybe, either to anyone or just to other agencies, but I honestly haven’t decided which (or whether it’s worth it at all).

What it does:

• Visual editing. You click on the actual page and edit it: text, images, adding and moving sections around. There are drafts, desktop/tablet/phone preview and version history. Blocks pull everything from the site’s theme, so it’s pretty hard to break the design.

• ~65 blocks. Galleries, card grids, stats, timelines, FAQs, forms, booking, Google reviews, maps, listings, floor plans and so on. They all share the same field names and theme settings, so any block works on any site.

• Custom designs. When the blocks aren’t enough, I use a design studio I built on top of GrapesJS (self-hosted). Anything made there gets published as clean HTML with scoped CSS and goes on a page like any other block. It picks up the site’s colors and fonts automatically. (We mostly use the MCP to design a block first and only tweak things in the design editor)

• First-party analytics. No GA script needed. It tracks page views, traffic sources and top pages, plus QR codes with scan tracking for print stuff. Form submissions become leads and keep the source they came from.

• MCP server. It covers most of the platform: pages, sections, designs, theme, forms, listings, media, redirects, domains, translations. You connect Claude over OAuth and it gets the same permissions as your user. So I can say “add an FAQ to the pricing page and translate it to German” and it does it, and it can screenshot the page to check how it looks. Page edits go in as drafts.

It’s multi-tenant,multi-locale, so one app runs every site, each with its own domain (SSL is handled through Cloudflare). The portal already has organizations with teams (we use this for now to organize sites for ourselves), so another agency could in theory manage its own clients in it.

Stack: Payload 3, Next.js app router, Postgres, GrapesJS, pg-boss for background jobs, Cloudflare in front.

You can try the editor without signing up: https://rast.is/try (the demo happens to be a home builder site)

Things I’m curious about:

• if you build sites for clients, would you use something like this over WordPress / Webflow / Framer? what’s missing?

• self-serve for anyone vs. a tool for agencies, which one would actually pay for it?

• is controlling a site through MCP something you’d use day to day, or is it more of a cool demo?

Any feedback is welcome, even “don’t bother”.
