My youtube Watch Later has 2000+ videos and I still couldn't find a podcast for a ride, so i made an extension to fix it

My Watch Later has like 2,000+ videos in it, and honestly I try not to save more, for exactly that reason. The bigger it gets the less chance I have of finding anything in it again. Anyway, I was heading out on a bike ride the other day and wanted a podcast for the road. 2 hour ride ahead, and all I could dig out by scrolling was a couple of 20 minute videos. That was the moment. I just wanted to filter the thing down to podcasts and hit play. So I built an extension that does that. You run ...

What 8 months of AI-handled intake calls actually looked like

An early stage law firm I work with had a front office problem relating to missed calls. The founder put it plainly: "a number of potential clients were lost, especially in time-sensitive matters where people move on quickly if they don't reach someone live." The solution I proposed was an AI voice agent to cover the overflow and after-hours calls, as those were the lowest risk and were being missed anyway. The goal was to have it run their intake process end to end. That meant it ...

Google Flights hides the cheapest way to travel Europe — so I built a tool that finds it

Hey r/SideProject , Solo dev, this is my project after a few months of nights-and-weekends work. The problem: the cheapest way to fly around Europe is usually not one ticket — it's chaining separate low-cost flights (Ryanair, Wizz, Volotea, easyJet, Transavia…) with self-connections. Google Flights and Skyscanner hide these because they only show single through-fares. Finding them by hand = testing dozens of connecting airports and dates. What I built: you enter your departure airpo...

I built a free Chrome extension to watch any video in sync with friends

I made a Chrome extension called Watchbear that lets you watch any video in sync with friends, and I finally got around to making a short video showing how it works. The idea is simple. You open a video, start a room, and share the code. Everyone who joins stays on the same frame. Play, pause, and seeking stay in sync for the whole room. There's also a side panel for chat and quick reactions, and it shows the current second of whatever is playing in the active tab. I built it mostly because ...

I’m celebrating 4 users

Three years. Bootstrapped. Solo. Today, four people I don’t know signed up. I know some people will read that and think, “Only four?” I don’t. Those four people mean the world to me. Building a startup demands discipline, consistency and obsession. None of those are easy to sustain. So when something gives you fuel, use it. Celebrate it. Don’t wait until 1,000 users before you’re allowed to enjoy the journey. Today I feel like a brand new founder. What wins encouraged you along the j...

How do you validate your idea and how can you be sure it won't be stolen while validating ?

Hi, after a few failed attempts at building my own application (for several reasons) I have started feeling like every idea that comes to my mind has flaws and nobody will use those applications. What are your tactics to validate your idea so you can understand that its not just a good feature rather its a good opportunity users are willing to pay ? And while doing so how can you prevent your idea from being stolen ? [link] [comment...

Why do we build for months then freeze the second it's time to get users?

Shipped it. It works. People would actually find it useful. Then launch day hit and suddenly I had a very urgent list of "small improvements" to make before I start outreach. There's something broken in the builder brain. Coding has instant feedback — you build something, it works, you feel like a god. Marketing? You post, nothing happens, you question your entire existence. I know the product is good. I know people need it. I literally made the core feature free and unlimited so...

Shipped Town: a browser game that turns your life, project, or hobby into a walkable AI town

I shipped Town this week. It turns your world into a tiny pixel town you can build, share, and fill with AI characters people can actually talk to. You get a browser-native little world with buildings, NPCs, and multiplayer visitors. Someone can open your link, walk around your town, chat with you if you’re online, or walk into a building and talk to one of your AI characters. I built it because profiles, landing pages, and “about me” pages all feel weirdly static. If someone wants to under...

I Built a streaming multi-viewer!

I have been working from home for over 6 years now, and I got sucked into the streaming world (not a streamer) just enjoy watching streams in the background while I work. The issue I found was I was always using multiple tabs between youtube, kick and twitch and organizing the windows to fit my screen the way that I wanted them to. So I build my own multi-viewer that allows you to login to twitch and kick and automatically select the streams you want to watch, and you can paste in the yout...

I made a small Windows tool that turns the edges of your touchpad into sliders for brightness and volume

Left edge controls brightness. Right edge controls volume. That's about it :) It requires Windows 10/11 and a Precision Touchpad. It lives in your system tray and stays out of the way. Normal touchpad behaviour is completely untouched—scrolling, pinching, multitouch, all work as usual. EdgeSlide only fires when one finger starts at the very edge. No installer, no account, no telemetry. Free, open source, portable exe. → GitHub: https://github.com/puttingpixelstogether-ops/edgeslide ...

Website to find smoke-free terraces - first project, looking for honest feedback

Hi everyone, I recently built my first side project and I’d really appreciate some honest feedback before I start sharing it more widely. Quick backstory: I'm into sports and health and basically hate cigarette smoke when I sit on a terrace. So I built ClearAir Tables ; a way to find restaurants and cafés with smoke-free terraces. The idea came from wanting an easier way to find outdoor places that feel comfortable for people who avoid secondhand smoke, whether for health reasons, kids, pre...

Hello everyone, There are two things I really love to do when I am free: watch football and figuring out which AI models are good. The World Cup felt like the perfect excuse to mash them together. So I set up seven models (GPT-5.5, Opus 4.8, Gemini 3.1, plus a few open source ones) as rival gamblers. Every model gets a $1000000 in virtual cash and has to survive the whole tournament. Before every match they're handed the same scouting report and have to commit to a prediction without seein...

I spent months building a CLI that tells you which parts of a codebase are becoming risky to maintain

This started as a small experiment and turned into a much bigger project than I expected. The tool is called git-archaeologist. It reads git history and tries to answer questions like: What parts of the codebase depend on one person? Has that person actually been active recently? Which areas are accumulating maintenance risk? Which files tend to break together? Where is knowledge becoming concentrated? One thing I learned while building it: The scary code isn't always the c...
