A couple of weeks ago ChatGPT opened their ads platform to the public (it used to be open only in Beta or with large minimums). Interestingly enough it has a standard UI (campaigns, ad groups, ads) But they also launched an advertiser API. I work on the product side mainly (one of my co-founders is a developer) but the API felt pretty accessible (REST + API key auth) - so I gave it a go. I used Claude Code to build an MCP for OpenAI ads - so I can manage them via a conversational UI. Did ...

Hi everyone, My name is Arkady, I’m 40 years old, and a few weeks ago I started building my first app. The funny part is that I have absolutely no background in software development. I’ve spent my entire career working in the oil and gas industry. But after turning 40, I started thinking about where my life was heading and what I truly wanted to do with the years ahead of me. Reaching that age made me realize something simple: none of us are here forever. Instead of just thinking about c...

I've been obsessively tracking YouTube niche data for months now. Not opinions. Not "I think this niche works." Actual CPM data, growth rates, competition scores, and revenue potential — updated twice daily. Here's what I found. And honestly, some of it blew my mind. The niches EXPLODING right now (real growth rates): Niche CPM Growth Betrayal & Story Narration $18 +310% English Learning Content $7 +288% AI Video Production $16 +250...

As a student, I kept getting distracted whenever I studied alone. Over the past few months, I've been building an app that makes studying feel more social and game-like. Feature already have: Focus sessions with friends Gamified study challenges AI study assistance Personalized learning support What would make you actually use something like this?

Hello r/SideProject , Been building Tracio on the side while studying software dev and it's finally live. Made a quick preview of what it looks like in action, time tracking, invoicing, project management and business reports all in one place. Built it because I needed it as a freelancer and nothing else felt right for a solo operation. Still early, still improving, would love to know what you think. What's missing? What would make you actually use this every day? hitracio.com — 14...

I like this subreddit, but sometimes it feels like the front page gets completely dominated by things Claude coded in 5 minutes, silly/meme apps (which can be cool, but not actually useful long-term) or low-effort AI wrappers that nobody will use next week. I want to see the tools that solve an actual, painful problem and something that you poured effort into. Drop your project below, but tell me what is the practical problem it solves and who is actually using it? I’m a teen programmer m...

Vaults.lol - free link in bio with music, video backgrounds, analytics, and no subscription. Ever. Most link in bio tools have the same problem. They start free, lock the actually useful stuff behind a monthly plan, and by the time you realise you need those features you are already paying $8 to $15 a month for a page that shows your Instagram link. Vaults.lol takes a different approach. The core product is free forever. No credit card, no trial period, no features that quietly disappe...

At the start of 2026 I wanted to finally get into bullet journaling. Since i tend to forget my physical journal, i was looking for an app that lets me bullet journal. But every app I tried was either behind a paywall, too complicated, or just not what I had in mind. So I did what any reasonable person does – I spent the last few months building my own. The idea is simple: one pixel per day. You create trackers for whatever you want – mood, sleep quality, whether you worked out – and each d...

most agents are decent at coding now, but once u throw them onto real websites everything gets messy fast. tabs everywhere, random popups, login sessions timing out, redirects, forms breaking, payment pages, all that stuff. been messing around with Ego Lite lately and the interesting part is it gives agents their own isolated browser space instead of hijacking ur actual browser/session. in the demo it searched flights on Expedia, filtered nonstop flights, sorted cheapest first, filled passeng...

For years our family calendar has been a big paper one on the kitchen wall. Two parents, five kids, and every activity, appointment, and school thing gets scribbled on it. The problem: only my wife and I ever actually look at it — and the second you leave the house, all that info is stuck on a wall at home. Miss the wall, miss the event. So I built SnapEvent. You take a photo of the wall calendar (or a school newsletter, a flyer, a screenshot from the group chat) and it reads the events — name...

Hi Everyone, I have been working Reloops from past six months and have recently open sourced it . I have been trying to find a full open source self hosted version for frame .io or other collaboration / review tool but couldn't find ones that provided all capabilities out of the box. The one I found were outdated or missing other key features that freelancers will need like notifications, email notifications, mentions, collections, and digital asset management features. I also added ...

Going up against Instantly/Smartlead. We built cold email infrastructure for founders who are tired of duct-taping 4 tools together. We're taking on Instantly & Smartlead with a tiny team. cold email should be simple. write a great offer. send it to the right people. get replies. grow revenue. but that’s not how it works today :( I have built something that helps you focus on the above & less with the setups without costing you a fortune. With Deliveryman.ai - You co...

I went on a walking tour in Columbia last year that was three 3 hours long, I only actually wanted go to a couple stops and by the end of it i was knackered, my girlfriend was miserable and then I was guilt tripped into tipping. Fast forward a year and a buddy and I have built "Roam" and just launched it on android/ios. You can draw an area on the map and it curates a list of possible stops and then allows you pick and choose what you want to see and then turns it into an audio tour ...

Last week, I posted a simple question on this subreddit and another one: "What's your MRR and how long have you been building?" To my surprise, there were 200+ comments, 50,000+ views, and 50+ founders who shared their real numbers from $4.99 to $510,000. Some posted publicly, and some DM'd me privately. The thread was genuinely helpful**,** and I learned a lot of things I never expected. So I decided to put everything together in one place. Here's the breakdown: The media...

ok so i have a bad habit of building tools instead of just using the ones that exist. but this one had an actual reason. every time i wanted to compress a pdf or pull the background off an image i'd end up uploading my file to some random server, sitting through ads, or hitting a "upgrade to download" wall. for anything remotely private that just felt gross. so i made footrue.com. everything runs in your browser, the file literally never leaves your computer. the two i actually use...

So Cloakly has been out of beta for a minute now, and the feedback loop is still completely unhinged. First, half the internet was convinced I’d built the ultimate interview-cheating machine. Now, I just got a massive essay from a remote manager arguing that tools like this are a "threat to team accountability" because colleagues have a right to see exactly what’s on your desktop during a live share. Honestly? Hard disagree. When I’m giving a codebase walkthrough or a live client...

A month ago I posted about building a job-search engine out of spite after Indeed laid off my wife at 7 months pregnant. FWIW, I still hate them. 130k people viewed that post and 750 have added their personal resumes. It's crazy how much the momentum motivates you to build, so thanks for the support. Since then, I brought on two dev friends to harden the system. It outgrew casual building and frankly I'd rather try to make it incredible vs. just existing as a side project. I took everyone...

Hey everyone, I've spent the last few months building KeepSoul — a digital legacy platform. The idea: a secure vault where you store passwords, write messages to be delivered in the future (a letter to your kid on their 18th birthday, for example), and plan who inherits your digital assets if something happens to you. This is NOT a promo post. I'm not trying to sell anything. I genuinely want honest feedback before I push further — what's confusing, what's broken, what's missing, what...
