Micro-apps. Weekly.
Ideas are easy.Launching isn't.
Built By Sunday finds a problem worth solving, builds one focused micro-app, and shows the whole launch—every single week.
Small community. Big impact. One launch at a time.
This week's mission
Find the niche. Ship the app.
> Scanning micro-communities...
> Validating painful work...
> Building the smallest useful tool...
> Launch window: 48HRS.
Built for people who would rather ship than speculate.
48 hoursOne hard deadline. Zero room for bloated scope.
100% publicThe decisions, misses, launches, and metrics stay visible.
The build system
A builder's frame for turning ideas into launched apps.
We do not chase generic software ideas. We work backwards from a community, a painful job, and a simple outcome people can use.
- 01
Map the pain
We listen for the expensive, repeatable annoyances hiding inside small communities.
- 02
Build the useful bit
A hard 48-hour constraint keeps every app narrow, practical, and ready for real people.
- 03
Launch it in public
The research, product calls, launch assets, and results stay visible from first signal to Sunday.
NEXT TARGET
Your niche could be next.
Every launch starts with one question: who is doing a painful, repetitive thing because nobody built the right small tool yet?
Why follow along
Watch the part most builders hide.
Build notes cover the evidence, the tradeoffs, the stack, and the numbers after launch—not just the polished final screen.
- No made-up revenue screenshots
- Every build has a sharp audience
- Real constraints, shared publicly
Next launch window opens soon
Stop waiting for the perfect idea.
Follow one sharp problem from its first community signal to a working app—and take the useful parts into your own work.
