Where the logic actually works
A utility, tool or small game where the behaviour matters, built and fixed in a loop until it actually runs, with a live preview.
Generated apps that look right and break
For anything interactive, the hard part is the logic actually working.
Logic that doesn't hold
Generated interactivity often looks fine and falls apart on the first real click.
Debugging by hand
When it breaks, you're stuck reading errors you didn't write.
Risky iteration
Changing a working app can break it, with no safe way back.
How Build makes it actually work
An agent runs the app, reads the errors and fixes them, with safe iteration.
Describe the app or game
Say what it should do and how it should behave.
Build it in a live preview
Watch a real multi-file app build and run as it writes.
Make it work
An agent runs it, reads the errors and fixes them in a loop until it runs.
Iterate safely
Branch and compare versions so changes never lose a working build.
Everything in this workspace
- Behaviour and logic that actually work
- The agentic make-it-work loop: run, read errors, fix
- A live preview and a visual editor
- Branch and compare to iterate safely
- Owned files, deploy when ready
Build something that actually runs
Describe it, and let the make-it-work loop do the debugging.
