Every AI builder generates code. Falken proves it works: an independent reviewer agent tests each build against your request and the builder rebuilds until it passes — or escalates to a stronger model. Watch the agent team work in real time.
Hey Product Hunt 👋 I'm Markus, exploring new things
I've tried most of the AI app builders. They're magic for the first 80% — then you hit the wall: the preview is blank, an import is broken, a button does nothing, and you're back to copy-pasting error messages hoping the next generation fixes it.
So I built Falken around one idea: the AI shouldn't just generate your app — it should verify it actually works, and rebuild until it does.
Under the hood, every build runs as a small team of agents (a coordinator plus specialists for code and design) on Claude. They build, grade the result against a rubric, catch what's broken, and iterate — before you ever see it. You describe an app or website, and you get one that actually runs.
A few things I'm proud of:
Verify-and-rebuild loop instead of one-shot generation
Attach images or docs as references or specs
Remix any public app to start from someone else's idea
It remembers lessons across your own projects
Free to try — 25 credits, no card. I'd genuinely love your brutal feedback: what breaks, what's confusing, what you wish it did. 🦅
Happy to launch and share this weekend project.
