Plan → Patch → Prove
Every request becomes a reviewed plan, surgical SEARCH/REPLACE edits, then a real typecheck-lint-build gate. No blind whole-file rewrites, no silent breakage.
PIIXEL // BUILD ENGINE
Describe it. Ship it.
The AI app builder that validates every change before you pay for it.

Snapshots on every run. Full code export. Your code was never the hostage.
WHY PIIXEL
Built around the failures of the tools before it.
AI builders fail in predictable ways: they forget your codebase, rewrite files wholesale, bill you for their own mistakes, and lock your work inside their walls. Piixel is the countermeasure to each one.
Failed runs cost $0
If the proof gate fails twice, Piixel rolls your project back to the pre-run snapshot and bills nothing. You never pay an AI to break your app.
Never trapped
Git-native history, full code export, and a generated real backend (Hono + D1) you can eject anywhere. Your code was never the hostage.
THE DIFFERENCE
Why Piixel is different.
| Piixel | Most AI builders | |
|---|---|---|
| If the AI makes a mistake | ● Undone automatically — you're not charged for it | ● You usually still pay for the failed attempt |
| Before you see your app | ● We check it actually runs first | ● Shown to you unchecked — you find what broke |
| How the AI changes your code | ● Edits only what needs to change | ● Often rewrite whole files and break working parts |
| As your project grows | ● Keeps your whole project in mind | ● Can lose track and forget earlier work |
PRICING
Pay for results, not retries.
The meter only moves on verified runs. A run that fails its own proof gate is rolled back and costs you nothing — that is the whole point.
