PIIXEL // BUILD ENGINE

Describe it. Ship it.

The AI app builder that validates every change before you pay for it.

Keep 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.

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.

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
