Reverse-spec, rebuild, ship
Modernize your legacy app — without a rewrite team
Paste your app's URL or describe it. Agents reverse-spec the old system and rebuild it on a modern, maintainable stack — faster, cheaper, and fully reviewed.
What you get
Same product, modern foundations
Modern, maintainable stack
Off the legacy framework and onto a current, well-supported stack your team can actually hire for.
Every feature preserved
Reverse-spec'd from the live app so nothing your users rely on goes missing.
Full source & ownership
You get the complete codebase, documented and deployable to your own infrastructure.
Reviewed & secure
Multi-layer agent review and security checks before anything ships to production.
We rebuild as clean-room, original code on a modern stack from your own app's observed behaviour — your code stays yours, and the result is yours to own and modify.
How it works
From legacy to live in three steps
Point us at the old app
Paste its URL, or describe it if it's behind a login. We reverse-spec the current behaviour.
Watch the live analysis
Agents map the features, flows and data model, then plan the rebuild in real time.
Ship the modern version
Own the source, or run it in the cloud from $49/mo — migrated, tested and live in days.
