Build with AI. Without the decay.
The open-source runtime whose structure keeps AI-generated software coherent in production, instead of collapsing into a mess no one can change. Self-hosted, and yours.
Until it falls apart.
Wippy's answer is constraint. An actor model isolates every part behind messages, so one piece can't tangle another, and what you build holds as it grows, however far you push it.
Structure the AI
can't break.
Left alone, AI code drifts toward entropy. Wippy's structure won't let it: four properties baked into the runtime, not conventions the AI has to follow.
No shared state
Parts talk by messages, never by reaching into each other. A change here can't silently break there.
One shape for everything
Every part is one kind of registry entry. The AI can't invent five ways to do one thing. Every generation lands in the same mold.
Security is a capability
Each part runs with only the capabilities you grant it. No ambient power, nothing it can reach that you didn't hand it.
No integration tax
New parts register and wire themselves in through their contracts, instead of you gluing services together by hand.
Claude Code and Codex edit it live.
Your agent doesn't guess at Wippy. It reads the real docs and live project state over the Keeper MCP and edits the running system in place.
See everything it builds.
Roll back anything.
Hand the AI the keys without losing control. Every action it takes is traced and reversible.
Not markdown guardrails.
A runtime.
A general-purpose runtime in one self-hosted binary, with the AI toolkit built in. Everything below ships in the box.

Start from a working app.
Clone the template, point your coding agent at it, and build on top. The structure keeps what it generates coherent.
