Two universes, never mixed
Your code runs in isolated microVMs on the substrate. Our platform never executes user code. Secrets are session-scoped and rotated on end. The security boundary is non-negotiable.
Platform → Django, Postgres, auth, billing
Sandbox → user repo, microVM, mitmproxy
Never mixed.
