The hosted control plane is open: sign in with GitHub and connect a repository.

Isolated Twin . A temporary copy of the application stack for every risky change.

Side-Effect Firewall . A stateful Stripe and captured mail instead of charging cards.

Load . Traffic shaped like production's own access log, sent at the twin.

Migration Safety . Locks, table rewrites, and query plans before it ships.

A risky pull request, stopped before it merges. Eighty five seconds.

Antifailure makes a copy of production, the same size and the same shape and the same load, with every real name replaced. Your change runs there first, on every pull request, before it merges, whether a person wrote it or an agent did. Then the copy deletes itself.

Migration Safety. Catch exclusive locks before they take checkout down. The strongest lock held per table, whether another session was left waiting on it, and how the plans moved.

Widen plan_id on subscriptions and measure the exclusive lock, whether another session is left waiting on it, and whether the table is rewritten before the change ships.

ACCESS EXCLUSIVE held 27.4s, and another session was seen waiting on it even on the branch.
