Kisenon is branchable serverless Postgres. Cold endpoints wake on first connect. Branches in seconds. Pay storage only — idle compute is free.
Idle endpoints suspend after 5 minutes. Pay storage only — no per-hour compute floor. The OG noble-gas idea.
Cold start is measured at the wire, not at process boot — fast enough that ORMs never see a timeout.
Branches are pointers, not copies. Spin one up, run a destructive migration, throw it away. Free below the delta.
