Workflows as code
Your notification logic is plain TypeScript behind one signed webhook — not a low-code editor you have to fight. palumb’s engine drives it durably; you branch, loop, and call your own code.
palumb
Notifications as code, sovereign in the EU. You write the workflow in TypeScript — palumb runs the durable control plane, the channels, and the delivery.
What you get
Section titled “What you get”Durable by default
Built on Restate. Steps survive restarts, retries are automatic, and sends are idempotent — no double emails after a crash.
You never touch provider keys
palumb owns the egress. You express intent (send to this subscriber);
palumb resolves the channel, decrypts the credentials, and makes the call.
Sovereign in the EU
A fully managed control plane, run in the EU, for teams that need their notification data to stay there.
