Signed deliveries
Every attempt carries a signature and a receipt the receiver can verify.
01Webhook delivery with proof
Signed retries and dead-letter replay, so no event silently vanishes into the void.
Zeusbolt is the boring, load-bearing part of webhook delivery with proof. Built by a small team, shipped weekly.

What you get
Three things Zeusbolt does properly.
Retries with backoff
Capped, jittered and visible — not a black box that gives up silently.
02Dead-letter replay
Replay a failed batch after the fix, with the original payloads.
03“Our customers stopped opening tickets about missing events. They verify the signature now.”

Can I see a failed delivery?+
Request, response, headers and timing, for 30 days.
Zeusbolt is open for design partners.
Small team, direct access to the people who build it. Bring a real workload.
