Both directions
The target your callers hit and the source that calls your services — one relay, four shapes.
Webhook relay service
A webhook relay service for both directions.
EchoRelay sits in the middle of your HTTP traffic — the target your callers hit and the source that calls your services. One authenticated layer that fans out, streams, mirrors, and shields, so you don’t build the plumbing.
Why EchoRelay
Less to build, less to run.
Authenticated and validated
Every request is authenticated, validated against your rules, and rate-limited before it moves.
Delivered at-least-once
Retries with backoff and a replayable dead-letter queue — nothing silently dropped.
Questions
Answered, honestly.
- What is a webhook relay service?
- It is a managed layer between your callers and your services that authenticates, validates, and delivers HTTP traffic — fanning out to many targets, streaming responses back, mirroring, or shielding your origin — so you don’t build that infrastructure yourself.
- What can EchoRelay’s relay do?
- Four shapes: fan-out (one request to many targets), streaming (forward an SSE or chunked response back), mirror (live plus a shadow copy), and origin shield (take inbound traffic without exposing your servers).
- Where does EchoRelay run?
- Production runs in the EU (Hetzner, Nuremberg) today, with additional regions on the roadmap.
