EchoRelay

EchoRelay is a managed runtime for custom API integrations. You own a handful of adapters that break whenever a vendor changes something. We operate them instead.

One address in. Many systems out, each shaped by a configuration you can preview, publish and roll back. Deploy nothing.

Lines are versions of your API, v1 and v2, each with its own base URL. Build the next one beside the version that is serving traffic, then activate it when it is ready.
Set the target, how it authenticates, and whether it gets queued delivery, synchronous delivery or streaming. Anything still undelivered lands in failed deliveries.

A mapping is a tree of typed nodes. Edit it as JSON or build it visually. Both read back the same thing, so what an agent writes opens in the builder unchanged.

What is EchoRelay?

EchoRelay is a managed runtime for custom API integrations.

Describe one integration once: what comes in, the target system, credentials, the retry policy, and how the answer maps back. EchoRelay validates each inbound request, maps it, replies synchronously, passes streams through, fans out to multiple targets, or queues delivery with automatic retry, a dead-letter queue and replay.

Every configuration change is versioned. Preview, diff, dry run, schedule, publish and roll back. When a vendor changes their API or rotates a credential, you update the configuration and publish. Deploy nothing.

Build and operate each integration through the REST API, an MCP server so an AI agent can do the wiring, or the web panel. Free to start, no card required.
