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. When a field gets renamed, you edit the mapping and publish. Deploy nothing.

Features & Specs

  1. Versioned configuration

    Each integration is configuration, not code you deploy. Preview it, dry run it, publish it, roll it back.

  2. Request and answer mapping

    Reshape what comes in and what goes back. Edit the mapping as JSON or in a visual builder; both read back the same thing.

  3. Queued, synchronous and streaming delivery

    Queue a request with automatic retry, answer inline, or pass a stream straight through to the caller.

  4. Fan out to many targets

    One request in, delivered to every target you configured, each shaped by its own mapping.

  5. Delivery receipts

    Every delivery leaves a record: the target, the outcome, the attempts and the callback.

  6. Failed deliveries you can replay

    Deliveries that run out of attempts wait with their reason and payload. Replay one, or all of them.

  7. Credential vault

    Target credentials are stored sealed and can be rotated without touching the integration that uses them.

  8. REST API, MCP server and web panel

    Build and operate an integration from code, from an AI agent, or by hand. All three edit the same versioned model.

Questions & Answers

As answered by people managing EchoRelay.
  1. What makes EchoRelay unique?

    What costs you money in an integration is not building it, it is the week a vendor renames a field. EchoRelay holds each integration as configuration instead of code you deploy: what comes in, where it goes, how it authenticates, what happens when the target is down, and how the answer maps back. Change any of it, preview the diff, publish, roll back if you were wrong. Deploy nothing. Every request leaves a delivery receipt, so when someone asks whether an order reached the warehouse, you answer from the record rather than from the logs.

  2. How would you describe the primary audience of EchoRelay?

    Software teams that maintain a handful of custom integrations and have nobody whose job that is. There are developers, which is why they can run a runtime and read a mapping, but no integration team, so every vendor change competes with the product roadmap for the same people. Typically a shop wired into an ERP, a tax office, a fulfilment partner and a few marketing tools, or a product reselling a dozen vendor APIs behind one format of its own.

  3. Why should a person choose EchoRelay over its competitors?

    Most alternatives are one of two things: a catalogue of prebuilt connectors for popular products, or a workflow canvas. Neither helps with the adapter you had to write yourself, because the system on the other end is a customer's ERP or a partner's ordering API that nobody ships a connector for. EchoRelay is for that one. You describe it once and we operate it. The real comparison is the adapter service you would otherwise build and maintain in-house, and the difference is that a schema change becomes a mapping edit instead of a release.

  4. What's the story behind EchoRelay?

    It started from a pattern that shows up in almost every software team that talks to systems it does not control. The integrations that hurt are never the popular ones with a ready-made connector. They are the customer's ERP, the partner's ordering API, the tax office endpoint: one-off adapters somebody wrote once and now nobody wants to own.

    The cost is not writing them. It is everything after. A vendor renames a field and someone edits adapter code, deploys it and hopes nothing else moved. A credential rotates and the adapter quietly breaks until a customer notices. The vendor has an outage and the retry logic you wrote yourself has to absorb it. Then someone asks whether an order actually arrived, and the honest answer is buried in logs.

    EchoRelay was built to move that work out of application code. Describe the integration once as configuration: what comes in, where it goes, how it authenticates, what happens when the target is down, and how the answer maps back. When the vendor changes something, you change the mapping, preview the diff, publish, and roll back if you were wrong. Deploy nothing. Every request leaves a delivery receipt, so the question about that order has an answer you can point at.

  5. Which are the primary technologies used for building EchoRelay?

    Nothing you have to install or operate. From the outside EchoRelay is plain HTTP: a REST API, an MCP server so an AI agent can do the wiring, and a web panel. You send a request to an address and we handle the rest.
