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.

EchoRelay.dev features and specs

  • Versioned configuration
    Each integration is configuration, not code you deploy. Preview it, dry run it, publish it, roll it back.
  • 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.
  • Queued, synchronous and streaming delivery
    Queue a request with automatic retry, answer inline, or pass a stream straight through to the caller.
  • Fan out to many targets
    One request in, delivered to every target you configured, each shaped by its own mapping.
  • Delivery receipts
    Every delivery leaves a record: the target, the outcome, the attempts and the callback.
  • Failed deliveries you can replay
    Deliveries that run out of attempts wait with their reason and payload. Replay one, or all of them.
  • Credential vault
    Target credentials are stored sealed and can be rotated without touching the integration that uses them.
  • 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 LocalXpose and EchoRelay.dev.

How would you describe the primary audience of your product?

LocalXpose's answer

LocalXpose serves two main segments: (1) Full-stack developers who need reliable webhook testing and API development tools, and (2) B2B technology integrators managing distributed systems - particularly in restaurant POS, retail systems, industrial IoT, and building management. LocalXpose is built for technical teams at growing companies who need enterprise reliability without enterprise complexity.

EchoRelay.dev's answer:

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.

What makes your product unique?

LocalXpose's answer

LocalXpose provides managed tunneling infrastructure that bridges the gap between consumer-grade tools and enterprise complexity. LocalXpose offers production-ready tunneling with UDP support, custom domains, and white-label options, while maintaining the simplicity of setup that developers expect. Unlike self-hosted alternatives, LocalXpose handles all infrastructure, SSL certificates, and scaling automatically.

EchoRelay.dev's answer:

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.

Why should a person choose your product over its competitors?

LocalXpose's answer

Choose LocalXpose if you need reliable tunneling without the operational overhead. LocalXpose is excellent for webhook testing, remote device management, and B2B integrations. Key advantages: production-ready from day one, UDP protocol support (rare among competitors), transparent pricing without usage surprises, and responsive founder-led support. Best fit for teams that need tunneling to work reliably without becoming networking experts.

EchoRelay.dev's answer:

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.

What's the story behind your product?

LocalXpose's answer

"LocalXpose was founded to solve a frustration we experienced firsthand: existing tunneling solutions were either too unreliable for production use or required extensive networking expertise to deploy. We built LocalXpose as the tunneling service we wished existed - powerful enough for production, simple enough to start using immediately, and backed by support from people who actually understand the technical challenges our customers face."

EchoRelay.dev's answer:

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.

Which are the primary technologies used for building your product?

LocalXpose's answer

LocalXpose runs on a distributed architecture using Go for high-performance tunnel servers, with automatic SSL certificate management via Let's Encrypt. The service supports multiple protocols including HTTP/HTTPS, TCP, and UDP (unique among major providers). The client application offers a GUI with request/response and webhook inspection tools, and supports enterprise features like custom domains and IP whitelisting.

EchoRelay.dev's answer:

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.

Who are some of the biggest customers of your product?

LocalXpose's answer

  • multi-location restaurant chains using LocalXpose for POS management
  • home automation and security products integrating on-site, cloud, and mobile applications
  • managed service providers (MSPs) in the retail POS industry
  • IoT platform providers connecting industrial equipment and facilities management applications
  • development teams at fast-growing SaaS companies testing payment integrations and webhook workflows

Best ngrok alternatives for localhost tunnels
LocalXpose is a reverse proxy tool that provides a public URL to localhost. By simply downloading their client you can create HTTP / HTTPS tunnels, and also TCP / TLS as well as UDP tunnels. Among the three it is the only one that supports UDP traffic. LocalXpose also provides a built-in file server to share your files instantly.

5 Free Tools to Expose localhost to Internet
LocalXpose is the last tool in my list and a simple reverse proxy that helps you expose localhost to the internet. This is a different tool than others I have mentioned in the list. The best part is that it comes with a GUI. You just have to select a protocol from the lost, specif the localhost address there and then you are done. It is great, however, in the free plan of...

  • Tunnl.gg
    The tunnel host appears to be a Hetzner server, they are pretty generous with bandwidth but the interesting thing I learned about doing some scalability improvements at a similar company [0] is that for these proxy systems, each direction’s traffic is egress bandwidth.

  • T-Mobile Enhances 5G Home Internet with Advanced Modems
    I would assume not. They seem to be CG-Nat based modems, you'd need to invest in solutions like localxpose or gaming vpns like Cyberghost VPN if you need ports. I don't think CG-Nat will ever support port forwarding. Source: about 3 years ago
