Our verdict

Source reviewedReviewed 22 Oct 2026 by Enterprise DNA editorial

A small local proxy that lets coding agents such as Claude Code and Codex CLI switch between your GitHub Copilot, OpenAI, Anthropic, Z.AI, DeepSeek, Groq, Ollama and other accounts without a restart.

Best for: Developers with several provider accounts who want one local switch for their coding agent, on a machine only they use.

Choose something else if: you share a network or a machine, or you need a maintained tool. It is a one-person project with no tagged releases, and its Copilot route may conflict with GitHub's terms.

Source review

Using Relay in practice

Where it runs

Runs on your own computer. Requests go from the local proxy to whichever provider account is active.

How to install

Install Bun 1.2 or later, git and pnpm, then install Relay from GitHub. Add an account with relay account add, start the proxy with relay proxy start and point the agent at http://127.0.0.1:8787/api/anthropic or /api/openai/v1.

Install commands

pnpm install -g github:ImBIOS/relay

As published in the linked sources. Not run by us.

What it costs

Free under the MIT licence, with no paid tier. You pay for the provider accounts and subscriptions you connect.

Prices and plans change. Check the linked sources before committing.

Why consider it

  • Translates between Anthropic and OpenAI request formats, so one agent can use either kind of provider.
  • Switching or rotating accounts does not need an agent restart.

What to watch for

  • In the source we read, the proxy listens on all network interfaces unless RELAY_HOST is set, and its README says any string works as the key. Anyone who can reach port 8787 can use your accounts.
  • Provider keys are stored as plain JSON in your home folder.
  • Its GitHub Copilot route calls Copilot's internal endpoints with editor headers. Check GitHub's terms before using it.

A first task to try

Set RELAY_HOST=127.0.0.1, add one account, start the proxy, then send one short prompt from your agent and check which account answered.

Suggested exercise, not an installation test. We reviewed the linked documentation; no host compatibility is implied.
