One proxy. Every AI coding tool.

Route your GitHub Copilot subscription through standard OpenAI and Anthropic APIs. Works with Claude Code, Codex CLI, and anything that speaks OpenAI.

Your tool → github-router → GitHub Copilot API

Terminal

$ npx github-router@latest start click to copy

Pick your tool

Authenticate once, then connect your favorite AI coding tool.

Claude Code

Interactive setup copies a launch command to your clipboard:


npx github-router@latest start --claude-code

Or drop this in .claude/settings.json:

Codex CLI

One flag or two env vars:


npx github-router@latest start --codex


export OPENAI_BASE_URL=http://localhost:8787/v1
export OPENAI_API_KEY=dummy
codex -m gpt5.2-codex

Any OpenAI Client

Point any tool at localhost:8787/v1:


curl http://localhost:8787/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4.1","messages":[{"role":"user","content":"Hello"}]}'

API Endpoints

OpenAI and Anthropic formats, streamed or buffered. OpenAI endpoints are also available without the /v1 prefix; Anthropic uses /v1/messages only.

`/v1/chat/completions`	POST	OpenAI Chat Completions
`/v1/responses`	POST	OpenAI Responses (Codex models)

`/v1/models`	GET	OpenAI model list
`/v1/embeddings`	POST	OpenAI embeddings
`/v1/search`	POST	Web search
