claude-code-relay 0.0.8

Local proxy that exposes Claude CLI as an OpenAI-compatible API server

claude-code-relay

OpenAI-compatible API server that wraps your local Claude CLI.

Why?

Creating API keys is friction when you just want to experiment. You already pay for Claude Code subscription - use it.
