Magpie

Magpie is a desktop app that lets coding agents use models from any vendor. A user adds a provider once, such as DeepSeek, Kimi, GLM, Qwen, OpenRouter or Ollama, or signs in with an existing Claude or ChatGPT plan, and then picks that model from agents like Codex, Claude Code, Gemini CLI, OpenCode, Goose or Cursor CLI with one click. It works through a gateway that runs on the user's own machine and translates between the OpenAI Chat and Responses formats, the Anthropic Messages format and the Google Gemini format, including streaming, tool calls and reasoning. A menu bar view shows which model each agent runs. Choosing a new value rewrites only that key in the agent's configuration, and choosing the native model restores what was there before. Saved profiles switch every agent at once. Subscriptions can be shared across agents, so a Claude Code sign in can power OpenCode or a Copilot seat can serve any agent. Smart routing sends each turn to a model according to intents the user describes in a few words, using a small classifier model, and falls back to other keys or accounts when one runs out. Magpie is free and open source. The site lists macOS 12 and later as the supported platform for the app download, and also offers a terminal install. No paid plans are published.
