What is this?
Mixdog is an open-source desktop coding agent that matches OpenAI's Codex on the Terminal-Bench 2.1 benchmark while using 63% fewer tokens. It bundles an editor, terminals, Git/GitHub integration, and multi-model orchestration into one app.

The headless 'mixdog exec' mode also skips personal memory, prior sessions, skills, MCP servers, and plugins, and is not a network-isolated sandbox.
