Endo

Endo is an AI desktop application that composes multiple vendor agents into a single chat interface and workflow system.

Endo functions as a higher-order harness that takes AI agents as building blocks and composes them freely. It drives Codex, Claude Code, and Antigravity natively through their respective CLIs using existing subscriptions without requiring API keys. Users can switch between models mid-thread while maintaining full conversation history, fan work out across sessions, and schedule recurring tasks. Workflows are defined as TypeScript files in the workspace using functions like agent, parallel, and phase. The application persists all sessions, runs, and focused branch conversations locally on the machine.
