Self-hosted orchestrator for coding agents like Claude Code, Codex, and Cursor, controlled from phone, desktop, web, or CLI.

Paseo runs coding agents on your own machines and lets you drive them from your phone, desktop, web, or terminal. It’s for developers who use CLI agents like Claude Code or Codex and want to start, monitor, and steer them without sitting at their laptop. Kick off a task at your desk. Check on it from your phone later.
It sits on top of the agents you already have rather than replacing them. Each provider runs as its own process using its native harness, so your subscriptions, skills, config, and MCP servers keep working, and Paseo doesn’t wrap or modify their behavior.
An optional self-hosted Hub adds GitHub, Slack, and Discord triggers, so mentioning a bot can start an agent on your own daemon with your own keys. It’s free.
