Contop is an open-source remote compute agent for controlling a desktop from a phone. It streams the screen in real time, accepts voice or text input, and can carry out tasks autonomously. The agent can run terminal commands, interact with the desktop and Chrome, and read, edit, or search files; the maker lists 33 built-in tools for commands, screen control, file management, and workflow automation. Users can create reusable skills using prompt instructions, YAML workflows, Python tools, or combinations. Listed AI providers are Google Gemini, OpenAI, Anthropic, and OpenRouter, with per-role model selection. Connections include LAN, Tailscale, and Cloudflare Tunnel, with automatic path selection and fallback. The site says phone-to-desktop traffic is end-to-end encrypted with DTLS and does not pass through third-party servers. Risky commands can be blocked, sandboxed, or held for approval, and session logs record prompts, commands, tools, and results. Android is available via Google Play; iOS is coming soon. Desktop downloads for Windows, macOS, and Linux require Python 3.12 or later.
