Control your PC's OpenCode — the terminal AI coding agent — from your phone, from anywhere in the world. Free, open source, and private: your code never touches CrossCode's servers, because there are none.
Open a terminal in your project directory and run:
npx crosscodeThis starts opencode serve, opens a tunnel, and prints a QR code in your terminal. (Make sure OpenCode is installed first.)
- Install the CrossCode app — Android (iOS coming soon)
- Open the app and scan the QR code
- Start chatting with your agent
That's it. No account, no configuration, no shared network.
Your phone connects to the OpenCode instance running on your machine through a secure tunnel, and streams everything back in real time — prompts, streaming responses, tool-call approvals, and file diffs.
- CLI Reference — all commands, flags, and configuration
- Development — set up and build the project locally
- Features — what CrossCode can do
- Tunnel Server — self-hosted relay for paid users
