Disclosure: I built Tandem and it is fully open source. Just as I said it: you can run Claude Code through Claude.ai or ChatGPT through the browser, and it opens up a Claude Code session on your computer and can manage it. What it does: you work in Claude.ai chat like normal while you brainstorm or write a spec. When done, it can run a Claude Code session or resume a Claude Code session on your machine, so now you can let Claude.ai manage Claude Code instead of you. The new part is that Claude Code responds back into your Claude.ai browser chat by itself, and Claude.ai answers that response back down through the CLI. So it runs as a loop on its own. That means you don’t copy-paste, and you don’t have to step away from your brainstorming tool to go verify or do the work. Technical breakdown: Tandem runs a local MCP bridge that connects a browser chat to real interactive Claude Code sessions in tmux. It is not a hosted agent service and it is not just headless claude -p orchestration. The useful pieces are session open/resume, incremental reads, live attach, completion events, and a manager/worker relay for longer work. The security model is explicit because it runs real commands locally: the token acts like a password, the public tunnel is user-owned, and the cwd allowlist is the main blast-radius control.
