Claude Code in Threadlines

A desktop GUI for Claude Code

Threadlines runs Anthropic's Claude Code with your own sign-in, so your Claude plan, MCP servers and skills come along. Add Codex to the same thread whenever you want a second opinion.

Questions

Does Threadlines use my Claude subscription?

Yes. It runs Anthropic's Claude Code with your sign-in, the same way a terminal does. If you set an Anthropic API key in your environment, Claude Code bills that key instead, and Threadlines warns you when that happens.

Can I use Claude Code and Codex together?

Yes. Add Codex to a Claude thread and ask it to review Claude's work, or switch the thread to Codex and it gets a recap plus your working tree.

Does my code go anywhere new?

No. Your prompts and code go to Anthropic exactly as they do from the terminal. Threadlines runs on your computer and doesn't upload your code to a server of its own.

What does it cost?

Threadlines is free and MIT-licensed. You pay Anthropic for your Claude plan, or for API usage if you use a key.
