Open source · Share your sessions
Turn agent sessions into shareable threads.
Take a Claude Code or Codex session from your machine and publish it as a web page. Tool calls, diffs, metadata, and cost all stay intact.
Install
Add ThreadCast to your agent.
Install the Claude Code plugin directly from this repo, or add the Codex marketplace and install ThreadCast from `/plugins`.
Use it
Share from inside your agent.
Log in once, check what ThreadCast can see locally, then share the latest session or pick one from this project folder.
