Show HN: Claude Threads – Collaborate on Claude Code via Slack/Mattermost

[aschuth]

I wanted my team to start using Claude Code but didn't want to set everyone up. Started piping output to Mattermost (and later Slack) so people could watch.

Ended up building more: multiple sessions in parallel (each in a thread, hence the name), approve messages from other users with emojis, approve file writes, attach images/files, worktrees per thread.

It runs on your machine.

I built most of it using itself. Teammates watching live caught stuff I missed.
