Show HN: Multiplayer Usage Tracking for Claude Code, Codex and OpenCode

Hey HN, I built this open source tool which lets you and your team track usage across Claude Code / Codex / OpenCode.

1. There's no hosting involved. Usage is stored and managed by https://useautumn.com/

2. You and your team members can spin up a local dashboard to view nice charts of your usage

3. You can backfill your historical usage if you wish to

I built this because we often run ccusage (which is an amazing tool) to check how much AI spend each of us in our team have accumulated, and have fun comparing it. With this tool, everything is centralized, you can group by / filter models / harnesses, and compare & track usage between different members in a unified way.

tldr, it's a fun way to compare usage of these agents between your team, and can be set up in <5 minutes. Have fun with it!
