Quick answer
CodeBurn is an open-source cost tool that splits AI coding spend by task and branch and can stop runs with a spend guard. UsageAtlas is an open-source dashboard for live limits, alerts, and long history across 14 tools. Pick CodeBurn to cut cost, UsageAtlas to watch limits, or run both.

Questions, answered
Is CodeBurn free?
Yes. CodeBurn is free and open source.
Does UsageAtlas break cost down by git branch?
No. It groups usage by project folder, session, model, and tool.
Can either tool stop Claude Code at a budget?
CodeBurn's spend guard uses Claude Code hooks to do that. UsageAtlas sends an alert but never stops a run.
