A stack trace for your agent history. staxtrace ingests session logs from twenty coding-agent providers into one local SQLite store, then builds four things on top: cost analytics, time-travel playback with step-by-step filesystem reconstruction, a memory layer your agents query mid-task, and an offline chat over your own history.
Local-first from the first commit. No account, no telemetry, nothing leaves

An agent with no record of what it did last time is not an engineer. It is a very fast intern on its first day, every day.
