Claudoscope: Free Open-Source macOS App for Browsing Claude Code Sessions and Tracking Costs
Product Hunt·medium signal
Claudoscope is a free, open-source macOS menu bar app that provides full browsable history of every Claude Code session with search, cost breakdowns, and analytics across projects. It aggregates token usage across input, output, and cache, maps it to Anthropic or Vertex AI pricing, and auto-detects leaked API keys and credentials in sessions. Runs 100% locally with zero telemetry under MIT license.
