Claudoscope
macOS menu bar app to browse, search, and cost every Claude Code session

3-1The Panel's Take
Claudoscope is a free, open-source macOS menu bar app that gives Claude Code users a full session history browser, cost analytics, and search across all their coding sessions. It reads directly from local JSONL session files in ~/.claude/projects/ and works entirely offline — no telemetry, no data sent anywhere, fully MIT-licensed. The tool estimates costs from raw token counts against published API pricing, giving developers a clear picture of where their Claude Code spend is going across projects and sessions. It also automatically scans for leaked API keys and credentials in session content — effectively adding a passive security audit to every session review. Claudoscope fills a real gap: Claude Code's built-in /cost command only covers the current session. Claudoscope gives historical visibility and project-level analytics. It works with any Claude Code deployment including Enterprise API setups where cookie-based session trackers fail. Built and maintained by an indie developer, free forever.

“As someone who runs Claude Code 8+ hours a day, this is immediately valuable. I had no idea which projects were burning through tokens until I installed it. The leaked credential detection is a bonus I didn't expect — it already caught a test API key I'd forgotten to rotate.”
“This is fundamentally a log file reader with cost estimation math. Anthropic could ship this natively in Claude Code in a single PR and make Claudoscope obsolete overnight. The gap it fills is real, but the risk of deprecation-by-inclusion is very high for an indie-maintained tool.”
“The emergence of cost-tracking tools for AI coding sessions is a leading indicator of developer maturity. When developers start optimizing their AI spend like they optimize their AWS bill, we've crossed a real threshold. Claudoscope is primitive, but it's the first version of what becomes a full AI development economics dashboard.”
“Indie developers and freelancers who need to track Claude Code costs against client projects will love this. The project-level breakdown finally makes AI tool costs legible as a line item on a client invoice — something that's been surprisingly hard to do until now.”
