Yes. Claudoscope is completely free and open-source under the MIT license.

Does Claudoscope work with Enterprise Claude Code?

Yes. Claudoscope reads directly from local JSONL session files in ~/.claude/projects/. It works with any Claude Code deployment including Enterprise API setups where cookie-based trackers cannot function.

How is Claudoscope different from the /usage command?

The /usage command shows a snapshot of your current session. Claudoscope gives you a full browsable history of every session, with search, cost breakdowns, and analytics across all your projects.

Does Claudoscope collect any data?

No. Claudoscope runs 100% locally on your Mac with zero telemetry. It reads session files from your local disk and never sends data anywhere.

Native macOS App

100% local. Zero telemetry. Your sessions never leave your disk.

Everything you need to understand your Claude Code sessions.

From real-time token tracking to deep configuration browsing, all running natively on your Mac.

Real-time Monitoring

Watches ~/.claude/projects/ via macOS FSEvents for near-instant file change detection. No polling, no Electron.

Cost & Session Analytics

Aggregates token usage across input, output, and cache, maps it to Anthropic or Vertex AI pricing, and visualizes your sessions, spending patterns, and usage over time.

Secret Detection & Config Health

19 lint rules check your CLAUDE.md files, skills, and hooks for issues. Secret detection scans sessions for leaked credentials with entropy-based filtering. Session checks flag runaway costs and token usage.

Configuration Viewer

Reads your settings.json and presents permissions, YOLO mode, memory, and custom slash commands in a browsable layout.

Fully Local & Private

No servers, no network requests, no analytics pings. Claudoscope reads your logs directly from disk. Nothing leaves your machine.

Skills & MCP Browser

Browse installed skills with full markdown rendering. Inspect MCP server arguments, commands, and environment variables.

Catch leaked secrets in your Claude Code sessions

Claudoscope continuously checks your configuration quality and watches for leaked credentials, all without leaving your machine.

Secret detection: Scans for private keys, AWS keys, API tokens, and more. Entropy filtering minimizes false positives.
Real-time alerts: Floating alert when a leaked credential is detected in an active session.
Config linting: 19 rules check your CLAUDE.md files, skills, and hooks for structural issues and invalid globs.
Health scores: Weighted config quality grade plus session checks for runaway costs, excessive tokens, and long conversations.
