Why Claudon?

Claude Code is fast until it isn't. Which turn burned ten minutes? Was it the model, a slow tool, or you being away? Did that failing tool call loop? What did the session really cost? Your answers are already in ~/.claude; Claudon reads them and shows you:

• Where time went: model vs. tools vs. permission waits vs. idle, per task, turn and subagent.
• What it cost: token usage × list prices per model generation (override with --pricing).
• What went wrong: automatic detection of tool failures, slow turns and retry loops.
• How hard it thought: thinking time vs. thinking tokens.
• Safe to share: --redact strips prompts, paths, commands and project names.

It is a single Python file using only the standard library. No telemetry, no network, no account.

🚀 Quick Start

Use whichever runner you already have; each downloads and runs the latest release on demand:

claudon ~/.claude -o report.html --open      # after a global install

The npm-family packages (npx, pnpm, yarn, bun) are a thin launcher around the same Python script, so they need Python 3.11+ on your PATH (python3, python or py). No Python at all? Use the browser version or a standalone binary from GitHub Releases. Use @beta / uvx --prerelease allow for pre-releases.

Standalone Shell Script

curl -fsSL https://raw.githubusercontent.com/infenia/claudon/main/install.sh | sh

# recommended: pin a release (see GitHub Releases); claudon.py is checked against that release's SHA256SUMS
curl -fsSL https://raw.githubusercontent.com/infenia/claudon/main/install.sh | CLAUDON_VERSION=vX.Y.Z sh

The checksum catches corrupted or mismatched downloads. To also prove a release file was built by this repo's workflow, download it and run gh attestation verify claudon.py -R infenia/claudon.

Direct Clone

git clone https://github.com/infenia/claudon.git
cd claudon
python3 claudon.py ~/.claude -o report.html --open

⚡ WebAssembly (In-Browser / Zero Python)

Run Claudon entirely in your browser without local Python installed. The page loads ../claudon.py, so it has to be served over HTTP (opening the file directly via file:// can't load it):

1. From the repository root run python3 -m http.server (or host the repo on any static server, e.g. GitHub Pages).
2. Open http://localhost:8000/wasm/.
3. Drop .jsonl transcripts, or use Open Folder on ~/.claude/projects to keep project grouping and subagents.

Nothing is uploaded. Files are read by the browser and analyzed on your machine; the page's only network requests download the Pyodide runtime (jsDelivr) and claudon.py, and once it shows Ready it keeps working offline. Chrome and Edge ask to let the page view the folder. Browsers without that folder API (Firefox, Safari) show their own "upload" prompt for folder pickers, which only grants the page read access.

🛠️ Native Binary (Nuitka)

To compile Claudon into a single native binary locally:

pip install nuitka==4.2.2 zstandard
python scripts/build_nuitka.py --onefile

Standalone executables are output to dist/.

📦 Releases

Claudon follows Semantic Versioning and is released through an automated, reviewable pipeline: Conventional Commit PR titles drive an auto-generated release PR (version bump + CHANGELOG); merging it tags the release and publishes:

• Nuitka Binaries: Linux x86_64, macOS (arm64 and Intel) and Windows, attached to GitHub Releases with SHA256SUMS and build provenance attestations (gh attestation verify <file> -R infenia/claudon).
• PyPI: uvx, pipx or pip (trusted publishing).
• npm: npx, pnpm dlx, yarn dlx or bunx (with provenance).

Want pre-release builds? uvx --prerelease allow claudon or npx claudon@beta. Full process: docs/RELEASING.md.

⚡ Integration with Claude Code

Install Claudon as a native slash command inside Claude Code:

claudon --install-plugin

Once installed, simply type /claudon in any active Claude Code CLI session to instantly generate and open your analytics dashboard!

⚙️ Options & CLI Usage

claudon [PATH] [-o FILE] [--redact] [--pricing FILE] [--open] [--install-plugin [--force]] [--version]

PATH can be a ~/.claude directory, its projects/ subfolder, a specific project directory, or a single .jsonl transcript file (default: $CLAUDE_CONFIG_DIR if set, else ~/.claude).

📊 What's in the Report?

• Task Breakdown: each human prompt through to completion.
• Turns & Subagents: model API calls vs. agent delegation.
• Time, Thinking & Cost: the breakdowns described above.
• Bottlenecks: failures, slow turns and loops, surfaced automatically.

The report is one self-contained .html file: no server, no external assets, easy to attach to an issue (use --redact).
