doxray

X-ray for your Claude Code sessions. Open a readable report — conversation, tokens, estimated cost and tool usage — straight from your .jsonl session files. Everything is parsed locally: your data never leaves your machine.

Two ways to use it

1. Web (no install)

Go to doxray.app and drag a session file (~/.claude/projects/<project>/*.jsonl) onto the page.

2. CLI

Run it inside any project you've used with Claude Code:

npx doxray-app

(Install it globally with npm i -g doxray-app and the command becomes just doxray.)

It finds that project's sessions, lets you pick one, and opens the report in your browser (served locally on 127.0.0.1, nothing uploaded).

doxray            # interactive list of the project's sessions
doxray --latest   # open the most recent session
doxray <id|n>     # open a specific session (by id or list number)

Requires Node 18+.

How it finds your sessions

Claude Code stores sessions under ~/.claude/projects/<slug>/, where <slug> is the working directory with non-alphanumeric characters replaced by -. doxray derives the slug from your current directory and reads the matching folder.

"Estimated cost"

On a flat-rate Pro/Max plan you never see what a session is worth. doxray multiplies the tokens in your log by Anthropic's public API list prices to estimate it. It's a reference figure, not a bill.

Development

npm install
npm run dev      # hot-reload dev server
npm run build    # production build into dist/

The CLI (bin/doxray.mjs) serves the built dist/ plus the chosen session over a tiny local server, then opens the browser at /?local=1 (the app auto-loads the session).

Privacy

100% local. The web app reads files with the browser File API; the CLI serves them from 127.0.0.1. No uploads, no account.
