Claude Simple Stats Bar (VS Code)

Live Claude Code session stats — model, tokens, context left, cost — in the VS Code status bar.

Features

• A status bar segment shows your model, total tokens, context used, and estimated cost. It updates live as you chat.
• Hover the segment for a full token breakdown and the transcript path.
• Click the segment for a session panel listing every session in the workspace, a 7-day spend chart, and spend by model.
• Pricing and poll interval are both configurable.

Requirements

• VS Code 1.90 or newer.
• The Claude Code CLI, writing transcripts locally under ~/.claude/projects/. This extension has no other data source.

Claude segment

• Model — the active model name, led by a dashboard icon.
• Total tokens — input + output + cache for the whole session.
• Context used — the icon/tag/bar from Features above, based on the last turn only, not a running total. Answers "will my next message fit," not "how much have I used overall."
• Estimated cost — built-in pricing for the current Sonnet/Opus/Haiku/Fable lineup; override via claudeSimpleStatsBar.pricing (see Cost estimates).

Hover the segment for a per-category token breakdown and the transcript path:

Session panel

Click the segment, or run Claude Simple Stats Bar: Open Session Panel:

1. Sessions in this workspace — every transcript found here, with the primary one marked. Each row shows a timestamp to tell sessions apart: last active <time> for a still-running session, or a scaled ended <time> for one that's finished. Only the 6 most recent show by default — click Show more sessions to reveal the rest. Running more than one session at once? Use Make primary, or the Switch Primary Session command, to pick a different one — the pick persists across VS Code restarts.
2. Last 7 days — a spend chart and per-model breakdown, stored locally and pruned past 7 days.
3. Compaction — a heuristic count of likely compaction events.

Where the data comes from

There's no public API for Claude Code session telemetry. This extension reads the same .jsonl transcript files Claude Code already writes to disk, under ~/.claude/projects/<workspace-path-with-slashes-replaced-by-dashes>/<session-id>.jsonl. It scans every folder in a (possibly multi-root) workspace for a matching directory and picks the most recently modified file as primary, re-parsing it on file changes plus a periodic poll as a fallback.

Cost estimates

Built-in USD rates ship for the current Sonnet/Opus/Haiku/Fable lineup (as of 2026-08), so cost shows without any setup. Anthropic's pricing changes over time — verify current rates before relying on this for anything beyond a rough estimate. Override a model's rate, or add one that isn't built in, via claudeSimpleStatsBar.pricing:

{
  "claudeSimpleStatsBar.pricing": {
    "claude-sonnet-5": {
      "inputPerMillion": 3,
      "outputPerMillion": 15,
      "cacheWritePerMillion": 3.75,
      "cacheReadPerMillion": 0.3
    }
  }
}

Models with neither a built-in default nor a configured entry show cost as n/a.

Install

Search for Claude Simple Stats Bar in the VS Code Extensions view, or install from the Marketplace listing.

Or build it from source:

git clone https://github.com/rcanpahali/claude-simple-stats-bar.git
cd claude-simple-stats-bar
npm install
npm run package
code --install-extension claude-simple-stats-bar-*.vsix

Then reload the window (Cmd+Shift+P → "Developer: Reload Window"). After code changes, run npm run package again (it removes the old .vsix before rebuilding) followed by the install command.

Or press F5 from a clone to compile and open an Extension Development Host window with it loaded, without installing anything.
