CodeBurn is a free, open-source, local-first tool that tracks AI coding token usage and cost across 31 tools and agents (Claude Code, Cursor, Codex, Gemini, Grok and more), broken down by model, project, and task.

You pay for Claude, Codex, Cursor, and a stack of other AI tools. The bill tells you the total. It never tells you that half of it went to conversation instead of code, or that an expensive model burned your budget on work a cheaper one would have one-shot.

CodeBurn does. It reads the session files your tools already write to disk and breaks down every token and dollar by task, model, tool, and project, across 31 AI tools.

Everything runs locally. No wrapper, no proxy, no API keys, nothing leaves your machine. Pricing comes from LiteLLM, refreshed daily.

A week across every tool you use, in one screen.

Quick start

Run it instantly, no install needed:

npx codeburn

That opens the interactive dashboard (last 7 days by default). Arrow keys switch periods, q quits. That is the 30-second version. You now know where your AI budget goes.

Install it for a permanent codeburn command:

npm install -g codeburn

Also runs via bunx codeburn or dx codeburn, or brew install codeburn on macOS.

Menu bar app for macOS, with your spend always in the menu bar:

codeburn menubar

Requires Node.js 22.13+ and at least one supported tool with session data on disk. For Cursor and OpenCode, better-sqlite3 installs automatically.

Your month at a glance

codeburn overview                                    # this month, clean tables
codeburn overview --no-color                         # plain text, ready to paste
codeburn overview --from 2026-06-01 --to 2026-06-15  # any date range
codeburn overview -p all                             # all time
codeburn overview --provider claude                  # one tool only

codeburn overview prints a copy-pasteable summary of where your AI spend went: totals (cost, tokens, cache hit), a breakdown by tool and by top model, your highest-value days, top projects, a per-day table, and activity and tool usage. Pipe it anywhere (into pbcopy, a PR, Slack, or a tweet); color drops automatically when the output is not a terminal, or pass --no-color.

Find and fix waste

codeburn optimize                       # scan the last 30 days
codeburn optimize -p today              # today only
codeburn optimize -p week               # last 7 days
codeburn optimize --provider claude     # restrict to one provider
codeburn optimize --format json         # setup health + findings as JSON

codeburn optimize scans your sessions and your ~/.claude/ setup for waste patterns:

• Files Claude re-reads across sessions (same content, same context, over and over)
• Low Read:Edit ratio (editing without reading leads to retries and wasted tokens)
• Wasted bash output (uncapped BASH_MAX_OUTPUT_LENGTH, trailing noise)
• Unused MCP servers still paying their tool-schema overhead every session
• Ghost agents, skills, and slash commands defined in ~/.claude/ but never invoked
• Bloated CLAUDE.md files (with @-import expansion counted)
• Cache creation overhead and junk directory reads
• Context-heavy sessions where effective input/cache tokens swamp output
• Possibly low-worth expensive sessions with no edit turns or repeated retries when no git/gh delivery command is observed

Each finding shows the estimated token and dollar savings plus a ready-to-paste fix: a CLAUDE.md line, an environment variable, or a mv command to archive unused items. Findings are ranked by urgency (impact weighted against observed waste) and rolled up into an A to F setup health grade. Repeat runs classify each finding as new, improving, or resolved against a 48-hour recent window.

You can also open it inline from the dashboard: press o when a finding count appears in the status bar, b to return.

Compare models

codeburn compare                        # interactive model picker (default: last 6 months)
codeburn compare -p week                # last 7 days
codeburn compare -p today               # today only
codeburn compare --provider claude      # Claude Code sessions only

Which model is actually better for your work? Press c in the dashboard, or run codeburn compare. Arrow keys switch periods, b to return.

Section	Metric	What it measures
Performance	One-shot rate	Edits that succeed without retries
Performance	Retry rate	Average retries per edit turn
Performance	Self-correction	Turns where the model corrected its own mistake
Efficiency	Cost per call	Average cost per API call
Efficiency	Cost per edit	Average cost per edit turn
Efficiency	Output tokens per call	Average output tokens per call
Efficiency	Cache hit rate	Proportion of input from cache

Also compares per-category one-shot rates, delegation rate, planning rate, average tools per turn, and fast mode usage.

Track what shipped

codeburn yield                  # last 7 days (default)
codeburn yield -p today         # today only
codeburn yield -p 30days        # last 30 days
codeburn yield -p month         # this calendar month
codeburn yield --format json    # productive/reverted/abandoned spend as JSON

Did the spend actually ship? codeburn yield correlates AI sessions with git commits by timestamp:

Category	Meaning
Productive	Commits from this session landed in main
Reverted	Commits were later reverted
Abandoned	No commits near session, or commits never merged

Requires a git repository. Run from your project directory.

Browser dashboard

codeburn web                    # opens http://localhost:4747 in your browser
codeburn web -p 30days          # start on a different period
codeburn web --port 8080        # pick a port (falls back to a free one if taken)
codeburn web --no-open          # start the server without opening a browser

A local web dashboard with the same task, model, tool, and project breakdowns as the TUI, rendered with charts. Everything is read from disk on your machine and the server binds to localhost; nothing is uploaded.

Combine usage across your devices

See one total across your laptop, desktop, and work machine on the same network. On each other device, share its usage:

codeburn share --pair           # opens a pairing window and prints a PIN

Then add it once from your main device (the PIN authorizes the pairing):

codeburn devices add            # find nearby devices and pair, or: add <host> --pin <pin>
codeburn devices                # combined totals by machine
codeburn devices rm <name>      # forget a device

Pairing is PIN-authorized and stays on your local network. You can also discover and pair devices straight from the browser dashboard.

Menu bar

codeburn menubar

One command: downloads the latest .app, installs into ~/Applications, and launches it. Re-run with --force to reinstall. Native Swift and SwiftUI app lives in mac/ (see mac/README.md for build details).

The menubar icon shows the spend period selected in Settings (Today by default; Week, Month, and 6 Months are also available). Non-today periods add a short suffix such as $42 / mo so the menu bar value stays clear. Click to open a popover with agent tabs, period switcher (Today, 7 Days, 30 Days, Month, All), Trend, Forecast, Pulse, Stats, and Plan insights, activity and model breakdowns, optimize findings, and CSV/JSON export. Refreshes every 30 seconds.

You can also set the menubar status period from Terminal:

defaults write org.agentseal.codeburn-menubar CodeBurnMenubarPeriod -string month

Allowed values are today, week, month, and sixMonths. Relaunch the app to apply external defaults changes.

Compact mode shrinks the menubar item to fit the text, dropping decimals (e.g. $110 instead of $110.20):

defaults write org.agentseal.codeburn-menubar CodeBurnMenubarCompact -bool true

Relaunch the app to apply. To revert: defaults delete org.agentseal.codeburn-menubar CodeBurnMenubarCompact.
