See where your AI spend goes.

If CodeBurn shows you something your bill never did, star the repo so other developers find it, and consider sponsoring to keep 36 integrations honest.

Four surfaces, one source of truth: everything reads the session files already on your disk.

CodeBurn is a free, open-source, local-first tool that tracks AI coding token usage and cost across 36 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 36 AI tools.

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

Quick start · Find waste · Apply fixes · Guard · Compare models · Track what shipped · MCP · Supported tools · Commands · Features · How it reads data

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 pnpm dlx codeburn, or brew install codeburn on macOS.

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

codeburn menubar

On Linux, a GNOME Shell extension gives the same panel view; see Linux (GNOME).

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

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 lifetime                        # full history (uncapped)
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.

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.

codeburn optimize --apply             # review and apply fixes interactively
codeburn optimize --apply --dry-run   # print the plan, change nothing
codeburn optimize --apply --yes       # apply every appliable fix without prompting
codeburn act list                     # every change CodeBurn has made
codeburn act undo --last              # roll the most recent change back
codeburn act report                   # realized vs estimated savings

codeburn optimize finds the waste; --apply fixes the config-class findings for you: settings values, environment variables, archiving unused agents and skills. Every change is backed up and journaled before it lands. codeburn act list shows the history and codeburn act undo <id> restores the original files (it refuses if the files changed since being applied, unless you pass --force).

The loop closes on honesty: once an applied fix is at least 3 days old, codeburn act report compares its estimated savings against what your sessions actually did, and later codeburn optimize runs show that realized figure in the header. Estimates get checked against reality, not just claimed.

codeburn guard install            # hooks into this project's .claude/settings.json
codeburn guard install --global   # or into ~/.claude/settings.json
codeburn guard status             # caps, install locations, flagged projects
codeburn guard uninstall          # removes cleanly, leaves your own hooks alone

Guard installs opt-in hooks into Claude Code that watch session cost while you work:

• Soft cap (default $5): a one-time in-session warning when a session passes it.
• Hard cap (default $15): stops the session; codeburn guard allow lifts it for that session only.
• Checkpoint (default $3): if a session ends past this with no edits and no commits, a nudge suggests starting fresh with a named deliverable.
• Session openers: projects where optimize found waste get a one-line flag at session start.

Caps are edited in ~/.config/codeburn/guard.json (set a value to null to disable it). Add --statusline to show session cost in the Claude Code status line. Installs go through the same journal as everything else, so codeburn act undo removes them too. Hooks fail open: a broken guard never blocks a session.

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.

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

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/ambiguous spend as JSON

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

Attribution is timestamp-window based (heuristic): each commit is credited to at most one session, the tightest window containing it. The JSON report carries methodology: "timestamp-window".

Requires a git repository. Run from your project directory.

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. The usage graph follows the selected period with 15-minute, hourly, or daily buckets and can switch between per-session and per-model lines. Everything is read from disk on your machine and the server binds to localhost; nothing is uploaded.

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.

codeburn menubar

One command: downloads the latest .app, installs into ~/Applications, and launches it. Re-run with --force to reinstall. The 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.

Refresh cadence is set in Settings under Usage Refresh. Auto (the default) refreshes every 30 seconds on AC power and backs off on battery, in Low Power Mode, and while the display sleeps; fixed 1, 5, or 15 minute cadences and a Manual mode (refresh only when you open the popover or click Refresh Now) are also available. From Terminal:

defaults write org.agentseal.codeburn-menubar CodeBurnMenubarRefreshSeconds -int 300

Seconds between refreshes: 60, 300, or 900; 0 is Manual and -1 is Auto. Takes effect on the next refresh tick, no relaunch needed.

Preferred terminal decides where Full Report and Optimize open. Set it in Settings → General → Terminal, or from Terminal:

defaults write org.agentseal.codeburn-menubar CodeBurnPreferredTerminal -string iterm2

Allowed values are terminal (macOS Terminal.app, the default) and iterm2. Anything else falls back to terminal. Only terminals that can script a command into a live window are offered; if the chosen app is missing or fails to accept the command, CodeBurn tries Terminal.app and then runs the command in the background, logging each step to Console.app. Takes effect on the next launch of a command, no relaunch needed.

Linux gets the same ambient view through a GNOME Shell extension (GNOME 45+): spend in the top panel, period switcher, compact mode, and daily budget alerts. It lives in gnome/:

git clone https://github.com/getagentseal/codeburn && cd codeburn/gnome
./install.sh
gnome-extensions enable codeburn@codeburn.dev

See gnome/README.md for settings and development notes. On Windows, codeburn web is the always-on view for now.

claude mcp add codeburn -- npx -y codeburn mcp

codeburn mcp runs a local MCP server over stdio, so Claude Code, Cursor, or any MCP client can ask "where did my tokens go this week?" or "how do I spend less?" mid-conversation. It exposes two tools:

Everything is read from local disk, same as the CLI. Project names are pseudonymized by default; the agent only sees real names if it asks with include_project_names: true. For other MCP clients, configure a stdio server with command npx and args -y codeburn mcp.

CodeBurn auto-detects which AI tools you use. Each logo links to its provider doc.

LingTai TUI

If multiple providers have session data on disk, press p in the dashboard to toggle between them.

Each provider doc lists the exact data location, storage format, and known quirks. Linux and Windows paths are detected automatically. If a path has changed or is wrong, please open an issue.

The --provider flag filters any command to a single provider: codeburn report --provider claude, codeburn today --provider codex, codeburn export --provider cursor. Works on all commands: report, today, month, overview, status, export, web, optimize, compare, yield.

Adding a new provider is a single file. See src/providers/codex.ts for an example.
