AI product Open source
CodeBurn is a free, open-source, local-first tool by AgentSeal that reads session files written by AI coding tools and reports token usage and estimated cost by provider, model, project, task, and activity. It provides a terminal dashboard and reports, a localhost web dashboard, desktop and tray or menubar views, exports, model comparisons, subscription-plan tracking, and optional cross-device aggregation.
Its deterministic analyzers classify work into task categories from tool usage and message keywords, calculate token costs using LiteLLM pricing cached locally, and scan coding-agent sessions for patterns such as repeated file reads, low read-to-edit ratios, uncapped shell output, unused MCP servers, bloated configuration, and retry-heavy work. The optimize command produces estimated savings and fixes; applicable configuration changes are backed up and journaled so they can be undone and later compared with observed usage. The yield command heuristically correlates sessions with Git commits to classify spend as productive, reverted, abandoned, or ambiguous.
The guard feature installs opt-in Claude Code hooks for soft and hard session-spending caps, checkpoints, and status-line reporting. CodeBurn also exposes local usage and savings through an MCP server over stdio. The CLI reads data from the local machine without wrappers, proxies, API keys, or uploads; the optional desktop applications can send anonymous bucketed telemetry after consent. It requires Node.js 22.13 or newer, and the repository is licensed under MIT.
