CodeBurn Files

What's New

Highlights since v0.9.11:

Added (CLI)

• MCP server — codeburn mcp exposes get_usage and get_savings to AI agents over stdio, with project names pseudonymized by default. (#429)
• New providers: Devin (#444), Antigravity IDE (#418), JetBrains — IntelliJ/DataGrip via Copilot (#433), coder/mux (#438), and an opt-in Vercel AI Gateway datasource (#432).
• Automatic pricing gap-fill from models.dev and OpenRouter for models LiteLLM hasn't indexed yet (e.g. Claude Fable 5). (#457)
• Proxy-aware cost attribution — codeburn proxy-path reports subscription-backed spend (e.g. Claude Code over Copilot) as net out-of-pocket, leaving actual cost untouched. (#417, [#459])
• Local-model savings — codeburn model-savings reports the counterfactual spend vs a paid baseline; the local call still costs $0. (#421)
• CNY currency (#430) and a contribution heatmap insight (#437).

Fixed (CLI)

• Per-file parse isolation — one malformed session file no longer aborts the run or empties the daily-history trend. (#441, [#450], [#453])
• Codex fork dedupe undercounting (#458) and cache-read double-counting in the models report (#447).
• Model-name matching on the version boundary so claude-opus-4-6 and claude-opus-4-8 don't collapse. (#417)
• Critical-path fetch timeouts so a stalled network can't wedge the CLI or menubar. (#445, [#448])
• Vercel AI Gateway data now flows through aggregation instead of reporting $0; Fable 5 and Mythos 5 price correctly. (#432, [#466])

Fixed (macOS menubar)

• Refresh reliability — awaits the CLI exit via its termination handler and caps concurrent spawns, fixing the "Loading…" wedge after a long idle. (#462)
• Recover from stuck loading orphaned across sleep/wake (#412); correct currency picker (#435).

The macOS menubar app is published separately as mac-v0.9.12.
