OpenBurnBar reads what your agents already leave behind on disk and turns it into a coherent picture: today's burn, this week's pattern, this month's budget, every session you ran, every quota window you're about to hit.
Your Claude Code · 5h window hits 80% at the current rate by 3:47pm. Top draw is opus-4-7 on the ledger-rebuild project.
Numbers come from the vendor's own API or local logs. Confidence is labeled on every row.
OpenBurnBar reads the JSONL crumbs Claude Code, Codex, Factory and friends drop on disk. Your API keys never leave the providers you already trust.
Real numbers. Cost is exact where the vendor returns it, computed where they don't. Confidence is labeled on every row.
Five-hour windows for Claude Code and Codex. Weekly for Kimi. Premium interactions for Copilot. Per-model for MiniMax. Plan-used USD for Cursor. Refresh on tap.
InsightEngine notices when spend spikes, a new model shows up, a cache lands, or a quota window is about to close. Daily digest at the time you choose.
Two runtimes share one identity. Stateless per-turn against a CLI subprocess for quick answers, or multi-turn against a local Hermes Gateway for deeper sessions — both grounded in your own OpenBurnBar SQLite.
An on-device assistant that knows your sessions, providers, models, and recent runs. Two modes — Local Index (stateless, CLI-backed) and Hermes Gateway (multi-turn, OpenAI-shaped, runs locally).
Every entity Hermes mentions — cost, session, provider, model, window, tool, project — becomes a tappable inline chip that opens the matching native detail view.
Hermes streams JSON envelopes that render to 10 native Swift Charts kinds and sandboxed Mermaid diagrams on iOS and iPadOS.
The daemon owns provider routing, quota refresh, retrieval, projects, missions, and a JSONL run journal you can replay. The CLI scripts it. Every other surface speaks to it.
A launchd-managed local daemon owns routing, quota, retrieval, projects, missions, and replay. Every surface — Mac, iOS, Cursor, CLI — talks to it.
health · controller · questions · followups · missions · mission-approve · simulator-runs · simulator-replay. Scriptable from any agent, git hook, or operator console.
The home base. Lives in the menu bar, reads local agent logs, surfaces cost, tokens, quota, sessions, and insights.
Quota Watch, Pulse, Streams, Hermes, Chart Studio. The Mac runs the data; the phone/tablet renders it natively.
An activity-bar panel that hooks into the daemon over the local UNIX socket. Build locally and load unpacked — no marketplace listing yet.
The control plane. A launchd-managed UNIX socket service every surface talks to.
openburnbar — eight commands for scripting, agents, and operators. Same daemon, no extra account.
Lock-screen quota, Dynamic Island countdown, home-screen cost sparkline. Siri shortcut: "What's my burn today?"
One-click "Make display work" — casts a live OpenBurnBar dashboard, with proof of acceptance before marking healthy.
Read-only Firestore consumer — renders burn data other clients push to Firebase. Source under android/.
A clean console is built on what you choose to leave out as much as what you choose to put in.
Every provider row carries one of three labels — Exact, Estimated, Unavailable. We don't pretend to know what the vendor doesn't tell us.
Local SQLite + the local daemon are canonical. Firestore is an optional replication plane — never the source of truth. The whole product works offline.
OpenBurnBar is MIT-licensed. The README, the architecture doc, the threat model, the provider matrix, the changelog — all in the open.
