Turn your local AI coding agent logs into a rich, interactive analytics dashboard — zero dependencies, fully offline, one command.

Live Demo →

You're burning tokens across multiple AI coding agents every day — but how much are you actually spending? Which model is the most cost-effective? When are you most productive? Are your caches saving you money?

Agent Usage Atlas reads your local log files (~/.codex/, ~/.claude/, ~/.cursor/), crunches the numbers, and generates a single self-contained HTML dashboard with 25+ interactive charts. No API keys, no cloud uploads, no dependencies beyond Python itself.

Pricing covers GPT-5.x, Claude 3/3.5/4.x (Haiku/Sonnet/Opus), and MiniMax-M2 out of the box.

• 25+ interactive ECharts visualizations — cost trends, token breakdowns, Sankey flows, chord diagrams, heatmaps, radar charts, calendar views, burn rate projections
• Multi-agent unified view — Claude Code + Codex CLI + Cursor in one dashboard, with per-source drill-down
• Cost analytics — per-model, per-day, per-session cost estimation with 30-day burn rate forecasting
• Tool call intelligence — ranking, frequency density, bigram sequences, command success rates
• Cache efficiency tracking — hit rate, savings estimation, cache vs. uncached token split
• Working pattern heatmap — hour × weekday activity distribution to find your flow states
• Session deep-dive — duration histogram, complexity scatter, median session cost
• Live dashboard mode — SSE-powered auto-refresh server with date range tabs (All / 7 days / Today)
• Bilingual narratives — auto-generated story summaries in both Chinese and English
• Animated data updates — stock-style green/red flash on number changes in live mode
• Single self-contained HTML — one file, works offline, shareable, archivable
• Zero dependencies — pure Python standard library, no npm/Node/Rust/Docker required
• Fully local — all data stays on your machine, nothing sent anywhere

Cost Analysis Daily cost trends, cost breakdown by token type, model cost ranking, Sankey flow	Token & Activity Daily token trends, source radar, narrative summary, rose chart
Heatmap & Sessions Activity heatmap, source radar, token calendar, session bubble	Tool Intelligence Tool ranking, bigram chord diagram, top commands, efficiency metrics

1. Parse — Reads JSONL log files and SQLite databases from each agent's local directory. Codex uses cumulative-delta token counting; Claude deduplicates by message ID; Cursor tracks activity counts.
2. Aggregate — Computes source rollups, daily rollups, session rollups, tool bigrams, chord diagram data, Sankey flows, burn rate projections, heatmaps, and narrative text.
3. Render — Injects the aggregated data into a self-contained HTML template with ECharts visualizations. In live mode, an SSE server pushes updates when log files change.

All data stays local — nothing is sent to any server.

1. Unified multi-agent dashboard — the only tool that tracks Claude Code + Codex CLI + Cursor simultaneously from local logs in a single view
2. Richest visualization suite — 25+ chart types including Sankey flows, chord diagrams, tool-call bigrams, heatmaps, burn rate projections, calendar views
3. True zero dependencies — Python stdlib only, no npm/Node/Rust/Docker/database required
4. Single self-contained HTML — one file, works offline, email it to yourself, archive it
5. Live SSE server — real-time auto-refresh with date range switching (All / 7 days / Today)
6. Cache efficiency analytics — unique among local tools, tracks savings and hit rates
7. Animated transitions — smooth number counter animations with stock-style green/red flash on live data refresh
8. Bilingual narrative — auto-generated story/summary in both Chinese and English
