⚠️ Did you know? Claude Code deletes your session data after 30 days by default. Once deleted, your token usage and cost history are gone forever — unless you preserve them.
Track token usage and costs across all your AI coding CLIs — Claude Code, Codex CLI, Gemini CLI, and OpenCode — in one dashboard.
provided also PI Agent since April 2026
Built with Rust for ultra-fast performance (simd-json + rayon parallel processing).
Why toktrack?
| Problem | Solution |
|---------|----------|
| 🐌 Existing tools are slow — 40+ seconds on large datasets | ⚡ 1000x faster — cached queries in ~0.04s |
| 🗑️ Claude Code deletes data after 30 days — your cost history disappears | 💾 Persistent cache — history survives even after CLI deletes files |
| 📊 No unified view — each CLI has separate data | 🎯 One dashboard — Claude Code, Codex CLI, Gemini CLI in one place |
Performance Comparison
Dataset: 2,000+ JSONL files, 3.4 GB total
Existing tools: ████████████████████████████████████████ 40s+
toktrack (cold): █ ~1s (first run)
toktrack (cached): ▏ ~0.04s (daily use)
└── up to 1000x faster
The Problem: You've been using Claude Code for 3 months, spending hundreds of dollars. One day you want to check your total spending — but Claude Code already deleted your session files from 2 months ago. That cost data is gone forever.
toktrack solves this. It caches daily cost summaries independently, so your usage history survives even after the CLI deletes the original files.
Past dates in each *_daily.json are immutable — once a day is summarized, the cached result is never modified. Only the current day is recomputed on each run. This means even if Claude Code deletes session files after 30 days, your cost history remains intact in the cache.
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
A Claude Code plugin that automatically captures everything Claude does during your coding sessions, compresses it with AI (using Claude's agent-sdk), and injects relevant context back into future sessions.
