⚠️ 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.

The token & cost tracker that never loses your history. Most tools re-read your CLI's session files on every run — so when Claude Code deletes them after 30 days, your cost history goes with them. toktrack keeps a persistent cache, so your history survives.

Track usage across all your AI coding CLIs — Claude Code, Codex CLI, Gemini CLI, Qwen Code, OpenCode, and PI Agent — in one dashboard. Built in Rust, so it stays fast even on huge histories (simd-json + rayon).

toktrack overview

Why toktrack?

Problem	Solution
🗑️ Claude Code deletes data after 30 days — your cost history disappears	💾 Persistent cache — history survives even after the CLI deletes its files
📊 No unified view — each CLI keeps its own separate data	🎯 One dashboard — Claude Code, Codex, Gemini, Qwen, OpenCode, PI Agent in one place
🐌 Re-scanning big histories is slow	⚡ Cached queries in ~0.04s — instant on every run

Features

Data Preservation — Persistent cache keeps your cost history even after a CLI deletes its own session files
Multi-CLI Support — Claude Code, Codex CLI, Gemini CLI, Qwen Code, OpenCode, PI Agent in one place
TUI Dashboard — 3 tabs (Overview, Stats, Models) with daily/weekly/monthly views
CLI Commands — daily, weekly, monthly, stats with JSON output support
Usage Reports — Shareable text & SVG receipts via toktrack report
Fast on huge histories — simd-json + rayon parallel parsing (~3 GiB/s); cached runs in ~0.04s

Remote Codex Sources

toktrack can include Codex session logs from SSH servers by syncing remote JSONL files into a local snapshot and parsing them with the existing Codex parser. It uses your existing ssh/rsync setup and never stores SSH passwords or keys.

Create ~/.toktrack/config.toml:

default_remotes = ["devbox"]

[[remotes]]
name = "devbox"
target = "ubuntu@devbox"

[remotes.paths]
codex = "~/.codex/sessions"

[[remotes]]
name = "prod"
target = "prod-alias"

[remotes.paths]
codex = "/home/codex/.codex/sessions"

You can also manage the same config from the CLI:

toktrack remote add devbox ubuntu@devbox --default
toktrack remote add prod prod-alias --codex-path /home/codex/.codex/sessions
toktrack remote default add prod
toktrack remote default remove devbox
toktrack remote remove prod
toktrack remote list

By default, commands read local data plus default_remotes:

toktrack report
toktrack daily --json

Override the configured defaults when needed:

toktrack --remote prod report      # local + default_remotes + prod
toktrack --all-remotes stats       # local + every configured remote
toktrack --local-only report       # local only

Remote Codex sources appear as codex@<remote-name> and use separate cache files such as ~/.toktrack/cache/codex@devbox_daily.json. If a remote sync fails, toktrack warns and continues with local data plus any existing snapshot/cache for that remote.

Supported AI CLIs

CLI	Status	Data Location
Claude Code	✅	`~/.claude/projects/`
Codex CLI	✅	`~/.codex/sessions/`
Gemini CLI	✅	`~/.gemini/tmp/*/chats/`
Qwen Code	✅	`~/.qwen/tmp/*/chats/`
OpenCode	✅	`~/.local/share/opencode/storage/message/`
PI Agent	✅	`~/.pi/agent/sessions/`
Antigravity	⚠️ detected, unsupported	`~/.gemini/antigravity-cli/` (no file-readable token usage)

Costs from sources that don't record their own price (Gemini, Qwen, Codex, and modern Claude logs) are computed from LiteLLM pricing and shown with a ~ marker (estimated). Pricing works offline via a bundled snapshot when the network is unavailable.

Environment Variables

Each source's data directory can be overridden (matching the upstream CLI's own variable):

Variable	Source	Default
`CLAUDE_CONFIG_DIR`	Claude Code (root)	`~/.claude` (+ `/projects`)
`CODEX_HOME`	Codex CLI (root)	`~/.codex` (+ `/sessions`)
`GEMINI_CLI_HOME`	Gemini CLI (home root)	`~` (+ `/.gemini/tmp`)
`QWEN_HOME`	Qwen Code	`~/.qwen` (+ `/tmp`)
`OPENCODE_DATA_DIR` / `XDG_DATA_HOME`	OpenCode	`~/.local/share/opencode`
`PI_CODING_AGENT_SESSION_DIR` (then `PI_AGENT_DIR`)	PI Agent	`~/.pi/agent/sessions`

export CLAUDE_CONFIG_DIR="/path/to/.claude"

Custom pricing (including web_search / web_fetch per-request rates) can be set in ~/.toktrack/pricing.toml.

Performance

Run	Time
First run (cold)	~1.0s
Daily use (cached)	~0.04s

Measured on Apple Silicon with 2,000+ JSONL files (3.4 GB). The persistent cache means only the current day is recomputed on each run — past days are read straight from cache, so daily use stays instant no matter how large your history grows.

Why it's fast: SIMD JSON parsing (simd-json) + parallel processing (rayon) = ~3 GiB/s throughput on the cold path.

Data Preservation

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.

CLI Data Retention Policies (The Hidden Risk)

CLI	Default Retention	Policy
Claude Code	30 days	`cleanupPeriodDays` (default: 30)
Gemini CLI	Unlimited	opt-in `sessionRetention`
Codex CLI	Unlimited	size-cap only (`max_bytes`)

toktrack Cache Structure

~/.toktrack/
├── cache/
│   ├── claude-code_daily.json   # Daily cost summaries
│   ├── codex_daily.json
│   ├── codex@devbox_daily.json
│   ├── gemini_daily.json
│   ├── opencode_daily.json
│   └── pi-agent_daily.json
├── remotes/
│   └── devbox/codex/sessions/   # Synced remote Codex JSONL snapshots
├── config.toml                  # Optional remote source configuration
└── pricing.json                 # LiteLLM pricing (1h TTL)

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.

See Exactly What's Preserved

toktrack audit shows, per source and per day, whether the data is still live (raw session file on disk), cache-only (the CLI deleted the raw file — only toktrack still has it), or missing (no data — an unused day, or one lost before toktrack first saw it; never claimed as a loss).

$ toktrack audit

Data preservation audit (2026-06-08)

  claude-code   2025-12-22 → 2026-06-08
    live (raw on disk):         79 days
    preserved (CLI deleted):    83 days
    no data (unused or lost):    7 days
  ...

  ► 100 days of cost history preserved that your CLIs already deleted.

Use toktrack audit --json for the full per-day breakdown, or open the Audit tab in the TUI (press 4) for a visual coverage map.

Disable Claude Code Auto-Deletion

// ~/.claude/settings.json
{
  "cleanupPeriodDays": 9999999999
}

Reset Cache

rm -rf ~/.toktrack/cache/

The next run will rebuild the cache from available session data.

How It Works

architecture

Cold path (first run): Full glob scan → parallel SIMD parsing → build cache → aggregate.

Warm path (cached): Load cached summaries → parse only recent files (yesterday midnight mtime filter) → merge → aggregate.
