Vibe Coding Tracker - AI coding assistant telemetry/usage parser, aggregate JSONL events into CodeAnalysis results

Vibe Coding Tracker — AI Coding Assistant Usage Tracker

Track your AI coding costs in real-time. Vibe Coding Tracker is a lightweight, high-performance CLI tool built in Rust that monitors and analyzes your Claude Code, Codex, Copilot, and Gemini usage — with detailed cost breakdowns, token statistics, and code operation insights, all while keeping the memory footprint minimal.

English | 繁體中文 | 简体中文

Note: CLI examples use the short alias vct. If you installed via npm/pip/cargo, the binary might be named vibe_coding_tracker or vct. Create an alias or replace vct with the full name when running commands if needed.

🎯 Why Vibe Coding Tracker?

💰 Know Your Costs

Stop wondering how much your AI coding sessions cost. Get real-time cost tracking with automatic pricing updates from LiteLLM.

🪶 Ultra-Lightweight

Built with Rust for minimal resource footprint. The interactive TUI dashboard typically sits at under ~50 MB of resident memory once the first refresh is done, even with hundreds of long-context sessions on disk — no Electron, no bloated runtimes. The usage path parses each session file in a lean usage-only mode and bypasses the cache, and we tune glibc's arena count at startup to keep long-running RSS honest.

📊 Beautiful Visualizations

Choose your preferred view:

• Interactive Dashboard: Auto-refreshing terminal UI with live updates
• Static Reports: Professional tables for documentation
• Script-Friendly: Plain text and JSON for automation
• Full Precision: Export exact costs for accounting

🚀 Zero Configuration

Automatically detects and processes logs from Claude Code, Codex, Copilot, and Gemini. No setup required — just run and analyze.

🎨 Rich Insights

• Token usage by model and date
• Cost breakdown by cache types (read / create)
• File operations tracking (edit, read, write lines)
• Tool call history (Bash, Edit, Read, Write, TodoWrite)
• Per-provider daily averages

📖 Command Guide

🔍 Quick Reference

vct <COMMAND> [OPTIONS]
# Replace with `vibe_coding_tracker` if you are using the full binary name

Commands:
  analysis    Analyze JSONL conversation files (single file or all sessions)
  usage       Display token usage statistics
  version     Display version information
  update      Update to the latest version from GitHub releases
  help        Print this message or the help of the given subcommand(s)

Time range flags (shared by usage and analysis, mutually exclusive, default --all):

Flag	Window
--daily	Sessions modified today
--weekly	Current ISO week (Monday → today)
--monthly	Current calendar month
--all	Every session on disk (default)

---

💰 Usage Command

Track your spending across all AI coding sessions.

Flags

Flag	Purpose
(none)	Interactive TUI dashboard (default)
--table	Static table, no TUI
--text	Plain text, script-friendly
--json	JSON with enriched pricing metadata
--daily / --weekly / --monthly / --all	Time range filter (see table above)

Basic Usage

# Interactive dashboard (recommended)
vct usage

# Static table for reports
vct usage --table

# Plain text for scripts
vct usage --text

# JSON for data processing (includes cost_usd and matched_model fields)
vct usage --json

# Combine time range with output format
vct usage --weekly
vct usage --table --monthly
vct usage --json --daily

[!NOTE] Model rows are sorted by cost in ascending order, so the highest-spending model sits right above the TOTAL row. This applies to the interactive dashboard, --table, and --text output; --json preserves the same order.

🔄 Update Command

Keep your installation up-to-date automatically.

The update command works for all installation methods (npm/pip/cargo/manual) by directly downloading and replacing the binary from GitHub releases.

Basic Usage

# Check for updates
vct update --check

# Interactive update with confirmation
vct update

# Force update — always downloads latest version
vct update --force

Preview (vct update --check)

📋 Current version: v0.5.10
🔍 Checking for latest release...
✅ Latest version: v0.5.10 — you are up to date!

---

🏷️ Version Command

Report the embedded build metadata (binary version, Rust toolchain, Cargo version):

vct version          # Pretty table
vct version --text   # One-field-per-line, script-friendly
vct version --json   # Machine-readable JSON

The binary version is produced at build time by build.rs from git describe, so development builds include commit count + short SHA + dirty suffix when applicable.

💡 Smart Pricing System

How It Works

1. Automatic Updates: Fetches pricing from LiteLLM daily
2. Smart Caching: Stores pricing in ~/.vibe_coding_tracker/ for 24 hours
3. Fuzzy Matching: Finds best match even for custom model names
4. Always Accurate: Ensures you get the latest pricing

Model Matching

Priority Order:

1. ✅ Exact Match: claude-sonnet-4 → claude-sonnet-4
2. 🔄 Normalized: claude-sonnet-4-20250514 → claude-sonnet-4
3. 🔍 Substring: custom-gpt-4 → gpt-4
4. 🎯 Fuzzy (AI-powered): Uses Jaro-Winkler similarity (70% threshold)
5. 💵 Fallback: Shows $0.00 if no match found
