**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](README.md) | [繁體中文](README.zh-TW.md) | [简体中文](README.zh-CN.md)

> 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](https://github.com/BerriAI/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

## ✨ Key Features

| Feature                  | Description                                                          |
| ------------------------ | -------------------------------------------------------------------- |
| 🤖 **Multi-Provider**    | Claude Code, Codex, Copilot, and Gemini — all in one place           |
| 💵 **Smart Pricing**     | Fuzzy model matching + daily cache from LiteLLM                      |
| 🎨 **4 Display Modes**   | Interactive TUI, static table, plain text, and JSON                  |
| 📈 **Dual Analysis**     | Token/cost stats (`usage`) + code operation stats (`analysis`)       |
| 🪶 **Ultra-Lightweight** | Under ~50 MB RSS in the TUI, streaming JSONL parse — built with Rust |
| 🔄 **Live Updates**      | Real-time dashboard refreshes every second                           |
| 💾 **Efficient Caching** | Smart daily cache reduces API calls                                  |

#### Method 1: Install from npm

**Prerequisites**: [Node.js](https://nodejs.org/) v22 or higher

Choose one of the following package names (they are identical):

```bash
# Main package
npm install -g vibe-coding-tracker

# Short alias with scope

## 💰 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

```bash
# 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

```bash
# 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):

```bash
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](https://github.com/BerriAI/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

---

## 🐳 Docker Support

```bash
# Build image
docker build -f docker/Dockerfile --target prod -t vibe_coding_tracker:latest .

# Run with your sessions
