Introduction #

ccusage is a local CLI for understanding coding (agent) CLI token usage and estimated costs across Claude Code, Codex, OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, GitHub Copilot CLI, Gemini CLI, and Grok Build CLI.

The original “cc” came from Claude Code usage and now also fits Codex CLI usage. As OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, Gemini CLI, Grok Build CLI, and other coding (agent) CLIs became part of the same workflow, ccusage expanded into a general name for local coding CLI usage analysis.

The Problem #

Modern coding (agent) CLI usage is split across several local data formats. That makes basic questions hard to answer:

• How much am I actually using each coding CLI?
• Which conversations are the most expensive?
• What would I be paying on a pay-per-use plan?
• Which projects, sessions, or weeks are driving usage?

The Solution #

ccusage reads the local usage files that coding CLIs already generate and provides:

• All Sources by Default - Claude Code, Codex, OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, GitHub Copilot CLI, Gemini CLI, and Grok Build CLI in one CLI
• Usage Views - Daily, weekly, monthly, and session-based breakdowns
• Cost Analysis - Estimated costs based on token usage and model pricing
• Focused Data Source Views - Start with all detected sources, then narrow the same usage views to one source when needed
• Data Source Pages - Source-specific setup and extra features live with each supported data source
• Multiple Formats - Beautiful tables or JSON for further analysis

How It Works #

1. Coding CLIs generate local usage files containing usage data
2. ccusage reads these files from your local machine
3. Analyzes and aggregates the data by date, session, or time blocks
4. Calculates estimated costs using model pricing information
5. Presents results in beautiful tables or JSON format

Key Features #

🚀 Direct Execution #

You can run ccusage without a global install using bunx ccusage (recommended), pnpm dlx ccusage, or npx ccusage@latest.

📊 Usage Views #

• All Sources (Default) - Aggregates every detected supported source
• Daily Usage - Usage aggregated by calendar date
• Weekly Usage - Usage aggregated by week with configurable start day
• Monthly Usage - Monthly summaries with trends
• Session Usage - Per-conversation analysis

💰 Cost Analysis #

• Estimated costs based on token counts and model pricing
• Support for different cost calculation modes
• Model-specific pricing across supported providers
• Cache token cost calculation

Data Source Pages #

Each data source page covers the details that only apply to that source, including custom directories, pricing notes, and source-specific commands.

🔧 Flexible Configuration #

• JSON Configuration Files - Set defaults for all commands or customize per-command
• IDE Support - JSON Schema for autocomplete and validation
• Priority-based Settings - CLI args > local config > user config > defaults
• Environment Variables - Traditional configuration options
• Custom Date Filtering - Flexible time range selection and sorting
• Offline Mode - Cached pricing data for air-gapped environments

Data Sources #

ccusage reads from local coding CLI data directories:

Agent	ID	Default data location
Claude Code	claude	~/.config/claude/projects/, ~/.claude/
Codex	codex	${CODEX_HOME:-~/.codex}
OpenCode	opencode	${OPENCODE_DATA_DIR:-~/.local/share/opencode}
Amp	amp	${AMP_DATA_DIR:-~/.local/share/amp}
Droid	droid	${DROID_SESSIONS_DIR:-~/.factory/sessions}
Codebuff	codebuff	${CODEBUFF_DATA_DIR:-~/.config/manicode}
Hermes Agent	hermes	${HERMES_HOME:-~/.hermes}/state.db
pi-agent	pi	${PI_AGENT_DIR:-~/.pi/agent/sessions}
Goose	goose	Standard Goose data roots or GOOSE_PATH_ROOT
OpenClaw	openclaw	${OPENCLAW_DIR:-~/.openclaw}
Kilo	kilo	${KILO_DATA_DIR:-~/.local/share/kilo}
Kimi	kimi	${KIMI_DATA_DIR:-~/.kimi} (also ~/.kimi-code)
Qwen	qwen	${QWEN_DATA_DIR:-~/.qwen}
Copilot CLI	copilot	~/.copilot/otel/*.jsonl
Gemini CLI	gemini	${GEMINI_DATA_DIR:-~/.gemini/tmp}
Grok Build CLI	grok	${GROK_HOME:-~/.grok}

The tool automatically detects available data and aggregates all supported coding CLIs by default. Source-specific environment variables that support multiple roots can contain comma-separated directories, which lets unified reports combine current profiles and archives.

Some coding agents have been investigated but are not supported because their local files do not contain reliable token usage. See Source Support Q&A for the current notes on Antigravity CLI, legacy Grok CLI SQLite data, and Devin CLI.

Report Shape #

Run ccusage without a source name to aggregate all detected sources:

ccusage daily
ccusage weekly
ccusage monthly
ccusage session

Add a data source namespace when you want the same report focused on one source:

ccusage claude daily
ccusage codex daily --speed fast
ccusage opencode weekly
ccusage amp session
ccusage droid daily
ccusage codebuff daily
ccusage hermes daily
ccusage pi monthly
ccusage goose daily
ccusage openclaw daily
ccusage kilo daily
ccusage kimi daily
ccusage qwen daily
ccusage copilot daily
ccusage gemini daily
ccusage grok daily

Use ccusage <source> <report> only when you want to narrow a report to one source.

Privacy & Security #

• 100% Local - All analysis happens on your machine
• No Data Transmission - Your usage data never leaves your computer
• Read-Only - ccusage only reads files, never modifies them
• Open Source - Full transparency in how your data is processed

Limitations #

::: warning Important Limitations

• Local Files Only - Only analyzes data from your current machine
• Language Model Tokens - API calls for tools like Web Search are not included
• Estimate Accuracy - Costs are estimates and may not reflect actual billing :::
