Know exactly what
your AI actually costs

Track every token, every dollar — per feature, per user, per project. Self-hosted, privacy-first. You keep your API keys.

       Dashboard: costs by feature, user, project

Everything you need

Full visibility into AI spending with zero data exposure.

📊

Real-Time Dashboard

See costs as they happen. Break down by feature, user, project, or model. Spot anomalies before they become problems.

🔒

Privacy First

Self-hosted. Your API keys pass through — never stored. Only token counts and costs are recorded. No prompts, no responses.

⚡

5-Minute Setup

Docker Compose brings up everything: PostgreSQL, Redis, API, and dashboard. One command to deploy.

🔌

Multiple Integrations

Python SDK, JavaScript SDK, proxy mode, or direct API. Works with OpenAI, Anthropic, and more.

🏷️

Tag Everything

Tag by feature, user, team, or environment. Context tags let you slice costs any way you need.

🚨

Budget Alerts

Set spending limits per project or feature. Get notified before costs spiral. Rate limiting built in.
