Telemetry is analytics for coding agents. Your agent instruments your software to send data to Telemetry, then queries Telemetry to tell you how your code is performing. Ask in plain English. Get a number back. It works with Anthropic Claude Code, OpenAI Codex, Cursor, and GitHub Copilot, with use cases including model costs, API reliability, background jobs, product analytics, and security events.

Try it free, no signup. The anonymous key can already send and query events; saved queries, dashboards, and alerts need a free account. Use a JavaScript, Python, Go, Rust, Ruby, or PHP SDK, or cURL. Every plan includes SQL queries, dashboards, alerts, and team collaboration.

- **Free:** $0 per user/month, with 1 GB storage and 1 hour of query runtime per month.

- **Business:** $12 per user/month, with 10 GB storage and 10 hours of query runtime per month.

- **Enterprise:** $99 per user/month, with 1 TB storage, 100 hours of query runtime per month, custom retention policies, and a dedicated account manager.
