Early access

Do you know where your LLM budget is actually going?

Most teams pay their OpenAI or Anthropic bill every month without knowing which feature, user, or agent loop is burning the most tokens. TokenCurb shows you exactly where your money goes — and how to spend less.

No spam. No credit card. We'll reach out when early access opens.

How much can I save?

Teams with per-feature visibility typically cut LLM spend by ~35% through routing, loop fixes, and spike detection.
