Get Started

“For anyone starting from scratch, this is a no-brainer — it’s basically Datadog for token tracking.”

Brad Schneider

Know exactly what it costs to deploy your agents.

Crystil tracks your LLM costs by task, agent, and customer so you can finally see what it really costs to deploy and run your agents. Compare usage across models and providers like OpenAI, Anthropic, and Gemini in one place.

Protect margins and price confidently as you scale.

With real-time cost visibility, you can pick and test the right pricing model, whether it’s cost-plus, token-based, subscription, or outcome-based. Keep margins strong as usage grows, and never worry about your LLM costs outpacing your revenue.

Protect margins and price confidently as you scale.

Protect margins and price confidently as you scale.

Simple integration. Instant visibility.

Add Crystil with just one line of code. Every LLM call you make is automatically wrapped with a transaction ID, classified by task and tool, and tracked in real time. No spreadsheets, no custom logging.
