Helicone

Join thousands of developers and companies who have streamlined their LLM-powered application infrastructure with Helicone's open-source solutions.

Designed to work out of the box, all you have to do is change one line of code and you'll have full observability and monitoring into your application. Understand your cost breakdown, user behavior, and much more.

We support ANY model at ANY scale so bring on over your fine tuned models, Claude, etc.

We also provide a rich suite of tooling that is purpose-built for LLM-developers that helps you get back to building your product rather than building infrastructure:

• labeling / feedback
• caching
• rate limiting
• alerts
• ETL
