A true gem among similar products.
thank you 💎
A great product to productionize your LLM applications. Once you create a prototype, the next step is understanding the cost structure, and tracing the paths - and Langfuse helps you to solve those challenges. The new decorators make it easy to track anything easily from your code. Good luck with the launch!
thanks Tevfik, appreciate your feedback. The decorator has been a big step up recently, glad you like it!
as an LLM engineer, working with langfuse is a no brainer!!
thank you Alex! Langfuse UI is (partially) built by you
