Langfuse is the open source LLM Engineering Platform. It provides observability, tracing, evaluations, prompt management, playground and metrics to debug and improve LLM apps. Langfuse is open. It works with any model, framework and you can export all data.
Hi Product Hunt 👋👋👋
I’m Clemens, co-founder of Langfuse (with @marc_klingen and @max_deichmann). We are so excited to be live on Product Hunt again today launching Langfuse 2.0!
We originally launched Langfuse right here in late August 2023 and made it to #1 Product of the Day. Earlier this year we were lucky enough to be awarded a Golden Kitty in the AI Infra category for 2023! Product Hunt holds a special place in our heart and company history.
Langfuse has come a long way. Last year, we set out to build open source observability and analytics for LLM apps. We saw a need and gap for a dev-focussed, open source and self-hostable product that allows for complex tracing and nesting of LLM and other workloads.
We are excited to introduce Langfuse 2.0 today. We have moved from an observability tool to a platform for LLM engineering.
The scope is now wider and the core product has matured so much since last year.
A few things you should know about:
👣 Tracing: TS & Python (new: decorator) + OpenAI, Llama Index, Langchain, Litellm + more
🤨 Eval Service: Automatically run evals against all new incoming traces
💾 Datasets: Collect, test and run fine-tuning, testing, and golden datasets in Langfuse
💯 Metrics: Dashboards and analytics on cost, latency and quality
🤖 Prompt Management: Version and deploy prompts from within Langfuse
🕹️ LLM Playground: Engineer your prompts with context in Langfuse
🏎️ Export & Fine Tune: Open GET API and csv/JSON exports to build downstream use cases
🚄 Scale: We’ve invested significantly in scaling and resilience as we’ve scaled to thousands of users and handle millions of events a day
