Hi everyone, we’ve got big news! Starting today, all Langfuse product features are available as free OSS (MIT license).

You can now upgrade your self-hosted Langfuse to access features like:
- Managed LLM-as-a-Judge evaluations
- Annotation queues
- Prompt experiments
- LLM playground

We’re incredibly grateful for the support of this amazing community and can’t wait to hear your feedback on the new features!
