Langfuse Open Sources All Product Features: Building the Open LLM Engineering Platform

Langfuse is open-sourcing all its product features, including managed vector databases, evaluation tools, and the Playground, to accelerate community application iteration and gather feedback. This move stems from Langfuse's vision to be the leading open-source LLM engineering platform. By opening core features, they aim to foster trust, collaboration, accelerate adoption, and iterate faster. Langfuse started as an open-source project and remains committed to this principle. Only Enterprise security and platform team features (e.g., SCIM, audit logs, data retention policies) remain commercially licensed; the rest are MIT licensed. With over 8,000 monthly active self-hosted instances, this move solidifies Langfuse as the top choice for a powerful, truly open-source platform in LLMOps.
