Open Source
Langfuse is open source for the following reasons:
- To establish complete transparency
- To enable the community to self-host and contribute (opens in a new tab)
- To collaborate on integrations with various other open-source tools and frameworks
- To assure users that Langfuse is open and does not impose lock-in, and that production traces are user data that can be exported/fetched at any time

Self-host vs Langfuse Cloud
The Langfuse team provides Langfuse Cloud as a managed solution to simplify the initial setup of Langfuse and to minimize the operational overhead of maintaining high availability in production. Get started for free on: https://cloud.langfuse.com (opens in a new tab).
Alternatively, Langfuse can be used locally and self-hosted.
