Open source

Langfuse is open source to

• establish full transparency
• enable the community to self-host
• collaborate on integrations with other tools and frameworks.

Self-host vs cloud

Langfuse is simple to use locally and self-hosted. The core team offers Langfuse cloud as a managed solution to make it easier to get started with Langfuse and reduce the operational overhead of running it with high availability in production.

License

Langfuse is available under an MIT license (opens in a new tab), except for the /ee folder of the repository, if applicable.

We are currently focusing 100% of our energy on the open source part. We may in the future consider commercializing premium features as part of an enterprise version. Please reach out to us if you have specific requirements: enterprise@langfuse.com
