When NOT to use langfuse
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- If you are looking for a fully managed service without the need for self-hosting, as Langfuse requires setting up and maintaining the infrastructure yourself.
- When you need enterprise features that are not covered by the open-source version, as the `ee` folders are not open-source and may require additional licensing or services.
