Been using Langfuse OSS for almost 15 months from the start. By far the best solution. No dark patterns found in other projects such as Portkey.

All core features are fully open-source and identical to those in Langfuse Cloud, with no limitations on capabilities or scalability (e.g. all v3 infrastructure changes).

We also offer some optional commercial add-on features that can help iterate faster or support very large teams using Langfuse. However, these features are entirely optional and we do our best to be transparent about this across our docs.
