## Shortlist

### 1. Langfuse

Open-source, self-hostable tracing and evaluation platform for LLM applications.

**Where it improves on Arize:**
- [Open source: yes — Langfuse publishes its platform as open-source software and explicitly presents it as self-hostable and extensible.](https://langfuse.com/docs)

**Trade-offs against Arize:**
- [Agent permissions: partial — Halo pauses before changing data or configuration, though a conversation can enable Always approve.](https://langfuse.com/docs/api-and-data-platform/features/halo)
