## Shortlist

### 1. Arize

Managed agent observability and evals with an ELv2-licensed self-hosted Phoenix option.

**Where it improves on Langfuse:**
- [Agent permissions: yes — Self-hosted Phoenix has admin, member, and viewer roles with explicitly different mutation permissions.](https://arize.com/docs/phoenix/self-hosting/features/authentication)

**Trade-offs against Langfuse:**
- [Open source: partial — Phoenix is the vendor's ELv2-licensed OSS core, while AX is presented separately as a managed platform.](https://arize.com/phoenix/)
