Would not choose if
- Teams solely seeking lightweight batch logging without a dedicated ML platform team.
- Organizations needing LLM evaluation strictly built from the ground up, rather than adapted from general ML monitoring.
- Buyers who require a simple, fully managed cloud-only solution without any self-hosting or air-gapped deployment options.
