Evidently AI
Open-source and Cloud platform for evaluating and monitoring ML and LLM systems, including drift, quality checks, and dashboards teams can run in CI or production.
ML and LLM teams that want open-source evaluation reports with an optional Cloud path for collaboration and scale.
Enterprises standardized on a full AI observability suite with deep agent tracing and paid support already on contract.
Co-founded by Emeli Dral.
Verdict
Evidently AI is a good fit when your team already thinks in test reports and wants monitoring that starts in open source. Published Cloud plans make it easy to try before an enterprise conversation. Practitioners like clear eval reports; buyers who need the deepest production agent tracing may still prefer Arize or Fiddler-class platforms.
