Aporia

Aporia monitors models in production, watching for data drift, performance drops and unusual predictions. It added a guardrails product that screens LLM prompts and responses for hallucinations, PII and policy violations. It was acquired by Coralogix.

Customization is a highlight, with the ability to write your own monitors. Alerts go to Slack or email so teams can respond quickly.

It is aimed at ML teams that want a unified view over classic models and generative apps.
