LimitationsNo longer an independent commercial vendor - acquired by Apple in 2025 and operations discontinued; only the open-source projects remain, with no vendor support, SLAs, or active product roadmap.Now part of Coralogix, so the standalone product roadmap and branding are being absorbed into a larger platform, which may affect independent adoption; public list of named customers is limited, and buyers should confirm current packaging post-acquisition.

Choose WhyLabs if teams seeking free, open-source, privacy-preserving ML and data monitoring via whylogs and LangKit, rather than a supported commercial product.

Choose Aporia if mL and platform teams in regulated industries needing production ML monitoring plus real-time GenAI guardrails, now within the Coralogix observability ecosystem

Neither is a substitute for a governance program. Whichever you pick, you still need people who can define the policies the tool enforces.
