NannyML

NannyML Cloud is an ML model monitoring platform, recently joining forces with Soda, that estimates model performance in real time without requiring ground-truth labels — using research-driven performance-estimation techniques — with enterprise clients including Walmart, TUI, Allianz, and UBS. It detects both concept drift and data drift with granular univariate and multivariate analysis, ranks alerts by linking data drift to actual performance impact (reducing false alarms rather than flooding teams with noise), triggers retraining actions automatically via webhooks, and deploys securely inside a customer's own cloud infrastructure. A free trial and demo booking are both available; specific pricing tiers require checking the pricing page. Good fit for an ML team running models in production that wants to know when performance is actually degrading — not just when input data statistically drifts — without waiting for delayed or absent ground-truth labels.
