Our verdict on NannyML
NannyML is machine learning model monitoring software for data science teams operating models in production. Its central use case is estimating model performance when ground-truth labels are delayed or unavailable, while also monitoring realized performance against targets. The platform covers concept drift, univariate and multivariate covariate drift, data-quality issues, subgroup segmentation, custom metrics, and custom thresholds. Teams can access NannyML through web, API, or self-hosted deployment options, including the open-source library for self-managed monitoring.
The standout capability is performance estimation without ground-truth labels, which addresses monitoring situations where outcome data arrives late or is not available. NannyML also supports realized performance monitoring once targets are available, allowing teams to compare estimated and observed results. Segmentation adds more granular analysis across subgroups, while ranked alerts, email and Slack notifications, and webhook actions support operational follow-up and retraining workflows. Integrations include Slack, email, webhooks, AWS Marketplace, and Azure Marketplace.
NannyML has a freemium model with an Open Source plan for self-managed use and a 30-day free trial on listed paid tiers. The published pricing presents Starter at $399 per month and Scale at $999 per month, while a separate beta pricing table shows Starter at $99 per month and Pro at $3,800 per month. Scale includes monitoring in your cloud and private Slack; Enterprise adds unlimited models, unlimited predictions, and 24/7 support. The product suits teams prioritizing label-free monitoring and flexible deployment. Teams needing monitoring beyond two models should review the applicable plan limits or consider an alternative.
