WhyLabs

The free plan covers 10M predictions a month, one project, one user and daily monitoring, with no credit card needed.

That is the entry point to WhyLabs, an AI observability platform that monitors machine learning models and data, and also secures LLM applications.

The monitoring side starts free for individuals.

The Expert plan costs $125 a month and raises the limits to three projects, five users and 100M predictions, with hourly monitoring for one LLM and email support.

Enterprise is custom priced and adds unlimited users and predictions, 24x7 support and a private Slack or Teams channel.

WhyLabs Secure is the separate security product.

It adds policy guardrails and tracing for AI apps, and you can try every capability free for 14 days.

The paid Expert tier includes five out-of-the-box policy rulesets, up to 100,000 traces a month and Private Link support for AWS or Azure.
