Catch AI failures before your users do

Your AI is already breaking in production.

Automatically test and validate your LLM outputs so you can ship reliable AI features without guesswork.

Everything you need to ship reliable AI

Create Tests Without Writing Code

Define test cases in simple, readable files your whole team can understand.

Run Tests on Every Deploy

Integrate with your CI/CD and catch regressions before they reach production.

Understand Why Your AI Fails

See detailed reports, compare outputs, and quickly identify what’s going wrong.

Scale Testing Without Slowing Down

Run hundreds or thousands of tests fast with parallel execution.

Keep Your Data Secure

Enterprise-grade security with self-hosted options. Your data stays under your control.

Track Improvements Over Time
