CUE is trusted by thousands of organizations

50%+ of major outages are caused by misconfigurations

They cost billions and damage trust every year, and they are rarely caught by tests. We build tried-and-tested tools, used by industry leaders, that catch them before they ship.

Two ways to catch mistakes before they deploy

Both start from the configuration you have today. Nothing needs to be rewritten on day one.

    The CUE configuration language

    CUE

    The open source language to define, check, and generate configuration. It natively understands your existing configuration, so you can adopt it one file at a time.

CUE and AI

Check AI-written configuration with rules, not another model

A model reviewing a model gives you a better opinion. CUE gives you a check: the same answer every time, against the schemas and policies you wrote. If it passes, no rule is broken. If it fails, you know which one.
