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
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.
Configuration intelligence platform
CUE Hub
The full power of CUE on your existing configuration. Pre-deployment checks and impact analysis on the stack you already run.
CUE and AI
Check AI-written configuration with rules, not another model
Another model can review what an AI writes, and it will often be right. To know a change breaks no rule or policy, you need a check that gives the same answer every time. CUE checks every change against your schemas and policies, and when one fails it tells you which rule broke.
