CUE + CENTRAL REGISTRY
ACCESS THE SCHEMA LIBRARY
Access a rich library of tested schemas for Kubernetes, GitHub Actions, Azure Pipelines, Argo Workflows and many more to make validation easy - independent of your current configuration.
COMPATIBLE WITH YOUR SYSTEM
There is no need to change how you work. CUE natively understands most data formats, standards and languages. Sign up with the Central Registry and start validating your services with CUE right away – without any infrastructure changes.
DRASTICALLY REDUCE BOILERPLATE
CUE can significantly reduce boilerplate compared to most configuration formats. By cutting the clutter, you make your files easier to read, simpler to understand and uncomplicated to maintain.
REDUCE RISK, BOOST EFFICIENCY
Configuration errors are costly! With the Central Registry, you can easily enforce consistency and make sure all your services are validated and work as intended, before they cause run-time errors.
NATIVE DEPENDENCY MANAGEMENT
Reduce chaos with CUE’s builtin support for the Central Registry for native dependency management and build your own CUE tools that can do the same.
OCI-BASED
Seamlessly integrate and run all the features of the Central Registry on your own OCI registry - on prem, compliant, safe.
COMPOSABLE BUILDING BLOCKS
Don’t treat your configuration as silos. Use CUE to create templates as reusable building blocks and share them via the Central Registry, with your colleagues or users.
THE CUE LANGUAGE

VALIDATION
You wouldn’t ship software without testing; why treat configurations any differently? With CUE, you can easily validate your configuration and ensure it works exactly as intended.
EFFICIENT
CUE eliminates up to 90% of your configurations’ boilerplate. By removing repetitive clutter, you make your configuration simpler to understand, maintain, and validate – for everyone involved.
COMPATIBLE
Configuration is messy. CUE was designed to be introduced bottom-up, avoiding whole-system rebuilds. CUE integrates with major data formats and popular developer tools, letting you improve your infrastructure without rebuilding it.
OPEN-SOURCE
CUE is fully open source, developed by CUE Labs and a thriving CUE community! Freely use, adapt, and contribute—shaping CUE’s future alongside your fellow users.
