CueBlox was an experimental headless CMS built on top of CUE. The idea was to use CUE schemas to define content types, validate Markdown/YAML content against them, and expose the result as a typed content API — effectively a Hugo/Netlify CMS alternative where the schema language was CUE instead of bespoke YAML.
The project was created by David Flanagan (Rawkode) and is no longer actively developed. The interesting ideas from it — CUE as the schema layer for structured content and configuration — have been picked up more broadly by the CUE ecosystem itself and by tools like Timoni for Kubernetes packaging.
If you’re looking at CueBlox today, you almost certainly want something else: Astro’s content collections, Keystatic, Sanity, or a plain Git-backed setup with CUE used directly for validation.
