Cue, an open-source data validation language

Can a useful comparison be made between Cue and Clojure.spec?

Philosophically they seem very similar, but at a glance[0] it seems like clojure.spec is quite a bit more expressive. Also spec lives in your REPL session and in your source code, while Cue is meant to be used as a CLI, so there is a completely different approach.

CUE is currently centered around its CLI, but AIUI, that's not the long-term goal. i read in some CUE issue somewhere that the goal is shifting towards enabling frameworks rather than driving people to the CLI, though i don't have a link.

Our use of CUE in Grafana is an example of framework-style usage. It is a hard requirement that users never have to install the CUE CLI to perform any of our planned CUE-related tasks; rather, the needed tooling is baked into Go packages we export, and things like grafana-cli. (Avoiding a dependency on the CUE CLI also gives us a defense mechanism against breaking changes)
