JOI + joi-to-typescript - this, albeit fast, is the largest package and requires 2 packages to make it work so we can automatically convert from the schema to TS. Probably a bit glitchy too. Meh support (not too many commits lately).
Zod - zero dependencies. Not sure on speed (seems meh) but great support and active devs. Type inference is decent. Sorta leaning towards this one
Superstruct - severely lacks in existing featureset.
Class validator - uses classes instead so types are sorta built in. Get nice annotation stuff. Pretty fast
Yup - decent but slower than JOI (smaller bundle though). Familiar feeling schema but TS type inference is not the best. Probably gets better with time. Large support. Not actively developed right now
