Show HN: govalid – Go validation without reflection (5-44x faster)

https://github.com/sivchari/govalid
2•sivchari•2h ago
I got frustrated with runtime reflection in Go validators, so I built a codegen approach instead. govalid reads struct markers and generates plain Go validation code. No reflection, no allocations at runtime, 5-44x faster than go-playground/validator. Also supports CEL for complex rules. Feedback welcome :)
