## What it is
A generic Go library for data validation and filtering that supports validating Map, Struct, and HTTP Request (Form, JSON, url.Values) data. It includes 70+ built-in validators, data filters/converters, scene-based validation, custom validators, and i18n-aware error messages.

## Use cases
- validate form data in a go web app
- validate json request body in gin or echo
- sanitize and convert input before validation
- validate struct fields with tags
- custom error messages and field translations for validation
- validate different fields per scene
- validate individual values against rule strings

## When to choose
- you need a batteries-included Go validation library with many built-in validators and filters
- you want automatic validation of http.Request data based on Content-Type
- you need i18n error messages or per-field translations
- you want framework-agnostic validation usable with Gin, Echo, Chi, etc.

## When to avoid
- you only need simple struct-tag validation and prefer a minimal dependency-free approach
- your framework already provides a validation layer you must use
- you need validation in a non-Go language

## Facets
- artifact type: library
- maturity: active
- function: form-handling, serialization
- domain: backend, web-development, developer-tools
- platform: go, cross-platform
- tags: validation, data-filtering, sanitization, struct-tags, i18n, http-request-validation
