In 2026 the Ruby ecosystem offers three mature answers — ActiveModel::Validations baked into Rails, the dry-rb ecosystem&rsquo;s dry-validation, and Trailblazer&rsquo;s Reform form objects — and they represent fundamentally different philosophies about where validation belongs. This guide compares them with real code, current GitHub data, and migration advice so you can stop guessing.</p>
