Universal Content Rules Validator & Schema Builder

Ensure data integrity and consistency across all your applications with this powerful visual builder. Users can define granular content validation rules beyond basic data types, including custom regex patterns, conditional logic (e.g., 'if field A is X, then field B must be Y'), cross-field comparisons, range constraints, and format checks (e.g., email, URL, UUID). The tool exports these comprehensive validation rules into various developer-friendly formats like JSON Schema, Zod-like objects, or custom JavaScript validation functions. This is ideal for API developers, form builders, data engineers, and anyone needing robust input validation. The free version allows defining and testing up to 3 rule sets. A $1.99 one-time Stripe payment unlocks unlimited rule set creations, all export formats, and the ability to save/load complex schemas.
