revalidator

A cross-browser / Node.js validator with JSON Schema compatibility (draft-zyp-json-schema-04). Current stable version is 0.3.1, last released in 2015, no longer actively maintained. It provides a simple `validate(obj, schema)` function that returns `valid` boolean and `errors` array. Key differentiator is lightweight footprint and support for both Node.js and browser environments, but lacks modern JSON Schema features and complete format validation.
