Ajv is a popular JSON Schema validator used for data validation in JavaScript applications. It supports the latest JSON Schema draft compatible with many other validators including tv4, draft-js-validator, and z-schema. Ajv has a small and fast implementation, making it suitable for use in both frontend and backend applications. It also supports asynchronous validation and offers many features for generating custom errors and dialects.

Compared to other validators like tv4 and Z-schema, Ajv offers faster JSON Schema validation by using compiled code instead of uncompiled code during the validation process. Additionally, Ajv supports more JSON Schema features, especially when it comes to asynchronous validation. It is actively maintained and has strong community support.
