Amanda

Amanda is a JSON Schema validator library for Node.js and the browser, supporting JSON Schema Internet Draft v3. It is designed to be universal and extensible, with plans to support other schema formats. Version 1.0.1 is the latest stable release; the library is lightweight, has no dependencies, works with AMD loaders like RequireJS, and is primarily synchronous with callback-based validation. Unlike modern validators like Ajv, Amanda follows older draft specifications and does not support newer JSON Schema versions.
