FastAPI (MIT) is an API framework based on Python 3.6+ types that generates OpenAPI 3 schemas, including JSON Schemas for all the models declared.makes it easier by providing a number of scripts that can turn JSON Schema files into readable Markdown documentation that is ready for consumption on GitHub or processed using Jekyll or other static site generators.( JSON Schema Tools), draft-04, -06, -07, and Doca extensions (UI forthcoming).php-json-schema-bench - comparative benchmark for JSON-schema PHP validators using JSON-Schema Test Suite and z-schema/JSCK (MIT).json-schema-benchmark - an independent benchmark for Node.js JSON-schema validators based on JSON-Schema Test Suite (MIT).validator-benchmarks - benchmark of Go JSON Schema validators based on official test suite.Powered by JSON.Net server-side validationĬan be used with YAML and many other formats besides JSONīenchmarks that compare at least two implementations supporting draft-06+ may be listed here. Powered by JsonSchema.Net server-side validation Supports multiple schemas and multiple instances client-side validation Python bindings to Rust’s jsonschema crateįast due to compiling schema into a validation tree Great performance thanks to code generation.
