The framework includes capabilities for validating API schemas to identify structural mistakes and auditing incoming and outgoing web traffic agai

go-restful is a framework for building RESTful web services in Go. It functions as a toolkit for managing API endpoints, providing a request router that maps incoming HTTP requests to handler functions using path parameters and custom URL patterns. The framework includes a data conversion layer that transforms Go structures into JSON or XML formats for request and response bodies. It also provides a system for organizing related web services into containers to manage endpoint prefixing and shared configuration. The project covers request lifecycle management through middleware filters for va

PostgREST is a standalone web server that automatically transforms a PostgreSQL database into a RESTful API. It serves as an API gateway that translates HTTP requests into SQL queries, mapping the database schema directly to endpoints without the need for manual route definitions. The system utilizes a JWT authentication layer to validate user identities and map incoming web requests to specific database roles. This allows the server to delegate authorization and permission enforcement to the internal PostgreSQL role system. It includes a generator for OpenAPI specifications to provide stand

Falcon is a minimalist Python web API framework and high-performance microservices framework. It serves as a resource-oriented API toolkit designed for building RESTful APIs and data plane services that prioritize low overhead, reliability, and scale. The framework implements an ASGI web server interface to handle both synchronous and asynchronous HTTP requests and WebSockets. It features a dedicated HTTP middleware system for intercepting network traffic and executing shared processing logic across multiple API endpoints. Its capability surface covers resource-based routing, HTTP specificat

Restify is a Node.js web framework designed for building scalable RESTful web services and APIs. It provides a server-side environment for creating HTTP network services with integrated routing and request handling. The framework utilizes a middleware-based architecture to process incoming requests and manage responses. This approach supports the construction of web interfaces that follow standard architectural principles to deliver data to clients. The system covers a broad range of backend engineering capabilities, including route-based request dispatching, schema-based request validation,

A REST framework for quickly writing resource based services in Golang.

Sanic is a Python ASGI web framework and asynchronous HTTP server. It is designed to build high-performance web applications and servers that handle concurrent requests using non-blocking logic. The framework implements the Asynchronous Server Gateway Interface standard, allowing applications to be deployed across various ASGI-compatible servers. It utilizes an asyncio-based event loop and integrates a Cython-based runtime wrapper around libuv to manage I/O operations. The system manages traffic through route-based request dispatching and a middleware-based request pipeline. These components

Django Tastypie is a framework for building RESTful web services that map Django models to API resources. It functions as a model-based API generator, automatically creating read-write endpoints for database models to enable standard CRUD operations via HTTP. The project serves as a multi-format data serializer and hypermedia API mapper. It converts database data into various response formats, including JSON, XML, and YAML, based on client requests, and transforms database relationships into navigable links for resource discovery. The toolkit includes a security implementation for user authe

This is a framework for building standardized RESTful APIs within Laravel and Lumen applications. It provides a structured environment for developing web services with integrated routing, request handling, and versioning. The project distinguishes itself through a multi-adapter authentication system that validates identities via various schemes and third-party providers.
