Falcon
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 specification compliance, and the management of request and response metadata. The project also includes command-line tools to inspect application configuration and routes, alongside utilities for measuring API performance.
