Sanic Async Web

Sanic is a Python async web framework for building high-performance web applications and APIs. Unlike Flask (synchronous, handles one request per thread) or Django (heavyweight, batteries-included), Sanic is minimalist and async-native. Sanic uses ASGI (Asynchronous Server Gateway Interface) to handle thousands of concurrent connections with a single process, making it ideal for real-time applications (WebSockets), high-throughput APIs, and microservices. Sanic applications are written with async/await syntax, allowing non-blocking I/O (database queries, HTTP calls) without spawning threads. Middleware, request handlers, and response writing are all async.
