Sanic is a Python web framework and server that prioritizes asynchronous performance using async/await syntax and ASGI compliance.
The framework addresses the need for fast, non-blocking web applications by leveraging Python's async/await capabilities introduced in Python 3.5. It runs as both a standalone web server and a framework for building HTTP APIs, allowing developers to write concurrent code that handles multiple requests efficiently. The tool is ASGI compliant, meaning it can be deployed with alternative ASGI servers beyond its built-in offering.
Sanic suits developers building high-performance HTTP services and APIs who want to use Python's native async syntax without additional abstraction layers. It works well for projects requiring concurrent request handling and rapid development cycles. The framework targets Python 3.10 and later, so adoption requires a reasonably recent Python version.
The project shows substantial real-world adoption, with nearly all open issues originating from external users rather than the core team. Issue responses typically arrive within one to two weeks. The issue tracker is dominated by bug reports, feature requests, and intermediate-level work, reflecting active maintenance focused on stability and incremental improvements.
