channels vs tornado
Django async support and Python networking compared
channels extends Django with asynchronous protocols and workflows, while tornado combines a Python web framework with an asynchronous networking library. The main distinction is that channels adds async capabilities to Django, whereas tornado provides its own web and connection-handling tools.
channels: Add WebSockets and Async Support to Django
Django Channels extends Django with WebSockets, long-poll HTTP, and task offloading through ASGI. It suits Django teams building interactive or asynchronous features while keeping familiar Django patterns.
tornado: Build Python Web Apps and Async Network Services
Tornado is a Python web framework and asynchronous networking library for services that need to handle long-lived connections. It suits teams building WebSocket or long-polling applications, but its recent development is concentrated among a small number of contributors.

Key differences
- channels is a Django extension; tornado is a Python web framework and networking library.
- channels follows Django-inspired patterns and supports customizing the framework for additional protocols; tornado provides request handlers and URL routes for web endpoints.
- channels lists WebSockets, long-poll HTTP, and task offloading; tornado emphasizes non-blocking I/O for many open connections, including WebSockets and long polling.
- channels uses the BSD-3-Clause license; tornado uses the Apache-2.0 license.
- channels describes maintenance as best-effort, with guaranteed time dedicated to security fixes; tornado's supplied considerations focus on when its asynchronous model is useful.
Choose channels if you…
- need to add asynchronous protocols or task offloading to a Django application.
- want to use Django-inspired patterns for WebSockets or long-poll HTTP.
- need a framework that can be customized for additional protocols.
Choose tornado if you…
- want a Python web framework and networking library in one project.
- need non-blocking I/O for many long-lived connections.
- want to define web endpoints with request handlers and URL routes alongside asynchronous networking tasks.
