-
Event driven architecture. (non-blocking network I/O)
-
Usable as Web server and Application server.
-
Lightweight and fast.
-
Since fly as a server by itself, there is no need to prepare a WSGI server or ASGI server.
fly currently supports the following platforms.

Why fly ?
Interface of fly is as simple as possible. Extracted only the necessary parts as Web framework by referring to various Python web frameworks.
But, a core part of fly is implemented by C language, you can't think of it as Python Web framework.
So, if you're looking for flexible and fast Web framework, should use fly.
How fast ?
look at the result of benchmark.
