# Actix is an ecosystem of crates

Actix is a few things. The base of it is a powerful actor system for Rust on top of which the
|
|
|
|
|
`actix-web` system was originally built. This is what you are most likely going to work with. What
|
|
|
|
|
`actix-web` gives you is a powerful and very fast web development framework.
|
|
|
|
|
|
|
|
|
|
We call `actix-web` a small and pragmatic framework. For all intents and purposes it's a
|
|
|
|
|
micro-framework with a few twists. If you are already a Rust programmer you will probably find
|
|
|
|
|
yourself at home quickly, but even if you are coming from another programming language you should
|
|
|
|
|
find `actix-web` easy to pick up.
|
|
|
|
|
|
|
|
|
|
An application developed with `actix-web` will expose an HTTP server contained within a native
|
|
|
|
|
executable. You can either put this behind another HTTP server like nginx or serve it up as-is. Even
|
|
|
|
|
in the complete absence of another HTTP server `actix-web` is powerful enough to provide HTTP/1 and
|
|
|
|
|
HTTP/2 support as well as TLS (HTTPS). This makes it useful for building small services ready for
|

|
|
|
distribution.

|
|
|
Most importantly: `actix-web` runs on Rust {{< rust-version "actix-web" >}} or later and it works
|
|
|
|
|
with stable releases.
