# Actix is an Ecosystem of Crates
|
|
|
|
Long ago, `actix-web` was built on top of `actix`, a powerful and fast actor system.
|
|
Now, `actix-web` is largely unrelated to the actor framework and is built using a different system.
|
|
Though `actix` is still maintained, its usefulness as a general tool is diminishing as the
|
|
futures and async/await ecosystem matures. At this time, the use of `actix` is only required for
|
|
WebSocket endpoints.
|
|
|
|
We call `actix-web` a powerful 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
|
|
production.
|
|
|
|
Most importantly: `actix-web` runs on Rust {{< rust-version "actix-web" >}} or later and it works
|
|
with stable releases.
