# Libwebsockets
|
||
|
|
|
||
|
|
Libwebsockets is a simple-to-use, MIT-license, pure C library providing client and server
|
||
|
|
for **http/1**, **http/2**, **websockets**, **MQTT** and other protocols in a security-minded,
|
||
|
|
lightweight, configurable, scalable and flexible way. It's easy to build and
|
||
|
|
cross-build via cmake and is suitable for tasks from embedded RTOS through mass
|
||
|
|
cloud serving.
|
||
|
|
|
||
|
|
It supports a lot of lightweight ancilliary implementations for things like JSON,
|
||
|
|
CBOR, JOSE, COSE, and supports OpenSSL and MbedTLS v2 and v3 out of the box for everything.
|
||
|
|
It's very gregarious when it comes to event loop sharing, supporting libuv, libevent, libev,
|
||
|
|
sdevent, glib and uloop, as well as custom event libs.
|
||
|
|
|
||
|
|
[100+ independent minimal examples](https://libwebsockets.org/git/libwebsockets/tree/minimal-examples) for various scenarios, CC0-licensed
|
||
|
|
(public domain) for cut-and-paste, allow you to get started quickly.
|
||
|
|
|
||
|
|
[There are a lot of READMEs](https://libwebsockets.org/git/libwebsockets/tree/READMEs) on a variety of topics.
|
||
|
|
|
||
|
|
[We do a huge amount of CI testing per push](https://libwebsockets.org/sai/), currently 582 builds on 30 platforms.
|
||
|
|
[You can see the lws CI rack and read about how lws-based Sai is used to coordinate all the testing](https://warmcat.com/2021/08/21/Sai-CI.html).

## Lws work retrospective
|
||
|
|
|
||
|
|
The initial commit for lws will have been 11 years ago come Oct 28 2021, it's been a lot of work.
|
||
|
|
There are a total of 4.3K patches, touching 800KLOC cumulatively (this is not the size in the
|
||
|
|
repo, but over the years, how many source lines were changed by patches).
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Gratifyingly, it turns out over the years, ~15% of that was contributed by 404 contributors: that's not so bad.
|
||
|
|
Thanks a lot to everyone who has provided patches.
|
||
|
|
|
||
|
|
Today at least tens of millions of devices and product features rely on lws to
|
||
|
|
handle their communications including several from FAANG; Google now include lws
|
||
|
|
as part of Android sources.
