uvloop is a fast, drop-in replacement of the built-in asyncio event loop. uvloop is implemented in Cython and uses libuv under the hood. The project documentation can be found here. Please also check out the wiki.

GameNetworkingSockets - Reliable & unreliable messages over UDP

•    C++

The main interface class is named SteamNetworkingSockets, and many files have "steam" in their name. But Steam is not needed. If you don't make games or aren't on Steam, feel free to use this code for whatever purpose you want. The reason for "Steam" in the names is that this provides a subset of the functionality of the API with the same name in the Steamworks SDK. Our main reason for releasing this code is so that developers won't have any hesitation coding to the API in the Steamworks SDK. On Steam, you will link against the Steamworks version, and you can get the additional features there (access to the relay network). And on other platforms, you can use this version, which has the same names for everything, the same semantics, the same behavioural quirks. We want you to take maximum advantage of the features in the Steamworks version, and that won't happen if the Steam code is a weird "wart" that's hidden behind #ifdef STEAM.

snabb - Snabb: Simple and fast packet networking

•    Lua

Snabb (formerly "Snabb Switch") is a simple and fast packet networking toolkit. We are also a grassroots community of programmers and network engineers who help each other to build and deploy new network elements. We care about practical applications and finding simpler ways to do things.

Fuel - The easiest HTTP networking library for Kotlin/Android

•    Kotlin

The easiest HTTP networking library for Kotlin/Android. You can also wait for the response. It returns the same parameters as the async version, but it blocks the thread. It supports all the features of the async version.

Moya - Network abstraction layer written in Swift.

•    Swift

A Chinese version of this document can be found here. You're a smart developer. You probably use Alamofire to abstract away access to URLSession and all those nasty details you don't really care about. But then, like lots of smart developers, you write ad hoc network abstraction layers. They are probably called "APIManager" or "NetworkModel", and they always end in tears.

ZeroTierOne - A Smart Ethernet Switch for Earth

•    C++

ZeroTier is a smart programmable Ethernet switch for planet Earth. It replaces the physical LAN/WAN boundary with a virtual one, allowing devices of any type at any location to be managed as if they all reside in the same cloud region or data center. All traffic is encrypted end-to-end and takes the most direct path available for minimum latency and maximum performance. The goals and design of ZeroTier are inspired by among other things the original Google BeyondCorp paper and the Jericho Forum.
