Top 23 C Networking Projects
-
libcurl
A command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features
Verify using curl: curl "http://localhost:/graphql?query=%7B+sysInfo+%7D"
-
If you want real non-blocking IO, the C standard library doesn't support this and the OS-specific APIs tend to be difficult to use (and non-portable), so I would recommend something like libuv.
-
Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

Project mention: How feasible is this idea? Creating a battery run audio transmitter and receiver over TCP/IP | reddit.com/r/esp8266 | 2021-05-30
I'd consider KCP protocol over TCP, it has 30-40% lower latency at the expense of 20% higher bandwidth.

Project mention: Looking for low footprint c++ library to build a REST client | reddit.com/r/cpp | 2021-12-23
-
Another option is to use Mongoose. I've got some personal gripes with it but that aside it's a great library. I've implemented a few different WebSocket interfaces with it.
-
cjdns
An encrypted IPv6 network using public-key cryptography for address allocation and a distributed hash table for routing.
I was really excited for a moment, because I thought this was cjdns https://github.com/cjdelisle/cjdns.

Libwebsockets a powerful and lightweight pure C library\ (48 comments)

cute_headers
Collection of cross-platform one-file C/C++ libraries with no dependencies, primarily used for games
The verdict for indie developers (not using Unity/Unreal) seems: just bite the bullet and buy FMOD (or Wwise or any of the popular proprietary audio engies).
I was actually searching for a good open-source audio library to use, and found out that my options aren't that good. SoLoud is a pain in the ass to install and integrate into an existing codebase, and OpenAL doesn't have any good implementations available (either proprietary or LGPL). I'm now just using a simple single-header audio library in cute_headers (https://github.com/RandyGaul/cute_headers/blob/master/cute_s...), but will probably switch to MiniAudio once the high-level API is finished (https://github.com/mackron/miniaudio/issues/196)

You may not be there yet with your developer skills but if you are curious you can have a look at the netcode source code. I'm not sure if they're still using it since the switch to Lumberyard and Amazon Services but it's a really good and strong codebase: https://github.com/networkprotocol/netcode

libonion - HTTP server library, designed to be easy to use. Apache-2.0
-
facil.io - Mini-framework for web applications. Includes a fast HTTP and Websocket server, and also supports custom protocols. MIT
-
https://github.com/miniupnp/miniupnp/issues/413 is closed. So I’m not sure if the problem exists there still or where?

shadow
Shadow is a discrete-event network simulator that directly executes real application code, enabling you to simulate distributed systems with thousands of network-connected processes in realistic and scalable private network experiments using your laptop, desktop, or server running Linux. (by shadow)
Project mention: Shadow Simlulator – run real applications over a simulated Internet topology | news.ycombinator.com | 2021-04-19For anyone interested in following current development on Shadow, we've been publishing a series of updates. Most recent: https://github.com/shadow/shadow/discussions/1274
The previous update has links back to the whole series; I stopped including it in the most-recent update since it was getting a bit cumbersome: https://github.com/shadow/shadow/discussions/1060

netsniff-ng - Swiss army knife for network sniffing.
-
felix
Project Calico's per-host agent Felix, responsible for programming routes and security policy.
Project mention: Pod-to-pod encryption with Calico and Wireguard - where can I read up on this? | reddit.com/r/WireGuard | 2021-10-05Yes, inter-node–the definitive source is in the felix repo, e.g., https://github.com/projectcalico/felix/blob/master/wireguard/wireguard.go

nope.c
WAFer is a C language-based software platform for scalable server-side and networking applications. Think node.js for C programmers.
