Top 23 C++ Networking Projects

  • Muduo

    Event-driven network library for multi-threaded Linux server in C++11

  • ZeroTier

    A Smart Ethernet Switch for Earth

    • Project mention: Compiling zerotier-cli on Linux Mint 21 | /r/zerotier | 2023-10-26

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • C++ Workflow

    C++ Parallel Computing and Asynchronous Networking Framework

  • cpp-httplib

    A C++ header-only HTTP/HTTPS server and client library

    • Project mention: Experience using crow as web server | /r/cpp | 2023-11-06

    Alternatives at the low to medium level of abstraction include civetweb and mongoose, which have a common ancestor. Both of these appear to be C rather than C++, but seem to be production quality and well-documented. Another C library is cpp-httplib, which is probably too low-level for me.

  • ZeroMQ

    ZeroMQ core engine in C++, implements ZMTP/3.1

    • Project mention: Lightweight and fast AMQP (0-9-1) server | news.ycombinator.com | 2024-04-07

    Slightly OT:

    Are ZeroMQ and NanoMQ still widely used (and recommended)?

    https://github.com/nanomq/nanomq

  • Proxygen

    A collection of C++ HTTP libraries including an easy to use HTTP server.

    • Project mention: Backdoor in upstream xz/liblzma leading to SSH server compromise | news.ycombinator.com | 2024-03-29

    Looking forward to the time when Meta will make https://github.com/facebookincubator/zstrong.git public

    found it mentioned in https://github.com/facebook/proxygen/blob/main/build/fbcode_..., looks like it's going to be cousin of zstd, but maybe for the stronger compression use cases

  • POCO

    The POCO C++ Libraries are powerful cross-platform C++ libraries for building network- and internet-based applications that run on desktop, server, mobile, IoT, and embedded systems.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • GameNetworkingSockets

    Reliable & unreliable messages over UDP. Robust message fragmentation & reassembly. P2P networking / NAT traversal. Encryption.

    • Project mention: How are game servers financed | /r/gamedev | 2023-12-06

    Steam does have a NAT traversal/punchthrough service too. It's apparently usable without Steam according to their README on https://github.com/ValveSoftware/GameNetworkingSockets but honestly the only easy to use implementation I know is in Facepunch.Steamworks which requires a SteamID to initialize

  • C++ REST SDK

    The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services.

    • Project mention: What is the industry standard today in C++ to deploy REST microservices in Kubernetes? | /r/cpp | 2023-09-06

    My favourite was Microsoft's cpprestsdk, but for some reason now is in maintenance mode, I don't know why, so it's hard to suggest it for new projects. A nice alternative is restc-cpp, that's has a good high-level interface, if this is what you want.

  • WebSocket++

    C++ websocket client/server library

  • cpr

    C++ Requests: Curl for People, a spiritual port of Python Requests.

    • Project mention: What C++ library do you wish existed but hasn’t been created yet? | /r/cpp | 2023-07-08

    This one might fit the bill https://github.com/libcpr/cpr

  • nghttp2

    nghttp2 - HTTP/2 C Library and tools

    • Project mention: Nghttp2 1.57.0 – HTTP/2 C Library | news.ycombinator.com | 2023-10-21

  • Boost.Beast

    HTTP and WebSocket built on Boost.Asio in C++11

  • evpp

    A modern C++ network library for developing high performance network services in TCP/UDP/HTTP protocols.

  • PcapPlusPlus

    PcapPlusPlus is a multiplatform C++ library for capturing, parsing and crafting of network packets. It is designed to be efficient, powerful and easy to use. It provides C++ wrappers for the most popular packet processing engines such as libpcap, Npcap, WinPcap, DPDK, AF_XDP and PF_RING.

    • Project mention: PcapPlusPlus v23.09 is out! - C++ library for capturing and analyzing network packets | /r/cpp | 2023-10-01

    It's been a while since our last release (about 10 months) so quite a lot has changed. I'll try to summarize the most important things. You can see the full list of changes in the release notes: https://github.com/seladb/PcapPlusPlus/releases/tag/v23.09

  • cpp-netlib

    The C++ Network Library Project -- cross-platform, standards compliant networking library.

  • Restbed

    Corvusoft's Restbed framework brings asynchronous RESTful functionality to C++14 applications.

  • libquic

    QUIC, a multiplexed stream transport over UDP

  • Silicon

    A high performance, middleware oriented C++14 http web framework please use matt-42/lithium instead (by matt-42)

  • RESTinio

    Cross-platform, efficient, customizable, and robust asynchronous HTTP(S)/WebSocket server C++ library with the right balance between performance and ease of use

    • Project mention: What is the industry standard today in C++ to deploy REST microservices in Kubernetes? | /r/cpp | 2023-09-06

    In my past job, we used https://github.com/Stiffstream/restinio and absolutely loved it. It's not as active but it honestly didn't need much.

  • MongoDB C++ Driver

    C++ Driver for MongoDB

    • Project mention: MongoDB $weeklyUpdate #122 (June 30, 2023): Databricks, Change Streams, & Terraform | dev.to | 2023-06-30

    We're pleased to announce the release of the MongoDB C Driver (libmongoc) 1.24.0 and C++ Driver (mongocxx) 3.8.0 with support for MongoDB 7.0 and a host of new security features. Check out the release notes for more details:

  • copperspice

    Set of cross platform C++ libraries (Core, Gui, Network, Multimedia, SQL, Vulkan, etc)

    • Project mention: Looking for projects to contribute to | /r/cpp | 2023-04-25

    Tangentially, I just listened to an old cppcast about https://www.copperspice.com/, a QT fork with ambitions of being more c++-ey.

  • roc-toolkit

    Real-time audio streaming over the network.

    • Project mention: Finding an open source project to write tests for. | /r/opensource | 2023-10-02
