  • pybind11

    Seamless operability between C++11 and Python

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

    I'm investigating using C++ to build a REST server, and would love to know of people's experiences with Crow-- or whether they would recommend something else as a "medium-level" abstraction C++ web server. As background, I started off experimenting with Python/FastAPI, which is great, but there is too much friction to translate from pybind11-exported C++ objects to the format that FastAPI expects, and, of course, there are inherent performance limitations using Python, which could impact scaling up if the project were to be successful.

  • redpanda

    Redpanda is a streaming data platform for developers. Kafka API compatible. 10x faster. No ZooKeeper. No JVM!

    Project mention: Choosing Between a Streaming Database and a Stream Processing Framework in Python | dev.to | 2024-02-10

    Stream-processing platforms such as Apache Kafka, Apache Pulsar, or Redpanda are specifically engineered to foster event-driven communication in a distributed system and they can be a great choice for developing loosely coupled applications. Stream processing platforms analyze data in motion, offering near-zero latency advantages. For example, consider an alert system for monitoring factory equipment. If a machine's temperature exceeds a certain threshold, a streaming platform can instantly trigger an alert and engineers do timely maintenance.

  • JetBrains Dev Survey

    What’s up with the C++ ecosystem in 2023? JetBrains Developer Ecosystem Survey 2023 has given us many interesting insights. The Embedded (37%) and Games (39%) industries are already working with C++20, developers are incorporating static analysis in their CI, and ChatGPT usage among coders is flourishing.

  • falco

    Cloud Native Runtime Security

    Project mention: Cisco Acquires Splunk | news.ycombinator.com | 2023-09-21


    Like snort, but looks at system calls.

  • service-fabric

    Service Fabric is a distributed systems platform for packaging, deploying, and managing stateless and stateful distributed applications and containers at large scale.

    Project mention: Migrating Service Fabric apps to .NET 6 | dev.to | 2023-04-10

    The first on the list is the entry project .sfproj. They use a non-SDK-style project template with a bunch of .xml files for configuration but with no C# code. They require Fabric.MSBuild nuget to build and package Service Fabric apps. Unfortunately, the dotnet add package command won't update dependencies since they only support and non-SDK-style project template uses the package.config file to manage dependencies.

  • libcds

    A C++ library of Concurrent Data Structures

  • FunctionalPlus

    Functional Programming Library for C++. Write concise and readable C++ code.

    Project mention: Leaving Haskell Behind | news.ycombinator.com | 2023-08-24

    Hoogle is really amazing!

    Inspired by it, I implemented something similar for FunctionalPlus (a functional-programming library for C++): https://www.editgym.com/fplus-api-search/

    I'd love to see more projects taking this path too. :)

  • etl

    Embedded Template Library

    Project mention: Modern C++ Programming Course | news.ycombinator.com | 2023-11-28

    If you can't use the STL because of exceptions: https://www.etlcpp.com/

  • 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.


    Parsing Expression Grammar Template Library

    Project mention: Show HN: Matcheroni, a tiny C++20 header library for building lexers/parsers | news.ycombinator.com | 2023-07-06

    Very cool, and I like the name!

    I'd be interested in reading about how Matcheroni compares with PEGTL and Lexy.


  • sparsehash

    C++ associative containers

  • sparsepp

    A fast, memory efficient hash map for C++

  • Hopscotch map

    C++ implementation of a fast hash map and hash set using hopscotch hashing

  • function2

    Improved and configurable drop-in replacement to std::function that supports move only types, multiple overloads and more

    Project mention: Callbacks in embedded | heapless environment | /r/cpp | 2023-03-31

    Fixed size function wrappers are not only limited and also a waste of space. Use a configurable function wrapper like fu2 with a stack allocator and set small object optimizer capacity to 0.

  • choc

    A collection of header only classes, permissively licensed, to provide basic useful tasks with the bare-minimum of dependencies.

    Project mention: Delay between MIDI Note Off and Note On message | /r/synthdiy | 2023-05-20

    Btw I am also implementing some midi stuff on the rp2040 and I found a nice library, which is easy to use (header only) and has a lot of classes for common audio / Midi problems and saves you the time to implement all the midi stuff by hand: https://github.com/Tracktion/choc

  • think-cell-library

    think-cell core library

    Project mention: Inside boost::concurrent_flat_map | /r/cpp | 2023-07-07

    We at think-cell use that pattern a lot in our library.


    A c++ toolbox of locality-sensitive hashing (LSH), provides several popular LSH algorithms, also support python and matlab.

  • sparsehash-c11

    Experimental C++11 version of sparsehash

  • semver

    Semantic Versioning for modern C++ (by Neargye)

  • Hashmaps

    Various open addressing hashmap algorithms in C++ (by goossaert)

  • dynamic_bitset

    Simple Useful Libraries: C++17/20 header-only dynamic bitset

  • small

    C++ small containers (by alandefreitas)

  • sarus

    OCI-compatible engine to deploy Linux containers on HPC environments.

  • Stroika

    Modern C++ made easy

  • gtl

    Greg's Template Library of useful classes.

    Project mention: Inside boost::concurrent_flat_map | /r/cpp | 2023-07-07

    gtl library author here. Very nice writeup! Reading it made me think, and I believe I know why gtl::parallel_flat_hash_map performs comparatively worse for high-skew scenarios (just pushed a fix in gtl).

  • WorkOS

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