Top 23 SDK Open-Source Projects

  • openapi-generator

    OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)

    Project mention: Show HN: Manage on-prem servers from my smartphone | | 2024-03-27

    Of course you can compile the server from source if you have Go and the OpenAPI generator JAR (

    Follow these steps :

    And then :

    (cd ./impl/http-server-go && GOARCH=amd64 GOOS=openbsd go build -o /app/rebootx-on-prem-http-server-go-openbsd-amd64 -v)

    By adapting the arch if needed. Not tested, but it should work.

  • plasmo

    🧩 The Browser Extension Framework

    Project mention: Show HN: Bedframe – open-source Browser Extension Development framework | | 2023-09-05

    Ooof!! It is an... interesting time right now in extensions land. The switch from MV2 to MV3 is a bit chaotic but hopefully tools like this (Bedframe) and tools like [Plasmo]( start to inject some freshness in the space.

  • WorkOS

  • C++ REST SDK

    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.

  • Bot Builder SDK

  • librealsense

    The all-batteries-included GitHub SDK for Browsers, Node.js, and Deno.

    Project mention: Creating an Automated Profile README using Nodejs and GitHub Actions | | 2024-02-26

    You can fetch different kinds of data with GitHub's API. There are two options: use the API directly or the Octokit.js library (this is the route GitHub recommends). I decided to use the API directly since the Octokit.js library included extra stuff I wouldn't need, which is an overkill for this use case.

  • openvr

    OpenVR SDK

    Project mention: How can I use C++ libraries/SDKs? | /r/Cplusplus | 2023-06-07

    I have been using C++ for a while but never really touched on using a full on SDK and now I want to use this SDK from Valve but my issue is that it isn't clear to me how to use it. What I mean by this is that it comes with a lot of subdirectories and extra stuff but how can I make a hello world program and able to call functions from the header file included in this SDK? I have used .h files before so I understand how the linker and all that works but with such a robust SDK I am not getting how this works on VSCode or maybe that I shouldn't even be using VSCode?
