Updates to Visual Studio Build Tools license for C and C++ Open-Source projects
Visual Studio Build Tools (VSBT) can now be used for compiling open-source C++ dependencies from source without requiring a Visual Studio license, even when you are working for an enterprise on a commercial or closed-source project.
This change expands user rights to the Build Tools and does not limit the existing Visual Studio Community license provisions around Open-Source development. If you already are a developer contributing to OSS projects, you can continue to use Visual Studio and Visual Studio Build Tools together for free, just like before.
New License Benefits
If you are an enterprise developer or developing any closed-source projects, this change now allows you to use Visual Studio Build Tools to compile and build any C++ 3rd party open-source dependencies, without needing a paid Visual Studio license, when you’re not using Visual Studio for active C++ development.
For example, if your Node.js application depends on npm native modules like sqllite3, bufferutil, etc., in order to successfully install these npm packages on Windows, you will need to use Visual Studio Build Tools. Previously, if the application you were developing was not OSS, installing VSBT was permitted only if you had a valid Visual Studio license (e.g., Visual Studio Community or higher). With this new license option, if you do not need the full functionality of Visual Studio for your active development of your project, you have the flexibility to install Visual Studio Build Tools for free.
As noted above, if you and your team need to compile and develop proprietary C++ code with Visual Studio, a Visual Studio license will still be required.

The C++ OSS ecosystem is a vibrant one and you need to look no further than the growing popularity of vcpkg, the multi-platform C++ dependency manager from Microsoft, to see how it is becoming a fundamental building block for an increasing number of projects. We are thrilled to see the adoption of many of these C++ open-source libraries in the Python or node.JS communities as well. We hope these licensing changes will allow for further adoption of these C++ libraries in enterprise environments, where building from source:
- removes friction in securing the supply chain,
- creates a smooth migration path to the latest MSVC versions,
- presents opportunities for further runtime performance optimizations, and
- potentially allows for more active OSS contributions to these libraries
We are actively working to further simplify the acquisition of the MSVC toolchain and all its dependencies, to make it as easy as possible to bootstrap a C++ environment on Windows for C++ developers as well as for other language communities that chose to depend on MSVC toolchain.
