The Open VSX Registry, a Vendor-Neutral Open Source Alternative to the Visual Studio Marketplace, Gets its Own Working Group at the Eclipse Foundation

Tuesday, June 27, 2023 - 06:30 by Jacob Harris

BRUSSELS, Belgium – June 27, 2023 – The Eclipse Foundation, one of the world’s largest open source software foundations, today announced the formation of the Open VSX Working Group. The mission of the new working group will be to manage and accelerate adoption of the Open VSX Registry, a vendor-neutral, community-supported alternative to the Microsoft Visual Studio Marketplace. 

Built on the Eclipse Open VSX open source project, the Open VSX Registry currently hosts nearly 3,000 extensions from over 1,500 different publishers, with new publishers and extensions being added daily. Since the Open VSX Registry became available in 2021, developers have consumed more than 40M extensions, with downloads now exceeding 2M per month. To manage and facilitate this ongoing growth, management of the Open VSX Registry will now shift from the Eclipse Cloud DevTools Working Group to a new working group, with initial members including Google, Huawei, Posit, Salesforce, Siemens, and STMicroelectronics. 

“The Open VSX Registry has experienced significant momentum at the Eclipse Foundation, so much so that it merits having its own working group for continued evolution and growth,” said Mike Milinkovich, executive director of the Eclipse Foundation. “By creating a vendor-neutral home with a true open source model for these extensions, we can ensure that this marketplace is guided by the community, and not just a single vendor.”

The Open VSX Registry delivers on the industry’s need for a fully open source approach to marketplace technologies for Visual Studio (VS) Code extensions. It increases transparency and flexibility for extension users, publishers, and tool developers, particularly those leveraging cloud-based development tools and IDEs that want to avoid being locked into proprietary models and marketplaces. 

As an open alternative to the Visual Studio Marketplace, the Open VSX Registry offers free access to extensions that can be used with any technology or tool that supports them. These include many open source solutions like Eclipse Che and Eclipse Theia, as well as Salesforce Code Builder, Google Cloud Workstations, Gitpod, SAP Business Application Studio and other applications based on Eclipse projects.

In addition, since the Eclipse Open VSX code itself is open source, any organization can contribute to the registry code and reuse it to create an internally hosted and managed extension registry for their in-house developers to publish and consume VS Code extensions.
