Table of Contents

What is Open VSX Registry?

The Open VSX Registry offers a community driven, fully open platform for publishing and consuming VS Code extensions. The Registry is built on Eclipse Open VSX, which is an open source project hosted at the Eclipse Foundation.

Open VSX is integrated into multiple software applications that support VS Code extensions. There is strong demand for a fully open alternative to the Visual Studio Marketplace, and with hundreds of great extensions already available, it is the intent of the Eclipse Foundation to enable continued and accelerated growth.

Eclipse Foundation Management

The Open VSX Registry has been transitioned to the Eclipse Foundation and is being managed under the Eclipse Cloud Development (ECD) Tools Working Group in order that all stakeholders can benefit from vendor-neutral, open source operation and governance.  

What do I Need to know as a Consumer of Open VSX?

If you are consuming extensions in applications that use the Open VSX Registry (e.g. in Gitpod or VSCodium) there will be no usage impact. You can expect a seamless experience while we work to add more extensions, raise the visibility of extensions, and increase the number of consumers to ensure the long-term viability and vibrancy of the registry.

What do I Need to Know as a Publisher to Open VSX?

All publishers are required to:

Why do I Need to Sign a Publisher Agreement?

The purpose of the Eclipse Foundation Open VSX Publisher Agreement is to provide a written record that you have the authority to enter into and agree to the terms outlined in the agreement to publish extensions under a license to the Open VSX Registry. 

How Do I Sign the Publisher Agreement?

Publishers can sign the Eclipse Foundation Open VSX Publisher Agreement via their profile page on Open VSX Registry.  

The following steps are required in order to sign the agreement:

What Happens if I do not Sign the Publisher Agreement?

If you choose not to sign the Eclipse Foundation Open VSX Publisher Agreement, you will not be able to publish extensions and any extensions that you have previously published will be deactivated and unavailable to consumers until after you do sign the agreement.

Do I Need to Sign the Eclipse Contributor Agreement in order to Publish Open VSX Extensions?

No, there is no requirement to sign the Eclipse Contributor Agreement. You do, however, need to sign the Eclipse Foundation Open VSX Publisher Agreement.

Can I sign the Publisher Agreement on behalf of a Service Account?

Yes, the Publisher Agreement accounts for this. If you are able to sign the Publisher Agreement based on a service account and related service GitHub ID, coupled with the ability to enter into the Publisher Agreement (necessary rights to do so based on the terms of the Publisher Agreement), then you may do so.

Please note if you wish to publish as an individual at a later time, you will need to create an individual account against a personal GitHub ID and sign the Publisher Agreement with that ID as an individual.


Does my Extension have to be Licensed?

Yes, all extensions must be licensed. Your extension’s license should be expressed by including a license expression in the package.json manifest. If you attempt to publish an extension without a license, you will be given the opportunity to select the MIT license as a default. If you have questions about what license is best for you, we recommend that you read about open source licenses at the Open Source Initiative.

How do I know what License an Extension is Published under?

The applicable licenses of Open VSX Registry extensions are listed on the respective Overview page in the registry and are included in the JSON metadata of each extension.

How do I Publish Extensions?

The publishing process is described in the Open VSX Wiki.

How do I Unpublish an Extension?

Please file an issue with the project and a team member will provide this assistance.

Are Open VSX Registry Extensions Royalty Free?

The Open VSX Registry does not collect fees to publish or consume extensions. All extensions in the Open VSX Registry are made available without fee, subject to the terms of the respective licenses.

How Much is the Open VSX Account Fee?

There are no fees associated with publishing or consuming content from the Open VSX Registry.

How do I Opt Out of Auto-Updates?

Auto-update is a feature of VS Code (or other applications consuming extensions). Please configure the client application accordingly if you wish to disable auto-updates of extensions. Open VSX Registry itself does not provide any auto-update facility.

How do I get Technical Support?

The Open VSX Registry and the Eclipse Foundation cannot provide support for extensions that you have installed from the registry. The individual publishers are responsible for providing support for their own offerings. 

Users can ask questions, search for answers, enter issues and feature requests for the Open VSX Registry itself in the project’s GitHub repository.  

How do I get help with the Publisher Agreement?

Questions related to the Eclipse Foundation Open VSX Publisher Agreement, licenses, privacy, etc. should be sent to
