The Mattermost web Marketplace supports discovery, installation, and updates of extensions of the Mattermost platform. If you have built a plugin, app, playbook, integration, or tool that helps other users get more from Mattermost, the web Marketplace is a great way to get feedback on your contribution and help make it more popular. Once your submission is accepted to the web Marketplace, Mattermost will also send you swag!
All contributions are eligible following a review from our team. Apps and plugins that have been thoroughly reviewed by Mattermost will be eligible for our in-product Marketplace as well with some additional requirements. Our in-product Marketplace enables customers to install and manage their apps and plugins directly within the product.
Please fill out the information in this form to be reviewed by a member of the Mattermost team.
Every contribution goes through the following checklist before being added to the web Marketplace at mattermost.com/marketplace:
We will also reach out to you to learn more about the integration, your experience developing with Mattermost, and to coordinate postings for social media.
There are additional functional, technical, and security requirements for apps and plugins to be considered for the in-product Marketplace. The additional requirements are documented here: Community plugins in the Marketplace. You can check off these items when you submit your contributions by opening an issue in our in-product Marketplace repository.
Any security issues found in contributions in the web and in-product Marketplace should be reported by email to
firstname.lastname@example.org, or sent directly to a member of the Security team on the Community Server.
If an integration available through the Marketplace contains a medium or greater security issue or bug that blocks or prevents usage for users isn’t fixed within 14 days of being acknowledged, that integration will be removed from the Marketplace, and may be resubmitted to the Marketplace once the issue is resolved. Mattermost reserves the right to take down contributions at any time if a fix for a security issue is not forthcoming, or the issue is critical enough to justify an immediate takedown.
