How can our dev team contribute to Coral?#

We are lucky to work with newsroom dev teams and individual contributors who span the world, and come from newsrooms of all sizes. You can read our Contribution Guide to get started, but feel free to reach out to us via GitHub too.

What if we want to add a feature you don't have?#

Coral is open source, so you're free to develop additional functionality and submit a pull request.

Do you have GDPR features?#

Yes! Please read our GDPR documentation for your version for more information and instructions to get started.

Can I import my existing comments?#

Yes! For version 4.x.x we have a community-supported import framework that you can use to migrate your existing comments.

Import tools are still in development for version 5, but will be coming soon! Contact us at if you need an importer for version 5.x.x.

Does Coral enforce unique usernames?#

We don't do this because your SSO should be the single source of truth for all user account management, including usernames. If Coral were to reject or change usernames supplied by the SSO, there would be a conflict, as we only receive from your SSO and don't push changes to your user database.

What support is available?#

You can always email us at, and if we are able to help we will answer your questions. In some cases, we are able to offer paid support packages. You can inquire about this via the support email address above.

Is there a hosted version I can purchase by monthly subscription?#

Yes! Visit our hosting page to submit information and receive a quote.
