Cloudron 6.1 released

We are happy to announce the release of Cloudron 6.1!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Cloudron 6.1 includes support for Well-known URIs, multi-domain apps, improvements to File Manager, Netcup DNS & lots of bug fixes!

There is a virtual community meetup and release party on Friday Feb. 12 18:00 CET/UTC+1 (convert to your timezone) at See this forum post for more details.

Well-known support

Well-Known URIs are a mechanism for web protocols to discover policy and information about a host. Apps like Mastodon, Matrix, Pixelfed require Well-Known documents to be setup for federation to work.

In Cloudron 6.1, you can easily setup these URIs in theDomains view. The matrix and mastodon server location can be set per domain and Cloudron will serve up the well-known docs required for those protocols to function.

Well-known docs are also used for auto-configuring the email settings of a domain via autoconfig.xml. Cloudron now automatically serves up this file when Cloudron Email is enabled for the domain. Auto detection in email clients like Thunderbird, K-9, KMail, Evolution, Kontact should work out of the box.

File Manager Improvements


Files can be multi-selected using Ctrl/Cmd + Click. All operations like delete, changing ownership work on multiple files now.

Cut, Copy & Paste

Files can also be be cut or copied into different directories. You can drop files into the breadcumb bar to move it to the correct location.

Upload progress

When uploading files, there is a progress bar which shows the current files upload size and the total size to be uploaded.

Multi-domain apps

Prior to Cloudron 6.1, each app can only have a single domain. With Domain Alias support, a single app can have the ability to be associated with multiple domains.

The alias feature is only enabled for select apps since it requires apps to support multiple domains. We have already enabled this feature for apps EspoCRM, Surfer, Kutt.

To add an additional domain for an app, add an Alias in the Location view.

For example, EspoCRM can now be used to host a customer portal in a custom domain like See our docs on how to set this up.

With this feature, WordPress Multi-site can become a reality on Cloudron. We will release a new version of WordPress that enabled multi-domain support next week.

Netcup DNS

If your domain is registered with Netcup, you can use Cloudron's Netcup DNS backend to manage the DNS. To get started, create an API Key and API Password for the Netcup account in your Customer Control Panel and agree to the ToS. Then, create both an API Key and the API Password.
