Other open source projects similar to OpenAppStack exist. Each of the platforms listed here, like OpenAppStack, provide a suite of open source cloud applications. Each of the platforms, like OpenAppStack, include their own user management dashboard and all of them offer single sign-on (SSO) features.
However there are changes in implementation that make OpenAppStack different from these alternatives. As far as we found, none of the projects listed below will automatically update your applications without you having to push a button, for example.
Sandstorm allows applications to be installed as so called Grains. Each grain is a copy of the complete application made for a specific purpose. For example, a grain for document editor “Etherpad” contains not only the data written in the notepad, but also the Etherpad and database software. If you have two notepads, you also have two copies of the software. With many users, this approach can run into limits.
YunoHost is mostly based on Debian and its package management and user management system. As a result, Yunohost is relatively lightweight. However, another result of this is that it is likely that if one of the applications on your Yunohost contain a security hole, the data of the other applications is compromised as well. This is less likely in OpenAppStack because it separates the environments of applications from each other to seal them off.
All mentioned platforms require applications running on it to be changed in some way, for example to make use of the authentication system. OpenAppStack tries to steer clear of changing the applications it includes. As long as they support OpenID Connect, so you can sign into it, we can usually run the application as-is. In most cases, OpenAppStack will only need one intervention before an update can be pushed to users: it needs to be tested. We want to make sure that an application works together with the platform and other applications before we let you use it. We work towards a fully automated test suite, so even this would not require human intervention.
