Using the web interface

In Rahti, you run all applications inside projects. Any logged-in user can create a project. Each project has its own private network and is separate from other projects. You can only see the projects you created or that someone shared with you. All your containers, volumes, and other resources live inside a project.

After your access is approved, it may take a while before you can log in.

You can run applications in two ways:
