It works much the same way with the benefit that you can take advantage of DigitalOcean's pricing starting from just $5 a month for a droplet. Each droplet can be used to host multiple projects managed using ShiftEdit. Here's a reminder of how to get started:
Click on the Site menu and then Servers
Add a new server with DigitalOcean, you will be prompted to allow write access from ShiftEdit.
Create a new site and select the "Server" tab under "Server type". Alternatively click a repository from those listed on the new tab page.
Save the site and you're done. Your site will be created with it's own unique url.
