Why can I use "http://localhost:PORT" with CORS in Spaces?

Safari doesn’t respect my wildcard rule in CORS but Firefox and Chrome do. None of the suggestions in this StackOverflow post helped either:

I feel like this could be remedied if Spaces was configured to allow a URL without a TLD.

Thanks for flagging this issue for us. It looks like the input validation in our control panel is a bit too strict here. As a work-around until this experience is improved, you can create CORs configurations for Spaces using the API for origins without a TLD. For example, using s3cmd you can run:

  1. s3cmd setcors cors.xml s3://example-space

Where the contents of the cors.xml file contains your CORs configurations in XML format. For example:

So the year has gone by and it still isn’t possible to set as a cors via the control panel

CORS options are now available thru DigitalOcean Dashboard. If you are facing this problem:

  1. Go to
  2. Select your Space
  3. Go to Settings tab
  4. On “CORS Configurations”, click on the “+” (Plus) button

Create a new configuration with this values:

  • Origin: *
  • Allowed Methods: GET
  • Allowed Headers: Click “Add header” an them: *
  • Save options

Should work.
