I started an interim collection which is now included in the https://0data.app list
These are just the ones I’m aware of. Pull requests welcome:
This is also a request for a Fission apps list app 
Thanks @rosano
Right now I think such an app list should be opt in, and that certain minimal information is filled in. Will probably be manual for a while.
We’re look at PWA manifest files to model the information, so the schema looks something like:
- name
- domain
- description
- owner username — don’t know how useful this — there aren’t profiles to link to. So might need author / creator separately
