Further notes

• Platform as a service? Is one needed alongside BaaS? Dokku markets itself as mini heroku, maybe a good one to try first (e.g. Flynn, tsuru, openshift, dokku, cloud foundry)

Supabase vs. Appwrite. What are your experiences? I am building a medium size App, self hosting. Having a rust backend tightly connected to my DB.
