>Given new entrants into the backend space, like Supabase (for a Firebase-like open source alternative), Hasura (open source GraphQL on Postgres), etc, how viable is Django and similar technologies like Rails these days? It seems like the former are PaaS which you can simply drop into your app but the latter are more so full on backends that let you control everything. How viable? More viable than the newer systems you mentioned, clearly.
