Disclaimer - I work on Hasura, so I won't comment too much on which is better.
They're all similar flavors of producing realtime results - which take similar, but different, methods to their approach.
My understanding (please feel free to correct me if I'm wrong):
- Supabase Realtime uses WAL.
- Hasura Streaming Subscriptions uses a query which will be append-only (could be a sort-by or also WAL).
- Hasura Live Queries uses interval polling, refetching, and multiplexing.
- Supabase uses Postgres RLS for authorization, while Hasura uses an internal RLS system which composes queries (which allows for features like the multiplexing above).
- All 3 use websockets for their client communication.
