| Branch with production data | Yes, by restoring a snapshot or point in time to a new instance | Yes, by restoring a backup to a branch | Needs the PITR add-on |
| Bottom line | From its public pages, RDS for PostgreSQL includes the most recovery and compliance here at a low listed price, all self-serve. The bill has more lines to estimate than the others, and there is no permanent free plan. | From its public pages, PlanetScale lists the lowest price for our scenario and the most compliance on its entry plan, with backups and PITR included. There is no free plan, and its Postgres branches are separate databases rather than copies. | From its public pages, Supabase gives the most around the database: auth, storage and APIs with daily backups for $25. For a database alone, PITR as a flat add-on and per-hour branches make it the highest-priced of the three in our scenario. |
