How to connect a Render service to Supabase Postgres

Render services connecting to Supabase should generally use the shared connection pooler rather than a direct database connection, because Render lacks outbound IPv6 support and Supabase direct hosts are IPv6-only unless an IPv4 add-on is purchased. Transaction mode on port 6543 suits short web requests, cron jobs, and autoscaled services, while session mode on port 5432 is preferable for long-lived workers or applications requiring session state or prepared statements. Because transaction pooling can route successive transactions to different database sessions, drivers and ORMs must disable server-side prepared statements or statement caching, and Prisma migrations require a separate session-mode connection URL. Connection capacity should be calculated using each service’s maximum instance count multiplied by its per-instance pool size, with transaction clients measured against pooler limits and session or direct connections counted against database limits. Services should be deployed in the Render region nearest the Supabase project to reduce public-network latency, while teams should also monitor Supabase egress costs from query results and consider colocating services and databases if connection constraints, latency, or egress expenses become persistent issues.
