Why teams connect Render Postgres and Supabase
Keep Render Postgres and Supabase synchronized in real time, across engines, regions, or services, in one or both directions.
Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.
Stacksync syncs tables or collections between Render Postgres and Supabase continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.
Common use cases
- 01 Capture row-level changes via logical replication and propagate them to a warehouse or another database in near real time.
- 02 Serve as the operational read/write store behind internal tools while Stacksync keeps it consistent with SaaS systems of record.
- 03 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
- 04 Sync application tables in Supabase with the CRM two-way so new signups appear as contacts and sales edits flow back to the app
Common sync patterns
Shared reference data between services
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
Regional or environment copies
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
Cross-engine sync
Keep the same dataset live in both Render Postgres and Supabase, so each workload runs on the engine that suits it.
What you can sync between Render Postgres and Supabase
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Render Postgres objects | Supabase objects | How this pairing syncs | |
|---|---|---|---|
| Tables Relational tables with full column typing; synced two-way with CRMs, ERPs, and SaaS apps so application data is queryable as plain Postgres rows. | Tables Standard Postgres tables; the primary two-way sync target. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Views Saved queries exposed as read-only relations; read out to BI tools or downstream syncs without duplicating transformation logic. | Views Read-side projections exposed to outbound syncs. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Schemas Namespaces that organize tables per app or environment; sync targets are scoped per schema to keep synced data isolated and tidy. | Schemas Namespaces (public and custom) that scope sync access. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Materialized Views Precomputed query results refreshed on demand; read for fast reporting tables that downstream systems can consume. | Storage Object Metadata File metadata rows that can be joined to synced application data. | Materialized Views is specific to Render Postgres and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side. | |
| Columns and Types Full Postgres type system including JSONB and arrays; field mappings preserve native types instead of flattening to strings. | auth.users Managed authentication users, often mirrored into CRM or support systems. | Columns and Types is specific to Render Postgres and auth.users to Supabase — each maps to any object or custom field on the other side. | |
| Indexes and Constraints Primary keys, unique constraints, and foreign keys; unique keys drive idempotent upserts and conflict resolution during sync. | Row Level Security Policies Row-level access rules that govern what the REST layer exposes. | Indexes and Constraints is specific to Render Postgres and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side. |
How changes propagate between Render Postgres and Supabase
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Render Postgres Supabase Sub-second propagation
DetectionChanges in Render Postgres are captured at the source via change data capture — no polling loop against its API. Logical replication via WAL and replication slots for change data capture when enabled on the instance, with timestamp or cursor-based polling as the.
DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.
Supabase Render Postgres Sub-second propagation
DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.
DeliveryEach detected change is applied to Render Postgres as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Render Postgres: No API rate limits — throughput is bounded by the instance's plan (CPU, RAM, connection limit); connection pooling is recommended since managed plans cap concurrent connections.
- Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

FAQ
Render Postgres and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Render Postgres and Supabase: authenticate both systems, choose the objects to sync (such as Render Postgres's Tables and Views), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Render Postgres and Supabase: Shared reference data between services; Regional or environment copies; Cross-engine sync. Services that own separate databases stay consistent on the records they share, without a custom replication layer.
-
Render Postgres: PostgreSQL wire protocol (managed Postgres on Render). Authentication: Standard Postgres connection string — host, port, database, user, password with TLS; Render provides internal and external connection URLs and IP allowlisting. Supabase: Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST). Authentication: Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer. Stacksync manages authentication, retries, and rate limits on both sides.
-
Render Postgres: Logical replication requires wal_level=logical and an available replication slot; plan connection limits make pooling important for busy syncs. Supabase: PostgREST auto-generates a REST endpoint per table, with Row Level Security policies gating access at the row level. Stacksync's field mapping accounts for these differences between Render Postgres and Supabase without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Render Postgres and Supabase records are not retained after a sync operation.
