Why teams connect Google AlloyDB and Supabase
Keep Google AlloyDB 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 Google AlloyDB 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 Migrate workloads from self-managed Postgres while keeping existing syncs pointed at a compatible endpoint.
- 02 Mirror CRM objects into AlloyDB tables so product and internal tools query customer data with plain SQL.
- 03 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
- 04 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
Common sync patterns
Migration with zero-downtime cutover
When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
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.
What you can sync between Google AlloyDB 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.
| Google AlloyDB objects | Supabase objects | How this pairing syncs | |
|---|---|---|---|
| Schemas Namespaces used to separate synced SaaS data from application tables. | 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. | |
| Tables Primary read/write target for bi-directional sync with CRMs and other systems. | 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 Curated projections used as read-only sync sources. | 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. | |
| Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. | Database Functions Postgres functions that can transform or validate synced rows. | Materialized Views is specific to Google AlloyDB and Database Functions to Supabase — each maps to any object or custom field on the other side. | |
| Indexes Keep sync key lookups fast on high-volume tables. | Storage Object Metadata File metadata rows that can be joined to synced application data. | Indexes is specific to Google AlloyDB and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side. | |
| Sequences ID generation relevant when external systems insert rows. | auth.users Managed authentication users, often mirrored into CRM or support systems. | Sequences is specific to Google AlloyDB and auth.users to Supabase — each maps to any object or custom field on the other side. |
How changes propagate between Google AlloyDB 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.
Google AlloyDB Supabase Sub-second propagation
DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.
DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.
Supabase Google AlloyDB 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 Google AlloyDB as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Google AlloyDB: No API-style rate limits; throughput is bounded by instance size.
- Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

FAQ
Google AlloyDB and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Google AlloyDB and Supabase: authenticate both systems, choose the objects to sync (such as Google AlloyDB's Schemas and Tables), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Google AlloyDB: IAM database authentication lets connections use Google Cloud identities instead of static passwords. Supabase: Every Supabase project is a full PostgreSQL database, so standard Postgres drivers, SQL tooling, and log-based CDC apply directly. Stacksync's field mapping accounts for these differences between Google AlloyDB 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 Google AlloyDB and Supabase records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Google AlloyDB and Supabase connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Google AlloyDB–Supabase integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Google AlloyDB and Supabase. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Google AlloyDB: Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback. On Supabase: Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime; database webhooks can also fire on row changes. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
