Why teams connect MySQL and Supabase
Keep MySQL 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 MySQL 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
- Replicate ERP master data (customers, items, pricing) into the MySQL databases behind storefronts and portals
- Keep e-commerce orders in MySQL flowing into finance and fulfillment systems without export scripts
- Mirror billing and subscription records into Supabase tables the application can join directly
- Reflect auth.users state into support and CRM systems so teams see account status without querying the database
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 MySQL and Supabase, so each workload runs on the engine that suits it.
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.
What you can sync between MySQL 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.
| MySQL objects | Supabase objects | |
|---|---|---|
| Triggers An alternative change-capture mechanism when binlog access is unavailable. | Storage Object Metadata File metadata rows that can be joined to synced application data. | |
| Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. | Tables Standard Postgres tables; the primary two-way sync target. | |
| Tables The primary sync target; rows map to records in connected systems. | Views Read-side projections exposed to outbound syncs. | |
| Views Read-side projections used as outbound sync sources. | Schemas Namespaces (public and custom) that scope sync access. | |
| Columns Field-level mapping targets with engine-typed values. | auth.users Managed authentication users, often mirrored into CRM or support systems. | |
| Primary and Unique Keys Match keys for idempotent upserts and conflict handling. | Row Level Security Policies Row-level access rules that govern what the REST layer exposes. |

How the MySQL and Supabase connectors work
MySQL
- Integration surface
- SQL wire protocol (MySQL client/server protocol)
- Authentication
- Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
- Change detection
- Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
- Capabilities
- read · write · CDC
- Rate limits
- No API rate limits; throughput is bounded by connection limits and server resources
Supabase
- Integration surface
- 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
- Change detection
- Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime; database webhooks can also fire on row changes
- Capabilities
- read · write · CDC · webhooks
- Rate limits
- SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits
How it works
How to connect MySQL to Supabase — three steps, no code

FAQ
MySQL and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between MySQL and Supabase: authenticate both systems, choose the objects to sync (such as MySQL's Triggers and Databases (Schemas)), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the MySQL side: Primary and Unique Keys, JSON Columns, Stored Procedures, Triggers, plus custom fields where MySQL exposes them. On the Supabase side: Storage Object Metadata, Tables, Views, Schemas. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 MySQL and Supabase: Regional or environment copies; Cross-engine sync; Migration with zero-downtime cutover. Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
-
MySQL: SQL wire protocol (MySQL client/server protocol). Authentication: Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host). 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.
-
MySQL: INSERT ... ON DUPLICATE KEY UPDATE provides native upsert semantics for idempotent inbound writes. Supabase: Supabase Realtime is built on the Postgres write-ahead log, streaming row changes over websockets. Stacksync's field mapping accounts for these differences between MySQL and Supabase without custom code.
