Two-way sync
Changes in MySQL instantly reflect in Supabase, and back. No stale data, no manual imports.
Map the fields once, and every write moves both ways in milliseconds. Supabase row inserts land in MySQL, MySQL updates land back in Supabase.
Trusted by fast-scaling teams, from YC startups to enterprise platform teams

Connects over SQL wire protocol (MySQL client/server protocol), mapped field-by-field into Supabase, with row-level audit and no backend of your own to run.
Every table maps to a MySQL object both ways. Insert a row in Supabase and it lands in MySQL; update a record there and Supabase reflects it back.
Database triggers — Stacksync creates deterministic triggers for internal logging and s…. Changes land in Supabase in milliseconds, not on the next polling cycle.
Any object the API exposes can be mapped into Supabase, with schema discovery doing the field-matching for you.
Patterns a two-person team can ship in a week. Any table in Supabase maps to any object in MySQL.
Changes in MySQL instantly reflect in Supabase, and back. No stale data, no manual imports.
Two-way sync between a MySQL application database and Supabase, so operational records and CRM records stay identical.
Expose Supabase tables as MySQL views so legacy internal tools built on MySQL read live business data.
Replicate ERP master data (customers, items, pricing) from MySQL into the Supabase databases powering newer storefronts and portals.
Feed a single warehouse from both MySQL and Supabase continuously, using binlog-based capture instead of nightly dumps.
No custom ETL jobs, webhooks, or sync scripts to write and maintain. Map Supabase tables to MySQL objects like Databases and Tables once, and every write stays in sync from there on.
Changes in Supabase reach MySQL in real time, and back. databases, tables and views stay consistent everywhere they live.
Your Supabase write-ahead log is read directly, and MySQL changes are picked up the moment they happen, so sync keeps pace with live traffic. No polling delays, rate limits, or extra load on your database.
OAuth your project and the system. Schemas read automatically.
Tables to objects, fields to fields. Transforms run inline.
Historical backfill, then continuous CDC both ways.
Row-level logs, latency and one-click replay.
One client, the same auth as your Supabase project. If you know the Supabase client, you already know this one.

Normally $1,000/mo. Yours at $0 during launch week.
Plus $100 in sync credits on the house. No card, no sales call, the same self-serve start you got with Supabase.

The integration layer is where compliance reviews stall. Row-level audit, residency and DPF certification for US, EU, UK and CH transfers, so procurement is a form, not a quarter.

Connects to your systems your way.
Stacksync watches your Supabase tables via CDC and MySQL's API in real time. A write on either side maps to fields on the other and propagates in milliseconds, with row-level logs for every change.
Yes. Changes made in Supabase propagate to MySQL and vice versa. One-way flows are also supported when a direction should stay read-only.
No. Authenticate both systems, pick objects and fields to map, and enable the sync. Most integrations go live in minutes with no infrastructure to manage.
Stacksync is SOC 2 Type II, ISO 27001, HIPAA, GDPR, CCPA and CSA STAR certified, and holds the EU-US, UK and Swiss Data Privacy Framework (DPF) certification. Data is encrypted in transit, with a zero-persistent-storage architecture: records aren't retained after a sync operation.
