Map fields once; writes propagate both ways in milliseconds." canonical: https://www.stacksync.com/supabase last_modified: 2026-07-29 --- # Real-time two-way sync between Supabase and your CRM, ERP and data warehouse You built the product on Supabase to move fast. Do the same for Salesforce, NetSuite and Stripe: map the fields once, and every write moves both ways in milliseconds.

Now it writes to the business. If Claude Code, Cursor or an edge function can run one UPDATE, it can close a deal in Salesforce. Same auth, same RLS, same audit trail, no SDK or MCP tool per system.

Any table in Supabase maps to any object in any connector. ### Build internal tools on external system data One GDPR erasure cascades to every downstream system, with a row-level receipt for the auditor. ### CRM and DB sync Closed-won seats and limits land in Supabase, so RLS enforces entitlements without a sync script. ### Real-time ERP visibility inside your database Usage meters, Stripe invoices and data warehouse revrec stay aligned, and any drift is audit-visible. ### Database replication Ship an integrations tab to your tenants. Per-tenant credentials on top of RLS, no second vendor. [How embedded sync works](https://www.stacksync.com/embedded-sync) ### Enrich your CRM from your database Churn, LTV and embeddings computed in the data warehouse, served from Supabase. pgvector can query them live. ### PLG to sales handoff Push activation and seat counts into CRM properties. Pull deal stage and tier back to gate features behind RLS. Pricing ## Free for Supabase builders Normally $1,000/mo. Yours at $0 during launch week.
