Two-way sync
Changes in Attio 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 Attio, Attio updates land back in Supabase.
Trusted by fast-scaling teams, from YC startups to enterprise platform teams

Connects over REST API, mapped field-by-field into Supabase, with row-level audit and no backend of your own to run.
Every table maps to a Attio object both ways. Insert a row in Supabase and it lands in Attio; update a record there and Supabase reflects it back.
Webhooks on record and list-entry events, with polling as a fallback. Stacksync polls efficiently so updates still land in Supabase within moments.
Standard objects and custom objects are both fair game. Stacksync's schema discovery maps fields automatically, no manual data dictionary.
Patterns a two-person team can ship in a week. Any table in Supabase maps to any object in Attio.
Changes in Attio instantly reflect in Supabase, and back. No stale data, no manual imports.
Sync Attio companies, people, and deals with Supabase, so ops enriches and updates CRM records with SQL.
Write product usage and enrichment data from Supabase into Attio attributes, so GTM teams work from live account signals.
Keep Attio aligned with the billing or ERP data stored in Supabase, on customer records and plan status.
Mirror Attio lists and list entries into Supabase for pipeline reporting beyond the in-app views.
No custom ETL jobs, webhooks, or sync scripts to write and maintain. Map Supabase tables to Attio objects like People and Companies once, and every write stays in sync from there on.
Changes in Supabase reach Attio in real time, and back. people, companies and users stay consistent everywhere they live.
Your Supabase write-ahead log is read directly, and Attio 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 Attio'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 Attio 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.
