# Real-time two-way sync between Supabase and Attio

Map fields once for two-way sync. Permitted Supabase row inserts reach Attio, and updates in Attio reach Supabase.

Capabilities

## Everything you need to sync Attio

Connects over REST API, mapped field-by-field into Supabase, with row-level audit and no backend of your own to run.

### Two-way sync

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.

### Live, not batched

Webhooks on record and list-entry events, with polling as a fallback. Stacksync polls efficiently so updates still land in Supabase within moments.

| People | Two-way synced |
| Companies | Two-way synced |
| Custom objects | Two-way synced |

### Every object, standard or custom

Standard objects and custom objects are both fair game. Stacksync's schema discovery maps fields automatically, no manual data dictionary.

Use cases

## What teams ship first

Patterns a two-person team can ship in a week. Any table in Supabase maps to any object in Attio.

Real-time

### Two-way sync

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.

## Why builders sync **Supabase and Attio**

### Ship without a backend

No ETL jobs or sync scripts to maintain. Map Supabase tables to People and Companies once, and every write stays in sync automatically.

### Every write moves both ways

Changes in Supabase reach Attio in real time, and back. people, companies and users stay consistent everywhere they live.

### Built to run in production

Your Supabase write-ahead log is read directly, while Attio changes are picked up instantly, no polling delays or extra load.

How it works

## Four steps, and no backend to maintain

01

### Connect

OAuth your project and the system. Schemas read automatically.

02

### Map

Tables to objects, fields to fields. Transforms run inline.

03

### Sync

Historical backfill, then continuous CDC both ways.

04

### Monitor

Row-level logs, latency and one-click replay.

## Sync Supabase with Attio from React

One client, the same auth as your Supabase project. If you know the Supabase client, you already know this one.

[Read the docs](https://docs.stacksync.com/)

```
import { createClient } from '@stacksync/client'const stacksync = createClient(  process.env.SUPABASE_URL,  process.env.STACKSYNC_API_KEY)export default function Deals() {  const [deals, setDeals] = useState([])  useEffect(() => {    stacksync.from('deals').select('*')      .then(({ data }) => setDeals(data))  }, [])  return <DealList items={deals} />}
```

```
import { createClient } from '@stacksync/client'export async function POST(request) {  const stacksync = createClient(    process.env.SUPABASE_URL,    process.env.STACKSYNC_API_KEY  )  const { id, stage } = await request.json()  // writes Supabase, propagates to Attio  const { data } = await stacksync    .from('deals')    .update({ stage })    .eq('id', id)  return Response.json(data)}
```

```
from stacksync import create_clientstacksync = create_client(    os.environ['SUPABASE_URL'],    os.environ['STACKSYNC_API_KEY'])# one write, both systemsstacksync.table('deals').update(    {'stage': 'won', 'amount': 48000}).eq('id', 'd_10427').execute()for row in stacksync.logs('deals').recent():    print(row['system'], row['latency_ms'])
```

```
import { createClient } from '@stacksync/client'Deno.serve(async (req) => {  const stacksync = createClient(    Deno.env.get('SUPABASE_URL'),    Deno.env.get('STACKSYNC_API_KEY')  )  const { record } = await req.json()  await stacksync.from('accounts').upsert({    id: record.id,    owner: record.owner_email  })  return new Response('ok')})
```

```
// claude_desktop_config.json{  "mcpServers": {    "stacksync": {      "command": "npx",      "args": ["-y", "@stacksync/mcp"],      "env": {        "STACKSYNC_API_KEY": "sk_live_...",        "SUPABASE_URL": "https://xyz.supabase.co"      }    }  }}// your agent now reads and writes// every connected system of record
```

```

FAQ

## Supabase + Attio FAQ

### How does Supabase sync with Attio?

Stacksync watches your Supabase tables via CDC and Attio's API in real time. A permitted write on either side maps to fields on the other, with row-level logs for every change.

### Is the Supabase + Attio sync two-way?

Yes. Changes made in Supabase propagate to Attio and vice versa. Field write controls preserve read-only values within the two-way sync.

### Do I need to write backend code to connect Supabase and Attio?

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.

### Is my Attio and Supabase data secure in transit?

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.
