# Whalesync

> Whalesync keeps two apps in sync. Records created or changed in one appear in the other, continuously and in
> both directions, with no code to write. It connects databases, spreadsheets and business apps — Postgres,
> Airtable, Notion, HubSpot, Salesforce, Webflow, Google Sheets and more. Syncs can be set up by a person in the
> app, or built and monitored programmatically through the REST API or the MCP server.

**Plans and pricing** (US dollars). Every plan starts with a 7-day free trial, and no credit card is needed to start
one; when the trial ends, syncing pauses until a plan is chosen. There is no free plan, and the Personal, Solo,
Project, Startup, Business and Professional plans are no longer sold. A plan is priced by its records in sync: the
unique rows actively synced between apps. Updates to those records are unlimited, and so are mappings and active
syncs. Every plan includes two-way sync with real-time updates, Live Export and automated monitoring. Yearly billing
is 20% less than monthly.

- Starter: 2,000 records in sync for $40/month or $384/year
- Plus: 5,000 records in sync for $80/month or $768/year; 10,000 for $120 or $1,152; 20,000 for $160 or $1,536; 50,000 for $200 or $1,920
- Pro: 2,000 records in sync for $200/month or $1,920/year; 5,000 for $400 or $3,840; 10,000 for $800 or $7,680; 20,000 for $1,200 or $11,520; 50,000 for $1,600 or $15,360
- More than 50,000 records in sync: up to 1,000,000 on Plus or Pro, through sales ([book a demo](https://calendly.com/cfonger/30min))

**Connectors.** Two-way sync, by the plan that first includes it; each plan includes the connectors of the plans
before it:

- Starter: Airtable, Asana, Framer, Google Sheets, Mailchimp, Memberstack, Notion, Postgres, Sanity, Stripe (one-way), Supabase, Webflow, Wix CMS, WordPress
- Plus: Attio, Close, Copper, HubSpot, Klaviyo, Pipedrive, Zoho CRM
- Pro: Affinity, Salesforce

Live Export keeps a read-only copy of one app's data in another, up to date. It is on every plan with the same
connectors, so an app on the "Live Export from" list below can be copied one way on Starter, even where its
two-way sync needs Plus or Pro.

- Live Export from: Affinity, Attio, Framer, Gong, HubSpot, Intercom, Linear, Pipedrive, QuickBooks, Sanity, Shopify, Stripe, Supabase, Webflow, WordPress, Zoho CRM
- Live Export into: Airtable, Google Sheets, Notion, Supabase
- Live Export only, with no two-way sync on any plan: Gong, Intercom, Linear, QuickBooks, Shopify

browser sign-in.
