Whalesync

What it is

Whalesync is a two-way data sync tool. It connects apps such as Salesforce, Airtable, Postgres, Notion, Google Sheets, Webflow and Stripe, and keeps their records matched in both directions. The company's home page puts the pitch in a sentence: "Unlike brittle step-by-step automation tools, Whalesync lets you build deep 2-way syncs between apps." It is for people who run part of their business out of a spreadsheet-style database such as Airtable or Notion and need that data to appear in a website, a CRM or a Postgres table without copying it by hand, and it also has an enterprise page with SOC 2 Type II and SSO.

What you build and how

What you build is a "sync", which the FAQ defines as "a connection between two apps, like Airtable and Webflow." One sync covers as many tables and fields as you like, and you map the fields you care about between the two sides. The home page's line is "Simply map your data and we handle the logic to keep updates flowing." When you turn a sync on, Whalesync continuously syncs data between the apps.

The company draws a sharp line between sync and automation. It describes automation tools such as Zapier or Workato as "if-this-then-that" building blocks you chain together, for example "when a user submits a form, send a message to Slack", and sync as a "deep, bi-directional connection" where all of your data across multiple apps is kept consistent. The site has a Whalesync vs Zapier page and a versus page for Unito. In this directory it sits under workflow automation because it replaces many of the trigger chains teams would otherwise build, but it is a data-consistency tool rather than a step-by-step flow builder.

Each table mapping takes filters, "so only records that match them sync." You can change filters on a sync that is already running; Whalesync pauses it, previews how many records will start and stop syncing, and re-runs the initial sync with the new rules. The FAQ stresses that narrowing a filter never deletes anything: records that stop matching simply stop syncing. Deletes are handled as ordinary changes, and "for new syncs delete approvals are on by default", so a removed record is held until you approve it.

Timing depends on the app. "Live" means changes sync as soon as Whalesync hears about them: where an app supports webhooks that is moments after the change, and where it does not, Whalesync scans on a schedule and picks changes up on the next pass. Every plan syncs at the same speed. Each connection defaults to the fastest frequency its app supports, and you can slow it down to save API quota but not push it past the default.

When data cannot sync, for example a required field is missing, Whalesync alerts you on an Issues page with the exact error from your destination. The site says it supports multi-reference fields and rich text, and it can match existing records across systems when you set up an initial sync, such as matching customers on email address, so you do not start with duplicates.

The connector directory is where the Airtable and Notion shelf comes in. Its entries describe two-way sync of Apollo contacts and accounts with Airtable or Notion. Others are marked "Coming soon" and ask for early access: Bubble's database with Airtable, Postgres and more; ClickUp with Airtable, Notion or Google Sheets; Miro board data with Airtable and Notion; and Microsoft Dynamics 365 Sales with Airtable. There is also a Wix CMS connector page, and the pricing FAQ uses syncing rows from Airtable to Webflow as its example. The company also publishes a post on Contentful alternatives that includes a "no-CMS" option, meaning content kept in a spreadsheet or document tool and synced to the website.

The navigation also lists Docs, a Changelog, Template Packs, Community Tutorials and a Partners page, so there is starter material beyond the connector pages.

The evidence from the pages

Plans start at $40 a month, according to the FAQ, and the plans named there are Starter, Plus and Pro. Starter includes 10 users, while Plus and Pro include unlimited users. "Every plan starts with a 7-day free trial, and no credit card is required to start it. When the trial ends, syncing pauses until you pick a plan." There is no free plan described on the pages held.

Billing works as follows. Yearly plans cost 20% less than paying monthly and are billed once a year, up front. You can upgrade at any time and pay only the difference for the rest of your year, but you cannot downgrade or switch to monthly billing until the year is up, and a canceled plan stays active until the year you paid for ends. If you pause your subscription, syncing stops but all of your sync configurations are kept. The FAQ also answers a nonprofit discount question with "Absolutely!"

Usage is counted in records, not tasks. The pricing page says "when a record syncs for the first time it becomes a record in sync", and "if you sync 10 rows from Airtable to Webflow, you will have 10 records in sync." It does not double-count records across the two apps. In its words, "unlike other automation tools that count updates or tasks, Whalesync allows unlimited updates." The per-plan record allowances are not in the passages held.

The enterprise page lists "SOC 2 Type II certified", "GDPR compliant", "SSO" and "Top rated on G2", and describes encrypted data at rest, with a link to a Whalesync Trust Center. It shows customer features, including a Webflow one that "synced 30k+ records for real-time event reporting."

Who it suits and who it does not

Whalesync suits a small team that treats Airtable, Notion or Google Sheets as its working database and wants a website, CRM or Postgres table to mirror it. A marketer editing content in Airtable and publishing to Webflow, or an ops lead keeping Salesforce and Airtable matched, is the clearest example. The record-based pricing also appeals where the same rows change many times a day.

It is not a workflow builder. If you want branching logic, notifications and multi-step actions across many apps, the company's own comparison assigns that kind of one-way, triggered action to automation tools. The connector list is also finite: several apps, including Bubble, ClickUp, Miro and Dynamics 365 Sales, are marked coming soon, so check that your two apps are live before you plan around it. Finally, speed depends on the source app, since apps without webhooks are scanned on a schedule rather than updated the instant something changes.
