Affordable reverse ETL for real-time, two-way app synchronization.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Whalesync is a web-based cloud data synchronization platform for operators, revenue operations teams, and businesses connecting spreadsheets, databases, CMSs, and CRM systems. It supports reverse ETL workflows such as syncing Postgres data into Salesforce, while also handling two-way synchronization between connected applications. The product is aimed at teams that need operational data to stay current without requiring code or a dedicated data engineering team.
Pricing starts at $40 per month for the Starter plan, which includes two-way sync, real-time updates, Live Export, automated monitoring, and email support. Whalesync offers a 7-day trial without a credit card, and syncing pauses when the trial ends until a plan is selected. Plus adds email and chat support along with Attio, HubSpot, and Pipedrive connectors. Pro includes all connectors and priority support. The plan structure suits teams that value real-time synchronization and need a clear entry point, although transformation support remains basic.
Its standout capability is operational control over synchronized data: visual table and field mapping, historical sync, advanced filters, live export, monitoring, issue alerts, and automatic API handling with retries are included among the key features. Integrations span tools such as Airtable, Google Sheets, Notion, HubSpot, Salesforce, Postgres, QuickBooks, and Pipedrive. Whalesync is a strong fit for teams that need affordable, real-time, two-way synchronization across business apps. Teams requiring deeper transformations or a broader destination connector range should consider an alternative built around more advanced data modeling.
