Stacker Review
A no-code app builder that turns Airtable and Google Sheets into secure, branded client portals with granular row-level access permissions.
Is Stacker Worth It?
Stacker is worth it for businesses that already run on Airtable or Google Sheets but need to safely share specific records with external clients. Row-level security permissions and real-time bi-directional sync turn a spreadsheet into a genuinely usable branded portal in minutes, no backend coding required. There’s no permanent free tier, and the rigid UI component system limits how far you can push the aesthetics.
About Stacker
Stacker is a no-code app builder that automates the creation of client portals, internal CRM tools, and custom dashboards directly from existing databases. It targets operations teams and agencies building secure web apps without hiring developers, via a drag-and-drop interface and deep Airtable/Google Sheets integration.
Stacker maps complex database relationships into visual application interfaces automatically, syncing bi-directionally in real time with the underlying database. Row-level security permissions ensure clients see only relevant data, an action-button system triggers Zapier workflows from inside the app, and custom domains support a fully white-labeled deployment.
Is Stacker safe for client data?
Stacker is safe, encrypting data in transit between the frontend and database, storing authentication credentials securely, and enforcing strict role-based access rules to prevent unauthorized data exposure.
