CollabPortals is a SaaS platform for creating branded, permissioned data portals on top of Airtable bases. Admins connect their Airtable account via OAuth, select tables and fields to expose, configure row-level and field-level permissions, and share a portal URL with end users. End users authenticate to the portal and can view, create, edit, and delete records within the permissions set by the admin, without needing Airtable accounts of their own. Portals can be customised with the admin's branding, logo, and domain.
