Softr

Softr is a no-code platform specialized in building client-facing portals, directories, marketplaces, and simple web apps directly on top of an Airtable base (or Google Sheets), positioning itself as the "frontend layer" that pairs with Airtable's "backend/database layer" — a very common combination in the no-code stacking pattern where Airtable stores and structures the data, and Softr builds the actual user-facing web experience around it. Why it matters: Softr addresses a specific, common gap — teams that have already built a solid Airtable base (a project tracker, a client database, a course catalog) but need a polished, permission-controlled, public or client-facing interface around it, without wanting to migrate that data into a heavier full app builder like Bubble or rebuild the data layer from scratch. It's particularly popular for building client portals (each client logs in and sees only their own projects/invoices/deliverables, pulled live from a shared Airtable base) and internal or membership-gated directories (an alumni network, a vendor marketplace, a course platform) where the primary need is a clean, permission-aware read/write interface over structured data, not deep custom application logic. How it works: Softr connects to an Airtable base (or Google Sheet) as its data source and offers pre-built "blocks" — pattern templates for common page types (a list/grid of records, a detail page, a signup/login form, a user dashboard) — that a builder assembles and styles visually. Its User Accounts and Membership feature layers authentication and record-level permissions on top of the connected data source (e.g., "a logged-in user can only see Airtable rows where the 'Client Email' field matches their login email"), turning a shared spreadsheet-database into a properly access-controlled multi-tenant portal without writing authentication code. Worked example — a client portal built in Softr on top of an Airtable "Projects" base: the Airtable base has a Projects table with fields Client Email, Project Name, Status, and Deliverables (file attachments); Softr's User Accounts feature is configured so that when a client logs in, Softr automatically filters the Projects list block to show only rows where Client Email matches the logged-in user's email; the client sees a clean dashboard of their own projects and can download deliverables directly, while the agency team continues managing all projects for all clients from the familiar Airtable grid interface — the same underlying data, two very different interfaces for two very different audiences, with zero custom authentication or authorization code written.
