Stacker is a no-code platform for building internal tools and client portals from Airtable or Google Sheets. See pricing, features, and use cases.
Stacker is a no-code platform, founded in 2017 by Sam Davyson and Michael Skelly and based in London, that lets operations teams turn existing spreadsheets and databases into fully functional internal tools, custom CRMs, and client-facing portals. Rather than requiring a fresh data migration, Stacker connects directly to sources like Airtable and Google Sheets so any app built on top of it stays in sync with the underlying records.
The company has raised about 23 million US dollars in funding, including a 20 million US dollar Series A round led by Andreessen Horowitz in 2021, with earlier backing from Y Combinator and Initialized Capital. More recently, Stacker added an AI-driven, prompt-to-app builder that generates a working database and interface from a natural-language description of the app a user wants.
Stacker's core capability is turning a spreadsheet or database connection into a structured app with forms, tables, dashboards, and role-based views, without requiring custom development. Role-based access controls let teams expose different data and permissions to internal staff versus external clients from the same underlying dataset, which makes Stacker popular for client portals as well as internal operations tools. The newer AI builder lets users describe their desired app in plain language and have Stacker scaffold the relational data model and interface automatically, and the platform also supports automations, custom domains, and white-labeled client-facing apps.
Stacker uses a credit-based subscription model. The Standard plan starts at 50 US dollars per month for 250 credits, with higher credit tiers available at 100, 200, 500, 1,000, and 2,000 US dollars per month for progressively larger credit allocations. All Standard-tier plans include unlimited customer portals, white-label branding, custom domains, and access to Stacker's integration library, with no per-seat charges. The Enterprise plan offers custom credit volumes, dedicated onboarding, an SLA with priority support, and single sign-on, and a free trial including 100 US dollars of non-expiring credits is available without a credit card.
