Stackby
No-code spreadsheet-database with forms, automations and AI
What is Stackby?
Stackby is a no-code platform that looks like a spreadsheet and works as a relational database. Tables with more than 30 column types can be viewed as a grid, kanban board, calendar, gallery, list or timeline, and extended with forms, automations, AI columns and connectors that pull data from third-party APIs. It runs in the browser and has apps for Mac, Windows, iOS and Android.
Stackby has a free plan. Paid plans start at $4.2 per user / month for 3 users, billed annually ($149 / year). See every plan
Good for
- Small teams that want a spreadsheet-style database with forms and automations
- Pulling data from third-party APIs into table columns
- Teams of three or more, where annual bundles lower the per-user price
Worth knowing
- Annual prices are sold in team-size bundles (1, 3, 6, 10 users and up), so the per-user rate changes with the seat count.
- Rows are capped per stack: 1,500 on Free, 7,000 on Economy, 50,000 on Business and 100,000 on Pro.
- Table, column and view permissions, personal and locked views and 2FA start at Business; SAML single sign-on is Enterprise only.
- The Free plan refreshes API-connected cells manually and keeps only 2 weeks of activity history.
Key features
- Grid, kanban, calendar and timeline views
- Tables with 30+ column types can be shown as a grid, kanban board, calendar, gallery, list or timeline, with sorting, filtering, grouping and color formatting.
- Form builder
- Drag-and-drop forms write responses straight into tables and support conditional logic, signatures and multiple line items. Custom branded forms start at the Economy plan.
- Automations
- Trigger-and-action workflows send emails and Slack notifications, update rows or generate text with AI. Internal runs are capped at 100 on Free, 1,000 on Economy and 25,000 on Business.
- AI columns with your own API keys
- AI columns call OpenAI, Gemini or Anthropic models using the customer's own API keys to generate content, analyze documents or do web research.
- Column-linked API connectors
- Columns can pull data from third-party APIs: 2 connectors on Free, 10 on Economy and 15 on Business. The Free plan refreshes cells manually; paid plans refresh automatically.
