The best AI to build an internal tool on top of a spreadsheet
Softr is the best front end for data you already keep in Airtable or Sheets, and it starts at $19/mo billed annually with your own domain included. Glide suits phone-shaped apps and has a generous free plan of 25K rows, but its custom domain costs $199/mo. Base44 is the pick when the tool needs custom logic and you want the source code.

- 02 Glide: Internal mobile-shaped apps over spreadsheet data
- 03 Base44: Getting a real app on your own domain cheaply
