About SheetSandbox
SheetSandbox turns Google Sheets into a database for MVPs and prototypes. You authorize access to a sheet, receive an auto-generated API token for each project, and then read and write rows through simple REST calls or the official Node.js and Python packages. The site says it does not store your data.
It targets waitlists, feedback forms, portfolio contact forms and early-access lists where a full cloud database would be overkill. A Forms feature lets you describe a form in plain English so Claude generates the fields, or start from one of 10 built-in templates, then publish a hosted link whose submissions write into the sheet with no login required. The Node.js package is type-safe with TypeScript support, and the Python package supports async and await.
