formLimiter automatically sets Google Forms to stop accepting responses after a maximum number of responses, at a specific date and time, or when a spreadsheet cell contains a specified value.

Great for time-bound assignments, event registrations with limited seats, or other first-come, first-served signup scenarios.

Easy setup!  Just launch, set the limit type, and save:

- Maximum number of responses - Form evaluates on each new submission and shuts off once a limit has been reached.

- Specific date and time - Timer will shut off form on that date, down to the minute.

- Spreadsheet cell value equals - specify a spreadsheet cell (e.g. "Sheet1!A2" in the form destination sheet that must equal a particular value, and the form will evaluate on each new form submission.
