FormGuard is a focused Google Forms add-on for teams that need operational controls inside the form editor. It brings response limits, schedule-based opening and closing, notifications, and answer choice controls into one place so the form stays manageable after launch.
FormGuard is designed around the most common form-control tasks that otherwise end up spread across manual checks and small scripts.
Close a form automatically after a configured number of submissions and show a clear custom message to respondents.
Set future open and close times so a form becomes available only during the intended collection window.
Remove or disable answer options once they reach capacity, which is useful for slots, sessions, or inventory-like choices.
Notify the owner when the form closes or when new submissions arrive, depending on the rules you enable.
A straightforward setup path for reviewers and first-time users.
Start with the exact control problem you are trying to solve.
Compare native Google Forms controls, Apps Script, and FormGuard for response caps and scheduled windows.
Set a cap, show a closed-form message, and notify the owner when capacity is reached.
Answer the common FAQ directly and explain what a 100-response cap can and cannot guarantee.
Explain the practical workshop-capacity pattern without pretending Google Forms is strict reservation software.
Handle volunteer role capacity with a realistic overflow path instead of promising a full staffing backend.
Manage workshop seats, appointment slots, roles, and other limited options in one form.
Close the main form cleanly and hand late users to a separate waitlist or backup path.
See when per-option quotas are enough and when your workflow really needs quantity-aware inventory logic.
Explain why already-open forms can overshoot capacity and how to run safer signups.
