At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.

If you want to temporarily disable the form or make it inactive, you can follow the screenshot below.
Navigate to "Setup & Embed"->Preferences->General Settings->Status->Change it to "Disabled".
This will make your form disable, inactive or unavailable when the Form URL is visited.
