Omusubi is a powerful WordPress form plugin with a visual builder right in the admin screen.

With just clicks and drag-and-drop, you can build the variety of forms a business actually needs: contact forms, lead capture forms, surveys, prize entries, recruitment applications and more. Submissions are managed from a tabular view in the admin and can be exported as CSV. Slack notifications, Google Sheets integration, reCAPTCHA, time-limited acceptance windows — everything you need for day-to-day operation is bundled in a single plugin.
