Overview
What Feedback Form (Common Ninja) is
Feedback Form is Common Ninja's survey-style form widget, pre-tuned for ratings and comments and embedded on a Squarespace page with one line of code. The old copy here described buttons, tabs and accordions, a different product. It is their Form Builder engine with defaults for satisfaction surveys.
What it does
The vendor page lists star and scale ratings, multiple choice and checkboxes, dropdowns for categories, long-form text for open comments, and file or image upload for screenshots. Fields can be grouped under section headers and reordered by drag and drop. Notification emails go to whoever owns each feedback flow, honeypot fields and optional CAPTCHA keep junk out, and every response is saved to the Common Ninja dashboard and exportable to CSV.
Who it suits
Product feedback, customer satisfaction surveys, post-purchase and event feedback, staff feedback and feature requests on a Squarespace site, without paying for a separate survey tool.
One honest caveat
Squarespace's Form Block can collect a comment box for free, but has no rating scales or file uploads, which is the real reason to use this. In return your responses live in Common Ninja's dashboard on a third party script, and there is no reporting beyond the list and CSV export, so analysis happens in a spreadsheet.
Setup and pricing
Build the form in Common Ninja's editor and paste the embed code into a Squarespace code block (Core, formerly Business, plan or higher). Common Ninja is recurring software: the free plan covers one feedback form with no time limit, and paid tiers add forms, submission volume, premium skins and the advanced features noted above.
