Browser and OS compatibility

Collection is built in standard JavaScript and aims to run everywhere your customers do. It's tested and verified against current desktop and mobile platforms, and it's designed to degrade gracefully rather than break a page when it meets something older.

The guiding rule: if a browser still receives security updates from its vendor, collection is meant to work on it. The current and previous major versions of the evergreen browsers (Chrome, Edge, Firefox, Safari) are actively tested; the tables below list the verified baseline alongside the modern platforms collection runs on today. They're representative rather than exhaustive — any device with a current evergreen browser is supported even if it isn't named.

Operating systems

Desktop browsers

Evergreen browsers update themselves, so the minimum version is a floor, not a ceiling — keep the browser current and you're covered.

Mobile browsers and devices

On mobile, current versions of Safari on iOS/iPadOS, Chrome on Android, Samsung Internet and Firefox for mobile are supported. The table below lists verified devices with their portrait viewport size (CSS pixels, width × height); newer devices with the same engines are supported too.

How the snippet stays compatible

The standard snippet loads a build that suits the page automatically — it serves a jQuery-free bundle when no jQuery is present, and a jQuery-aware bundle when one is. The script is loaded asynchronously and attaches on load, so it never blocks your page from rendering, and it falls back quietly on environments it can't fully support.

If the widget doesn't show

If a survey doesn't render on a particular browser or device, it's usually a configuration or page-environment issue rather than a compatibility gap. Work through Troubleshooting first — it covers content-security policies, cookie-consent gating, duplicate snippets and the other common causes.

If you've ruled those out and believe it's a genuine compatibility problem on a current browser or OS, contact support with the browser, version and operating system so the team can reproduce it and either fix it or update this guidance.
