Questions
Questions about Responsive.
Is the responsive tester free?
Partly. The free version shows 3 devices. Pro unlocks all 27 devices, device frames, image downloads and replay.
Which devices are included?
27 devices across smartphones, tablets and desktops, plus a custom size.
Can I test a page that needs a login?
It may not work: sites with a login may not see your cookies inside Responsive, so you could see the logged-out version.
Can I download screenshots of every device?
Yes, with Pro. Download an image per device or of all devices together, with dark or silver frames.
Does the export preview use the same devices?
Yes. When you export a component, the isolated preview shows it at 375, 768, 1024 and 1280 px and in device frames.
How do I test a website on different screen sizes?
Open Responsive in Pickode and choose devices among smartphones, tablets and desktops, or set a custom size. You can rotate, zoom, use a mobile user agent and scroll every view in sync. Free shows 3 devices; Pro all 27.
What does it mean that a website is responsive?
A responsive website adapts its layout, images and text to the screen width, from phones to desktops, usually with CSS media queries. Pickode's Responsive tool lets you check that on real device sizes.
Is there a responsive checker Chrome extension?
Yes. Responsive is part of the Pickode extension and works in Chrome, Edge, Brave, Opera, Arc, Comet and Firefox 140+, on the page you're already viewing.
