Showcase: Shop Instagram Feed , 276 reseñas

The pro version is the better option

If you're looking for an app with a FREE plan to replace Shopify's built-in Instagram feed (that Shopify refuses to fix), this is a great option!

You can use the free version to replicate the old feed's functionality pretty closely. Unlike some of the other free options, this one actually includes REAL responsive functionality for the feed, so your images are still visible at a reasonable size on mobile devices, even if you have 6 columns configured for desktop. Some of the other free options I vetted simply scaled those 6 columns down on mobile, resulting in tiny thumbnails. In order to get actual responsiveness with those options, you needed to upgrade. On the contrary, this app's free version includes automatic changes to the row/column layout on smaller screens and is truly a responsive option.

On another note: I had to take off 1 star because the interface where I can configure my feed kept logging me out while I was trying to set it up. So I lost an in-progress configuration 2 or 3 times and had to click the App link from my Shopify admin page to get back to it. Once it's all set up, it seems to work fine though.
