Since Instagram released its API earlier this year, support apps for the imaging social networker started popping up bit by bit. One of the main troubles with Instagram was that you can't have a proper newsfeed of pictures on a web. You could only see a feed on the iPhone app. This is where Extragram comes in. Extragram was created by a five person team, and is designed to give you Instagram access on the web.
The Extragram feed in Grid view. Rolling over a picture lets you interact with it.
Users can choose between three different layouts to view pictures, grid, filmstrip, or map. Each view works on the layout of the original Instgram feed and places images a little differently. When users roll over the photos, they can interact with them, either by liking them or commenting on them as well as seeing other peoples' likes and comments. The web app also allows users to search for people, photos, hashtags and places.
Gramfeed was another such Instagram web app released a few weeks ago, similarly formatted. We're going to see more apps for Instagram coming as developers can see the tangible benefits of working with the Instagram API.
