One such example is XR+ who recently launched a new browser based AR platform, compatible with iOS and Android built-in browsers. They describe it as the YouTube of AR, with users able to upload, view and share their own content.  You can see a preview of the service in action on YouTube.

XR+ uses the fiducial markers for tracking, but the promise of the new AR platforms, and most of the promotional material we’ve seen recently is markerless.

Google has demonstrated a prototype called Article, that demonstrates their vision of markerless browser-based AR, although currently this requires an experimental browser for iOS, and Android.

Browser-based AR is in its infancy, but if you’re interested in finding out more about these two implementations you can try XR+ by visiting their website, read about Google’s experiments on their blog and find the Article platform source code on Github.
