Not a week has passed since the official release of Apollo, a platform allowing web applications to run outside a browser, and they’re already in trouble (i.e. there’s competition), reports TechCrunch. Here are three services that offer pretty much the same experience that Apollo does:

1. The third iteration of the popular open-source browser, Firefox, will allow similar functionality through enabling offline access to local datastores
2. Dekoh allows you to bring together the web and your desktop by allowing developers to create applications on their platform.
3. Lastly, Slingshot, let’s developers to create applications that similarly work online as well as offline.

For a look at the differences between the various applications, technical overviews, and more commentary, head on over to TechCrunch.
