Looking at their API docs, why would you use this instead of PhoneGap?
For instance, with PhoneGap, I can easily add native Objective-C or Java classes to my project to do things you just can't do with a native UIWebView.
I solved some really interesting enterprise-y integration problems on PhoneGap by writing some Objective-C. Looks like forge makes you modify the authentication server to return a forge://url which is nice, but could be tough to get some IT environments to do. (http://docs.trigger.io/en/v1.2/features/modal.html#external-...)
I do see that you can build browser extensions, which is a nice feature.
PhoneGap's a good product, and definitely has its place. However, we've heard from lots of people (some of whom we now value as customers) that for apps which don't need bespoke native functionality it can be too heavy-weight: this affects everything from tooling to build process to bloat in the platform itself.
Some of the main tangible benefits we offer over our competition, and PhoneGap in particular:
* much faster build process (apps re-generated across 6 platforms in < 1s in the main-line case)
* unlimited support, and help prototyping your app at higher tiers: Nitobi is/was basically a consultancy based on PhoneGap whereas we see ourselves as building and licensing a software platform
* guarantee we'll never be bought by Adobe and get rolled up into Dreamweaver (not a guarantee)
* make no requirements on the IDE or other tools you use - you're good to go with a terminal and a text editor
In general, we try to be light-weight, get out of the way as much as possible, and offer a great, streamlined experience for users writing apps in the bottom 50% of the complexity spectrum.
