There are many options that are not phonegap build. "Build" is Adobe's
solution for cross-platform build for as many platforms as you support.
You probably have a preferred development environment already..
and that env may support deployment, depending on platform(s).
My company has a cloud solution,
AppLaud Cloud, for Android, which
makes development, debug and deploy pretty easy, if your app is
pure HTML/CSS/JS. With the companion app,
AppLaud App, you can
run the app on the device immediately after saving code file.
