Bungee Connect , which leaves private beta today, competes with all of these. But the company, based in Utah, thinks they have the advanced features to attract a much different audience than most of those startups. They’re targeting hard core developers, not non-developers who want a way to create simple software programs to solve problems at the office.
Bungee Connect is a single online environment for developers to write, test, deploy and host applications. Like Force.com, it is a platform-as-a-service. The service is free until end users actually start using the products built and deployed on the service.
Dana Gardner wrote an excellent overview of the service a year ago when Bungee Connect was first introduced.
