Does anyone know of an alternative to LaunchRock, where the email addresses obtained are validated, there is an API, and a way to migrate the data out?
My friend recently tackled this in a hackathon using FireBase as the backend, and gh-pages as a static host. He hasn't open sourced it yet, though (I've just pinged him with this thread).<p>It will be available at github.com/shashankmehta/firelaunch as soon as he does.
