So far we have written small apps like Campfire, Hipchat, Github Issues, Pivotal tracker etc to showcase the capabilities of the platform. The app directory is at https://supportbee.com/apps
The development process should be (hopefully) pretty straight forward. We have also bundled a nice web console to help you develop/test your apps quickly. I would love for you guys to give us feedback on the development experience
I would love to answer any questions or hear your feedback. Our apps repo is at https://github.com/supportbee/SupportBee-Apps. You can star it if you want to follow the development. Thanks!
