All The Bug Genie development happens via github.com, and we share all code back to the open source edition (OSE).
The open source license used for the OSE is MPL 1.1, which is one of the more flexible open source licenses available when it comes to modifications, redistributions, etc.
Even though all main features will become available in the OSE eventually, there may be a delay before features introduced in the purchasable version appear in the OSE.
Some premium features are only available to paying customers, available via the account page. These features are not included in the main package, and are not open sourced or redistributable. For more details, look at the comparison chart on our "Get The Bug Genie" page.
