Nice. I'm currently seeking out a lean kanban-like board to self-host. It could be just me, but this seems to be closed-source and as such ranks a good way below libre alternatives like kanboard [1]. Interop with other systems is also a big deal for me, and the option to extend it myself if need be seems impossible with a closed system.

Are there plans to release the source code, or is there a documented API somewhere?
