Very nice! Yours is much more than just a front-end editor, yours create complete apps.
EDIT: And yours is not MIT licensed and has separate commercial licenses.

It's AGPL. The commercial licenses are for people or companies who may want to modify it without releasing their modifications back to the community. If they don't want to contribute their code, they will at least contribute financially.
Do the commercial license cost 299$ per year? Is it limited per install, or company-wide?
It will be per install. I just put that price as a baseline. It will be adjusted depending on the needs and use cases. If you would like to talk about it in depth, shot me an email.
