A couple of key points, once you purchase the license you will have full access to the source-code, it also supports real-time editing of the same kanban board courtesy of socket.io.
I'm curious about how you're doing per user pricing. If the source is open, how are you enforcing limits on the number of users? Is a portion of the code base closed source? Or are you just using the honor system? I'm asking because I sell hostable software too and I've been thinking about per user pricing for a while, but I haven't made the switch yet.
I just released the beta version of the site so I don't have any data-points yet. But I'm hopefully going to bank on enterprises mostly purchasing the software, and those are going to be entities that I know will most likely respect the per-user contracts. The entire source-code will be available to the customer once they purchase the license. I've had to make a lot of hacks when tailoring 3rd party software with pieces of their code closed-source, so I hope to alleviate that pain for other developers.
What type of software do you sell, and how are you currently charging clients?
Would love to see some screenshots/demo video. Great to see you're opening up the source for customisation. Does this mean it will be open-source, or just open to internal customisation?
My ultra-pedantic feedback would be to change:
The Most Simple kanban board out there.
to
The simplest Kanban board out there.
Thanks for the feedback. It will be open for just internal customization for customers. This was a huge pain-point for me when dealing with 3rd party software vendors.
I will implement that word change later and possibly get some screenshots up! Users are free to check out the board in action here w/ no signup: https://www.taskfort.com/view/10
Trello's pretty awesome, but there's no hosted version. Jira has a hosted kanban version but that's a tank. A lot of enterprises in the financial industry can't use 3rd party web-apps because they're hosted on someone else's server.
