I would to buy a single licence with no support (170$ is affordable for me but not (yet) 470$).
Does the version would be the PRO version or the “GPL” version but usable for private projects ?
I mean, pivot table, customized scrollbar etc etc will be in this version with no support ?
I think 470$ is not too high regarding the amazing job you do (really) but i can’t get the support today…
When you buy Webix Developer license you get Webix Pro with all pro features. pivot, custom scrollbars and etc. without support. You can buy support plan separately if you need it.
Great ! I’m a (small) new Webix customer from now !

Is that kind of licence still available?
