Do you need to buy a run time license from Sencha if your application code written is developed in Ext JS and deployed on a web server?

Just save yourself the hassle and choose a different framework. – pllee Aug 11 '12 at 1:36
@pllee, care to tell us why it is a hassle? – NoChance Aug 11 '12 at 2:23
@EmmadKareem I would but I don't think this is the best place. You can see my contact info in my profile. – pllee Aug 11 '12 at 15:26

If your server app is open source, no... I.e. you give the code away freely

If you don't want to give the code away, you need a license per developer working on the site.

So if it was commercialized software application using Sencha Ext JS, and we had 5 developers who are currently developing the application and 10,000 users connecting to the production web server hosting the application, we would only need to buy licenses for 5 developers? – MacGyver Aug 10 '12 at 23:42
Yes, 5 licenses – Jonno Aug 11 '12 at 0:07
