Can you use extJS for an business application for free?

Well, you can if any of the following statements are true.

  • You open-source your app under GPL v3.
  • The app is only for internal use in your company.
  • The app is used by your company to provide a service and not directly distributed to the customer e.g. most web pages (according to GPL this is interpreted as an internal use of the app - if Ext team would have chosen to prohibit that, then they would have used Affero GPL, which directly forbids that).
