Hi all, 

I've just installed the Odoo CRM community version 15.0 througout the Marketplace of Jelastic and I was wondering if by a developer point of view is truly open source and free, or freemium? 

I know that may resemble a silly question, but as per many other open source web app (ex. moodle, etc...) can I, using of course the documentation start to customize the installed version out of the box to fulfill the requests of my company?

Kind regards, 

Chris
