Visual Composer was designed and built to be easily extendable. Currently we have 100+ Visual Composer addons that were designed to take your site to the next level. Right after addon activation it will add extra functionality to your site.
Are you a developer? If so, then you should definitely check our knowledge base and make your plugin “Visual Composer ready” or create brand new visual composer addon with new content elements and sell it on CodeCanyon (extra cash never hurts, right?).
