WP Events Manager
Events Manager is a free and feature-filled events plugin for the WordPress platform, providing the ability to publish events, locations and manage bookings among many other features.
Events Manager Pro is an add-on to Events Manager, which extends the functionality of the free plugin to provide a further layer of tools and features for professional event organizers. Pro uses the very same actions and filters in Events Manager, which any developer can use to extend the plugin as they see fit (a testament to EM’s flexibility).
Events Manager remains an integral part of the Pro plugin and therefore we will always remain committed to maintaining, supporting and adding more features to the free plugin because Pro depends on it. Given we started this plugin as a labor of love, we don’t ever intend on changing this approach!
