Be part of our future releases
By installing the Developer Edition plugin, <a href="https://elementor.com/?utm_source=wp-repo&utm_medium=link&utm_campaign=dev-edition-readme" rel="nofollow ugc">Elementor</a> users can now get a sneak peek of future features before they roll out. We invite you to participate and test features on our Developer Edition. This way, you’ll help us extend our ability to perfect our product and produce experimental and groundbreaking features.
The Elementor Developer Edition gives you first access to Elementor’s newest features and improvements. Each Developer Edition release will contain experimental functionalities that developers will be able to use to get familiar with the next releases before they are published. We will use this plugin to validate new features and gain feedback before they are released. 
This is why we don’t recommend using it on live sites. 
We recommend using it on staging environments only, and backing up your entire website before updating.

As a developer of Elementor addons, it's so much helpful for testing, debugging.

Very Helpful Plugin


As a Plugin Creator and Agency Owner, I find the Dev Edition to be an indispensable tool. It offers a sneak peek into upcoming features, enabling me to test and ensure my software remains optimally compatible. It's a boon for my agency as well, keeping us ahead of updates and always prepared for new releases.



I highly recommend anyone using Elementor or creating supporting products to utilize this edition in a test environment to fully harness its advantages. Disclaimer: I am also a long-term Elementor enthusiast and ambassador.
