Description
The Freelancer DevKit brings together in a single plugin the isolated testing sandbox, the custom CSS and JavaScript editor and the child theme generator that a developer uses on every new project, without needing to install a different plugin for each task. It’s for those who build custom WordPress sites and need to test code, style and function changes without risking the client’s site already in production.
Main Features of the Freelancer DevKit
- Child theme generator
Creates the child theme in a few clicks, ready to receive the client’s customizations. - Integrated CSS editor
Adds a panel to write and save custom CSS without a separate plugin. - Testing sandbox
Isolates code changes in a test environment before applying them to the live site. - Central customization panel
Brings together the site’s customization options in a single place in the admin. - Tools for freelancers
Bundles into a single package the tools a freelancer repeats on every project.
Benefits of the Freelancer DevKit

Who Is the Freelancer DevKit For?
- Those who build custom WordPress sites for several clients at the same time.
- Those who need to test new code before applying it to the production site.
- Those who set up a child theme for every project and want to skip the manual step.
- Those who organize custom CSS and JavaScript without depending on another plugin.
How to Download the Freelancer DevKit
The Freelancer DevKit is available for download here on Ultrapack. After downloading the file, install it under Plugins > Add New > Upload Plugin, activate it and start setting up the sandbox, the child theme and the code editor for your next project.
Every developer ends up building their own toolbox over the years, made up of loose plugins and code snippets scattered across notepads. Bringing all of that together in a single panel saves the work of rebuilding the same foundation for every new client and makes the process easier to repeat at scale.
