Without CJT

  • Editing functions.php for every PHP customization
  • Pasting scripts into different theme settings
  • Adding plugins for simple functionality
  • Searching through files to find old code
  • Applying snippets globally when they only belong on one page

  • Work with CSS, JavaScript, PHP and HTML
  • Assign code to the content where it's actually needed
  • Manage changes directly from WordPress
  • Build a cleaner, more maintainable customization workflow
Your custom code stays organized, accessible and easier to maintain.
Keep your customizations separate from your theme while managing everything from one familiar WordPress workspace.

One Toolbox. Endless possibilities

More Control Over Your WordPress Code.

Whether you’re making a quick CSS adjustment or managing advanced custom functionality, CJT gives your code a proper home.

Create Organized Code Blocks

Separate customizations into individual Code Blocks instead of building one giant collection of snippets. Give each task its own place so it’s easier to understand, edit and maintain.

Put Code Where You Need It

Apply code to specific pages, posts, custom post types and categories. CJT PLUS expands your targeting options with tags, site-wide placements, URLs, Regex and additional locations.

Work in the Languages You Already Use

Manage CSS, JavaScript, PHP and HTML from inside WordPress with syntax-aware editing.

Add Scripts Without Theme Editing

Add analytics, chat widgets, tracking scripts and other third-party code without repeatedly modifying your WordPress theme.

Build Functionality Without Another Plugin

For smaller custom features, use JavaScript or PHP Code Blocks instead of automatically reaching for another single-purpose plugin.

Protect Your Work With Revisions

Keep previous versions of your Code Blocks so changes don’t have to mean losing working code.
