This is a commercial plugin licensed under the Craft License. It will be available on the Craft Plugin Store soon. See LICENSE.md for details.

This plugin is in active development and not yet available on the Craft Plugin Store. Features and APIs may change before the initial public release.

Code field with a real editor — live syntax highlighting in the Control Panel, with line numbers, tab/indent handling, undo/redo, and an optional in-editor language switcher
~177 languages — Prism's full language set, bundled and loaded on demand (with dependency resolution); choose which appear in field dropdowns
25 themes — from classic Prism themes to Dracula, Nord, One Dark, VS Code Dark+ and more; set one plugin-wide or override it per page
Highlighting extras — line numbers, copy-to-clipboard button, matching-brace highlighting, and inline CSS colour swatches
Twig API — print a Code field, re-render with overrides, or highlight any string with the |highlight / |prism filters
Integration trait — let other plugins highlight code with graceful fallback when this plugin isn't installed
Bundled & offline — Prism core, all languages, and all themes are served from the plugin's own assets (no CDN)
CSS-variable theming — restyle the wrapper and copy button without overriding selectors
12 languages — Control-Panel UI translated out of the box
