Tired of editing theme files to add custom scripts or styles?
WP Coder lets you insert custom HTML, CSS, JavaScript, and PHP snippets directly from your dashboard — no coding in theme files required. Gain full control and flexibility over your site.

Why WP Coder?

Header & Footer Scripts: Add Google Analytics, Tag Manager, verification meta tags or any script to every page — in <head>, right after <body>, before or after the post content, or before </body>.
Shortcodes & a Gutenberg Block: Place a snippet anywhere with [wp_code id="X"] or the WP Coder block, with a live preview in the editor.
Reusable Snippets with Attributes: Define fields once — text, textarea, number, range, URL, image, color, date — and fill them per shortcode or block. Use them in your code as {{name}}.
Images Done Right: An image attribute gives you its URL, alt text, size, srcset and a ready <img> tag with WordPress lazy loading and fetch priority applied.
82 Ready-made Snippets: Turn on common tweaks for security, performance, the editor, media, comments and login with one switch — and find any of them with instant search.
Safe by Design: Only administrators can add code. A PHP error in a snippet is caught and logged instead of breaking the page, and Safe Mode (?wpcoder-safe-mode=1, for administrators) gets you back into the admin if Global PHP or an included PHP snippet ever locks you out.

Ideal For

Developers: Test snippets, hooks and PHP quickly, with a code editor that feels like home.
Marketers: Insert tracking pixels, analytics and ad scripts site-wide in a minute.
Designers & Bloggers: Build reusable blocks, customize layouts and styles.

Key Features

Tabbed editor for HTML, CSS, JS and PHP with syntax highlighting, linting, code folding, find & replace, full screen and Ctrl/Cmd+S to save.
Live Preview: See your HTML and CSS rendered as you type, right next to the editor.
Smart PHP handling: run in admin, front end, everywhere, or only where the snippet is placed.
Include external libraries (Google Fonts, CDN scripts & styles) with async / defer.
Minify HTML, CSS and JS, or obfuscate JavaScript.
Test Mode: Preview snippets as an administrator before visitors see them.
Organize: Several tags per snippet, pin the ones you use most, filter and bulk-edit the list.
Import/Export snippets between sites.
Customizable Interface: Hide unused editor tabs and add NAV comments to jump around long code.
Lightweight — pages that do not use a snippet get no extra CSS or JavaScript.
