ExtenderX is an all-in-one WordPress site enhancement plugin. It adds an accessibility toolbar, scroll and entrance animations for Gutenberg blocks, dark mode, a sticky header, maintenance and coming soon modes, an announcement bar, header/footer code snippets and 50+ other site tools — all managed from one dashboard, on any theme.
Turn on only what you need. A disabled feature adds zero CSS and zero JavaScript to your pages.

What you can do with the free version
- Make your site easier to use — a visitor-facing accessibility toolbar with 11 display tools, 4 one-click profiles, a skip to content link and visible keyboard focus outlines.
- Animate any Gutenberg block — entrance, floating and 3D tilt animations on core blocks and third-party blocks, with no new blocks to learn.
- Add dark mode — a light/dark toggle for visitors that works with any theme.
- Improve navigation — sticky header, sticky footer bar, back to top button, scroll progress bar, scrollspy and smart auto-hiding header.
- Launch and maintain — maintenance mode and coming soon mode, with admins keeping full access.
- Promote offers — announcement bar, floating call-to-action button and CTA pulse animation.
- Add tracking and custom code — insert header and footer scripts and manage HTML, CSS and JavaScript snippets without editing theme files.
- Protect content — disable right click, text copy, inspect and image drag.
- Publish faster — Save & Go adds “save and jump to…” actions to the post editor.
One plugin instead of many
ExtenderX covers jobs that usually need a separate plugin each:
- Accessibility widget / toolbar
- Block animation and scroll animation plugin
- Dark mode plugin
- Sticky header and back to top plugin
- Maintenance mode / coming soon plugin
- Announcement bar / notification bar plugin
- Insert headers and footers / code snippets plugin
- Content protection (disable right click) plugin
- Seasonal effects (falling snow) plugin
Fewer plugins means fewer updates, fewer conflicts and one consistent settings screen.
Why site owners choose ExtenderX
- Lightweight by design — conditional asset loading. Scripts and styles load only where a feature is enabled and actually used.
- Works with what you have — any classic or block theme, all core blocks, and block libraries such as Kadence Blocks, Spectra, Stackable and GenerateBlocks.
- Private — the accessibility toolbar sets no cookies, calls no external service and sends no visitor data to your server.
- Respects visitors — motion features honor the “prefers-reduced-motion” system setting.
- Honest free tier — the free features listed here are complete and usable on their own, not trials.
- RTL ready — full right-to-left stylesheet support.
Accessibility
Tools that let visitors adjust how your site is displayed, so they can read and navigate it more comfortably. Everything is off until you enable it, nothing is fetched from an external service, and no visitor data leaves their browser. These tools are one part of an accessible site — your content, your markup and your own testing matter at least as much.
- Accessibility Toolbar — a floating button that opens a panel of display controls, grouped into Text, Color, Content, and Motion & reading. Free tools: text size, a readable font, left-aligned text, high contrast, inverted colors, grayscale, a light background, underlined links, highlighted headings, hidden images, and paused motion.
- Quick profiles — Low vision, Dyslexia, Focus and Seizure safe each switch on a matching set of tools in one click, using only the tools you have enabled. Press again to clear.
- Keyboard shortcut — visitors open and close the panel with Alt+A from anywhere on the page. A badge on the button shows how many settings are active, and Reset all clears them.
- Remembered preferences — a visitor’s choices follow them from page to page, stored in their own browser. No cookies, nothing identifying recorded, and nothing sent to your server.
- Skip to Content Link — lets keyboard visitors jump past the header straight to your main content. Hidden until focused, and it moves focus properly rather than only scrolling. If your target selector doesn’t match, common landmarks are tried automatically.
- Enhanced Focus Outlines — a configurable ring (color, thickness, offset) around whichever element the keyboard is on, for themes that hide or wash out the browser default. Appears for keyboard input, not mouse clicks.
You choose which side the button sits on, how far up from the bottom, which tools appear, and whether the profiles row and the shortcut are offered. The toolbar is itself keyboard operable, announces changes to screen readers, and honors the visitor’s “prefers-reduced-motion” system setting.
Pro adds: seven more visitor tools (reading guide, reading mask, text spacing, content zoom, a dyslexia-friendly typeface, a large cursor, saturation control) · toolbar branding (colors, icon, size, stacking order, hide on mobile) · an Accessibility Statement generator that creates an editable draft page · an Alt Text Audit that lists media library images with no alternative text.
Block Editor Extensions (all free)
Six extensions added to the Gutenberg sidebar for every registered block — core WordPress blocks and third-party block libraries alike. No replacement blocks. No shortcodes.
- Entrance Animation — scroll-triggered effects (fade in, slide up, zoom, flip, bounce, and more) with duration, delay, and easing controls. Fires once when the block enters the viewport.
