Ally adds a self-hosted accessibility widget to your ProcessWire site. Powered by Sienna (MIT), the JS bundle ships with the module and is served from your own server — no external CDN, no third-party requests at runtime. The OpenDyslexic font used by the dyslexia-friendly mode is also bundled locally (vendor/fonts/), so even that feature makes no off-site requests.

- ProcessWire 3.0.200+
- PHP 8.1+
- The widget is injected by hooking
Page::render. If you serve pages through ProCache (static HTML files bypassing PHP), the hook does not run and the widget is not injected on cached pages — exclude those pages from ProCache or disable caching for them if you need the widget there. - Overlay accessibility widgets supplement, but do not replace, building accessible markup. Use Ally alongside good semantic HTML, not instead of it.
