xsbl — Accessibility for Every Site

About

xsbl makes any website more accessible — right from your browser. No code changes needed, no waiting for site owners to fix their pages. Just toggle the features you need and browse comfortably.

Whether you have low vision, color blindness, dyslexia, motor impairments, or sensory sensitivity — or you're a developer auditing accessibility — xsbl gives you real, working tools that apply instantly to any page you visit.
