UltraWideo kills black bars. It finds any video on any site — including cross-origin embeds — and rescales it to fill the screen, whether that's an ultrawide, a dual-monitor setup or an ordinary 16:9 laptop. Free is one global config; Pro adds per-site and per-video profiles, letterbox detection, WebGL ambient light, real-time sharpening and cloud sync. One codebase ships Chrome and Firefox, a Nuxt site on Cloudflare sells it, and a self-hosted licensing API keeps it working offline.
