Can a web gateway open YouTube?
Some public video pages may load basic preview information, but modern video platforms depend on JavaScript, cookies, player APIs, and regional licensing systems. A safer read-only gateway may intentionally remove parts that a full video player requires.
Safe and lawful use
Use public video access only where it is allowed by your organization, local law, and the platform terms. Unblock Web is designed for approved public resources, not for bypassing access controls.
Better alternatives
If a classroom, library, or team needs a video resource, ask an administrator to approve the official domain or provide an allowed learning link.
