What Is SponsorBlock?

SponsorBlock is a community-driven database that marks sponsored segments, intros, outros, and filler in YouTube videos so compatible apps can skip them automatically.

Where it is available

Browser extensions, ReVanced (via patch), SmartTube, LibreTube, Tubular, and FreeTube support SponsorBlock. YouTube Vanced included it before the project shut down.

How submissions work

Users submit segment timestamps that others vote on. Crowdsourced data improves over time but may miss new sponsor styles until contributors tag them.

Before you install

Always download patchers, GmsCore, and APK bases from official project pages or trusted mirrors listed in our safety guides. Mismatched versions are the most common cause of playback and login failures after setup.
