SponsorBlock is an open-source crowdsourced browser extension that automatically skips sponsor segments and other annoying parts (intros, outros, subscribe reminders) in YouTube videos. It pairs with a server and public API where users submit segment timestamps, using a privacy-preserving query system.
Use cases
- skip sponsor segments in youtube videos
- automatically skip youtube intros and outros
- block subscribe reminders in youtube
- crowdsourced ad skipping for youtube
- self-host a sponsorblock mirror or API
- use sponsorblock with invidious or mpv
When to choose
- you watch YouTube regularly and want sponsor segments skipped automatically
- you want a privacy-respecting, open-source alternative to ad-style blockers for in-video promotions
- you want to contribute segment data or use the open API in your own tools
When to avoid
- you need to block YouTube ads themselves - use uBlock Origin instead
- you need offline video processing rather than in-browser playback enhancement
- you watch on platforms without a SponsorBlock port
