SponsorBlock is an actively maintained, widely contributed-to browser extension, but its development is heavily concentrated in one contributor and its shared segment data depends on the project’s API.
Good fit if
- You watch YouTube or Invidious and want community-submitted segments skipped automatically.
- You are comfortable using the available browser extension or a documented third-party port.
- You can comply with the GPL-3.0 license when modifying or redistributing the extension.
Look elsewhere if
- You need sponsor detection that works without community-submitted segment data.
- Your integration cannot depend on SponsorBlock’s API or database terms.
- Your project cannot accept GPL-3.0 licensing obligations.

Overview
SponsorBlock uses viewer-submitted timestamps to skip sponsor segments in YouTube videos. Users can submit segments through the extension, which then skips matching segments for other viewers.
It also supports categories such as intros, outros, and subscription reminders, and works with Invidious. Browser extensions are available for Chrome/Chromium and Firefox, with links to other platform options in the project documentation.
Key Features
- Automatically skip crowdsourced sponsor segments in YouTube videos.
- Submit segment timestamps for other users to benefit from.
- Handle additional categories, including intros, outros, and subscription reminders.
- Support Invidious as well as YouTube.
- Provide browser extensions for Chrome/Chromium and Firefox, with documented options for other platforms.
- Publish API documentation and a downloadable database for integrations and ports.
Use Cases
- YouTube viewers who want to skip submitted sponsor segments without manually seeking through videos.
- Viewers who also want to bypass marked intros, outros, or subscription reminders.
- Invidious users looking for crowdsourced segment skipping.
- Developers of compatible clients or ports who need to use the project’s API or database, subject to its terms.

Getting Started
Install the extension from the Chrome Web Store or Firefox Add-ons. See the repository README for other platforms and build instructions.
Considerations
The project is active, with recent commits and releases, and contributors have closed issues promptly in the measured period. However, most contributions come from one person, so project continuity depends substantially on that maintainer. The extension relies on crowdsourced submissions and the separately maintained SponsorBlock server; the README also points integrators to API and database terms. The extension is GPL-3.0-or-later, which matters when redistributing modified code.
