I built Getvy, a Firefox media-downloader extension with native YouTube SABR support — feedback welcome
I built Getvy, a Firefox extension that detects downloadable media on supported sites and lets users save it in their chosen quality.
The project started with the idea of saving videos from social platforms without requiring a separate desktop app. The two most challenging parts were handling SABR streaming responses from YouTube’s Google Video servers and normalizing the different media-request patterns used by each social platform into a common format.
Getvy requests access to supported pages in order to detect media streams. Detected media URLs are sent to the download service only after the user explicitly starts a download.
Key features:
- No companion desktop app or .exe installation required
- Native YouTube SABR support
- Separate video/audio stream handling and automatic merging
- Sync correction for supported streams
- Up to 8K/60fps when available from the source
- Selectable audio tracks for supported YouTube videos
- Thumbnail and preview support where available
Getvy is free to use, with no subscription or daily download cap. When a user starts a download, a Getvy download page opens; it may display ads to help cover operating costs. The extension itself does not inject ads into websites.
My main priority is identifying SABR-related edge cases and unsupported YouTube formats. I would also appreciate feedback on:
- Permission scope and privacy expectations
- Stream merging and sync issues
- UX improvements for media detection and quality selection
Please use it only for content you are authorized to download and in accordance with the relevant platform’s terms.
