Twitch's native live player does not allow viewers to rewind or fast-forward live streams. This extension solves that by injecting custom controls that let users go back up to 30 seconds (the Twitch buffer limit) and forward.

The extension's content script runs on https://*.twitch.tv/* pages. It detects the live video player, injects custom UI controls (rewind, forward, go-live, settings, donate buttons) into the player's control bar, and uses the HTML5 video API to seek within the buffered portion of the stream (up to 30 seconds). Keyboard shortcuts (Left/Right arrows) are also supported.

Target users: Twitch live stream viewers who want to catch up on missed moments / Twitch streamers and their audiences

The extension only works on live streams, not VODs or clips (as documented in the extension itself).
Analysis is based on static source code; runtime behavior on actual Twitch pages was not tested.
The extension relies on Twitch's internal DOM structure (e.g., .player-controls__left-control-group), which could break if Twitch updates their UI.

Monetization

No paid features detected

The extension is completely free. There is a 'Buy Me a Coffee' donation button in popup.html and content.js, but this is for voluntary support, not a paid feature gate. No subscription, premium tier, license key, or payment API is implemented. All rewind functionality is available without any payment.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login mechanism, nor does it require a Twitch account to function. The content script injects controls into the Twitch player regardless of user authentication. While Twitch itself may require login for some features, the core rewind functionality works on live streams without requiring the user to log in via the extension or destination service for the basic workflow.
