Everything a power user
actually needs

Built for people who watch a lot of video and want more control than the default player gives them.

Playback Speed Control

Speed from 0.1× to 16× with quick-tap chips. Keyboard shortcuts adjust on the fly without touching the popup. Speed persists across tabs and sessions.

Common questions

Does VideoFlex collect any data?
No. All settings are stored locally in your browser using Chrome's built-in storage. Nothing is ever sent to a server. No analytics, no tracking, no ads.
Do I pay again after an update?
Never. One payment covers every update forever. We don't do subscriptions.
Does it work on YouTube?
Yes — speed control, visual filters, EQ, loop, PiP, and emergency mode all work on YouTube. Video downloads are blocked by YouTube's own DRM, not by us.
What is Emergency Mode?
Press the backtick (`) key and your current tab closes instantly. A safe website you configured opens in its place. Press the key again and your video reopens at the exact second you left.
What browsers are supported?
Chrome and all Chromium-based browsers (Brave, Edge, Arc, Opera). Firefox support is planned.
Can I get a refund?
Yes. If VideoFlex doesn't work for you, email us within 14 days for a full refund — no questions asked.
