The speed extension built for people who want to set it once and forget it.
Set speed once per site, never touch it again. Open YouTube — auto 2x. Open Udemy — auto 1.5x. Open a course lecture — your last speed is already applied. A lightweight popup and Alt+↑/↓ shortcuts handle adjustments — no floating OSD overlay to fight with.
- Per-site auto-speed — each site remembers its own speed setting
- "This site" or "All sites" modes for flexible control
- 0.5x – 16x with 0.25x steps on any HTML5 video
- Pitch-preserving audio — voices stay natural at any speed
- Privacy-first — zero tracking, zero telemetry
- 📚 Online course learners (Udemy, Coursera, Bilibili courses)
- 📺 Binge-watchers who always watch at 2x
- 🙅 Anyone tired of complex shortcuts and floating on-screen controllers
- Power users who want 20+ customizable keyboard shortcuts
- Users who need per-tab (not per-site) speed memory
- Users who prefer a floating OSD controller
Speeding stays intentionally minimal. If you want a full-featured controller, VSC is the better choice.
Most video speed controllers forget your settings when you switch tabs. Speeding remembers your speed per site and keeps audio pitch natural by default — no configuration, no signup, no tracking.
