HTML5 Universal Speed Hack

Speed up or slow down HTML5 games, videos and audio (SoundCloud, YouTube, reels) plus timers, animations and Web Audio clock.

HTML5 Universal Speed Hack Take full control of time inside your browser. Speed up or slow down HTML5 games, Unity WebGL games, videos, audio and interactive websites by controlling the JavaScript time functions that power them. ⚙️ What does it do? The extension hooks the time-related JavaScript functions used by web pages and games (timers, clocks, animation frames and media playback) and lets you run them faster or slower. Perfect for gamers, developers, QA testers and automation users. 🆓 FREE VERSION (included) ✅ Speed control from 0.1x to 3x — always available ✅ Free daily boost: up to 5x for 1 hour of active use per day (resets automatically each day) ✅ Per-tab enable/disable ✅ On-screen speed indicator (OSD) ✅ Keyboard shortcuts (Ctrl+Shift+Arrow, Ctrl+Shift+X, Alt+Shift+R) ✅ Apply settings to all tabs ✅ Blocked-sites list ✅ Optional floating control box ✅ Reload-on-expiry option ✅ 10 languages (English, Português, Español, Français, Italiano, Polski, Русский, 日本語, 한국어, Deutsch) 🔒 Privacy: no account, no tracking, no analytics, no data collection.
