Ultra-light, privacy-first web accelerator for very slow internet. Blocks trackers, IP beacons, heavy embeds, optimizes images, reduces fingerprinting, and adapts automatically.
HyperLite Web Accelerator Extreme Edition
What Is HyperLite
HyperLite Web Accelerator is a privacy focused, low bandwidth optimization userscript designed for people with:
Very slow internet connections
Unstable or rural networks
Mobile hotspots or data limits
VPN or Tor usage
Older or low powered devices
It improves page load speed, responsiveness, and privacy by removing unnecessary network requests and heavy content while remaining safe for modern websites.
This script is a complete remake by Domopremo, inspired by the original Super Fast Load userscript.
The original author is fully credited.
Goals of This Script
HyperLite is designed around realistic performance gains rather than gimmicks.
Primary goals include:
Reducing bandwidth usage
Reducing DNS lookups and IP leaks
Speeding up visible content loading
Improving usability on poor connections
Avoiding breakage on modern sites such as React apps and YouTube
Key Features Explained
Adaptive Performance Modes
HyperLite automatically selects a mode based on your network conditions.
Mode When It Activates Behavior
Balanced Normal broadband Light tracker blocking and safe defaults
Slow Internet Save Data enabled or very slow connections Font blocking, image optimization, autoplay disabled
Extreme Very slow or Tor like connections Aggressive tracker blocking and fingerprint reduction
No manual setup is required.
Tracker and IP Beacon Blocking
HyperLite blocks many known tracking systems including:
Analytics services
Tracking pixels
Session replay tools
IP logging endpoints
Background sendBeacon requests
This reduces IP correlation, silent background traffic, and post load tracking without breaking logins or captchas.
Image Bandwidth Reduction
On slow connections, images are optimized by:
Forcing lazy loading
Enabling asynchronous decoding
Removing responsive srcset attributes
This can save hundreds of kilobytes or even several megabytes per page.
External Font Blocking
External fonts such as Google Fonts and WOFF files are blocked automatically in slow modes.
Benefits:
Faster text rendering
Fewer DNS and TLS connections
Lower bandwidth usage
System fonts are used as a fallback.
Autoplay and Media Control
When slow modes are active:
Video and audio autoplay is disabled
Media preload is reduced to metadata only
This prevents unnecessary buffering, CPU spikes, and data usage.
Lazy Loaded Embeds
Heavy embedded content such as social media widgets and ads are replaced with a simple Load content button.
This ensures:
Zero bandwidth usage unless requested
Faster page rendering
User controlled loading
Fingerprint Surface Reduction
In Extreme mode only, HyperLite reduces exposed fingerprint data by:
Normalizing CPU core count
Limiting reported device memory
Hiding plugin and MIME lists
This does not make you anonymous, but it helps reduce fingerprint uniqueness when combined with VPN or Tor usage.
Bandwidth Savings Estimator
HyperLite estimates how much data was saved and logs it in the browser console, for example:
[HyperLite] Mode: SLOW | ~640 KB saved
This provides visible feedback on the script’s effectiveness.
Per Site Disable Button
If a website does not behave correctly:
Click the ⚡ HyperLite button in the bottom right corner
The page reloads automatically
HyperLite is disabled only for that site
There is no need to uninstall the script.
YouTube Behavior
On YouTube, HyperLite:
Stops autoplay
Avoids unsafe buffering modifications
Keeps playback logic intact
Adds a lightweight helper button if enabled
Video playback remains stable.
Privacy Philosophy
HyperLite:
Does not collect any user data
Does not inject advertisements
Does not communicate with external servers
Uses only localStorage for per site preferences
Runs entirely inside the browser
All processing happens locally.
Limitations
Important limitations to understand:
This script cannot increase your actual internet speed
It cannot compress encrypted traffic
It cannot bypass ISP throttling or CDNs
Visual appearance may change due to font blocking
Extreme mode may affect rare hardware detection sites
These tradeoffs are intentional to prioritize speed and privacy.
Recommended Use Cases
HyperLite works best for:
Slow or unstable internet connections
VPN or Tor browsing
Low end devices
Metered or data capped connections
Privacy conscious users
Troubleshooting
If a site looks broken or incomplete:
Use the per site disable button
If fonts look different:
This is expected behavior in slow modes
If videos do not autoplay:
This is intended behavior
