Ads
14 features. One extension.
Each one attacks a different source of browser bloat. Together, they compound.
Ad & Video Ad Blocking
Including YouTube pre-rolls and Twitch ad breaks
Blocklists stop page ads and trackers before they run. Plus a dedicated video ad blocker that hides YouTube pre-rolls and mid-rolls and keeps Twitch streams running through ad breaks. Free, on by default.
Script Control
Stop scripts you never asked for
Manage third-party scripts per site. Reduce CPU and memory from trackers, analytics, and heavy frameworks running in the background.
Speed
Preload on Hover
Predicts your next click and starts loading in the background. Pages feel instant.
Prioritize Visible Content
Loads on-screen content first, delays off-screen resources.
DNS Prefetching
Resolves domain names in advance so connections start faster.
Clean
YouTube & Twitch Video Ads
Pre-rolls, mid-rolls, Shorts sponsors, and Twitch ad breaks all suppressed at the player layer.
Persistent Blocking
Auto-rejects cookie consent popups, hides sticky banners and ads that survive blocklists.
Stop Autoplay
Prevents videos from playing on their own. Silence by default.
Optimize Fonts
Replaces slow custom fonts with fast system fonts. Pages render faster.
Smart suspension
Adaptive Suspension
Ranks tabs by memory use times idle time and suspends the heaviest idle ones first — not naive oldest-first.
Unsaved Form Protection
Never suspends a tab with unsaved text sitting in a form. Your draft stays put.
Scroll-Position Restore
Return to a suspended tab and it reopens exactly where you left off, scroll and all.
Conflict Detection
Spots a rival suspender or blocker and warns you before two extensions fight over the same tab.
Control
Background Throttling
Reduces how often background scripts can run, freeing CPU for the tab you're actually using.
Block All Images
Maximum speed for research and documentation sites. Strips all images.
Safe Mode
Detects when features break a page and automatically recovers. Zero config.

20 open tabs cost Chrome 2–4 GB of RAM. Each suspended tab reclaims 90–95% of that memory. Add ad blocking and script control — you're looking at 30–60% less total usage.

Join the waitlistFrequently asked questions
Is SuperchargePerformance free?
Yes. Core features are completely free with no account required and zero telemetry. PRO unlocks advanced settings — manual suspension timing, full script blocking, background throttling, and more — for a one-time payment.
How much memory does it save?
Each suspended tab frees 90–95% of its RAM. Combined with ad blocking and script control, users typically see 30–60% less total memory usage. Open your task manager before and after to see the difference.
Does it work with other extensions?
Yes. SuperchargePerformance is designed to complement other extensions. The per-site whitelist lets you disable specific features on sites where they conflict, with one-click bypass per domain.
What data does it collect?
None. Zero telemetry, zero analytics, no account required. Your browsing history and tab data never leave your device.
What's the difference from Chrome's built-in Memory Saver?
Chrome Memory Saver only suspends tabs when memory is critically low. SuperchargePerformance adds proactive intelligent suspension with configurable timing, full ad and tracker blocking, per-site script throttling, domain whitelisting, adaptive memory-aware suspension, and 8 more optimization features — a complete performance toolkit versus a single fallback feature.
Does SuperchargePerformance work on Microsoft Edge?
Yes. SuperchargePerformance is available natively on the Microsoft Edge Add-ons store (approved May 2026). Edge is Chromium-based, so you get the exact same extension with all features: tab suspension, ad and tracker blocking, YouTube and Twitch video ad blocking, script control, and more. Install directly from the Edge Add-ons store in one click — no "allow extensions from other stores" toggle required.

Instant difference.
Every tab you have open right now is using more RAM than it needs to. One click to fix that — no account, no config.
