SuperchargeBrowser vs Auto Tab Discard: 2026 Review
SuperchargeBrowser vs Auto Tab Discard: 2026 Review

Auto Tab Discard (ATD) is a respectable, open-source extension that popularized the `tabs.discard` API. However, it suffers from "Engineer"s UI" syndrome. It is highly configurable but overwhelmingly complex for the average user, requiring regex knowledge for proper whitelisting, and it lacks any network-level optimization tools.

Competitor Weaknesses
- Dated UI: Options page is a wall of text and checkboxes.
- Single Purpose: Only handles suspension; does not block ads or stop trackers.
- Configuration Friction: Whitelisting requires manual domain entry or regex.

Architecture Comparison
Both extensions utilize the underlying chrome.tabs.discard API, meaning the mechanism of freeing memory is identical. The difference lies in the Trigger Logic and the Ecosystem.
The Friction Factor
ATD requires you to understand browser lifecycle states to configure it correctly. If you get it wrong, you lose tabs. SuperchargeBrowser abstracts this complexity. We use a "Human-First" logic: if you are playing audio, if you are pinning a tab, or if you are filling a form, we know not to touch it.
Feature Density
ATD fixes one problem: RAM. But RAM is only half the equation. If a tab is loaded with ads, it drains battery even if you have plenty of memory. SuperchargeBrowser fixes the Root Cause (blocking the bloat) and the Symptom (suspending the tab). You would need to install ATD + uBlock Origin + a Script Blocker to match the functionality of a SuperchargeBrowser installation.
