> OneTab closes your tabs and destroys session layout. Tab suspension keeps 40+ tabs in place with the same RAM savings: no restore clicks, no layout lost.

> **Key takeaways**
> - OneTab frees memory by **closing tabs into a URL list**. Your session layout is gone until you manually restore each one.
> - SuperchargePerformance suspends tabs in place: **same near-zero memory footprint**, every tab stays visible in the bar.
> - **No list to manage, no session context lost.** Click a suspended tab and it reloads in place.

If you've ever closed 40 tabs with OneTab and then spent ten minutes hunting for the one URL you actually needed — that's the core tradeoff. OneTab collapses your tabs into a saved URL list and closes them. SuperchargePerformance keeps every tab in the tab bar while freeing its memory via Chrome's discard API. Same RAM savings, completely different session experience.

## Feature Comparison

| Feature | SuperchargePerformance | OneTab |
|---------|----------------------|--------|
| Tab suspension | Yes — tabs stay visible, memory freed | Closes tabs, saves URL to list |
| Restoration | Click tab to reload in place | Manual click per tab, full page reload |
| Ad blocking | Yes (declarativeNetRequest) | No |
| Tracker blocking | Yes | No |
| Script blocking | Yes | No |
| Memory-saved estimate | Yes (session total) | No |
| Tab groups support | Yes | No (still no group support as of v2.14, March 2026) |
| Open-source | No | No |
| Cloud sync | No (local only) | No |
| Cost | Free core, optional PRO | Free |
| Install base | Active | ~2M users, ~4.4 stars |

## How Each Approach Works

**OneTab** uses a "destructive" model. When you click the OneTab icon, it closes all open tabs and saves their URLs to a local HTML list page. To resume browsing, you open the list and click each URL individually, triggering a full network reload for each tab.

**SuperchargePerformance** uses the `chrome.tabs.discard()` API. The tab remains visible in the browser's tab bar with its favicon and title intact. Its memory footprint drops to near zero. Clicking the tab reloads it from the network, but the visual presence is maintained throughout — no separate list page, no manual tracking of what was open.

## Workflow Impact

Once you collapse into OneTab, that visual session is gone. You lose the spatial context of what was open, what order things were in, and where you were. Restoring a session means manually identifying and clicking each URL from a flat list.

SuperchargePerformance keeps your tab bar intact. Suspended tabs sit in place with their favicon and title — the session structure is preserved. Audio-playing tabs, pinned tabs, and tabs with unsaved form inputs are never suspended.

## Privacy Comparison

SuperchargePerformance makes zero outbound network requests. No `fetch()`, no `XMLHttpRequest`, no `sendBeacon` anywhere in the codebase. All suspension logic, blocking rules, and metrics run locally. The PRO flag is a plain boolean in local storage — no remote verification.

OneTab is closed-source. Its URL list is stored locally, but you can't verify how it handles data without seeing the source code.

## Who Should Choose What

**Choose OneTab** if you want a simple, manual way to temporarily clear your tab bar and don't mind rebuilding your session manually when you return.

**Choose SuperchargePerformance** if you want automatic suspension that preserves your session structure, combined with ad blocking, tracker blocking, and visibility into how much RAM you're saving.

## Bottom Line

OneTab is fine if you don't mind losing your session layout and rebuilding it manually. If keeping that context is important to you, it's the wrong tool — you'll be frustrated by it within a week. SuperchargePerformance solves the same RAM problem without destroying the session.
