OneTab is the ultimate tab management extension that reduces browser memory usage by 95% instantly. Collapse all open tabs into a single list with one click, restore tabs individually or in groups, export lists as text, and share tabs as a webpage. Trusted by 2 million+ power users and researchers worldwide.
Memory Reduction: OneTab reduces browser memory usage by up to 95% by converting tabs into a lightweight list. Collapse 50 tabs using 2GB RAM into a single tab using 100MB — instant performance boost.
Chrome's tab design is notoriously memory-hungry — each tab can use 100-200MB of RAM. For researchers, developers, and power users who regularly have 30-50+ tabs open, this quickly leads to system slowdowns, fan noise, and battery drain.
For developers juggling documentation tabs, researchers with 50+ academic papers open, or anyone who says "I'll read this later," OneTab is the difference between a responsive browser and a sluggish, RAM-starved disaster.
Collapse 50 tabs (2GB RAM) into a single list (100MB). Instant performance boost — stop Chrome from killing your computer.
Click any tab in the list to restore it. No need to reopen all tabs at once. Perfect for selective reading sessions.
Restore all tabs from a specific session at once. Great for resuming work on different projects (e.g., "Marketing Campaign" vs "Bug Fixes").
Export tab lists as plain text URLs. Copy-paste into notes, emails, or project management tools. Supports import from URL lists too.
Generate a public URL containing your tab list. Share research collections, reading lists, or curated resources with colleagues.
Pin frequently-used tab groups to the top. Perfect for recurring workflows (e.g., "Morning News" or "Client Project X").

Save tab lists for backup or collaboration:
| Feature | OneTab | The Great Suspender | Session Buddy |
|---|---|---|---|
| Price | Free | Free (discontinued) | Free |
| Memory Reduction | 95% (collapses tabs) | 80% (suspends tabs) | 0% (saves sessions only) |
| One-Click Collapse | ✅ Yes | ❌ No (manual per tab) | ❌ No |
| Selective Restore | ✅ Individual tabs | ✅ Click to reload | ✅ Session restore |
| Export/Share | ✅ URLs + webpage | ❌ No | ✅ Export JSON |
| Pin Lists | ✅ Yes | ❌ No | ✅ Save sessions |
| Use Case | Tab hoarding → cleanup | Auto-suspend unused tabs | Session management |
Verdict: OneTab is best for instant RAM relief via tab collapse. The Great Suspender was superior but discontinued (malware scandal). Session Buddy is for saving/restoring sessions, not memory reduction.

Combine OneTab with other productivity tools:
OneTab closes all open tabs and saves their URLs in a list. You can restore them anytime by clicking the tab title. Think of it as "bookmarking all tabs at once."
No. OneTab stores tab lists locally in your browser. To sync across devices, export lists as URLs and import them on other machines.
No built-in undo function. However, if you export lists regularly, you can re-import from backups. This is why exporting is critical.
By default, OneTab ignores pinned tabs (they stay open). You can change this in settings: Right-click OneTab icon → Options → "Include pinned tabs."
Each tab uses 100-200MB RAM. Collapsing 50 tabs saves ~5-10GB of RAM. OneTab's list page uses only 50-100MB total.
OneTab only stores tab URLs and titles locally. It doesn't send data to external servers (except when you choose to "Share as web page"). It's safe and privacy-friendly.
