The browser workspace for minds that move fast.
Say goodbye to chaotic tab sprawl and fake memory meters. Tabs Stack delivers disciplined spatial organization, sub-50ms local IndexedDB persistence, 1-click surgical collapse, and 100% on-device privacy.
The browser interface you wish Chrome had built.
Switch spaces, organize folders with zero-latency drag, and discard sleeping tabs honestly with native Chromium suspension.
Built for engineers, researchers, and power users.
Every detail of Tabs Stack is engineered to respect your computer's memory and your mind's focus.
Surgical 1-Click Collapse & 15s Undo
Collapse your entire window, selected tabs, or native Chrome tab groups into timestamped Session folders. Made a mistake? A 15-second undo toast restores every tab in its exact order.
Honest Memory Discard
Unlike extensions that claim to "save 4.8 GB of RAM" with fake charts, Tabs Stack triggers native Chromium tab suspension (tabs.discard) safely while exempting audible tabs and pinned tabs.
Sub-50ms Local-First Persistence
Your tabs, hubs, and history are stored directly in your browser's IndexedDB engine via Dexie.js. Zero network tracking, zero third-party analytics, and unlimited local hubs and tabs on every plan.
eTLD+1 On-Device Site Clustering
Group tab chaos into neat clusters by site automatically. Features a lightweight built-in multi-part TLD resolver (co.uk, com.au, co.jp) that sub-clusters busy hosts like GitHub repositories and Google Docs.
