Nestab

About

Save and restore your browser tab workspaces in one click. No more lost sessions, no more tab chaos.
─────────────────────────────────────────
If you work across multiple projects, research sessions, or client workspaces, you know the pain: 20+ tabs open, context-switching means losing everything, Chrome crashes and takes your whole session with it.
Nestab fixes this. Name a workspace, save it, close everything. Come back tomorrow and restore it in one click — exactly as you left it.
No account required. No data ever leaves your device.
─────────────────────────────────────────
CORE FEATURES
─────────────────────────────────────────
► SAVE & RESTORE WORKSPACES
Capture all your open tabs as a named workspace with a single click. Restore them later in a new window or replace your current tabs — exactly as you left them.
► SMART AUTO-NAMING
Nestab reads your open domains and suggests a workspace name automatically (e.g. "GitHub · Figma · Notion"), so you spend zero time on organisation.
► CRASH RECOVERY
Nestab takes an automatic snapshot every 5 minutes. If Chrome crashes or tabs are lost, you'll be prompted to restore your last session instantly.
► SEARCH YOUR WORKSPACES
Find any saved workspace in seconds by name or domain. No scrolling, no digging.
► PIN, DUPLICATE & RENAME
Keep your most-used workspaces pinned at the top. Duplicate a session with one click, rename inline — no modals, no friction.
► DRAG & DROP REORDERING
Organise your workspaces exactly the way you want them.
► SMART SAVE BANNER
When you have 8 or more tabs open and haven't saved recently, Nestab gently reminds you to save — before it's too late.
► AUTO-SAVE
Set Nestab to silently save your current session at regular intervals (15 min / 30 min / 1 hour) — no manual action needed.
─────────────────────────────────────────
SYNC & BACKUP (v1.2)
─────────────────────────────────────────
► CROSS-DEVICE SYNC
Optionally enable Chrome account sync to access your workspaces on any device where you're signed into Chrome.
► EXPORT & IMPORT
Full JSON backup of all your workspaces. Export in one click, import anytime. No lock-in, ever.
► DARK MODE
Follows your OS preference automatically. Works in light and dark mode out of the box.

100% PRIVATE — ZERO DATA COLLECTION
─────────────────────────────────────────
Nestab is built with privacy as a core principle, not an afterthought.

No external servers — Nestab has no backend, no API, no cloud infrastructure
No analytics or tracking — zero SDKs, zero beacons, zero telemetry
No account or sign-up required
All workspace data is stored locally on your device using chrome.storage.local
Only the minimum permissions needed: storage, tabs, alarms, windows
Nestab never reads your browsing history, never touches your bookmarks, never intercepts network traffic

Your data is yours. Full stop.
─────────────────────────────────────────
WHO IS NESTAB FOR?
─────────────────────────────────────────
Nestab is built for anyone who works with multiple contexts in Chrome:

Developers juggling multiple projects or clients
Researchers and students managing topic-based reading sessions
Designers switching between design tools, references and inspiration boards
Product managers tracking multiple products or roadmaps
Freelancers managing sessions per client
Power users who simply hate losing their tabs

If you've ever had to re-open 15 tabs from memory after a crash, Nestab is for you.
─────────────────────────────────────────
TECH STACK & COMPATIBILITY
─────────────────────────────────────────

Built on Chrome Extension Manifest V3 — the current and long-term supported standard
Pure vanilla JavaScript — no frameworks, no build step, instant load
Service Worker background — MV3 compliant, minimal memory footprint
Compatible with Chrome and all Chromium-based browsers

─────────────────────────────────────────
PERMISSIONS — AND WHY
─────────────────────────────────────────
Nestab requests only what it strictly needs:
storage — to save and retrieve your workspaces locally
tabs — to read the URLs and titles of your open tabs when you save a workspace
alarms — to schedule periodic snapshots and auto-save intervals
windows — to open workspaces in a new browser window when restoring
Nothing else. No host permissions. No access to your browsing history.

OPEN SOURCE & FREE
─────────────────────────────────────────
Nestab is free to use, MIT licensed, and fully open source. If it saves you time, a coffee is always appreciated — but never required.
