stack is git stash for your browser. Save the tabs you're working on as a
named "stack," close the window, then bring everything back later with one
keystroke - scroll position, form data, the whole working state.

The diff view (Pro) shows what's new, what got closed, and what's still
there since you last opened the stack. A changelog for your browser.
Nothing else does this.

Free for 5 stacks forever. No card. No account. Local-first by default.
Open source-as-shipped.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHO IT'S FOR

- Developers juggling docs, GitHub issues, and Stack Overflow tabs across
multiple features
- Designers with reference boards, Figma files, and inspiration scattered
across windows
- Researchers and writers running parallel investigations
- PMs and analysts switching between dashboards, tickets, and call notes
- Trip planners, apartment hunters, thesis writers - anyone whose brain
runs in parallel projects

If you've ever opened your laptop and thought "what was I working on
yesterday?" - this is for you.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

HOW IT BEATS THE ALTERNATIVES

vs OneTab: OneTab dumps every tab into one giant list. Stack groups them by
what you were actually working on. You pick the project, not 200 forgotten
tabs.

vs Tab Groups (built into Chrome): Tab groups vanish when you close the
window. Stacks survive across sessions, devices, and machine restarts.

vs Toby / Workona: Heavyweight team workspaces that need accounts on day
one. Stack is local-first, keyboard-first, and the free tier is genuinely
free forever.

vs Bookmarks: Bookmarks save URLs. Stack saves your working state, in
order, with scroll positions and form data intact.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

PRIVACY (READ THIS)

- 100% local by default. Tab content and URLs never leave your browser.
- Optional Pro sync uses AES-GCM-256 client-side encryption. The server
only ever sees ciphertext.
- No analytics inside the extension. No ads. No tracking.
- Open source-as-shipped: vanilla JavaScript, no build step. You can read
every line by inspecting the unpacked extension.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHY DOES STACK NEED THESE PERMISSIONS?

- Tabs: To read tab titles and URLs so we can save and restore them. This
data never leaves your browser.
- Storage: To save your stacks locally (chrome.storage.local). Not synced
unless you opt into Pro encrypted sync.
- Scripting + Host permissions: To inject a content script that captures
scroll position and form state. The script runs only on your active tabs
and only writes to local storage.
- History: To detect duplicate tabs across windows for the duplicate-finder
feature.
- Identity (optional, Pro only): Used once during Google sign-in to verify
your account for sync. Not used to read your Gmail or any other Google
data.
- Alarms: Used to schedule auto-suspend of background tabs (Pro feature).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

PRICING (TRANSPARENT)

- Free: 5 stacks, forever. No card, no account, no nag screens. Genuinely
free.
- 7-day Pro trial on install. No card to start.
- Pro: $9/month or $72/year (save 33%). Unlimited stacks, encrypted sync,
diff view, auto-suspend, pinning, notes, import/export, duplicate
detection.
- Lifetime: $99 one-time, first 100 only. Everything in Pro forever,
including all future updates.

Feature-gated, not usage-gated. No daily caps. No "save up to X per day"
limits.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

KEYBOARD SHORTCUTS

- Cmd/Ctrl + Shift + S: open the stack popup
- Type: fuzzy search across all stacks
- Up/Down arrows: navigate the list
- Enter: open the highlighted stack
- Tab: save the current window as a new stack
- Esc: close the popup
Designed to be used without a mouse.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

FAQ

Q: What happens to my tabs' scroll position and form data?
A: Saved and restored with the stack. Half-written messages, scroll
location, form state - it all comes back.

Q: Can I use it across multiple computers?
A: Yes, with Pro encrypted sync. Your stacks sync across devices using
AES-GCM-256 encryption. The server never sees plaintext.

Q: What if I cancel Pro?
A: Your stacks stay. You drop back to the free tier (5 stacks). Your
existing stacks are not deleted; the cap only blocks creating new ones.

Q: Does it work with Tab Groups?
A: Yes. Stack saves the tabs in order; tab groups themselves are not
preserved (yet).

Q: Will this work on Firefox or Edge?
A: Edge yes (Manifest V3 compatible). Firefox port is on the v3.0 roadmap.

Q: Do you train AI on my tabs?
A: No. Tab content never leaves your browser. There's no server-side
processing of your data. Period.

Q: Is the source code open?
A: Source-as-shipped: there's no build step, no transpiler, no bundler. The
code that runs is the code in the extension folder. You can read every
line.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHAT'S NEW IN v2.1.1

- Post-checkout welcome page with a 3-step setup checklist (sync,
encryption password, auto-suspend) so Pro is doing real work for you from
day one.
- Clicking a Pro feature as a free user now opens a clear explainer instead
of a brief popup.
- Trial expiry banner shows clear urgency in your last 2 days.
- Smoother handoff between popup and settings page when upgrading.

Stack saves your browser tabs as named working sessions - and lets you restore them instantly.

You're deep in research, planning a trip, or juggling three projects at once. You've got 20 tabs open and they all matter. Then something else comes up. You either pile more on top or close everything and lose your place.

Stack fixes that. One keyboard shortcut saves everything as a named stack. Type the name later to bring it all back - every tab, every scroll position, right where you left off.

HOW IT WORKS

1. Hit ⌘⇧S (or Ctrl+Shift+S) to open the save panel
2. Name your stack — "trip-planning", "Q2-sprint", "thesis-research"
3. Your tabs are saved and the window closes
4. Open Stack anytime, type a few letters, hit enter — everything restores

That's it. No complicated setup. No account required

FEATURES

✦ Tab Session Manager — Save and restore complete tab sessions with one click
✦ Named Workspaces — Organize tabs by project, topic, or context
✦ Fuzzy Search — Find any tab across all saved workspaces instantly
✦ Diff View — See what tabs were added, removed, or changed since your last session
✦ Tab Management — Delete, rearrange, and organize tabs before restoring
✦ Keyboard-First — Full keyboard navigation, no mouse required
✦ Memory Saver — Close unused tabs to free up RAM and CPU
✦ Privacy-First — 100% local storage, no data leaves your browser
✦ Manifest V3 — Built on the latest Chrome extension platform

WHO IT'S FOR

→ Developers switching between projects and documentation
→ Researchers managing multiple topics and sources
→ Students juggling coursework, references, and assignments
→ Anyone with too many tabs who needs a better tab organizer

STACK vs TAB GROUPS

Chrome's built-in tab groups don't survive a browser crash, can't be searched, and don't show you what changed. Stack does all three.

Think of it as git stash for your browser.

FREE & PRO

Free: Up to 5 saved stacks, full search, keyboard shortcuts
Pro: Unlimited stacks, diff view, tab management, priority support

7-day free trial of Pro on install. No credit card required.
