Popup, not a tab · AI clustering · Firefox & Chromium browsers

Stop losing your
browser sessions.

SeshTab saves every tab, every window, every session — then brings them back exactly how you left them. A popup, not a browser tab — close it and memory drops to zero.

The Problem

You've been there.

Three moments every tab hoarder knows — and why they stop with SeshTab.

01

The crash

Chrome updates. System restart. 47 tabs gone, hours of context — vanished.

02

4 GB of tabs

You know you should close them. But closing means forgetting. So you don't.

03

No project switching

Work, side project, research, shopping — all mixed in one chaotic tab bar.

The Transformation

Chaos → clarity, as you scroll.

Every tab below is a real context you're juggling right now. Watch them organize themselves into SeshTab as you scroll.

Features

Everything a power user needs.

Built for people who live in the browser. Every feature earns its keep.

Workspaces that actually stay organized

Group tabs by project. Close them to free RAM instantly. Reopen with one click — same tabs, same scroll, same everything. Color-coded, searchable, synced.

Cloud sync PRO

Sessions backed up in real time. Never lose work after a crash, reinstall, or switching machines.

Tab snooze

Hide a tab and schedule it to reappear exactly when you need it. No noise, no notifications.

Command palette

⌘⇧K to search all open tabs, workspaces, and snoozed tabs instantly. Keyboard-first.

AI clustering PRO

gpt-4o-mini silently groups your tabs by topic. No setup, no prompts — just one tap to organize a hundred tabs in seconds.

Private by default

Free tier is 100% local — nothing leaves your device. Pro uses row-level security with encryption in transit.

Performance

The only tab manager that isn't a tab.

Other tab managers open a browser tab that uses 41–105 MB all day. SeshTab is a popup — open it with Ctrl+Shift+K, use it, close it. No open tab, no background overhead.

Loved by tab hoarders.

Finally replaced Workona. Twice as fast and half the price. My MacBook fan is quieter.

The command palette alone is worth it. I open it more than my browser bar now.

FAQ

Honest answers.

Will SeshTab slow down my browser?
No. The background script sleeps when inactive. It uses a fraction of Workona's memory — we benchmark publicly.
Is my data safe in the cloud?
The Free tier is 100% local — nothing leaves your device. Pro uses Supabase with row-level security and encryption in transit.
OneTab is free. Why pay for Pro?
OneTab has no cloud sync and has caused data loss after browser updates. Pro backs up your sessions in real time, across devices.
I've installed 5 tab managers and abandoned them all.
SeshTab shows you value before asking for an account. Install, save your first workspace in 60 seconds, then decide.
Is AI actually useful here, or just marketing?
It groups your tabs by topic on demand. You can ignore the feature entirely — the product is still worth it without it.
Which browsers are supported?
Chrome, Edge, Arc, Brave, and any Chromium-based browser. Firefox is also supported.
