PORTABLE BROWSERS IN 2026
Portable Browsers
A portable browser runs straight from a USB drive — no installation, no trace left behind. Tabbit takes the same idea further: your bookmarks, tabs, and AI Agent follow you to any computer, no USB stick required.
Free for Windows & macOS
Why Tabbit redefines portable browsing
THE BASICS
What is a portable browser?
A portable browser is packaged so it can run directly from a USB drive, external SSD, or portable app folder instead of being installed on the host computer.
Portable software is designed for computers where you cannot or do not want to install programs — work PCs, public terminals, library machines, or a friend’s laptop. When you are done, you unplug the drive and the browser, bookmarks, passwords, and history go with you. Nothing is left behind on the computer you borrowed.
No installation
Run the browser executable from a USB drive or portable folder. No admin rights are needed on most computers.
Data travels with you
Bookmarks, passwords, cookies, and extensions live in the portable folder, so your browsing profile is always in your pocket.
Leaves no trace
When you unplug the drive, the host computer keeps no profile data, history, or settings from your session.
WHY PEOPLE GO PORTABLE
Why people choose portable browsers
The same reasons people packed a browser on a USB stick are the reasons millions now want a browser that works on any computer — and Tabbit delivers them without the hardware.
Work and public computers
Use your own browser on a locked-down work PC, library terminal, or hotel kiosk without installing anything.
Privacy and no traces
Keep your browsing history, logins, and settings out of shared machines. You decide what the browser is allowed to remember.
Your data goes everywhere
Bookmarks, passwords, and extensions travel with you, so every computer feels like your own setup in seconds.
No admin rights needed
Portable apps bypass installers and system changes, which is a lifesaver on restricted or borrowed machines.

THE AI DIFFERENCE
Tabbit turns portability into an AI workbench
A classic portable browser carries your bookmarks. Tabbit carries your bookmarks, your AI assistant, and your Agent — so the computer you sit down at becomes your own smart workstation in seconds.
AI on every page, wherever you are
Open any article, document, or dashboard and ask Tabbit to summarize, translate, or extract the key points. The AI sidebar works alongside the page on any computer — no copy-paste into a separate chatbot.
Agent Mode that executes
Describe a multi-step task and Tabbit opens its own tab group to read pages, fill forms, and move data between websites. You keep working in parallel instead of clicking through every step.
Free top AI models, side by side
Ask several leading models at once and compare their answers in one view. International users get GPT, Gemini, Claude, and more — no paid API keys needed.

FAQ
Common questions about portable browsers
What is a portable browser?+
A portable browser is packaged to run directly from a USB drive or portable folder without being installed on the host computer. Bookmarks, passwords, and settings live in that folder, so they travel with you and leave no trace behind.
What are the best portable browsers in 2026?+

Is Tabbit a portable browser?+

Do portable browsers work on Windows 11 and macOS?+

Firefox Portable is widely regarded as the cleanest, writing almost everything inside its own folder. Chromium-based portable browsers like Chrome and Brave sometimes write files to the host system. Tabbit avoids the problem differently: you sign in to your own profile and can clear local data at any time.
Can I keep my bookmarks and passwords when I switch from a portable browser?+
Yes. Tabbit imports bookmarks, passwords, history, cookies, and extensions from Chrome, Edge, and other browsers in one click, then keeps them synced across your computers.

How do I use a browser on a PC where I cannot install anything?+
Use a portable browser from a USB drive, or carry a browser that keeps your profile in sync. If the PC allows it, installing Tabbit once and signing in gives you the same data plus AI on every future computer.
Carry your browser. And your AI.
