Browser Isolation Manager – Run Every Account in Its Own Sandboxed Browser Window
Hey PH! 👋
I'm an independent developer and software engineer from China. I spend most of my time building practical tools with Python and Chrome extensions — solving real problems I run into during work and daily life. This is my fourth Chrome extension, and like the others, it was born out of a personal need.
If you've ever managed multiple accounts on the same website, you know the drill:
Log out of one → log into the next → repeat. Every. Single. Time.
Some extensions try to fake isolation through "profiles," but they're fragile, browser-specific, and often break when you least expect it.
So I built a better way.
What is Browser Isolation Manager?
A Chrome extension that launches every account login inside its own sandboxed browser window — each with completely independent cookies, sessions, and data. Zero conflicts. Zero cross-contamination.
Who is this for?
Sellers juggling multiple store accounts
QA testers verifying different user roles
Social media managers handling 5+ brand accounts
Freelancers with separate client logins
Anyone who's tired of the login-logout dance
What you can do
Launch an isolated browser for any URL in one click
Name each profile and reuse the same login state anytime
Watch live status: running, PID, start time
Restart, stop, or delete any process — even all at once
Everything persists, so your setup reloads on next start
How it works
A tiny local backend (Python + Flask) starts each Chrome window with its own independent profile directory. The extension panel gives you full control — start, stop, restart, or delete any isolated window instantly.
No cloud, no tracking, no account data ever leaves your machine.
Privacy First
No personal data is collected, stored, or sent anywhere
No analytics, no telemetry
All data stays local on your device
Built for real multi-account work
Whether you run an online store, test sign-up flows, or manage five brand accounts at once, this tool keeps every identity cleanly separated — and switchable in seconds.
I built this because I needed it myself. Now I'm sharing it with all of you.
If you juggle multiple accounts, give it a try. And if you have feedback, feature requests, or bug reports — I'm all ears. Drop a comment or DM me anytime.
Thanks for reading! 🙏
