I built a multi-account browser to solve scaling problems in online marketing

Over the past Years, I kept running into the same problem while working on online marketing projects:

Managing multiple accounts safely was becoming messy and unreliable.

Every time I tried to scale campaigns, I faced issues like:

• accounts getting linked or flagged

• constant login/logout switching

• proxy setup complexity

• inconsistent browser fingerprints

So I decided to build a tool to simplify this workflow.

I built a multi-account browser that focuses on isolation and control.

What it does:

• each account runs in a separate isolated profile

• proxy can be assigned per profile

• browser fingerprint is separated per session

• supports managing multiple accounts from one dashboard

Why I built it:

I didn’t want a “feature-heavy tool”, I wanted something focused on solving one core problem:

helping marketers scale accounts without losing control of them

What I learned so far:

• simplicity matters more than features

• users care about outcomes (not tools)

• “account safety” is a real pain point in performance marketing

It’s still early, and I’m actively improving it based on feedback.

Would love to hear thoughts from others who deal with multi-account workflows or scaling challenges.

Happy to share more technical details if anyone is interested 👍
