24 alternatives to I built a small utility that handles multiple browser instances for you

I'm a consultant and I normally deal with multiple clients. I need an isolated browser for each to maintain my sanity. I could create separate profiles in Chrome and Firefox but the main issue is when you click on a link outside of the browser (e.g. in your IDE), in which profile should it be opened? I wrote a Python script that redirects URLs to the correct browser instance and set it as my default browser. Over time, the script has grown and become essential to my work. I cleaned it up and open-sourced it. Hope that someone else may find it useful too!

This utility manages multiple isolated browser instances for users who need to keep work separated across different contexts. Built by a consultant handling multiple clients, it routes URLs from external applications… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I built a small utility that handles multiple browser instances for you launched in 2024; newer entries below may have overtaken it.

    Hi HN, I'm excited to share my open source project, a browser orchestrator. It's purpose is to make it easy to manage many browser profiles on one system. Currently it only works on MacOS, but since I've built it using Tauri (which is a Rust backend and TypeScript frontend), I expect to add Linux and Windows support in the future. I've built it primarily for myself as I use a lot of browsers and having an easy way to manage all of my profiles would make (have made, actually) my dock less cluttered haha. Also, part of why I built it is because as someone who doesn't really care about…

    Hey HN, I'm Zach, founder of Portal. Portal lets you share a live sandbox browser session as a link. Try it here: https://www.makeportals.com/try Instead of asking someone to sign up, install software, or book a demo for user research, onboarding, or sales, you send a link and they interact with the real product in a sandboxed browser environment, then you get session replays. Each viewer gets a fresh remote browser instance that starts from a defined state (URL, cookies, extensions, local files, etc). Sessions are isolated and expire automatically. The sessions have…
