Polyshell Browser
Isolated profiles for multi-account browsing.
What it does
Tired of messy logins, cookie mix-ups, and wrong proxies? I built Polyshell Browser — a clean, privacy-first iOS browser with fully isolated profiles for serious multi-account users. Each profile has its own cookies, sessions, User-Agent, and proxy settings. Switch instantly, share across iPhone & iPad, and keep work, stores, and ads completely separate. Perfect for ecommerce sellers, marketers, and power users who need real isolation without the chaos. Free to start with multiple workspaces

- IMI made a customizable iOS browser for minimalists and myself2023 · apps.apple.com · ▲226
Hello HN! So early this year I decided to build an iOS browser offering a large range of customization options, to accommodate anyone’s usage and visual preferences. Been using it as my default browser for 6 months and not looking back. On first launch it looks and behaves a bit like Safari, but to give you an idea, here are the various ways I customized it on my phone. - More screen real estate for the webpage, less for the toolbar. - A compact toolbar containing only the buttons for actions I use the most: new tab, close tab, open tab list. Since I use them hundred times a day, I need them…

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!

Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands. So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else: - Buy exactly the weeks you need. Three nodes for the last…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
