An effective niche tool for anyone who lives in the browser: it sandboxes and organizes web apps, at a gentle price, without reinventing how you use them.

WebCatalog is a suite of desktop tools for taming web applications. Its idea: turn a site or web app into an isolated desktop application, and organize everything into spaces and profiles, for anyone juggling dozens of online services.
The main building block, WebCatalog Desktop, opens each web app in its own sandboxed window, with separate profiles (multiple Gmail accounts at once without logging out, for instance). Atlas (a start page), Singlebox (messaging apps combined), and Switchbar (choosing a browser per link) round out the suite. The goal is to pull web apps out of tab clutter and cleanly separate work and personal use.
It's a niche tool, but a well-made one, for power users, multi-account freelancers, and anyone who lives in the browser all day. It doesn't replace these applications, it puts them in order. On mobile, the offering is marginal: the core product is the desktop, on macOS, Windows, and Linux.
The Basic plan is free, limited to 2 desktop apps, 1 space, and 2 profiles. The Pro plan costs $5/month billed annually (unlimited apps, spaces, and profiles, cloud backup, ad blocker), and the Business plan at $8/month billed annually adds shared spaces and team management. A 7-day trial covers the paid plans.
