A site-specific browser (SSB) is a dedicated app built to run a single website or web app in its own focused, isolated environment. Instead of sharing tabs, extensions, cookies, and distractions with everything else in your main browser, an SSB gives each service its own clean space that feels and behaves like a desktop application.

As more of your daily work has moved to the web — email, CRM, project management, dashboards, AI tools — the SSB approach has become the standard way many services deliver fast, consistent desktop apps. Slack, Microsoft Teams, Notion, and Linear all use this model. They bundle their web apps inside a dedicated browser so they can offer a reliable, app-like experience without building separate software for every operating system.

WebCatalog Desktop brings this same technology to every site you use. It turns any website into its own site-specific browser with isolated cookies, storage, and settings. That means no account conflicts, no cross-site interference, and no mission-critical tools buried in a sea of tabs. Each app becomes a stable, always-available workspace you can pin to your dock or taskbar — fast to launch, easy to manage, and tuned for focus.
