Sidekick Browser is designed to replace your everyday browser with a productivity system centered on
sessions, workspaces, and a pinned “apps” sidebar. Where WebCatalog shines at creating discrete desktop-style apps, Sidekick focuses on reducing tab chaos inside a single, streamlined browser experience.
Sessions are the core differentiator: instead of keeping 50–100 tabs perpetually open, Sidekick helps save, close, and restore full contexts on demand. This can meaningfully cut cognitive load and improve performance by keeping only the current work set active.
The pinned-app sidebar is the other big win, keeping frequently used tools always available without clogging the tab bar. Combined with split view, tab search, and built-in blockers, it aims to replace a pile of extensions with native workflows that stay consistent across projects.
It’s best when the goal is focus and organization rather than “one app per service” separation, and it can be a better fit for knowledge workers who live in the browser all day.
