Castra is the browser side of Castra, a workspace launcher for Windows. VOLUME MIXER FOR EVERY TAB Click the Castra icon to see every tab that is playing sound. Turn any of them up or down, mute it, or jump straight to it. The mixer works on its own, with no setup. VOLUME ON TOP OF THE SITE'S OWN Castra's volume multiplies the page's own volume: a player at 50 % with Castra at 40 % plays at 20 %. Turn a loud stream down without touching the page. WITH THE CASTRA APP FOR WINDOWS Castra opens your apps and websites, each on its own display, exactly where it belongs, in one click. For the websites, this extension adds: • Volume per workspace: saved in Castra and applied every time the page loads. • Zoom that sticks: each workspace keeps its own zoom, even after a browser restart and even for two workspaces on the same site. • Auto sign-in: once your browser has filled in your saved password, Castra presses "Sign in" for you. The extension only checks that the field is filled. The password is never read, stored or sent. • Close all: Castra closes the tabs its workspaces opened.
