It’s a browser extension that turns groups of tabs into one-click workspaces, so instead of manually opening GitHub, docs, and localhost every time I sit down to code, I click one card and they all open together. The feature I actually care about is the friction timer: tag a workspace as Entertainment and it makes you sit through a 10-second countdown with an “Actually, I’ll work” button before it lets the tabs open. Everything’s built in vanilla HTML, CSS, and JS with the WebExtensions tabs API, no backend, no accounts, just the browser’s local storage so nothing ever leaves the device. Most of the time went into getting tab capture right so it grabs whatever’s currently open without duplicating tabs that are already saved in a workspace.
