Tab Weight Visualizer

Find forgotten tabs wasting your browser memory. Sort, freeze, sleep them in one click. Real-time, all data stays on this device.

Tab Weight Visualizer ranks your open tabs by how long they've been sitting idle, so you can spot the ones that are wasting memory in the background and freeze them in one click. Stop losing tabs in the noise. Most browsers let you have hundreds of tabs open, but give you no way to see which ones are still relevant. Tab Weight sorts your tabs by idle time, color-codes them (green = fresh, yellow = stale 30+ minutes, red = cold 2+ hours), and gives you a single button to put them to sleep. Your tab list updates in real time as you switch between tabs — no refresh, no polling. WHAT IT DOES • Idle-time ranking — see at a glance which tabs haven't been touched in the longest time • Sort by oldest, newest, or title (A→Z / Z→A) • Filter by minimum idle time — 1 min, 5 min, 30 min, 1 h, 2 h • Search by title or domain — type "figma" to find your Figma tabs, "github" for open GitHub PRs • One-click Freeze — uses Chrome's native tab discarding to free memory without closing the tab • "Sleep all" — freeze every tab that's been idle for at least N minutes, in one action • Light, dark, and system theme • English and Ukrainian out of the box • Real-time updates — event-driven, no polling • Works on every Chrome channel: stable, Dev, Canary, Beta
