SpeedBoost – Free Up RAM, Sleep Tabs & Speed Up Chrome

See what slows your browser and fix it in one click: sleep unused tabs, close duplicates, clear cache and free up memory. Free.

Is your browser getting slow with too many tabs open? SpeedBoost shows how full your computer's memory is and fixes it in one click. WHAT IT DOES • A coloured badge on the toolbar shows how much memory is in use: green, yellow or red. • See the tabs that weigh the most and put them to sleep or close them right from the popup. • One "Speed up" button: puts unused tabs to sleep, closes duplicate tabs and, if you want, clears the cache. • You always see exactly what will happen before anything changes. • After every clean-up SpeedBoost measures how much memory was actually freed. No made-up numbers. SLEEPING TABS ARE SAFE Sleeping tabs stay exactly where they are. Click one and it reloads. Pinned tabs, tabs playing audio and sites on your protected list are never touched. OPTIONAL AUTO MODE Turn on automatic sleep in settings and choose after how long an unused tab should sleep: 15, 30, 60 or 120 minutes. PRIVATE BY DESIGN • Everything happens on your computer. SpeedBoost has no servers and sends nothing anywhere. • No account, no tracking, no ads. • Measuring which tabs are heaviest is optional. SpeedBoost only asks for access to pages when you click "Find the heaviest tabs". Free. Available in English and Lithuanian.
