TabChill — Freeze Tabs & Boost RAM

Freeze idle background tabs in 1 click, save up to 80% RAM, clean duplicate tabs, and stash workspaces safely.

Keep all your tabs open without your computer slowing down, freezing, or overheating. TabChill is a lightweight, local-first browser extension that safely puts idle background tabs to sleep. It frees up to 80% of your browser's RAM immediately, while keeping every tab in your tab bar. The moment you click back into a sleeping tab, it wakes up right where you left off. 🛡️ Safe, Reliable & Stress-Free: • Zero lost work: Tabs never disappear or close on their own. They stay visible in your tab bar and restore instantly the millisecond you click them. • Music and calls stay awake: TabChill automatically detects and protects tabs playing audio or video (Spotify, YouTube, Zoom, Google Meet). • Pinned tabs protected: Keep your daily tools always loaded and never put to sleep. • 100% private in-browser: Operates entirely on your device. No telemetry, no cloud servers, and zero browsing data leaves your machine. ⚡ Key Features: 🧊 1-Click Deep Sleep Put all background tabs to sleep in a fraction of a second. Free gigabytes of memory before running code, games, design software, or heavy applications. 📊 Live RAM Reclaimed Meter See exactly how many megabytes and gigabytes of RAM you have saved in real time. 🧹 Merge Duplicate Tabs Detects repeated URLs across open windows and cleanly merges them into one, keeping your primary active tab intact. 📁 Workspaces & Session Stashing Save entire research sessions or client project tabs into named collections. Close them to free your mind, and restore them anytime with 1 click. ⏱️ Automatic Inactivity Timer Choose to automatically put idle tabs to sleep after 15 minutes, 30 minutes, or 1 hour, or add trusted domains to your whitelist so they never sleep.
