Tabby — Smart Tab Memory Manager

Automatically sleeps inactive tabs based on real RAM usage — keeping Chrome fast without relying on fixed timers.

Too many tabs open? Your browser is probably struggling with RAM — and Chrome's built-in fix isn't helping. Tabby automatically sleeps inactive tabs based on real RAM usage — not fixed timers. Unlike Chrome's built-in Memory Saver, Tabby reacts to actual memory pressure and only acts when your browser truly needs it. No setup required. Install once and let Tabby manage your tabs automatically in the background. Why Tabby? Chrome's built-in Memory Saver relies on inactivity timers. This means tabs can be suspended even when your system has plenty of available memory. Tabby takes a different approach. Instead of using fixed timers, Tabby continuously monitors your system's memory usage and only steps in when memory pressure increases. This helps keep your browser responsive while minimizing unnecessary tab sleeping. Why not just use Chrome Memory Saver?
