💤 NapTab — Automatically Put Inactive Tabs to Sleep
Too many tabs? Chrome getting sluggish?
NapTab automatically suspends tabs you haven’t used in a while, so your browser stays fast and your memory stays free.
No need to close anything — just keep browsing. We’ll handle the rest.
🔧 How It Works
NapTab uses a custom-built memory manager powered by C++ and WebAssembly for super fast tab tracking. It quietly suspends the least recently used tabs when you go over your set limit (default is 10).
