💤 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).
Tabs you care about (like music players or docs) can be whitelisted so they never go to sleep.
✨ Key Features
🌙 Smart Auto-Sleep — suspends inactive tabs to save memory
🛡️ Whitelist Support — protect important tabs from suspension
📊 Live Dashboard — see which tabs are active, sleeping, or whitelisted
⚡ Fast Under the Hood — LRU cache in WebAssembly = blazing performance
🔒 Privacy First — no tracking, no external data, no nonsense
💡 Perfect For:
Developers juggling dozens of tabs
Students deep into research
Anyone tired of a laggy browser
