How it works

Simple, smart, and automatic.

Tabby runs quietly in the background. No setup needed. Just install and let the cat do its job.

Install Tabby

One click. No account. No permissions beyond what's needed. Ready immediately.

Tabby watches your memory

The cat companion shows your browser's health in real time — happy, tired, or stressed.

Idle tabs go to sleep

Tabs you haven't touched are gently rested. They reload instantly when you need them back.

Your browser stays fast

Less memory pressure. Smoother browsing. A happier cat — and a happier you.

Features

Everything your browser needs. Nothing it doesn't.

Lightweight, private, and does exactly what it promises.

Mood-Based Companion

Tabby's mood changes based on your browser's memory pressure. Happy and bouncing when calm. Stressed when things get heavy.

Smart Tab Sleeping

Tabby waits until tabs are truly idle before putting them to sleep. No aggressive discarding — just gentle, intelligent resting.

Protects What Matters

Active tabs, pinned tabs, and tabs playing audio are never touched. Music, calls, and podcasts keep running. Add your own sites to the whitelist too.

Daily Insights

See tabs slept and memory reduced today. Resets every morning so you always know what Tabby did for you.

Fully Customizable

Private & Lightweight

Zero browsing data collected. No servers. Runs only when your browser is open. Your tabs and history stay completely private.

Intelligent Autopilot

Tabby checks more frequently when your browser is stressed and slows down when things are calm — saving resources while staying responsive.

Auto RAM Detection

Tabby automatically scans your system memory and sets smart default thresholds based on what your device can actually handle — no manual setup needed.

Manual Sleep Button

Three states. Three behaviors. Always adapting to keep your browser healthy.

FAQ

Questions answered.

Will Tabby close my tabs permanently?+

No. Tabby puts tabs to sleep — they stay in your tab bar and reload instantly when you click them. Nothing is ever permanently closed or lost.

Which tabs are protected from sleeping?+

Active tabs, pinned tabs, tabs playing audio, and any sites you add to your protected list are never put to sleep. Your calls, music, podcasts, and docs are always safe.

What's the difference between autopilot and the sleep button?+

Autopilot is gentle — it waits for tabs to be idle and protects audio tabs so your music never stops. The "Put Tabs to Sleep" button is the emergency override: it acts immediately and clears everything it can, including paused media, to free memory as fast as possible.

Does Tabby collect any of my browsing data?+

Absolutely not. Tabby collects zero browsing data. Everything runs locally in your browser. Your tabs, history, and activity are never sent anywhere.

Does it work on Edge and Brave?+

Yes! Tabby works on all Chromium-based browsers — Chrome, Microsoft Edge, Brave, Opera, and Vivaldi.

Why is my cat stressed?+

Your browser memory is running high! Click "Put Tabs to Sleep" to help Tabby relax, or let autopilot handle it. Tabby will calm down once memory pressure drops.

Your data stays yours.
