Dormant

Auto-suspends inactive tabs to save RAM

Dormant automatically suspends inactive tabs to free up RAM and keep your browser fast. Key features: — Auto-suspends tabs after a configurable inactivity threshold (5–120 minutes) — Whitelist domains you never want suspended (e.g. github.com, notion.so) — See exactly how many tabs are suspended and estimated MB saved — Restore any suspended tab instantly with one click — Works silently in the background — no setup needed How it works: Dormant uses Chrome's native tab discarding (chrome.tabs.discard) — the same method Chrome itself uses when memory is low. No custom suspend pages, no redirects. Just clean, native memory management. Privacy: Dormant stores nothing remotely. Your whitelist and settings live only in your browser via chrome.storage. No analytics, no tracking, no account required. Open source. Built with React, TypeScript, and Vite on Manifest V3.
