Slumber — Tab Suspender

Suspend inactive tabs to reclaim memory. Lightweight, private, no telemetry.

Slumber suspends tabs you are not using, freeing up memory and reducing CPU load — without compromising your privacy or your wallet. WHY SLUMBER? * 3 permissions only — tabs, storage, alarms. Nothing else. No broad host access, no history, no webNavigation. * Zero telemetry — no analytics, no tracking, no third-party SDKs. Your browsing stays on your device. * No subscription — $4.99 once for Pro. Free tier suspends up to 10 tabs with no time limit. * Your license travels with you — Pro status syncs automatically across all your Chrome devices via Chrome Sync. No account needed. * Open source — every permission and network call is verifiable on GitHub. Built on Manifest V3 — the current Chrome extension standard. Future-proof from day one. FREE TIER * Auto-suspend tabs after a configurable idle period * Manual suspend with one click * Never suspend pinned or audio-playing tabs * Up to 10 tabs suspended at once PRO ($4.99 ONE-TIME) * Unlimited tab suspension * Bulk select and suspend multiple tabs at once * Domain whitelist — specific sites that will never be suspended * Cross-device settings sync The Great Suspender was removed from the Chrome Web Store in 2021 after a change of ownership introduced malware. Slumber was built to fill that gap — with a clean codebase, minimal permissions, and full transparency. GitHub README — Trust Section Permissions: tabs, storage, alarms — nothing else. Telemetry: none. Network: the only external call is to the Slumber license server to verify your Pro key. It runs once when you activate and silently on browser startup — never for any other purpose. Data: your tab URLs, titles, and favicons never leave your device. Payments: handled entirely by Paddle. Slumber never sees your card details or email. Optional: "Support the Project" If you love Slumber and want to support future development beyond your Pro purchase, you can buy me a coffee at ko-fi.com/dkhandev. It is entirely optional and never shown to free users or during the upgrade flow.
