About Sleepy Tabs Guardian
Sleepy Tabs Guardian
Sleepy Tabs Guardian keeps Chrome lean without losing your place. Automatically pause idle tabs, act on runaway memory, and review every decision in a searchable dashboard. In-page reminders give you the final say—snooze, ignore, sleep, or reload—while an optional native helper deepens telemetry.
Features:
- Auto-sleep inactive tabs after a configurable timeout (default 5 minutes) with per-tab override switches.
- Auto-manage high-memory tabs with per-state actions (default total heap threshold 100 MB, reminder for active tabs, sleep for inactive) using CDP lifecycle commands.
- IndexedDB-powered telemetry log with dashboard highlighting critical pages and recent actions.
- Consent workflow plus in-page reminders with countdowns that auto-accept actions if the user is away.
- Options page for thresholds, reminder timers, and automation toggles.
- Hybrid telemetry stack.
What's new in 0.1.3:
- Smarter idle reminders that respect Chrome/Edge privileged pages yet still capture tab state at startup.
- One-click "Restore defaults" on the Options page for fast recovery after experiments.
- Refined documentation and onboarding guidance for administrators rolling out the extension at scale.
Key capabilities:
- Configurable inactivity timeout with per-tab ignore toggles.
- Memory thresholds with separate actions for active vs. inactive tabs.
- Rich telemetry stored locally in IndexedDB and surfaced in a side-panel dashboard.
- Optional native companion (via Chrome Native Messaging) to stream Chrome DevTools Protocol metrics when deeper insight is required.
