Radarr and Sonarr run background tasks constantly — scanning libraries, checking metadata, refreshing RSS feeds. ArrPower batches these into smart windows so your drives sleep when you do.
No account needed. Works in your browser. Docker-ready.
Both tools were designed for always-on servers with spinning disks. If you care about power, they're not optimized for you.
Tasks like RSS sync, metadata refresh, and download checks run every few minutes — waking your drives from sleep constantly, even at 3AM when nothing is happening.
A spinning HDD draws 6-8W more than a parked one. Multiply that by 24/7 unnecessary activity and you're paying real money for nothing. Over a year, that's $15-30 wasted.
Radarr and Sonarr let you set intervals, but not time windows. You can't say "run everything between 2-3AM" — tasks scatter randomly throughout the day and night.
A dashboard that connects to your Radarr/Sonarr APIs and gives you real control.
Define time windows (e.g., 2:00–3:00 AM) where all maintenance tasks run together. Outside those windows, tasks are suppressed. Your drives sleep the rest of the day.
See all Radarr and Sonarr scheduled tasks in one place. Manually trigger any task, or let the scheduler handle it. Full visibility into what's running and when.
Log every time a task would have woken your drive. See before/after comparisons of disk activity. Quantify exactly how much power you're saving.
Everything runs in your browser or as a Docker container on your homeserver. Your API keys never leave your network. No cloud, no accounts, no telemetry.
No Docker required for the dashboard. Just open it and paste your API keys.
Paste your Radarr and Sonarr API keys and server URLs. Everything stays local in your browser.
Choose a 1-4 hour window when maintenance should run. We recommend 2–4 AM when you're asleep and not downloading.
The dashboard shows task activity and drive wake-ups. Most users see 80%+ reduction in unnecessary disk activity within the first day.
The core tool is free. We know the self-hosting community — you'd build it yourself before paying for something basic. So we made the free tier actually useful.
Pro tier ($5/mo) adds multi-server management, historical analytics, and email/webhook alerts. But you can run a single Radarr + Sonarr setup for free forever.
