UpSnap is a simple Wake on LAN app written with SvelteKit, Go, PocketBase and Nmap. Discover all devices on your Network by scanning it with just one click. You can easily set timed wake and shutdown events via cron. You also have the option to add custom ports to devices which will be pinged. In this step by step guide I will show you how to install UpSnap on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest UpSnap 5.0.5 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
