How to Install Changedetection on Your Synology NAS

Changedetection is a self-hosted change monitoring of web pages. Know when web pages change! Stay on top of new information! Live your data-life pro-actively instead of re-actively, do not rely on manipulative social media for consuming important information. Know when Government department updates (changes are often only on their websites) – Local government news (changes are often only on their websites) – New software releases, security advisories when you’re not on their mailing list – Festivals with changes – Real-estate listing changes. In this step by step guide I will show you how to install Changedetection on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Changedetection 0.49.16 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.
