Miniflux is a minimalist feed reader. It’s simple, fast, lightweight and very easy to use. Miniflux is compiled statically without external dependencies, drop the binary on your server and you are done. In this step by step guide I will show you how to install Miniflux on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Miniflux v2.2.6 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.
