Reclaimerr is an open-source application that automatically reclaims disk space in Jellyfin and Plex media libraries using customizable rules. Acting as the reverse of Seerr, it analyzes your media content to identify and clean up unwatched, old, or low-value items, helping maintain efficient storage and organization. In this step by step guide I will show you how to install Reclaimerr on your UGREEN NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Reclaimerr v0.1.0 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.
