How to Install Kumiho on Your Synology NAS

Kumiho is a lightweight self-hosted web media server built in Go, created for efficiently organizing and streaming personal collections of comics, manga, webtoons, light novels, and other image-based content. It delivers high performance with very low resource usage, making it well-suited for running on modest hardware such as NAS devices or Raspberry Pi boards. The application automatically mirrors your existing folder structure without requiring any metadata entry or reorganization, providing a clean tree-view navigation that feels intuitive and immediate. Scanning libraries happens quickly thanks to its native compiled binary, and the responsive web interface works smoothly on desktops, tablets, and phones. A standout feature is the dedicated vertical scrolling mode optimized for long-strip webtoons, along with automatic background music playback that triggers matching MP3 files placed inside series folders for added immersion while reading. It currently supports common image files including JPG, JPEG, PNG, WebP, GIF, and BMP, as well as ZIP and CBZ archives that are handled as chapters or volumes. Support for more archive formats including .cbr, .rar, .cb7, .7z, .epub, .pdf, and .txt are planned soon. This makes Kumiho an excellent choice for anyone seeking a fast, privacy-focused, zero-hassle alternative to heavier comic servers like Kavita or Komga, particularly when preserving original file layouts and minimizing system overhead matters most. In this step by step guide I will show you how to install KumihoĀ on your Synology NAS using Docker and Portainer.

šŸ’”Note: This guide works perfectly with the latest Kumiho v0.7.4 release.
