Mylar3

Mylar3 is the actively maintained Python 3 fork of Mylar — a long-running open-source comic book downloader and library manager. It plays the same role for comics that Sonarr does for TV shows or Radarr does for movies: watch a list of series, find new issues at indexers, queue them with your existing download client, and post-process the resulting files into a clean library that a reader app like Komga or Kavita can serve. The UI handles series tracking, story-arc management, ComicVine metadata enrichment, indexer configuration, download-client wiring, renaming rules, and a background scheduler that keeps everything moving without manual intervention.

Common Use Cases

Comic readers building a personal digital library use Mylar3 as the backbone of an "arr stack" for comics — adding ongoing series, story arcs, and back-issues to a watch list and letting Mylar3 keep them up to date as new issues are released. Self-hosters who already run a comic reader like Komga or Kavita pair it with Mylar3 so the reader's library always has fresh content without manual downloads, mirroring the Plex + Sonarr/Radarr workflow that many homelab users already operate. Hobbyist archivists track favorite publishers or runs that are otherwise hard to keep current, using ComicVine integration to ensure cover art, issue numbering, and metadata stay consistent across the collection. Power users with multiple download clients route different content types through dedicated paths — for instance NZBGet for newer issues and a torrent client for back-fill — and let Mylar3 dispatch each download to the right place. Multi-user households share a single Mylar3 instance behind reverse-proxy auth so several people can request series without each running a separate downloader.

Why deploy Mylar3 on Hostinger VPS

Running Mylar3 on a Hostinger VPS gives you a permanent, always-on automation engine for a personal comic library that does not depend on a desktop machine being awake or a residential connection that gets paused for ISP throttling. Dedicated CPU and disk on a VPS keep the background scheduler responsive even when many series fire updates at once, and persistent volume storage keeps the configuration database, the in-progress downloads, and the curated library safe across container restarts and host upgrades. Combined with Traefik-based HTTPS routing on a clean branded hostname, the Mylar3 web UI is reachable from any device while staying TLS-encrypted end-to-end. Self-hosting also keeps indexer credentials, download-client API keys, and your reading habits inside infrastructure you control, instead of streaming them to a SaaS request manager. For users already running download clients and a reader on the same VPS, Mylar3 ties everything together into a coherent automated pipeline.
