Open Source PowerShell User Interface (UI) Software

Posterizarr is a creative automation tool designed for media server enthusiasts who want to generate attractive posters for their media libraries on platforms like Plex, Jellyfin, or Emby. It’s implemented as a PowerShell-based application with a comprehensive web UI that makes it easy to configure and trigger image generation tasks. Posterizarr fetches artwork from sources such as Fanart.tv, TMDB, TVDB, IMDb, and applies customizable overlays and design rules to produce clean, textless posters tailored to your library’s preferences. It supports integration with tools like Tautulli, Sonarr, and Radarr so that poster generation can be triggered automatically based on media library updates or other events. With platform support across Linux, Windows, and ARM devices, along with Docker and typical hosting environments, it’s used by many home media administrators to keep their poster collections consistent, visually pleasing, and up to date.
