UmlautAdaptarrEX

Overview

UmlautAdaptarrEX - Umlaut and multi-language title proxy for Sonarr, Radarr, Lidarr, Readarr and Prowlarr. Complete Next.js + Fastify + Prisma rewrite of the legacy .NET UmlautAdaptarr. Sits between your *Arr stack and the indexers, rewrites searches and Newznab/Torznab responses on the fly so releases with umlauts, German titles, TVDB aliases or bad naming are reliably found, downloaded and imported. Ships a full Web UI with setup wizard, dashboard, sync runs, request and rename history, and live WebSocket logs. Configuration and title cache are stored in a persistent SQLite DB under /data - no external database required. Highlights: Sonarr / Radarr (native via alternateTitles + optional TMDB) / Lidarr / Readarr / Prowlarr / NZB Hydra support, multiple instances per *Arr type, language plugins (German umlauts, Swedish umlauts, French accents) that can be combined, configurable title providers (TVDB, TMDB, db-cache), optional release renaming, two operating modes (Prowlarr indexer proxy on 5006 or direct as indexer on 5005), German + English UI.
