Image size isn’t a good proxy for features here. Sonarr/Radarr/Lidarr/Prowlarr are .NET, Bazarr is Python, Overseerr is Node. Each Docker image ships its own runtime and base OS layer, so a big chunk of those ~718 MB is the same kind of overhead duplicated six times. One static Go binary skips all of that. And the *arrs in my opinion really should not be different tools, each has its own indexer handling, download client integration, queue, scheduler, database, auth and web UI. Most of what each tool does completely overlaps with the others. So even more of the overhead is not necessary.
