One small free app replaces six tools for running your home movie and music server

A new free app called HolyArrs wants to do the work of six apps that many people use to run a home movie, TV and music library. It is about a 15 MB download. The six apps it replaces total 718.2 MB. The project got 106 points and 54 comments on Hacker News, a popular tech discussion site.

What it does

A home media server is a computer that stores your shows, movies and music and streams them to your devices. Keeping it stocked usually takes several helper apps. HolyArrs folds them into one: Sonarr, Radarr, Lidarr, Bazarr, Prowlarr and Seerr. That means one login, one port and one place to check when a show does not arrive.

You browse like a streaming app and ask for a title. HolyArrs searches your sources, picks the best version using your rules, sends it to your downloader and files it in your library. Friends and family can make requests, and you approve them.

The numbers

• About 15 MB to download, versus 718.2 MB for the six apps, measured on 2026-11-08.
• About 140 MB of memory when idle with 10,000 titles in the library.
• Runs on amd64, arm64 and armv7 chips.
• Free, open source, under the AGPL-3.0 license.

Trying it safely

HolyArrs installs through Docker, a tool that runs apps in self-contained packages. The project gives a short setup file, and the app opens in a web browser on port 6262. To switch, you add each old app's address and key in Settings, run a Try it step, then choose Move. A move can be undone later.

HolyArrs only reads your old apps and changes nothing in them. Both can run side by side until you trust the new one. Media files never move.

What it does not do

• It does not replace your downloader, such as qBittorrent or SABnzbd. A built-in one is planned for later.
• Keys and passwords do not carry over. Custom formats, tags and history do not either.
• There are no phone or TV apps yet. The web app works on a phone.
• AI features are not in version 1.0, and music in Explore is still being built.

Who runs it

The project is run by one developer, who says the posters, trailers and scores come from a server paid for personally and kept free through sponsors. The latest release, 1.0.18, adds a Minimal look with small posters and fixes eight issues. The GitHub page shows 656 stars and 30 forks.
