Sign in to your XDA account Summary Holyarrs combines Sonarr/Radarr/Lidarr-like features into a single Spotify-like web app. It's only a 15MB download and uses just 70MB RAM with 12,800 titles indexed. Built via Claude vibe-coding with strict size/speed limits. If you're really into running your own home server, you probably use a wide range of apps, including Sonarr, Radarr, Lidarr, bazarr, Prowlarr and Seerr, just to name a few. Each of these apps has its own UI and operating sytem, and in most cases, takes up somewhere between 110-140mb. In short, things can get complicated very quickly. That's why Reddit user CoderLuii used Claude to build Holyarrs, an app they say "does all of it and feels like Netflix." Best of all, it's only 15mb to download and uses just 70mb of RAM with 12,800 movies and TV shows in it. When they vibe-coded the project, CoderLuii says that they placed strict limits on how much memory Holyarrs can use, how quickly it boots up, and how big the overall app can be. They also performed extensive testing, including asking Claude to build the Plex-like app in two different ways. One version was "3x lighter" and much faster, so they went with that option. Instead of its own operating system, Holyarrs is just one simple web app that aims to replicate the functionality of apps like Sonarr, Radarr, and Lidarr. The app's UI looks very similar to Spotify in a lot of ways, which is apparently intentional given its overall look was inspired by the music streaming platform. Holyarrs developer has big plans for the app The response from users so far has been very positive Credit: Holyarrs Unlike a lot of similar vibe-coded projects, you can find Holyarrs full roadmap at this link (Holyarrs website is also pretty cool looking). It's a pretty interesting read where CoderLuii unpacks exactly how they pulled the project together. The early response to the app in the r/ClaudeAI Reddit thread where CoderLuii first revealed the project is overall pretty positive. Holyarrs isn't open-source yet, but it will be eventually. I haven't tried Holyarrs myself yet, so I can't personally say whether it's worth checking out or not. That said, as far as vibe-coded media server projects go, it looks pretty impressive. More importantly, it seems like its developer is taking the app very seriously (XDA will have more on Holyarrs soon). In terms of other interesting AI-related stories, someone recently used Claude to create a sailing simulation, and then challenged other LLMs to a race.
