Automatic Ripping Machine (ARM) is a production-grade application that automates the ripping of optical discs (Blu-ray, DVD, CD) using MakeMKV, HandBrake, abcde, and FFmpeg. It is triggered by udev rules on disc insertion, identifies the disc type and metadata via OMDb/TMDB/MusicBrainz, rips the content, optionally transcodes, and moves files to a configured output directory. The system runs as a Flask web application with a SQLite database, providing a web UI for job management, settings, logs, and notifications via Apprise. It supports multiple drives, parallel ripping, and hardware transcoding (Intel QSV, AMD VCE, NVIDIA NVENC). The architecture is a monolith with a Flask backend and a separate ripper process invoked by udev. The codebase is well-structured with Flask blueprints, SQLAlchemy models, Alembic migrations, and a JSON API for AJAX interactions. Key modules include the ripper orchestrator (arm/ripper/main.py), disc identifier (arm/ripper/identify.py), MakeMKV/HandBrake wrappers, and a comprehensive settings UI. The project is Docker-first but also provides a Debian installer and systemd service. Strengths include a mature feature set, active maintenance, and a large community. Weaknesses include hardcoded paths, a hardcoded Flask secret key, permissive CORS, some shell=True usage, and duplicate utility functions across modules. Test coverage is sparse but present for core ripper components. The codebase is functional and well-documented but has some technical debt that would benefit from refactoring.
Overseerr is a full-stack self-hosted web application for managing media requests in a Plex ecosystem. Users can search for movies and TV shows via TMDB, submit requests (including 4K variants), and have those requests automatically pushed to Radarr/Sonarr for download. The application also tracks media availability by scanning Plex libraries, syncs Plex watchlists, and provides a comprehensive notification subsystem supporting Discord, Telegram, Slack, email, webhooks, and web push. It includes user management with granular permissions, quota enforcement, issue reporting, and a highly customizable discovery page built from TMDB-driven sliders, genres, networks, and studios. The frontend is Next.js (React) with Tailwind CSS, SWR, Formik, and react-intl i18n; the backend is Express with TypeORM on SQLite. The project is feature-rich and has been widely adopted, but the README states it is superseded by the Seerr community fork, and the codebase relies on several aging dependencies (Next.js 12, React 18, Tailwind 3) and a hardcoded TMDB API key. Despite this, the code is well-organized with clear separation between API clients, entities, routes, and UI components, and many parts are written with solid engineering patterns such as a base external API client with caching/rate limiting, a template-method scanner base class, and a clean notification agent interface.
