Our Analysis

Immich100.2k★

Immich is the self-hosted photo and video management platform that actually competes with the big players. Upload from your phone, browse on the web, search by faces, places, or objects using on-device ML. AGPL v3, TypeScript backend with a Flutter mobile app. Automatic backup from iOS/Android, facial recognition, reverse geocoding, timeline view, shared albums, and a map view. Machine learning runs locally on your server for object detection and face clustering. Self-hosting is free. Docker Compose is the recommended path; you need decent storage and ideally a GPU for faster ML, but CPU works too. Immich offers a paid license for businesses, but the software is fully functional without paying. Solo: perfect. Replace Google Photos for your personal library. Families: shared albums work great. Growing orgs: this isn't designed for enterprise photo management. Large: look at purpose-built DAM (digital asset management) solutions. The catch: Immich is pre-1.0 and the developers explicitly warn against using it as your only backup. The API and schema can change between updates. Keep your originals backed up elsewhere. ML features need real compute: 4GB RAM minimum, more for large libraries.

FFmpeg59.9k★

It's the command-line tool that powers nearly every media application you've used. YouTube, VLC, OBS, Discord, they all depend on FFmpeg. The entire project is free under LGPL/GPL (depending on which codecs you enable). No paid tier. No cloud service. No company selling premium features. This is one of the most important pieces of free software ever written, maintained by a relatively small team. There's nothing to host. It's a command-line tool you install on any machine. Every Linux distro packages it. macOS gets it via Homebrew. Windows has pre-built binaries. It runs, processes your media, and exits. Solo developers: you'll use it the moment you need to do anything with audio or video. Small teams: wrap it in a script for your media pipeline. Enterprise: you're already using it whether you know it or not. The catch: the command-line interface is notoriously complex. The man page is a novel. Simple things are simple (`ffmpeg -i input.mp4 output.avi`) but anything beyond basic conversion requires reading docs or StackOverflow. The learning curve is the only real barrier, and it's steep.

Remotion46.4k★

Remotion lets you write video content as React components and render them to MP4, perfect for data-driven animations and personalized video at scale. Instead of After Effects templates, you write JSX. The idea is wild and it works: your video is a React component, each frame is a render, and Remotion stitches them into video using FFmpeg. You can use any React library: charts, maps, 3D with Three.js, and it becomes video. The core Remotion player and composition tools are free. Rendering to video requires a license for companies with revenue above $100K/yr. Remotion Lambda (serverless rendering on AWS) is a separate paid product. Individual and small-revenue companies can use it free. The catch: rendering is slow and compute-heavy. A 60-second video can take minutes to render locally. Remotion Lambda speeds this up but adds AWS costs. The license model is unusual: it's free below a revenue threshold, then you pay. Check their pricing page carefully. And if you just need simple video editing (trim, concatenate, add text), FFmpeg with a wrapper is way simpler.

PhotoPrism39.6k★

PhotoPrism gives you automatic face recognition, location mapping, and AI-powered search across your photo library without sending your photos to anyone's cloud. Point it at a folder of images, and it indexes everything with object detection, color analysis, and GPS data. This is the most popular self-hosted photo management tool. It handles RAW files, videos, live photos, and generates thumbnails automatically. The search is good: type "beach" and it finds your beach photos without you tagging anything. The Community Edition is free. PhotoPrism Essentials ($3.99/mo) and PhotoPrism Plus ($7.99/mo) add features like enhanced video support, premium themes, and priority access to new features. The AI features (face recognition, search) are in the free tier. The catch: self-hosting PhotoPrism is not trivial. It needs Docker, a database (MariaDB recommended), and decent hardware for the AI indexing; a Raspberry Pi 4 works but initial indexing of a large library will take days. RAM usage is real: 4GB minimum, 8GB+ recommended for large libraries. And the license is AGPL-adjacent (custom); check terms carefully if you're building a product on top of it.
