FreshRSS is a free, self-hosted RSS and Atom feed aggregator for following websites, podcasts, and video channels. Users can read and search articles, save searches, and organize items with custom tags. Feed management includes OPML import and export, creating feeds from filters, and scraping websites to make feeds. WebSub provides real-time updates from compatible feeds. The project says the software can manage 1M+ articles and 50k+ feeds. FreshRSS supports multiple users, anonymous reading, themes, extensions, configurable options, and a command-line interface. APIs support mobile clients, and Google Reader and Fever APIs enable use with mobile and native clients. Self-hosting requires a web server, PHP 8.1 or later, and PostgreSQL 10+, SQLite, MariaDB 10.6+, or MySQL 8.0+. The project advises exposing only the ./p/ folder to the web because ./data/ contains personal data. It offers no warranty and welcomes bug reports and feature requests through GitHub issues.
