what is free fr?

freefq/free is a repository that publishes a regularly updated list of free proxy server configuration strings for use with v2ray, Shadowsocks, and Trojan, which are network proxy protocols commonly used to route internet traffic through servers in other countries. The description and README are written in Chinese and focus on providing access to content that is blocked by China's Great Firewall, the national internet filtering system. The README contains a list of encoded connection strings pointing to proxy servers located in various countries, along with links to client applications for Android and Windows that can read these strings and connect through the listed servers. The repository has no listed primary programming language and contains no source code. It functions purely as a data distribution channel, updating the list of available proxy endpoints periodically. The project notes that all nodes are scraped from public sources on the internet and asks that they not be used for illegal purposes. You would use this repository if you needed free, publicly available proxy configurations for v2ray or Shadowsocks clients. The tech stack is not applicable as there is no source code, the content is plain text encoded proxy configurations distributed through GitHub.
