A free VPN subscription link service that automatically collects and updates proxy nodes for clash, v2ray, trojan, shadowsocks, and shadowsocksR protocols every 12 hours. The project provides subscription URLs hosted on GitHub and jsDelivr CDN for reliable access, supporting both Android and Windows clients. It is aimed at users seeking free tools for circumventing network restrictions. The repository warns that links are sourced from the public internet and should only be used for learning purposes, urging compliance with local laws. It also links to guides for configuring popular client applications and includes recommendations for affordable paid VPN services as alternatives.
