Clash Plus
Top pickA good starting point for your first setup. After installation, import a subscription on the Config page, make sure it’s enabled, then choose a rule mode on the Proxy page. The system proxy only affects apps that follow system proxy settings. Look into TUN if you need coverage for more apps; avoid changing too many network settings during initial setup.
Quit other clients that are controlling the system proxy before use. Keeping your original subscription URL is safer than migrating the entire old data directory. See clashplus.io for product details.
