v2rayN, v2rayNG, and v2flyNG Compared

v2rayN brings desktop subscription, server, and routing management together. Import a subscription, create groups, and update or organize configurations separately. When you need to change how traffic is handled, check your routing settings and system proxy status. If you use several subscriptions, naming groups first and selecting a configuration from the right group is clearer than searching through a long server list.

There are also more settings than a simple connect toggle. If you're new to the client, start with the basics: import a subscription, select a configuration, and enable the system proxy. Once everything works as expected, explore TUN, DNS, or switching cores. TUN availability depends on OS permissions and the client and core configuration; if you don't need to route more traffic, start with the system proxy. Choose an installer that matches your operating system and device architecture, and don't confuse the desktop release with the classic Windows WPF release.

v2rayNG is an Android client powered by the Xray core. A typical setup is to import a subscription link, update the configurations, select a server, and connect. Android will ask for VPN permission when connecting; this lets the client manage device traffic through the system interface. If you need per-app traffic handling, check the per-app proxy settings rather than changing every rule from the start.

With v2rayNG, first check that the current client and core can parse the configurations in your subscription. Matching protocol names don't guarantee compatibility: transport or security fields may differ. If importing succeeds but the connection doesn't work, check the subscription update, configuration fields, and logs before changing routing. Switching clients alone usually won't fix incorrect server-side parameters.

v2flyNG is also an Android client, but it uses the v2fly core. Its main use case isn't an older device or a simpler interface; choose it when your configuration specifically requires the v2fly core, or when you want to use protocols and features supported by that core family. Before importing a subscription, check the provider's protocol, transport, and security settings to confirm that the current core supports the required fields.

If both Android clients can read the same configuration, choose based on the settings you need. If it depends on a specific core feature, prioritize core compatibility. Users with older phones should also check installer architecture, Android version, and available storage rather than choosing based on the phone's age alone. Test one configuration after installation, then add other subscriptions and routing rules gradually.
