V2Ray Client Comparison
Platform, Core, and Setup Differences

On Windows, macOS, or Linux, start with v2rayN. Its GUI brings subscription groups, configuration lists, system proxy, and routing settings together. Get a basic connection working first, then add rules as needed. You can keep multiple subscription sources in separate groups; before updating, check the selected group so new subscriptions don't get mixed in with older configurations.

Desktop setups have two separate layers: the system proxy determines which apps send requests to the client, while routing rules determine how those requests are handled. “Auto-configure system proxy” works for browsers and other apps that use the system proxy, but it won't capture traffic from every app. If an app ignores the system proxy, consider TUN mode rather than changing every setting at once.

v2rayN can use either the Xray or V2Fly core, but that doesn't mean both support exactly the same protocol parameters. If an existing configuration depends on a specific Xray feature, keep the matching core. TUN traffic handling is separate from the proxy protocol core; troubleshoot permission or virtual network adapter issues for your platform instead of assuming a core switch will fix them.

The Windows download page offers a desktop edition and a classic WPF edition. The former uses a newer cross-platform interface; the latter retains the classic workflow. On macOS, choose a package for your chip. On Linux, select a package for your distribution and processor architecture. Packages with similar names are not interchangeable.

For most Android users, v2rayNG is the place to start. The basic workflow is straightforward: add a subscription, update the configuration, select one to use, start the service, and grant Android VPN permission. It uses the Xray core, making it a clear choice for configurations that rely on Xray-specific protocol features. For example, if a configuration uses REALITY, check current Xray support rather than trying to run it directly on the V2Fly core.

Traffic handling on a phone differs from desktop. Android's VPN service creates a local entry point for traffic. A VPN icon in the status bar only confirms that this system-level route is active; it doesn't prove the remote connection is working. After importing a configuration, test by opening the site you want to reach. If it fails, check the subscription, selected configuration, logs, and network environment in that order.

For app-specific routing, look for per-app proxy settings; for domain- or address-based routing, check the routing rules. These settings apply to different things, so change one at a time. Android battery restrictions are another common factor: if the connection drops when the screen turns off and returns when you reopen the app, check background permissions before reinstalling the client.

Check your device's architecture before downloading. Most newer devices use the arm64 package. If you're unsure or installation reports an incompatibility, check the universal build and system requirements. The universal build covers more architectures; it doesn't lower the app's Android version requirements.

The main reason to choose v2flyNG is its V2Fly core—not an assumption that an alternative app uses fewer resources. If your existing configuration depends on V2Fly behavior, or you need to reproduce an issue within the same core family, consider it as an Android alternative. For new users without that specific need, v2rayNG is the better starting point, and its instructions are easier to follow consistently.

The two Android clients have a similar basic workflow: import a valid configuration and grant Android VPN permission. That doesn't mean their settings are interchangeable. The core in use must support the protocols, transport methods, and extra fields in your subscription. Being able to import a link doesn't guarantee that its configuration will start or connect successfully.

Consider maintenance separately from feature compatibility. v2flyNG is community-maintained, so check its release cadence and core compatibility independently; don't assume it follows v2rayNG's update schedule. Before migrating, keep the old client and a working configuration. Test basic access, per-app routing, and background operation under the same network conditions, then clean up old data once everything works.

Don't judge performance on older devices by the core name alone. System compatibility, available memory, background restrictions, protocol, and network route all affect the experience. Comparisons are meaningful only when test conditions are documented. If installation fails, check the Android version and device architecture before repeatedly switching clients.
