V2Ray Client Comparison
Choosing a Platform and Core
For desktop, start with v2rayN; for Android, start with v2rayNG. Consider v2flyNG only if your setup specifically depends on the v2fly core.
Start with your device, check your node parameters, then choose how to manage subscriptions, routing, and traffic. Similar client names don't mean their features or configurations are interchangeable.
Compare Features Across Three Clients
This table compares everyday use, not which client has the most features. Menus, protocol support, and permissions depend on the client and core build you install.
| Comparison | v2rayN | v2rayNG | v2flyNG |
|---|---|---|---|
| Platforms | Windows、macOS、Linux | Android | Android |
| Core | Typically uses Xray; TUN support depends on the selected core and build | Xray core; protocol support varies with core updates | v2fly core; check protocol and configuration support against V2Fly |
| Maintenance | Actively maintained; check for changes to the interface and core settings when updating | Actively maintained; check for system compatibility and core changes when updating | Maintained along the v2fly development path; review recent updates and system compatibility before choosing it |
| Ease of use | Basic tasks are straightforward; routing, DNS, and TUN settings take additional know-how | Importing subscriptions and connecting are straightforward; Android VPN permission is required | Similar to common mobile app workflows; check core compatibility first |
| Subscription management | Organize multiple subscription sources and server lists in one desktop interface | Manage subscriptions, update them, and switch servers on your phone | Manage subscriptions; confirm the source provides supported protocols and parameters |
| Routing controls | Room to manage desktop rules, review them, and change their order | Configure split tunneling with routing settings and custom rules | Manage split tunneling through routing settings; syntax and behavior follow v2fly |
| TUN and traffic handling | Includes TUN settings; availability depends on the platform, core, and permissions | Handles traffic through Android's VPN interface; desktop TUN instructions don't apply | Handles traffic through Android's VPN interface, within the scope of the client's settings |
| Best for | Desktop use, managing multiple subscriptions, troubleshooting routes, and advanced configuration | Everyday Android use and setups that need Xray protocol support | Android users with existing configurations or specific requirements for the v2fly core |
v2rayN: Desktop Subscription and Routing Management
For Windows, macOS, and Linux. Set up your subscription and system proxy first, then add split tunneling or TUN as needed.
Why choose it: Centralized settings make repeated adjustments easier
v2rayN shines as a desktop management tool. When you have multiple subscription sources, group them by source, then update subscriptions, filter servers, and switch connections. Troubleshooting is easier when you can review logs, routing settings, and system proxy status together. If you regularly compare settings and organize rules, that workspace is more useful than a simple connect button.
The Windows download page offers a desktop edition and a classic WPF edition. The desktop edition uses a newer cross-platform interface; the classic WPF edition suits users who prefer the original window layout. They don't use different proxy protocols, and neither is inherently faster. For macOS, identify whether your Mac has Apple silicon or an Intel processor. On Linux, check your CPU architecture and package format; don't follow Windows installation steps.
Know the difference: system proxy vs. TUN
Start by using the system proxy to test your connection. Only apps that honor system proxy settings will use them, so an app that ignores the proxy doesn't necessarily mean the server is down. If you need to route traffic from more apps, check the system permissions, core support, and DNS settings required for TUN. TUN isn't a speed boost; a misconfiguration can make the problem worse.
Start routing with a few rules you can verify. After each change, test the same destination and check the logs for the matching rule. Changing routing, DNS, the core, and the server all at once makes it hard to identify the cause. For help understanding the settings, read routing and split tunneling terminology before changing your configuration.
v2rayNG: Android Client with the Xray Core
For everyday mobile connections, subscription updates, and server switching. Check this option first if you need Xray-specific features.
Why choose it: Designed around everyday phone use
v2rayNG uses the Xray core. The usual workflow is to import a subscription, update the server list, select a server, and connect. When Android asks for VPN permission, it's setting up the traffic-routing connection; it doesn't mean the client provides a server. You'll still need a valid subscription or server configuration, with the protocol, address, port, and transport security parameters in place.
If your subscription includes REALITY parameters, confirm that fields such as the server name and public key were imported correctly according to the provider's instructions. If you can't connect, check the server settings and logs; seeing a server name in the app doesn't prove the configuration is complete. Xray support also changes with core updates, so older app builds may not recognize newer parameters. Keep a working copy of your configuration before updating.
Know the difference: Android background restrictions
Your Android connection depends on more than the client. Battery optimization, background activity limits, and other apps using the VPN connection can all cause disconnections when the app is in the background. If it works in the foreground but fails after the screen locks, check the app's battery and background permissions before checking your server. Reinstalling repeatedly won't replace targeted troubleshooting.
Routing rules determine how traffic is handled; app selection determines which apps are included. Understand both. Test with the default app scope, then change one setting at a time. Android VPN traffic handling differs from desktop TUN in its controls, permissions, and system behavior. Don't apply desktop instructions for administrator access or virtual network adapters to your phone.
v2flyNG: Choose It for v2fly Configurations
Consider it only if your existing configuration specifically depends on V2Fly; it's not a general-purpose replacement for v2rayNG.
Why choose it: Stay with the core your setup already uses
v2flyNG uses the v2fly core. If your existing setup, documentation, or configuration specifically targets V2Fly, and the features you need are available in the current build, choosing it can reduce the learning curve of switching cores. Importing subscriptions and connecting are straightforward; the key is to check protocol support and configuration fields, not whether the menus look familiar.
Project V provides useful background on this ecosystem; V2Fly and Xray are separate core development paths. Their shared origins don't mean their later extensions are identical. A subscription listing VMess or VLESS doesn't guarantee that every server will work in both mobile clients. Transport, security settings, and extension fields also affect compatibility.
Know the difference: an alternative isn't necessarily better for older devices
v2flyNG is an alternative core, not a special edition for older phones. Check the processor architecture, Android version requirements, and memory usage for the build you plan to use. v2flyNG isn't automatically more memory-efficient. Review recent maintenance notes, compatibility with your target system, and core changes; a familiar name or one successful connection doesn't guarantee long-term compatibility.
If your current v2rayNG setup connects reliably and you don't specifically need a v2fly feature, there's no need to switch just because another client's name looks similar. If you do test it, keep the original client and configuration, and test the same destination in each app. Avoid running two clients at once, since they may compete for Android's VPN connection. Redact subscription URLs and personal connection details before sharing logs or screenshots.
Choose by Use Case
Start with what you need to do, then decide whether you need extra configuration. You don't have to use the same client on every device.
What to Check Before Downloading
First, check the platform and architecture. Use v2rayN on desktop and choose the right package for Windows, macOS, or Linux. On Android, start with v2rayNG; choose v2flyNG only if you specifically need the v2fly core. The wrong architecture can prevent installation or startup; that doesn't necessarily mean there's a problem with your server.
Next, check the subscription protocols and core support. Confirm which protocols and transports your subscription actually provides, then make sure the client imports them correctly. A subscription URL is a source of configuration, not a public resource bundled with the client. If the URL is expired, access is restricted, or the response isn't in the expected format, troubleshoot the subscription source.
Finally, decide which traffic to route. The desktop system proxy, desktop TUN, and Android VPN interface are different controls. First decide whether you need to route browser traffic, a particular app, or more of your device's traffic, then configure permissions and routing accordingly. After the client reports a successful connection, test the destination and check the logs.
The recommendation is straightforward: use v2rayN on desktop, v2rayNG on Android, and consider v2flyNG only when you need its core. Visit the client downloads page to choose the right package, then follow the setup guide to import and test your configuration. If the client is installed but won't connect, use Troubleshooting to identify the issue instead of repeatedly switching clients.
