TUN and traffic capture
Supports TUN-based traffic capture, depending on the build, components, permissions, and system environment.
Uses Android VpnService to create a virtual interface; setup differs from a desktop TUN toggle.
Also requires Android VPN permission; check the specific build for traffic capture options.
App-level controls
System proxy covers only apps that honor the setting; use TUN and routing to consider broader coverage.
Per-app proxy lets you include or exclude selected apps from traffic capture.
Configure app filters using the options provided by the client, and check what each list means.
Best for
Everyday desktop use, subscription organization, rule editing, and troubleshooting across multiple windows.
Everyday Android use, especially for users who need Xray features or per-app controls.
Android users with existing V2Fly configs who are willing to check compatibility limits.
A closer look at the three clients
The client determines how you manage configurations; the core determines how connections are handled. Choosing the right fit at both levels makes migration and troubleshooting more straightforward.
v2rayN: Desktop Subscription and Routing Management
Top desktop pick
v2rayN’s main advantage is the flexibility of its desktop interface. Subscription groups, server settings, routing rules, and runtime logs can be viewed separately, which helps when you need to check configurations in detail. Windows users should distinguish the cross-platform desktop edition from the classic WPF edition when downloading. The former follows the cross-platform interface direction, while the latter retains familiar Windows workflows. Menus and components may differ, so don’t assume a button in a guide will be in the same place in both editions.
Start with the system proxy for basic use. Consider TUN only if you need to capture traffic from apps that ignore the system proxy. Before enabling it, check the required components and permissions; afterward, verify that DNS and routing behave as expected. TUN broadens the range of traffic captured; it does not improve the server route or replace routing rules. Switching cores is not a performance shortcut either. If an existing configuration relies on core-specific fields, check compatibility first.
Key settings: Subscription groups / Routing / DNS / Core type
v2rayNG is a good fit for Android users who need Xray configuration support. After importing a subscription, don’t look for a desktop-style toggle with the same name. Grant VPN permission, select a configuration, then choose which apps to include in traffic capture. Android VpnService provides the virtual network interface; the core still uses routing rules to decide whether captured traffic is proxied, sent directly, or blocked. A VPN icon in the status bar only confirms that the service is running—it doesn’t mean every destination is reachable.
Per-app proxy is a useful mobile control, but make sure you understand whether the list includes or excludes apps. If an app isn’t included in traffic capture, changing domain rules in the core usually won’t affect its connection path. Long-running connections can also be affected by system battery policies. If the connection drops when the screen locks, check background restrictions and battery optimization before switching clients. It’s also worth checking how the client reconnects when switching between mobile data and Wi-Fi on your device.

v2flyNG: An Alternative for the V2Fly Configuration Ecosystem
Android alternative
The main reason to choose v2flyNG is its V2Fly core, not its similar name to v2rayNG. It’s a more targeted option if your existing configurations are built for V2Fly or you need to reproduce behavior with that core. Subscription imports and connections follow familiar Android client workflows, but check the current build for supported link formats, extension parameters, and advanced settings.
When migrating from v2rayNG, don’t just compare server addresses. Check the transport type, security layer, domain-related parameters, and routing fields. In particular, don’t assume Xray-specific features are supported by both clients. Using V2Fly doesn’t automatically mean better battery life or better performance on older devices, either. Evaluate maintenance, system compatibility, and the protocols you use separately. If you don’t have a specific need for V2Fly, v2rayNG is the easier starting point for Android users following this site’s guides.
First check whether traffic reaches the client, then see how the core routes it. Traffic capture and routing are separate issues.
Desktop: System proxy depends on app support
When you set a system proxy, apps that honor the setting send requests to a local listening port. Some apps have their own proxy settings or connect directly, so a working browser and failing apps don’t immediately point to a server problem. First check whether the target app uses the system proxy, then check the local port and listener status. This makes troubleshooting more systematic.
Desktop: TUN captures more traffic
TUN uses a virtual network interface to handle traffic from more apps, but also requires coordination between routing, permissions, and DNS. Other virtual adapters or proxy services can cause interface and routing conflicts. Don’t enable multiple traffic capture services just to compare clients. Start with one capture method, verify the basic connection, then add rules one at a time. Packages for the same platform may still have different runtime requirements.
Android: Separate permissions, app filters, and core routing
Android clients use VpnService to capture traffic. Per-app settings decide which apps enter that path, and core routing determines the outbound route for captured traffic. In most everyday setups, VPN services running in the same user space compete with one another, so stop the current service before testing another client. This comparison is about traffic capture mechanisms, not whether the remote server uses a particular VPN protocol.
Choose a client by use case
A few clear requirements can narrow the options more effectively than a long feature list.
What to check before downloading
In short: v2rayN is the top desktop pick, v2rayNG the top Android pick, and v2flyNG is for specific V2Fly requirements.
Check the platform and architecture. Choose a package for your desktop operating system. On macOS, distinguish Apple Silicon from Intel; on Linux, check both package format and processor architecture. For Android, choose an arm64 or universal package based on your device.
Check the configuration source and core requirements. A single share link and a subscription URL are updated differently. A working subscription doesn’t mean every configuration in it is compatible with the selected core, so check key parameters after importing.
Check which traffic needs to be captured. If you only need a browser, start with the desktop system proxy. Consider TUN if you need to cover more apps. On Android, decide whether to enable per-app filtering first, so you don’t mistake a traffic capture issue for a routing issue.
Test under the same conditions. Keep the network, server configuration, destination, and test method consistent, and run only one traffic capture service at a time. Connection latency and download speed measure different things; short-term results don’t predict long-term stability.
This page doesn’t rank clients by speed without accounting for the device and network route. Client logs can help identify whether a failure occurs during parsing, handshake, or forwarding. If the connection drops in the background, check system permissions and battery settings.
