Basics
What this software actually is, whether it works, and whether it costs anything.
V2Ray is an open-source network proxy tool that builds an encrypted tunnel between your device and your destination site, helping you reliably access sites and services when your network environment is restricted. See "About V2Ray" for more.
Yes. V2Ray and its clients for every platform are free, open-source software. This site offers downloads and step-by-step guides for every platform at no cost — there's no "premium" or paid version.
You'll need a "subscription link" (basically a string of server config info), which is normally provided by your service provider. This site doesn't offer or sell subscription services — we just show you how to use the link once you have one.
The software itself is a neutral network tool — whether its use is compliant depends on the laws where you live. Please make sure you understand and follow your local rules before using it.
Download & Install
Download sources, choosing a client, and prompts you might see during installation.
v2rayN is the cross-platform client covering Windows, macOS, and Linux; v2rayNG and V2flyNG are both Android clients with the same core, just slightly different interfaces — pick either one for your device.
Yes, that's normal. Since this kind of software involves network proxying, some systems and antivirus tools flag installers that aren't signed at large scale. It's fine to choose "Install anyway/Trust" and continue.
This site only maintains a download link for the current latest version and doesn't offer older releases. That way beginners won't accidentally install an outdated version with known issues, and the version number shown always matches what you actually download.
Connecting & Using
Common situations after installation: connecting, subscriptions, and everyday use.
This is usually caused by an expired subscription node or misconfigured routing rules. Try updating your subscription or switching nodes first, then work through the troubleshooting guide if the issue continues.
Paste the link into the client's "Subscription settings" and save, then tap "Update subscription" to pull the node list. We recommend enabling auto-update so your node info doesn't go stale. See the subscription import guide for details.
Usually caused by a Chinese Android phone's power-saving policy clearing the background process. Follow the "Set up background keep-alive" steps in the Android guide and add the client to your battery optimization whitelist.
The client itself doesn't limit this — whether multiple devices can use the same subscription simultaneously depends on your subscription provider's rules. If you're unsure, check with them directly.
