Happ — the recommended client for IT CRP.

Happ is a free, open-source proxy utility built on the Xray core. It imports your IT CRP VPN key with one tap, works on every device you own, and doesn't send your activity to external servers. We recommend Happ to every IT CRP customer because it's the cleanest path from "you have a VPN key on screen" to "connected".

Happ · the short version

Why we recommend Happ specifically

There are dozens of subscription-compatible Xray clients. We pick Happ because of the user-experience details, not just the technical compatibility.

Same Xray family as our servers

Our routes run on Xray-core with VLESS-Reality and XTLS-Vision. Happ is also built on Xray-core. That means subscription import is one tap (Happ understands the format natively) and every advanced feature we expose on the server side — Reality fingerprinting, Vision flow control, route auto-selection — works without any client-side configuration on your part.

No logging, confirmed by the developer

From happ.su: "Happ ensures your network activity remains private by not collecting any data; your information remains solely on your device without being sent to external servers." We don't have a way to verify that beyond reading the code, but for a free open-source client built on Xray that statement is consistent with how the protocol works — there's no telemetry endpoint baked in.

Works on platforms most VPN clients ignore

Happ ships native binaries for iOS, Android, macOS, Windows, Linux, Apple TV, and Android TV. If you have a Linux laptop, an Apple TV in your apartment in Shanghai, or an old Android tablet you keep around — Happ runs on all of them with the same subscription URL.

Free, no affiliate kickbacks

We don't pay Happ to recommend them. Happ doesn't pay us to be recommended. The recommendation is editorial — Happ happens to be the best Xray client we know of for the IT CRP customer profile. If a better one shows up, we'll update this page.

You can leave us without changing apps

Happ is a generic Xray client — it works with any VLESS or VMess subscription URL, not just IT CRP. If you ever leave us for a different provider, your Happ install keeps working with the new subscription. That's deliberate: we'd rather earn your renewal than lock you into our ecosystem.

Download Happ

Choose the device you are setting up right now. Store links are easiest when they work; direct GitHub builds are the backup path for China networks and devices without Google services.

China fallback

Inside China, use the APK first. If Google Play opens on your network, the Play Store install is also fine.

Download APK → Google Play
Testing build: Beta APK
Windows

Desktop installer

Use the official x64 installer from GitHub releases. Run setup, approve the VPN driver prompt, then import your IT CRP key.

How to use Happ with IT CRP · 30 seconds

From "I have my IT CRP VPN key on screen" to "connected" without any manual configuration.

STEP 01

Install Happ for your platform

Use one of the download links above. iOS install requires an international Apple ID if your phone is set to the China region; Android installs directly from APK if Google Play isn't reachable.

STEP 02

Get your IT CRP subscription URL

Sign up at it-crp.com/signup for the free 1 GB key. The VPN key appears on the next screen and stays available in your dashboard.

STEP 03

Tap the URL in the email

iOS and Android: tapping the link opens Happ and imports the profile in one tap. Mac and Windows: copy the URL, open Happ, choose "Add subscription" and paste it.

STEP 04

Tap connect, allow VPN, test your apps

Happ asks for permission to add a VPN configuration the first time. Allow it. Tap connect. The right route auto-selects. Your apps load again.

What you're actually trusting when you install Happ

  • Happ runs as a system VPN on your device. It can see all your network traffic before it's encrypted by IT CRP. The "no logging" claim from the developer is what stops that traffic from being sent anywhere — but it's a trust statement, not a cryptographic guarantee.
  • Built on Xray-core. Xray is open-source and widely audited; the protocols it implements (VLESS, Reality, XTLS-Vision) are publicly specified. The Happ wrapper around Xray is what's harder to audit independently.
  • App Store / Play Store distribution adds Apple's and Google's review layer. Direct GitHub APK / DMG / EXE binaries skip that layer — you trust the GitHub release directly. For most people, the store path is the right default.
  • If trust is a primary concern, alternatives exist. Shadowrocket (paid, iOS only), Clash Verge (open-source desktop), sing-box (CLI-first), v2rayN (Windows). All accept IT CRP subscription URLs. We recommend Happ for ease of use, not as the only option.

Happ questions

Is Happ open-source and free?
Happ is a free cross-platform proxy utility built on the open-source Xray core. The desktop and Android binaries are distributed via GitHub releases at github.com/Happ-proxy. The iOS and macOS apps are free in the App Store. There are no ads and no in-app purchases on the standard build.
Does Happ work in China?
Yes. Happ is just the client — what makes a connection work in China is the server profile and the obfuscation protocol. IT CRP gives you a VLESS-Reality + XTLS-Vision profile that defeats the Great Firewall's deep packet inspection, and Happ knows how to import and use that profile. The combination works inside mainland China including on hotel, university, and apartment Wi-Fi.
Can I use Happ with other VPNs or proxies?
Yes. Happ is a generic Xray client and works with any subscription URL or configuration that targets the VLESS, VMess, Trojan, Shadowsocks, or Socks protocols. You can have multiple subscription profiles in the same Happ install (IT CRP, a personal server, a friend's setup) and switch between them. Nothing about Happ ties you to IT CRP.
Why doesn't IT CRP have its own branded app?
Two reasons. First, Happ is already excellent and we'd rather not build a worse copy of it. Second, recommending an independent open-source client means you're not locked into our ecosystem — if you ever leave us, your subscription URL imports into the same Happ on the same phone with no migration. Less lock-in, more trust. We may build a branded client eventually for distribution reasons (App Store discovery), but it would still be a fork of Happ-class technology, not a closed black box.
What's the difference between Happ-Proxy-Utility and Happ-Proxy-Utility-Plus on the App Store?
The Plus variant is a Russia-specific App Store listing with the same core functionality, distributed under a separate developer account because of regional App Store policies. For users in China, Hong Kong, or anywhere else, use the standard Happ-Proxy-Utility from the global App Store. Both versions import IT CRP subscription URLs identically.
