Everything listed here is something I personally use and only recommend after trying it. Signing up through my links doesn’t cost you extra—I get a small commission that helps offset my hosting costs.
VPS / Servers
DMIT ⭐ Top Recommendation
Hong Kong nodes with ultra-low latency (20-40ms), CN2 GIA backbone, native IPs, and strong streaming service support. Supports Hysteria2. I’ve been using it for over a year and it’s the most stable VPS provider I’ve tried.
- Hong Kong node: 20-40ms (from Guangzhou)
- US Los Angeles: CN2 GIA, 150-180ms
- Supported protocols: Xray VLESS + Hysteria2
Tencent Cloud International
Japan node as a backup option, competitively priced with frequent promotions. IP blocks are more common than DMIT, so it works well as a secondary choice.
