Features
Explore the core features and technology behind Free VPN for China
Next-Generation WireGuard Protocol
Free VPN for China fully adopts the WireGuard protocol, which has only 1/100th the code of OpenVPN but can deliver 3-5 times the transmission speed. The streamlined code means a smaller attack surface and higher security, allowing you to enjoy exceptional speed without worrying about privacy breaches.
Audited No-Logs Policy
Free VPN for China enforces the strictest no-logs policy in the industry—no recording of your connection times, visited websites, IP addresses, or any browsing data. This policy has been independently audited by the internationally recognized security firm Cure53, with a complete report ensuring that every promise stands up to scrutiny.
Intelligent Millisecond Connectivity
Free VPN for China's intelligent routing engine continuously monitors the latency and load of global nodes, automatically matching you to the best connection. With just one click, latency can be as low as 15ms, providing a smooth experience for video conferencing, online gaming, and 4K streaming.
Coverage in Over 80 Countries
Free VPN for China has deployed over 3000 high-speed servers across more than 80 countries, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, ensuring that all data is erased upon restart, eliminating the possibility of data retention from the hardware level.
One Account, 6 Devices Online Simultaneously
With a single Free VPN for China account, you can simultaneously protect your phone, computer, tablet, smart TV, and router—allowing up to 6 devices to connect at once, so your whole family can share a secure internet connection without any extra fees. After configuring your router, you can even protect IoT devices that don’t support VPNs.
24/7 Professional Customer Support
Free VPN for China has a bilingual professional customer support team available 24/7. Whether you need help with installation, connectivity issues, or account management, you can get instant, expert assistance via online chat or email, with an average response time of less than 2 minutes.
In-Depth Analysis of Protocol Technology
Learn how the cutting-edge tunneling protocols employed by Free VPN for China deliver exceptional speed and security
WireGuard Core Architecture
Free VPN for China has built a new tunneling engine based on the WireGuard protocol. WireGuard achieves full VPN functionality with only about 4000 lines of code, while traditional OpenVPN requires over 600,000 lines. This streamlined code translates to a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol was 3 times faster than IKEv2 and 8 times faster than OpenVPN.
Noise Protocol Framework Encryption
Free VPN for China's implementation of WireGuard uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been thoroughly validated by academia and industry, providing forward-looking security against quantum computing attacks.
Smart Protocol Switching
In some network environments, WireGuard's UDP traffic may be restricted. Free VPN for China includes a smart protocol switching feature that can automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our own obfuscation protocol, ensuring a stable connection in any environment. The entire switching process occurs within 500 milliseconds, virtually undetectable by users.
Multi-Hop and Split Tunneling
Free VPN for China supports multi-hop connections, allowing data to be relayed through two or more VPN servers for an additional layer of privacy for users requiring extreme anonymity. Additionally, the split tunneling feature allows you to choose which applications connect via the VPN and which connect directly to the local network, achieving the best balance between performance and security.
Encryption and Privacy Protection
Multi-layer encryption technology and strict privacy policies to comprehensively protect your digital life
AES-256-GCM Encryption Standard
Free VPN for China employs the AES-256-GCM encryption mode to secure all transmitted data. AES-256 is currently the encryption standard approved by the NSA for protecting ‘top secret’ information. Even the most powerful supercomputers would require billions of years to crack it through brute force. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Free VPN for China operates its own private DNS server cluster, ensuring all DNS queries are resolved through encrypted tunnels, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, guaranteeing that your real IP address is never exposed under any circumstances. You can verify your protection status at any time using the built-in leak testing tool.
Kill Switch
Free VPN for China's Kill Switch feature cuts off all internet traffic immediately if the VPN connection drops unexpectedly, preventing any data from leaking unencrypted. This feature supports both system-level and application-level modes: system-level protects all traffic, while application-level solely protects designated applications, providing maximum flexibility to users.
RAM-Only Pure Memory Servers
Free VPN for China's 3000+ servers operate in pure RAM mode. This means there are no hard drives on the servers, and all data is processed solely in memory. Upon each server restart, all data is completely wiped. Even if a server is physically seized, no user data can be extracted. This represents the highest level of data protection standards in the industry.
Streaming and Entertainment Optimization
High-speed connections optimized for streaming and online entertainment, letting you enjoy global content
4K Ultra HD Streaming Support
Free VPN for China's high-speed nodes are specially optimized to reliably support the transmission requirements for 4K Ultra HD (2160p) video streams. Whether it's high-definition movies, live sports events, or music videos, Free VPN for China guarantees a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently exceed 500Mbps.
Gaming Acceleration and Low Latency
Free VPN for China has been specifically optimized for online gaming. Our intelligent routing engine can automatically select the lowest-latency routes to gaming servers. In our tests, latency to Asia-Pacific gaming servers was as low as 10ms, while connections to North American servers reached as low as 60ms. Our DDoS protection feature prevents you from suffering malicious attacks while gaming.
P2P and Torrent Download Optimization
Free VPN for China has enabled P2P optimization across nodes in over 30 countries. We do not limit the bandwidth or speed of P2P protocols like BitTorrent, while protecting your downloading activities from ISP monitoring and throttling via an encrypted tunnel. The port forwarding feature enhances seeding efficiency, supporting faster upload speeds.
Smart Content Acceleration Technology
Free VPN for China's proprietary SmartRoute technology intelligently identifies the type of content you're accessing and automatically selects the most optimized transmission path. It switches to streaming-optimized nodes when watching videos, to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes for web browsing. The entire process is fully automated, requiring no manual intervention.
