Explore the core features and technology behind Youyou Accelerator
Youyou Accelerator fully adopts the WireGuard protocol, which contains just 4,000 lines of code—only 1/100th of IPsec’s codebase—yet provides 3-5 times faster transmission speeds. This streamlined code results in a smaller attack surface and enhanced security, allowing you to enjoy ultra-fast speeds without worrying about privacy breaches.
Youyou Accelerator enforces the industry's strictest zero-logs policy — not recording your connection time, visited websites, IP addresses, or any browsing data. This policy has been independently audited by the internationally renowned security firm Cure53, with a complete report published to ensure that every claim is verifiable.
Youyou Accelerator's smart routing engine continuously monitors the latency and load on global nodes, automatically selecting the optimal route for you. One-click connection can result in latencies as low as 15ms, providing a smooth experience for video conferencing, online gaming, or 4K streaming without interruptions.
Youyou Accelerator has deployed over 3000 high-speed servers in more than 80 countries and regions, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, wiping all data upon restart, effectively eliminating the possibility of data retention at the hardware level.
Using a single Youyou Accelerator account, you can simultaneously secure your phone, computer, tablet, smart TV, and router - up to 6 devices connected at once, allowing your entire family to share a secure network without additional fees. After configuring your router, you can even protect IoT devices that don’t support accelerators.
Youyou Accelerator boasts a professional bilingual customer support team available 24/7. Whether you need help with installation, connection issues, or account management, you can receive instant, expert assistance via online chat or email, with an average response time of under 2 minutes.
Learn how the cutting-edge routing protocols utilized by Youyou Accelerator provide you with ultimate speed and security.
Youyou Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves complete accelerator functionality with just about 4,000 lines of code, while traditional IPsec requires over 600,000 lines. This streamlined coding approach causes a smaller attack surface, lower latency, and higher throughput. In our internal testing, the handshake speed of the WireGuard protocol is three times faster than IKEv2 and eight times faster than IPsec.
Youyou Accelerator's implementation of WireGuard employs the Noise protocol framework for key exchange, using Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been extensively validated by both academia and industry, providing prospective security against quantum computing attacks.
In certain network environments, UDP traffic from WireGuard may be restricted. Youyou Accelerator features an intelligent protocol switching function that can automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our proprietary obfuscation protocol to ensure stable connections in any environment. The entire switching process completes within 500 milliseconds, making it hardly noticeable to users.
Multi-layer encryption technology and strict privacy policies to fully protect your digital life.
Youyou Accelerator employs the AES-256-GCM encryption mode for all transmitted data. AES-256 is the encryption standard currently approved by the NSA for protecting 'top secret' level information. Even using the most powerful supercomputers for brute force attacks would take billions of years to break. Each connection generates a unique session key, ensuring forward secrecy.
Youyou Accelerator operates its own private DNS server cluster, with all DNS queries encrypted and resolved through a secure connection, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring your real IP address is never exposed under any circumstances. You can verify your protection status at any time with the built-in leak testing tools.
Youyou Accelerator's Kill Switch feature can immediately cut off all internet traffic if the acceleration connection drops unexpectedly, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode protects only selected applications, giving users maximum flexibility.
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy exciting global content.
Youyou Accelerator's high-speed nodes are specifically optimized to reliably support the transmission demands of 4K Ultra HD (2160p) video streams. Whether it's high-definition movies, live sports events, or music videos, Youyou Accelerator provides a stable, smooth, and buffer-free viewing experience. With gigabit broadband, connection speeds can consistently exceed 500Mbps.
Youyou Accelerator is specially optimized for online gaming. Our smart routing engine automatically selects the route with the lowest latency to the game server. In our tests, latency connecting to Asia-Pacific game servers is as low as 10ms, with North American servers seeing latencies as low as 60ms. DDoS protection helps prevent malicious attacks during gaming.
Youyou Accelerator has enabled P2P optimization features on nodes in over 30 countries worldwide. We impose no bandwidth or speed limits on P2P protocols like BitTorrent, while protecting your download activities from ISP monitoring and throttling through encrypted connections. Port forwarding features improve torrenting efficiency, supporting faster upload speeds.
