Explore the core features and technology behind 91 Accelerator
91 Accelerator fully adopts the WireGuard protocol, with a codebase just 1/100th the size of IPsec, yet delivering 3-5 times the transmission speed. The streamlined code means a smaller attack surface and higher security, allowing you to enjoy extreme speeds without worrying about privacy breaches.
91 Accelerator implements one of the industry's strictest no-logs policies — we do not record your connection times, websites visited, IP addresses, or any browsing data. This policy has been independently audited by the internationally recognized security organization Cure53, with a complete report available, ensuring that every commitment can withstand scrutiny.
91 Accelerator's intelligent routing engine monitors latency and load across global nodes in real time, automatically matching you with the best route. With just one click, latency can be as low as 15ms, ensuring a smooth, glitch-free experience for video calls, online gaming, or 4K streaming.
91 Accelerator has deployed over 3000 high-speed servers across 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, meaning all data is cleared upon reboot, eliminating the possibility of data retention at the hardware level.
A single 91 Accelerator account protects your phone, computer, tablet, smart TV, and router — supporting up to 6 devices simultaneously, allowing the whole family to share a secure network without any extra fees. Once configured on a router, it can even protect non-accelerator capable IoT devices.
91 Accelerator has a bilingual customer support team available 24/7, providing round-the-clock assistance. Whether it's installation, connection issues, or account management, you can get instant, professional help through live chat or email, with an average response time of under 2 minutes.
Discover how the cutting-edge routing protocol used by 91 Accelerator provides you with unmatched speed and security
91 Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves full accelerator functionality with only about 4000 lines of code, compared to over 600,000 lines for traditional IPsec. The streamlined code leads to a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol is three times faster than IKEv2 and eight times faster than IPsec.
91 Accelerator's implementation of WireGuard uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been widely validated in academia and industry, providing forward-looking security against quantum computing attacks.
In some network environments, WireGuard's UDP traffic may be restricted. 91 Accelerator has a built-in intelligent protocol switching feature that can automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our self-developed obfuscation protocol, ensuring stable connections in any environment. The entire switching process occurs within 500 milliseconds, making it nearly imperceptible to users.
Multi-layer encryption technology combined with a strict privacy policy, fully protecting your digital life
91 Accelerator employs AES-256-GCM encryption mode for all transmitted data. AES-256 is the encryption standard approved by the NSA for protecting 'top secret' information. Even with the strongest supercomputers available today, it would take billions of years to crack. A unique session key is generated for each connection to ensure forward secrecy.
91 Accelerator runs its own private DNS server cluster, ensuring all DNS queries are resolved through encrypted connections, eliminating the risk of DNS leaks. We also have built-in WebRTC leak protection and IPv6 leak protection to ensure 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.
91 Accelerator's Kill Switch feature can instantly cut off all internet traffic if the acceleration connection unexpectedly drops, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: the system-level mode protects all traffic, while application-level mode only safeguards specified applications, giving users maximum flexibility.
High-speed connections specially optimized for streaming and online entertainment, allowing you to enjoy global content
91 Accelerator's high-speed nodes are specifically optimized to reliably support the transmission requirements for 4K ultra HD (2160p) video streams. Whether it's HD movies, live sports events, or music videos, 91 Accelerator ensures a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently exceed 500Mbps.
91 Accelerator is specially optimized for online gaming. Our intelligent routing engine automatically selects the lowest latency routes to gaming servers. In our tests, latency to Asia-Pacific gaming servers has been as low as 10ms, and as low as 60ms to North American servers. DDoS protection prevents malicious attacks during gaming sessions.
91 Accelerator enables P2P optimization features on nodes in over 30 countries. We do not limit bandwidth or speeds for P2P protocols like BitTorrent, while also protecting your download activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency, supporting faster upload speeds.
