Explore the core features and technology behind Clash Accelerator
Next-Gen WireGuard Protocol
Clash Accelerator fully utilizes the WireGuard protocol, with only a fraction of the code size of IPsec, yet delivering 3-5 times the transmission speed. The streamlined code means a smaller attack surface and enhanced security, enabling you to enjoy incredible speed without worrying about privacy leaks.
Audited No-Logs Policy
Clash Accelerator implements the industry's strictest no-logs policy—no logging of connection times, websites visited, IP addresses, or browsing data. This policy has been independently audited by the internationally recognized security firm Cure53, with a full report available, ensuring each commitment stands up to scrutiny.
Millisecond-Level Intelligent Connection
Clash Accelerator's intelligent routing engine detects delays and loads of global nodes in real-time, automatically matching you to the optimal route. With one-click connection and latency as low as 15ms, whether for video conferencing, online gaming, or 4K streaming, you can expect a smooth, uninterrupted experience.
Coverage in Over 80 Countries
Clash Accelerator operates over 3,000 high-speed servers in more than 80 countries across North America, Europe, Asia-Pacific, South America, and the Middle East. Each server runs in pure RAM mode, erasing all data upon reboot, eliminating the possibility of data retention at the hardware level.
One Account, 6 Devices Online Simultaneously
Using one Clash Accelerator account, you can protect your phone, computer, tablet, smart TV, and router simultaneously—up to 6 devices can connect at once, allowing your entire family to share a secure network without additional costs. Once configured on a router, it can even protect IoT devices that do not support accelerator.
24/7 Professional Customer Support
Clash Accelerator has a bilingual professional support team available around the clock, offering assistance in both English and Chinese. Whether you have questions about installation, connection issues, or account management, you can receive immediate and professional help via live chat or email, with an average response time of less than 2 minutes.

Core Architecture of WireGuard
Clash Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard implements full accelerator functionality with only about 4,000 lines of code, while traditional IPsec requires over 600,000 lines. The streamlined code results in a smaller attack surface, lower latency, and higher throughput. In our internal tests, WireGuard's handshake speed is three times faster than IKEv2 and eight times faster than IPsec.
Encryption via Noise Protocol Framework
Clash 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 extensively validated in both academia and industry, offering prospective security against quantum computing attacks.
Smart Protocol Switching
In certain network environments, WireGuard's UDP traffic may be restricted. Clash Accelerator features built-in smart protocol switching that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring stable connections in any environment. The entire switching process occurs within 500 milliseconds, almost imperceptibly to users.
Multi-Hop and split routing
Clash Accelerator supports multi-hop connections, allowing data to relay through two or more acceleration servers, providing an additional layer of privacy for users seeking extreme anonymity. Meanwhile, the split routing feature lets you select which applications use the accelerator and which connect directly to the local network, achieving the best balance of performance and security.
Encryption and Privacy Protection
Multi-layer encryption technologies and stringent privacy policies provide comprehensive protection for your digital life
AES-256-GCM Encryption Standard
Clash Accelerator employs the AES-256-GCM encryption mode for all transmitted data. AES-256 is currently the encryption standard endorsed by the NSA for protecting 'top secret' information. Even with the most powerful supercomputers available today, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Clash Accelerator operates its own private DNS server cluster, ensuring all DNS queries are resolved through the encrypted connection, thus eliminating the risk of DNS leaks. We also provide WebRTC and IPv6 leak protection, ensuring your real IP address is never exposed. You can verify your protection status at any time using the built-in leak testing tool.
Kill Switch
Clash Accelerator's network lock feature (Kill Switch) instantly cuts off all internet traffic when the acceleration connection unexpectedly drops, preventing any data from leaking unencrypted. This feature supports both system-wide and application-specific modes: the system-level mode protects all traffic, while the application-level mode protects only designated applications, offering maximum flexibility to users.
RAM-Only Pure Memory Servers
All of Clash Accelerator's 3,000+ servers operate in pure RAM mode. This means there are no hard drives on the servers, and all data is handled solely in memory. Upon each server restart, all data is completely erased. 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 allow you to enjoy global content
4K Ultra HD Streaming Support
Clash Accelerator's high-speed nodes are specially optimized to consistently support the transmission demands of 4K ultra-high-definition (2160p) video streams. Whether it's HD movies, live sports events, or music videos, Clash Accelerator provides a stable, smooth, and buffer-free viewing experience. Under gigabit broadband, connection speeds can reliably maintain above 500Mbps.
Gaming Acceleration and Low Latency
Clash Accelerator has been specifically optimized for online gaming. Our intelligent routing engine can automatically select the route with the lowest latency to gaming servers. In our tests, the latency when connecting to Asia-Pacific gaming servers is as low as 10ms, with North American servers at about 60ms. The DDoS protection feature prevents you from falling victim to malicious attacks during gaming.
P2P and Torrent Download Optimization
Clash Accelerator has enabled P2P optimization on nodes in over 30 countries. We do not impose bandwidth or speed limits on P2P protocols like BitTorrent while ensuring your download activities are protected from ISP surveillance and throttling through encrypted connections. The port forwarding capability enhances seeding efficiency, supporting faster upload speeds.
Smart Content Acceleration Technology
Clash Accelerator's proprietary SmartRoute technology intelligently identifies the type of content you're accessing and automatically selects the most optimized transmission path. The system switches to streaming-optimized nodes while watching videos, to high-bandwidth nodes for file downloads, and prioritizes low-latency nodes for web browsing. The entire process is fully automated, requiring no manual intervention.
