Features
Next-Gen WireGuard Protocol
Onion Accelerator fully employs the WireGuard protocol, using only 1/100th of the codebase of IPsec while delivering 3-5 times the transmission speed. The streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy exceptional speed without worrying about privacy breaches.
Audited No-Logs Policy
Onion Accelerator implements the industry's strictest no-logs policy—never recording your connection times, websites visited, IP addresses, or any browsing data. This policy has been independently audited by the internationally recognized security firm Cure53, with a full report published, ensuring that every commitment stands up to scrutiny.
Milliseconds Smart Connection
Onion Accelerator's smart routing engine continuously checks the latency and load of nodes worldwide, automatically matching you with the best route. One-click connections achieve latency as low as 15ms, providing a smooth, uninterrupted experience whether for video conferencing, online gaming, or 4K streaming.
Nodes Covering Over 80 Countries
Onion 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, erasing all data upon reboot to prevent any possibility of data retention at the hardware level.
One Account, 6 Devices Online Simultaneously
With a single Onion Accelerator account, you can simultaneously protect 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 costs. After configuring your router, even non-accelerator-supported IoT devices can be protected.
24/7 Professional Customer Support
Onion Accelerator has a bilingual professional customer support team available 24/7. Whether you need help with installation, connection issues, or account management, you can receive immediate and expert assistance via online chat or email, with an average response time of under 2 minutes.
WireGuard Core Architecture
Onion Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves complete accelerator functionality with about 4000 lines of code, while traditional IPsec requires over 600,000 lines. The more concise code means a smaller attack surface, lower latency, and higher throughput. In our internal tests, WireGuard's handshake speed is 3 times faster than IKEv2 and 8 times faster than IPsec.
Noise Protocol Framework Encryption
Onion Accelerator's WireGuard implementation utilizes 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 widely validated in academia and industry, providing a forward-looking security guarantee against quantum computing attacks.
Smart Protocol Switching
In certain network environments, UDP traffic from WireGuard may be restricted. Onion Accelerator has a built-in smart protocol switching feature 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 almost imperceptible to users.
Multi-Hop and split routing
Onion Accelerator supports multi-hop connections, relaying data through two or more acceleration servers, providing an additional layer of privacy for users who require extreme anonymity. Meanwhile, the split routing feature allows you to choose which applications use the accelerator and which connect directly to the local network, optimizing both performance and security.
AES-256-GCM Encryption Standard
Onion Accelerator uses AES-256-GCM encryption mode to encrypt all transmitted data. AES-256 is currently the encryption standard approved by the US National Security Agency (NSA) for protecting classified 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
Onion Accelerator operates 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, ensuring that your real IP address is never exposed under any circumstances. You can verify your protection status through our built-in leak testing tools at any time.
Kill Switch
Onion Accelerator's kill switch feature can immediately cut off all internet traffic if the acceleration connection drops unexpectedly, preventing any data from being leaked in an unencrypted state. This feature supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode only protects specific applications, providing users with maximum flexibility.
RAM-Only Pure Memory Servers
All of Onion Accelerator's over 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 reboot, all data is completely wiped out. Even if servers are physically seized, no user data can be extracted. This represents the highest standard of data protection in the industry.
4K Ultra HD Streaming Support
Onion Accelerator's high-speed nodes are specially optimized to support the demands of transmitting 4K ultra HD (2160p) video streams reliably. Whether it's HD movies, live sports events, or music videos, Onion Accelerator can provide a steady, smooth, buffer-free viewing experience. On gigabit broadband, connection speeds can consistently maintain over 500Mbps.
Gaming Acceleration and Low Latency
Onion Accelerator has specifically optimized connections for online gaming. Our smart routing engine can automatically select the route with the lowest latency to game servers. In our tests, latency to Asia-Pacific game servers is as low as 10ms, and to North American servers, as low as 60ms. DDoS protection features prevent you from suffering malicious attacks during gameplay.
P2P and Torrent Download Optimization
Onion Accelerator has enabled P2P optimization on nodes in over 30 countries worldwide. We do not impose bandwidth or speed limits on peer-to-peer protocols like BitTorrent, while ensuring your download activities are shielded from ISP monitoring and throttling through encrypted connections. Port forwarding capabilities enhance seeding efficiency and support faster upload speeds.
Smart Content Acceleration Technology
Onion Accelerator's proprietary SmartRoute technology intelligently recognizes the type of content you are accessing and automatically selects the optimal transmission path. It switches to streaming-optimized nodes when watching videos, large bandwidth nodes when downloading files, and prioritizes low-latency nodes when browsing the web. The entire process is fully automated, requiring no manual intervention.
