About SingLinkVPN

• Security concerns

  The arrival of the AI era has accelerated the risks to network security and of privacy leaks. Against this backdrop, SingLinkVPN set out to give the community and internet users a tool for network security and personal privacy protection, reducing security incidents and personal privacy leaks, all through a simple one-tap connection.

• Real-world needs

  The SingLinkVPN community often runs into problems in everyday situations. For example, many community members travel frequently between countries while keeping up their own internet development work, but sometimes cannot use their usual network for work in another region, and a VPN solves exactly this problem. So one of SingLinkVPN's original aims is to respond to an accelerating, globalized world by making working styles more flexible and helping users keep up their daily work conveniently, anytime.

One-tap protection for everyday internet use: keep your connection private, reach your usual work tools while travelling between regions, and use the same account on all your devices.

• Free Plan

  High-speed free nodes in 10 countries, provided at random by the system; 200 MB a day on mobile and 500 MB a day on desktop, on unlimited devices, with no card required; plus Telegram notification proxy (iOS) and Auto SingLink.

• Proxy chaining

  Route traffic through an extra exit of your own, such as a SOCKS5 server, for a stable IP. Plus and above.

• Domain proxy rules

  Choose which domains use the VPN and which connect directly. Plus and above.

• Notification proxy

  Receive Telegram message notifications through the VPN on iOS.

• Ad blocking

  Block ads and known malicious sites at the network level. Plus and above.

• Every platform

  Apps for iOS, Android, Windows, macOS, Linux and TV, with one account.

Unlike ordinary VPN teams, SingLinkVPN is not run for profit; the team has chosen a different path. All income and resources are continuously invested in security research and maintenance costs, and in rewards for community contributors. Our research and development results are also reviewed regularly and then open-sourced, so the community can grow and improve them together.

SingLinkVPN develops its own protocol family. Each protocol is published with a public explainer, and the technical whitepaper is open to read.

• SingLink Beta

  Speed-first protocol and the only one on every plan, including the Free Plan, with a speed ceiling up to 1 Gbps on higher plans.

• SingLink Sola

  Next-generation transport rebuilt on the SingLink 2.0 stack, faster than Beta on speed, latency and packet loss. Plus and above.

• SingLink Mini

  A disguise layer on top of Beta, Sola or SingLink 2.0, built for instant video start and very low latency. Plus and above.

• SingLink 2.0

  High-stability protocol for difficult networks, with connection stability of up to 99%. Pro, Max and Rich.

Our security claims are backed by public reports you can check yourself.

• Third-party security audit

  VPNTestor's cross-platform security audit (report v1.0, 2026-07-27) scored SingLinkVPN 100/100. The full report, a Markdown copy and its SHA-256 checksum are public.

• No-logs verification

  A read-only review of the production environment (reference date 2026-07-29) found no persistent logs of visited sites, domains, DNS queries, source IPs or connections.

• SingLink Shield

  SingLink Shield blocks malicious sites and abuse at the network level in real time, without recording user activity.

Research results are reviewed regularly and then opened to the community, so others can check, reuse and improve them.

• Phase one is public

  Architecture notes, security and privacy models, reproducible performance methods, data formats and research tools are published on GitHub.

• First-generation protocol and client

  The SingLink protocol has evolved from SingLinkVPN's early versions to today's SingLink 2.0. The first-generation SingLink Beta and SingLinkVPN client carry forward its account-based permissions, device binding and security by design, and were released under Apache-2.0 after a security audit. The official apps and protocol have moved to a new-generation architecture that is not yet fully public for security reasons; the open-source plan continues.

• Responsible disclosure

  The repository includes a security policy for reporting vulnerabilities privately.

• SingChat

  Our customer-service and chat platform has open-sourced its MCP integration under the MIT licence.

The SingLinkVPN team aims to help users be safer, protect their privacy and make their internet use more convenient and flexible, but only for lawful purposes. SingLinkVPN does not support illegal use, and users must not break local laws. SingLinkVPN is also not to be used in countries or regions where VPNs are not supported. Once detected, any illegal activity will be blocked from using the service, and SingLinkVPN has also adopted the SingLink Shield security system as its own protective measure against such use. SingLink Shield blocks malicious sites and abuse at the network level in real time, without recording user activity.
