Free Alternative to Tailscale

ZeroTier One is the original software-defined networking platform that predates Tailscale and remains a formidable free alternative for creating secure virtual networks across the internet. As a mature, battle-tested solution with over a decade of development, ZeroTier creates encrypted peer-to-peer connections between devices using a proprietary protocol that achieves similar outcomes to Tailscale's WireGuard approach. I recently deployed ZeroTier across a mixed environment of Macs, Linux servers, and IoT devices, and the setup process was remarkably straightforward. You create a virtual network, receive a 16-digit network ID, and join devices by running a single command. The free tier supports up to 25 devices per network and unlimited networks, which comfortably covers most small teams and serious homelab setups. Where ZeroTier truly shines is its flexibility. Unlike Tailscale's user-centric model, ZeroTier operates on a network-centric architecture, making it ideal for connecting infrastructure where user identities matter less than device connectivity. Performance on Apple Silicon Macs is excellent, with native builds available through Homebrew. The web-based management interface provides network rules, access controls, and flow rules for advanced traffic engineering. However, ZeroTier is not open-source at its core, and the company has adjusted free tier limits over the years, creating some uncertainty about future pricing. For users seeking a proven, zero-configuration VPN alternative that works everywhere Tailscale does, ZeroTier remains an excellent choice that sidesteps the per-user pricing model entirely.

Pangolin is an emerging open-source alternative that takes a fundamentally different approach from both Tailscale and ZeroTier, focusing specifically on identity-aware application access rather than full mesh networking. Built on WireGuard like Tailscale but completely open-source under the FOSSorial organization, Pangolin provides zero-trust remote access to specific applications and infrastructure without requiring full network tunneling. I tested Pangolin extensively for remote access to internal web applications, SSH servers, and database endpoints, and the experience was refreshingly focused. Instead of joining a virtual network, users authenticate through existing identity providers like Google, Azure AD, or OIDC, then gain access only to resources explicitly assigned to them. This application-centric model is particularly compelling for businesses and teams that want to avoid the security implications of full network access while maintaining granular control. The self-hosted option is completely free and runs on any server capable of running Docker. Pangolin supports macOS natively with a polished client application, and the GitHub repository shows active development with over 19,000 stars as of 2026. For homelab enthusiasts, the ability to self-host without any license concerns is a significant advantage over Tailscale's managed infrastructure. However, Pangolin's narrower focus means it excels at application access but may not replace Tailscale for users who need full network-layer mesh connectivity between all devices. The documentation is improving but less comprehensive than Tailscale's, and being a newer project, it carries some maturity risks despite the active community.
