NetBird
Open-source WireGuard-based mesh VPN that replaces traditional VPNs with Zero Trust, identity-based device access.

Description
A traditional company VPN works like a single door everyone has to walk through: all your traffic gets funneled to one central server, which gets slow and becomes a single point of failure. NetBird takes a different approach — it lets your devices talk directly to each other over an encrypted tunnel (using a fast, modern technology called WireGuard), and instead of a separate VPN password, you log in with the same account you already use for work (Google, Microsoft, Okta...). Once connected, an admin decides who can reach what, rather than trusting everyone equally after login.
Technically, NetBird is an open-source (BSD-3-Clause core, AGPLv3 management plane) Zero Trust Network Access platform: it builds a peer-to-peer WireGuard mesh between devices, layers identity-provider SSO/MFA on top, and applies access policies centrally through a management dashboard, API, and Terraform provider. It supports Linux, Windows, macOS, iOS, Android, Docker and routers, and can be self-hosted or used as a managed cloud service. With 28.9k GitHub stars it has real community traction, competing directly with Tailscale and legacy corporate VPN appliances.
💬 Our review
The short version: NetBird is a genuinely modern alternative to clunky corporate VPNs, and being open-source with a real free tier makes it low-risk to try — but adopting it means rethinking network access around identity rather than a single VPN password, which is a mindset shift for smaller teams.
Its closest comparison is Tailscale, which pioneered this WireGuard-mesh-plus-SSO model; NetBird's pitch is being open-source end to end (including the AGPLv3 management plane) and self-hostable, whereas Tailscale's control plane is closed-source SaaS. For teams that want to own their infrastructure or avoid per-seat SaaS lock-in, that matters; for teams that just want the simplest possible setup, Tailscale's polish still has an edge. Pricing is competitive (free up to 5 users/100 machines, then €6-12/user/month), but self-hosting the management server requires real DevOps comfort — worth it for security-conscious or budget-constrained teams, overkill if you just need three laptops to see a home server.
