NetBird ranks #7 in Developer Tunnels & Localhost Ingress AI search.

NetBird is an open-source Zero Trust Network Access (ZTNA) platform built on WireGuard® that enables organizations to create secure, private overlay networks without traditional VPN gateways or complex firewall configurations. Founded in 2021 in Berlin by Mikhail (Misha) Bragin and Maycon Santos, the platform uses a peer-to-peer mesh architecture with NAT traversal to establish encrypted tunnels directly between devices across any environment. NetBird supports both a cloud-hosted SaaS model and full self-hosting under BSD-3 and AGPLv3 open-source licenses. Core capabilities include identity-based access control, SSO and MFA with major identity providers, device posture checks via MDM and EDR integrations, centralized management, SIEM event streaming, and a Terraform provider for infrastructure-as-code. Backed by ~$15.4M in total funding from Pace Capital, Nauta Capital, InReach Ventures, and Antler, NetBird positions itself as a European-sovereign alternative to US-dominated VPN and ZTNA vendors.
