NetBird is an open-source Zero Trust Networking platform designed by engineers, for engineers. It radically simplifies how modern organizations deploy and manage secure private networks offering the speed, security, and scalability todayโ€™s distributed teams demand.

Built on the trusted, high-performance WireGuardยฎ protocol, NetBird overcomes the traditional limitations of legacy VPNs by creating high-throughput, low-latency decentralized private networks. Its robust architecture provides a single, intuitive management console that enables granular, identity-based access control, integrating seamlessly with your existing Identity Provider (IdP) to support SSO and MFA out of the box.

With native IdP integration, your devices, servers, and cloud environments form direct, encrypted tunnels to each other - no central gateway or bottleneck. The centralized control plane offers full visibility, policy enforcement, and point-and-click management for secure remote access across hybrid and multi-cloud setups.

NetBirdโ€™s decentralized architecture delivers multiple key advantages:

Zero bottlenecks: Traffic flows directly between peers, avoiding latency and bandwidth constraints from central gateways.

Enhanced resilience: With no single point of failure, users stay connected even if on-prem infrastructure fails. Cloud-to-cloud and user-to-cloud links remain fully operational.

Scalability and privacy: Lightweight clients on each peer manage encrypted communication, while the management plane handles authentication and policy distribution without ever seeing your data.

Seamless integrations: Works effortlessly with CrowdStrike, Microsoft Intune, SentinelOne, pfSense, OPNsense, and more. MSPs can manage multiple customer environments securely from a unified dashboard.

Use NetBird for secure remote access, zero-config VPN replacement, Zero Trust enforcement, dynamic posture checks, centralized management, detailed logging and many more features.

  • How I Ditched Datadog and Built a Self-Hosted Monitoring Stack on a $5 VPS
    NetBird creates a WireGuard mesh between your machines. The key feature is Network Routing โ€” one peer acts as a gateway for a whole subnet. So your monitoring stack lives on 172.19.0.0/16, and any connected peer can reach Grafana at http://172.19.0.3:3000 without exposing anything to the internet. - Source: dev.to / 3 months ago

    > Also, sometimes it seems like I get rate limited on Tailscale. As I understand it if everything is working properly you should end up with a peer to peer wireguard connection after initial connection using tailscales infrastructure. ie, there should be nothing to rate limit. There are exceptions depending on your network environment where you need one of the relays noted in this post. As for opensource... - Source: Hacker News / 6 months ago
