**NetBird is an open-source VPN management platform built on top of WireGuard® making it easy to create secure private networks for your organization or home.**

It requires zero configuration effort leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.

NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, datacenter, container, cloud or edge environments) unifying virtual private network management experience.

**Key features:**
- \[x] Automatic IP allocation and network management with a Web UI ([separate repo](https://github.com/netbirdio/dashboard))
- \[x] Automatic WireGuard peer (machine) discovery and configuration.
- \[x] Encrypted peer-to-peer connections without a central VPN gateway.
- \[x] Connection relay fallback in case a peer-to-peer connection is not possible.
- \[x] Desktop client applications for Linux, MacOS, and Windows (systray).
- \[x] Multiuser support - sharing network between multiple users.
- \[x] SSO and MFA support. 
- \[x] Multicloud and hybrid-cloud support.
- \[x] Kernel WireGuard usage when possible.
- \[x] Access Controls - groups & rules.
- \[x] Remote SSH access without managing SSH keys.
- \[x] Network Routes.  

**Coming soon:**
-  \[ ] Private DNS.
-  \[ ] Mobile clients.
-  \[ ] Network Activity Monitoring.

**Note**: The `main` branch may be in an *unstable or even broken state* during development. 
For stable versions, see [releases](https://github.com/netbirdio/netbird/releases).

### Start using NetBird
-  Hosted version: [https://app.netbird.io/](https://app.netbird.io/).
-  See our documentation for [Quickstart Guide](https://netbird.io/docs/getting-started/quickstart).
-  If you are looking to self-host NetBird, check our [Self-Hosting Guide](https://netbird.io/docs/getting-started/self-hosting).
-  Step-by-step [Installation Guide](https://netbird.io/docs/getting-started/installation) for different platforms.
-  Web UI [repository](https://github.com/netbirdio/dashboard).
-  5 min [demo video](https://youtu.be/Tu9tPsUWaY0) on YouTube.


### A bit on NetBird internals
-  Every machine in the network runs [NetBird Agent (or Client)](client/) that manages WireGuard.
-  Every agent connects to [Management Service](management/) that holds network state, manages peer IPs, and distributes network updates to agents (peers).
-  NetBird agent uses WebRTC ICE implemented in [pion/ice library](https://github.com/pion/ice) to discover connection candidates when establishing a peer-to-peer connection between machines.
-  Connection candidates are discovered with a help of [STUN](https://en.wikipedia.org/wiki/STUN) servers.
-  Agents negotiate a connection through [Signal Service](signal/) passing p2p encrypted messages with candidates.
-  Sometimes the NAT traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT) and p2p connection isn't possible. When this occurs the system falls back to a relay server called [TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT), and a secure WireGuard tunnel is established via the TURN server. 
 
[Coturn](https://github.com/coturn/coturn) is the one that has been successfully used for STUN and TURN in NetBird setups.

### Testimonials
We use open-source technologies like [WireGuard®](https://www.wireguard.com/), [Pion ICE (WebRTC)](https://github.com/pion/ice), and [Coturn](https://github.com/coturn/coturn). We very much appreciate the work these guys are doing and we'd greatly appreciate if you could support them in any way (e.g. giving a star or a contribution).
