* [client] Keep the route selection when every requested ID is unavailable
A non-append SelectRoutes() wipes the current selection before applying
the requested one, but it validated the requested IDs only afterwards,
while already mutating. A request naming no available route at all left
every route deselected and returned an error - so a typo in a route ID
silently dropped the user's exit node, and the routes stayed applied
while the selector claimed nothing was selected.
Validate first and bail out before touching any state when nothing in
the request is available. A request with at least one available route
keeps applying the valid part and reporting the rest, and an empty
request still deselects everything, since that is the caller asking for
exactly that rather than a failed lookup.
* [client] Trim the new comments to the contributing guide's length budget
CONTRIBUTING.md caps comments at 90 characters per line and roughly 250
per comment. The three comments added by this PR were over both limits.
The test comments also restated their own test names, so they lose that
half and keep only the why.
* [client] Apply the route selection even when some IDs are unknown
SelectRoutes and DeselectRoutes returned the error before TriggerSelection,
so a request mixing valid and unknown network IDs changed the selector but
never reached the routing table. The valid routes read as selected while
`ip route` showed nothing.
Trigger the selection first and return the error afterwards. The inner
selectRoutes already applied the valid part of a partial request, only the
outer layer dropped it.
* [client] Publish the network selection event on a partial failure
Returning early on error was correct while an error meant nothing had
happened. A partial failure now changes the selection and the routing
table, so returning first left the change with no trace in the event log
or the UI, even though the new state had already been broadcast.
* [client] Cover the append and deselect-all paths of the selection guard
The append path was never destructive and behaves the same with or without
the early return, so that case is characterization rather than a regression
test. The deselect-all case is a real guard: the early return also skips
resetting deselectAll, so a typo no longer drops the "nothing selected,
including future networks" policy.
* [client] Pin that a fully invalid selection disturbs nothing
The selection is now applied on every request, including one where no ID is
known and the selector is left untouched. Nothing may be torn down or
reinstalled on that path.
* Revert "[client] Publish the network selection event on a partial failure"
This reverts commit 26219592.
The event would lie on the opposite path: when no requested ID is available
the selector is left untouched, so an unconditional publish reports a change
that never happened. Telling that case from a partial failure needs the
manager to report whether anything was applied, which is a new signal in its
API and does not belong in a PR about the selector guard. Follow-up instead.

🤖 NetBird Agent Network (Beta)
Identity-aware access control for AI agents — keyless access to LLM APIs and private resources over the encrypted NetBird tunnel. See
agent-network/or read the docs at netbird.ai.
NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.
Connect. NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
Secure. NetBird enables secure remote access by applying granular access policies while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.

Self-host NetBird (video)
Key features
Quickstart with NetBird Cloud
- Download and install NetBird at https://app.netbird.io/install.
- Follow the steps to sign up with Google, Microsoft, GitHub or your email address.
- Check the NetBird admin UI.
Quickstart with self-hosted NetBird
This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM. Follow the Advanced guide with a custom identity provider for installations with different IdPs.
Infrastructure requirements:
- A Linux VM with at least 1 CPU and 2 GB of memory.
- The VM should be publicly accessible on TCP ports 80 and 443 and UDP port 3478.
- A public domain name pointing to the VM.
Software requirements:
- Docker with the Compose plugin (Compose v2 or higher). See the Docker installation guide.
Steps
- Download and run the installation script:
export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started.sh | bash
A bit on NetBird internals
- Every machine in the network runs the NetBird agent, which manages WireGuard.
- Every agent connects to the Management Service, which holds network state, manages peer IPs, and distributes updates to agents.
- Agents use ICE (via pion/ice) to discover connection candidates for peer-to-peer connections.
- Candidates are discovered with the help of STUN servers.
- Agents negotiate a connection through the Signal Service, exchanging end-to-end encrypted messages with candidates.
- When NAT traversal fails (e.g. mobile carrier-grade NAT) and a direct p2p connection isn't possible, the system falls back to a Relay Service and a secure WireGuard tunnel is established through it.
See a complete architecture overview for details.
Community projects
- NetBird installer script
- netbird-tui - terminal UI for managing NetBird peers, routes, and settings
- caddy-netbird - Caddy plugin that embeds a NetBird client for proxying HTTP and TCP/UDP traffic through NetBird networks
Note: The main branch may be in an unstable or even broken state during development.
For stable versions, see releases.
Support acknowledgement
In November 2022, NetBird joined the StartUpSecure program sponsored by the Federal Ministry of Education and Research of the Federal Republic of Germany. Together with the CISPA Helmholtz Center for Information Security, NetBird brings security best practices and simplicity to private networking.
