* [client] Surface session deadline rejections via SystemEvent and add timer arm debug logs When sessionwatch.Watcher.Update rejects a deadline (pre-epoch, too far in the future, or past the clock-skew tolerance) it silently zeroes the status recorder, leaving the UI with no "expires in" row and no indication of why. Publish a SystemEvent_ERROR on the AUTHENTICATION channel so the rejection appears in the UI event feed and the user knows re-login may be required. Also add Debugf log lines in armTimerLocked so that warning and final-warning timer fire-times are visible in logs without having to add instrumentation after the fact. https://claude.ai/code/session_01Y3bQoNgcVjTD4zDTvv7a8u * [client] Remove verbose arm-timer debug logs from sessionwatch The per-arm Debugf lines added noise on every deadline update. Rejection logging already happens at the call site in engine_authsession.go; the watcher itself needs no extra instrumentation. https://claude.ai/code/session_01Y3bQoNgcVjTD4zDTvv7a8u * [client] Leave userMessage empty on deadline-rejected event; use metadata key Daemon-layer PublishEvent userMessage strings are not localized — the UI reads metadata keys and builds its own locale-aware copy (same pattern as the session-warning events in event.go). Drop the hardcoded English sentence from the deadline-rejected event and instead surface the rejection reason via a new MetaSessionDeadlineRejected metadata key so the UI can detect and localize it. https://claude.ai/code/session_01Y3bQoNgcVjTD4zDTvv7a8u * [client] Revert silent deadline-rejected event; restore userMessage MetaSessionDeadlineRejected had no UI consumer: the tray only does metadata-driven localisation for MetaSessionWarning events; all other SystemEvents display userMessage directly (tray_events.go). Leaving userMessage empty made the rejection invisible to the user. Restore the English userMessage so the generic event path shows something, and remove the unused MetaSessionDeadlineRejected constant. https://claude.ai/code/session_01Y3bQoNgcVjTD4zDTvv7a8u * [client] Localize session deadline rejected notification via metadata key Follow the same pattern as session-warning events: the daemon emits an empty userMessage and puts the signal in a typed metadata key (MetaSessionDeadlineRejected); the UI tray detects the key and builds a locale-aware OS notification from i18n strings. Changes: - sessionwatch/event.go: add MetaSessionDeadlineRejected constant - engine_authsession.go: empty userMessage, use the new metadata key - ui/authsession/warning.go: re-export MetaDeadlineRejected for UI consumers - ui/tray_events.go: gate on isDeadlineRejected alongside isSessionWarning; new branch calls t.notify with localized title/body - i18n locales (en/de/hu): add notify.sessionDeadlineRejected.{title,body} https://claude.ai/code/session_01Y3bQoNgcVjTD4zDTvv7a8u --------- Co-authored-by: Claude <noreply@anthropic.com>

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.
Acknowledgements
We build on open-source technologies like WireGuard®, Pion ICE, and Rosenpass. We greatly appreciate the work these projects are doing, and we'd love it if you could support them too (e.g., by starring or contributing).
