* [client] Reuse the profile's account for iOS SSO logins Android reads the profile's stored account and passes it as the OIDC login_hint, and records it again after a successful login. iOS did neither: it called GetOAuthFlow with an empty hint, so a re-login was resolved by whatever session the browser's cookie jar held rather than by the account the profile belongs to. With a non-ephemeral browser session that is the wrong account as soon as more than one is signed in. Mirror client/android/login.go: hint from mobile.ReadProfileEmail before the flow, mobile.WriteProfileEmail after Login succeeds. Storing after Login and not before keeps a rejected token from leaving a hint that points at an account which cannot be used. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * [client] Persist the account email on tvOS and on the device flow Two paths left a profile with no account bound, so every later login went out without a login_hint — the case this change exists to remove. WriteProfileEmail went through util.WriteJsonWithRestrictedPermission, which writes a temp file and renames it over the target. The tvOS App Group sandbox blocks exactly that, which is why the config sitting next to this file is written with DirectWriteOutConfig. On tvOS the email write therefore failed and was dropped with a warning. Use DirectWriteJson: the file is rewritten whole from a single key, so the only thing atomicity buys here is surviving a crash mid-write, and a torn file reads back as "no email" and is replaced by the next login. The device authorization flow never populated TokenInfo.Email, unlike the PKCE flow, so a client driven through it — Android TV and tvOS — bound no account at all. Parse the ID token there too. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * [client] Report a failed close from DirectWriteJson The deferred close assigned its error to err, but the return value was not named, so the assignment went nowhere: a close that failed was logged and the function still returned nil. The write is only durable once the file closes cleanly, so every caller — the management config, the profile configs and the profile account email — could be told the data landed when it had not. Name the return so the assignment does what its shape always intended, and report the failure once. When the body succeeded the close error is returned and the caller logs it. When the body already failed, that error is the one that explains the failure and is what the caller gets, which leaves the deferred log as the only place the close failure can surface — at debug, per the logging rules for close errors on writes.

🤖 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.
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).
