Community FAQ
Questions by product
Headscale FAQ
How complex is it to self-host Headscale compared to using the official Tailscale service?
Self-hosting Headscale requires moderate to advanced infrastructure knowledge, including managing a Linux server, setting up persistent storage for state, and configuring DNS and firewall rules. Unlike the official Tailscale service, you must handle updates, backups, and scaling yourself. While Headscale automates coordination for WireGuard meshes, it does not provide a managed UI or support, so operational overhead is higher.
Community insight informed by Reddit discussions
Does Headscale support offline or air-gapped environments where clients cannot reach an external coordination server?
Yes, Headscale is designed for self-hosted use and can operate entirely within an offline or air-gapped network as long as clients can reach the Headscale server. Since it implements the Tailscale coordination protocol locally, no external internet connectivity is required for client coordination or key distribution once the server is set up.
Community insight informed by Hacker News discussions
How does Headscale ensure data ownership and privacy compared to using Tailscale's cloud service?
Headscale stores all coordination metadata, authentication keys, and device information on your own infrastructure, giving you full control over data ownership and privacy. Unlike Tailscale's cloud service, no user or device data is sent to third-party servers, eliminating reliance on external trust boundaries and reducing exposure to data leaks or surveillance.
Community insight informed by Reddit discussions
Are there any API limitations or missing features in Headscale compared to the official Tailscale coordination server?
Headscale implements the core Tailscale coordination protocol but lacks some advanced features present in the official service, such as Magic DNS integration, ACL policy management UI, and certain device authorization workflows. The API surface is sufficient for basic client coordination, but some newer Tailscale features may not be supported or require manual configuration.
Community insight informed by StackOverflow discussions
Is there a straightforward migration or export path from Tailscale's official service to Headscale?
Currently, there is no automated migration tool to export device states or ACLs from Tailscale's cloud to Headscale. Users typically need to manually onboard devices to Headscale by generating new keys and re-authenticating clients. ACL policies must also be recreated manually. The community is actively discussing tooling improvements, but migration remains a manual process.

ZeroTier FAQ
Can ZeroTier be fully self-hosted to avoid using their root servers for network coordination?
Yes, ZeroTier offers an open-source controller called ZeroTier Central which you can self-host to manage your own network coordination and identity services. However, setting this up requires additional infrastructure and networking expertise since you must handle controller redundancy, security, and updates yourself. The default public root servers are used for convenience but self-hosting is supported for full control.
Community insight informed by Reddit discussions
Does ZeroTier support offline or air-gapped network operation without internet access?
ZeroTier’s peer-to-peer architecture allows devices to communicate directly once they have exchanged network credentials and identities. However, initial authentication and network configuration typically require access to the root servers or a self-hosted controller. After setup, devices on the same LAN or VPN can communicate offline, but adding new devices or changing configuration without internet access is not supported.
Community insight informed by Hacker News discussions
Who owns the data transmitted over ZeroTier networks? Is any metadata or traffic routed through ZeroTier servers?
ZeroTier uses a peer-to-peer encrypted mesh network, so all user data traffic flows directly between devices whenever possible. The root servers only facilitate initial handshake and network coordination metadata but do not see or store user traffic. Thus, data ownership remains with the users, and ZeroTier does not have access to the content of the communications.
Community insight informed by StackOverflow discussions
Are there any limitations or rate limits on the ZeroTier API for managing networks programmatically?
The ZeroTier API allows full network and member management but enforces rate limits to prevent abuse, typically around 1,000 requests per hour per account for the public controller. For enterprise or self-hosted controllers, these limits can be adjusted. The API is RESTful and supports JSON, but complex automation may require handling pagination and retry logic due to these constraints.
Community insight informed by Forums discussions
Is there a way to export or migrate ZeroTier network configurations to another controller or service?
ZeroTier does not provide a direct export/import feature for entire network configurations. However, you can export network member lists and settings via the API or controller UI and then recreate them on another controller manually or via scripts. Migrating between public and self-hosted controllers requires rejoining devices to the new network since cryptographic identities are tied to the controller.
