About TailscaleGuide
TailscaleGuide covers Tailscale as a mesh VPN: how the coordination plane, NAT traversal and DERP relays interact, tailnet policy and tag design, MagicDNS, subnet routers and exit nodes, why a peer link ends up relayed and what to do about it, and how the alternatives (ZeroTier, NetBird, Headscale) differ structurally rather than on features.
It is for people replacing a hub-and-spoke VPN with a mesh and wanting to keep the access model deliberate, and for people whose mesh already works but is slower than it should be. Sources are the Tailscale, NetBird, ZeroTier and Headscale documentation and the WireGuard protocol papers, cited on each page.

Start here
- How a Tailscale mesh VPN works - the model everything else on this site assumes.
- Tailscale setup guide - install to first tailnet, and closing the allow-all policy a new tailnet ships with.
- Why Tailscale throughput is slow - relayed paths, NAT traversal, UDP offload and the forwarding node.
- Tailscale vs ZeroTier vs NetBird - control plane, network layer and policy model compared.
- Latency and throughput estimator - model a direct, peer-relay or DERP path against your own numbers.
7 articles are published so far. New articles are announced on the RSS feed; there is no fixed publishing schedule and this site does not promise one.
How these articles are produced
Articles are researched from primary sources: vendor and project documentation, published standards and specifications, release notes, advisories, and measurements published by the people who took them. Drafts are produced with AI assistance and then edited against those same sources before anything is published. Where a figure comes from a datasheet or a third-party measurement, the article names the source and links to it so you can check the original rather than take this site's summary of it.
Everything here is published under the TailscaleGuide Editorial byline. That is an editorial desk, not a person, and no article on this site claims hands-on lab testing, benchmarking, or first-hand measurement. Nothing here should be read as a report of something this site physically tested.
Corrections
Getting it right matters more than getting it first. If something on this site is wrong, out of date, or missing the source it should cite, email hello@tailscaleguide.com with the page and the specific claim. Substantive corrections are made on the page itself rather than quietly dropped.
How this site is funded
This site currently runs no affiliate links, no sponsored content, no paid placement, and no display advertising. Nothing on it earns a commission. If that changes, this page and the disclosure page will say so before any such link appears.
The full position is on the disclosure page. Read it before acting on anything here that reads like a buying recommendation.
