WireGuard vs Tailscale vs Headscale: Which one to use?

WireGuard vs Tailscale: di short answer

WireGuard vs Tailscale no bi choice between two different protocol, sake of say Tailscale na WireGuard. Tailscale dey run di same encryption and di same tunnel, den e add control plane: one coordination server wey dey exchange public keys, dey give out addresses, dey punch hole pass NAT (network address translation), and dey apply access policy. You dey choose how much of dat coordination you wan run by yourself.

Three correct answer dey. Run plain WireGuard if you get one server and small clients wey all dey dial enter am. Run Tailscale if you want make every machine fit reach every oda machine without any config file wey you go dey maintain. Run Headscale if you want dat mesh but you no want third party make e hold your node list.

Wetin di control plane actually dey give you

Plain WireGuard no get discovery. Every peer na block of text wey you go write wit your hand: one public key, one AllowedIPs line, and one Endpoint if dat peer dey reachable. To add one machine join network of ten mean say you go edit ten config files, because each side need di oda side key. Na dat one make almost every self-hosted WireGuard setup dey be hub and spoke: one server wey get public IP, and clients wey only dey talk to dat one server.

Control plane dey remove dat editing work. Each node go register once, collect address from di 100.64.0.0/10 CGNAT (carrier grade NAT) range, and dem go tell am di public keys of di nodes wey e fit reach. Di tunnel still be direct WireGuard between two peers, and your traffic no dey ever pass through di coordination server. Wetin di server dey carry na metadata: who dey, which key be dia own, and who fit talk to who.

Three correct tins dey come out from dat one.

NAT traversal. Two laptops wey dey behind two home routers no get public IP between dem. Tailscale dey use STUN (session traversal utilities for NAT) to find each side outside address and port, den both sides go send packets for di same time so each router go see outgoing flow first and accept di reply. When dat one fail, traffic go fall back to DERP relay, wey be encrypted relay wey Tailscale dey run. Your data dey end to end encrypted through di relay, because di relay no dey ever hold di keys. Run tailscale status and each peer line go talk direct or relay. Run tailscale netcheck to see which relay dey nearest and weda your network allow UDP at all.

Key rotation wit expiry. WireGuard keys no dey ever expire. Key wey you issue three years ago go work forever unless you delete di peer block wit your hand. Tailscale dey expire node keys instead, and as of July 2026 di default expiry period on a new tailnet na 180 days. Machine wey no reauthenticate go stop to connect. You fit turn expiry off per device for server or subnet router wey nobody go dey around to log in.

Policy instead of routing. For plain WireGuard, AllowedIPs na di routing table and di access control list for di same time, so "alice fit reach di database" must be expressed as IP range. Tailscale dey keep separate policy file where rules dey name users, groups and tags. Rule fit talk say tag:laptop fit reach tag:db on port 5432 and noting else, and dat rule go still dey even if machine get new address.

Wetin di control plane dey cost you

Di coordination server sabi your network. E get every node public key, every node name, di addresses wey dem give out, and di policy. With hosted Tailscale, dat one na company wey no dey under your control. Dem no fit read your packets, sake of say di WireGuard private keys dey stay for your machines, but dem fit see how your network be, and whether you fit connect depend on say dia service dey up and your account dey good.

Another cost dey wey fit easy to miss. Tailscale na daemon for every machine, so e mean say na software wey you must dey patch for every machine. Plain WireGuard for Ubuntu 24.04 na kernel module wey dey come with di distribution and e dey update as di kernel update.

Di third cost na billing. As of July 2026, di Personal plan free with unlimited devices for up to 6 users, Standard na $8 per user per month, and Premium na $18 per user per month. Household plan dey free. Ten person team no dey free.

When plain WireGuard na di correct choice

Choose plain WireGuard if your network setup na hub and spoke. You get one VPS wey get public IP, plus three or four devices wey dey connect go dat VPS, and you no need make dem devices fit reach each other. Di config fit fit inside one screen, no daemon wey you go update, no account wey you go lose, and no third-party service dey stand between you and your server.

E still be di correct choice if you wan understand di layer wey every oda tin dey build on top. Self-hosting a WireGuard VPN on a VPS show how to generate key, wg0.conf, IP forwarding, NAT and handshake failures, and all dis mechanisms still dey run under any tailnet. If you still dey check di older option, WireGuard vs OpenVPN explain di four cases wia OpenVPN still get advantage.

Di install no long:

sudo apt update && sudo apt install -y wireguard
sudo modprobe wireguard && echo ok

Plain WireGuard come dey stress once every device must fit reach every oda device. Full mesh of N nodes go need N times N minus one peer blocks. If you get six devices, dat one na thirty blocks wey you go dey manage by hand, and if you duplicate AllowedIPs entry, e go silently thief traffic from di peer wey get am first, and e no go show any error for anywhere.

When Tailscale na di correct answer

Choose Tailscale wen di machines dey move-move. Laptops wey dey hotel networks, phone wey dey use mobile data, or home server wey dey behind router wey you no get control over. Dem be exactly di cases wey ordinary WireGuard no dey handle well, sake of say neither side get stable public endpoint wey you go fit put inside Endpoint.

To install di client, you go run one command from di official installer:

curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up
tailscale status

tailscale up go print one URL. Open am, log in, and di machine go join. No key dey wey you go copy and no inbound port dey wey you go open, sake of say di daemon dey make outbound connection to di coordination server and e dey keep am open. Na dat one make Tailscale node dey work for network wia you no get control over any firewall at all.

Two settings dey do most of di work wey dey useful afta dat. Subnet router dey advertise full LAN into di network so you no go need install di client for every device:

echo 'net.ipv4.ip_forward = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
sudo sysctl -p /etc/sysctl.d/99-tailscale.conf
sudo tailscale set --advertise-routes=192.0.2.0/24

Di route go dey inactive until you approve am for di admin console, and na so e suppose be: node no fit inject route into your network by imsef. Linux clients still need sudo tailscale set --accept-routes, sake of say Linux no dey accept advertised routes by default, so even if di route show say e don approve for server side, e no go do anything for Linux laptop until you set dat one.

Exit node dey send all di traffic of one client pass through one machine, and na dis be di full tunnel behaviour wey pipo usually mean wen dem talk "VPN":

sudo tailscale set --advertise-exit-node

When Headscale na di correct choice

Headscale na open source implementation of di coordination server, and e dey run for VPS wey you own. Di official Tailscale clients dey point go dia instead of di hosted service:

sudo tailscale up --login-server https://headscale.example.com

Everything about di data path no change. E still be WireGuard, and e still dey direct between peers where di network allow am. Wetin change be say di node list, di keys and di policy dey inside one SQLite file for disk wey you own. Nobody outside fit see how your network be, disable your account, or charge you money per user.

Di trade-off be say you go do real work. You dey run public HTTPS service now, wey mean say you need DNS name, certificate, and reverse proxy wey go fit pass WebSocket upgrades correct. You own di uptime, and if coordination server go down, new nodes no go fit register and existing nodes no go fit know about changes. Headscale still dey below version 1.0 and e minor releases don get breaking changes before, so make you read di changelog before you upgrade. Make you run Headscale as your own Tailscale control server cover di install, config.yaml, preauth keys and di ports wey you suppose open.

One warning dey wey dey catch pipo late. Headscale no come with Tailscale global relay network. Where two peers no fit connect direct, you go either enable di embedded relay for your own server or point di config go another one, and dat relay na just one box for one region instead of worldwide fleet. Peers wey dey far side of di planet go feel dat difference.

How to decide for one pass

Ask how many machines must reach each other. If the answer na say dem all just dey talk to the server, plain WireGuard dey need less software for the same result.

Ask whether the machines get stable public addresses. If most of dem dey behind NAT wey you no fit control, you go want control plane, because hole punching na the hard part and e no worth am make you dey rebuild am.

Ask who get permission to know how your network take be. If the answer exclude outside companies, or the number of users wey you get make per seat billing dey pain you, run Headscale and accept say you don become the person wey dey operate the control server.

You fit change your mind easily. Because the data plane na the same protocol for all the three, to move from plain WireGuard to a coordinated mesh na just client install, e no be redesign. And to move from Tailscale to Headscale na just re-registration of each node against a different login server.

Wetin none of di three no dey give you

None of dem na firewall. Tunnel dey decide which packets go pass, e no dey decide which services go listen. If server dey reachable through tunnel, e still dey reachable from internet for any port wey you open, so make you keep UFW firewall rules on the VPS dey do dia work. Tailscale policy file dey limit wetin oda nodes fit reach, but e no dey do anything for di public interface.

None of dem na per-service authentication, and none of dem na audit trail of wetin user do once dem connect. Treat all three as transport, and put di login checks inside di application.

FAQ

Tailscale na just WireGuard wey get extra steps?

Tailscale dey use WireGuard protocol for di data path, so di encryption and di tunnel na di same. Wetin e add na coordination: key exchange, address assignment, NAT traversal wit STUN and DERP relays, key expiry, and one policy file wey dey use user names instead of IP ranges. Dem be di parts wey plain WireGuard leave for your hand, and dem be di parts wey dey hard once machines start to move between networks.

My traffic dey pass Tailscale servers?

Normally no. Peers dey connect directly to each other once di coordination server don introduce dem, and tailscale status go show direct for those peer lines. When direct path no fit work, traffic go fall back to one DERP relay and di line go read relay. Even for dat time, di relay dey carry encrypted packets and e no get your WireGuard private keys, so e no fit read wetin dey inside. Run tailscale netcheck make you see weda your network dey block di UDP wey direct connections need.

I fit use Headscale wit di official Tailscale apps?

Yes. Headscale dey speak di same control protocol, so di official clients dey join wit sudo tailscale up --login-server https://headscale.example.com. You fit point desktop and mobile apps to one custom login server too, even though di setting dey different place for every platform, and na di mobile apps fit need specific version. Test one phone before you migrate your whole network.

I still need to open ports for Tailscale or Headscale?

One Tailscale client no need any inbound port, sake of say e dey dial out to di coordination server and e dey keep dat connection open. One self-hosted Headscale server need inbound ports: 443 for di control protocol, 80 if you use HTTP-01 certificate challenge, and 3478/udp only when you enable di embedded relay. Plain WireGuard need im UDP listen port, usually 51820, to dey open for di server and for any separate network firewall wey your provider dey run.

Which one among di three dey fast pass?

Throughput na di same, sake of say all three dey move packets wit WireGuard. Di difference dey show for connection setup and for path quality. Plain WireGuard wit correct Endpoint dey connect directly every time. Tailscale and Headscale dey connect directly most of di time and dey fall back to relay when di network block hole punching, and relayed path dey add latency. Measure your own path wit tailscale ping <node>, wey go report weda di route na direct or relayed, or wit iperf3 across di tunnel.
