Keep your current setup if you only need a handful of fixed tunnels. Look elsewhere when you need more around the tunnel: mesh tools that hand out keys and handle sign-in suit teams with many people and devices, classic IPsec or SSL VPNs suit legacy and compliance setups, and zero trust access suits per-app rules instead of whole-network access.
WireGuard connects peers by swapping simple public keys, which its own page likens to swapping SSH keys, and it has grown from a Linux kernel project into a cross-platform tool. Sysadmins and small teams search for alternatives when that simplicity turns into a chore: handing out keys by hand to twenty laptops is a different job from linking two servers.
Many WireGuard alternatives run WireGuard underneath
A good share of what gets called an alternative isn't a different tunnel at all. Tailscale's product is built around it, NetBird builds a peer-to-peer network on it, and Headscale is a self-hosted version of Tailscale's control server. Moving to one of them often keeps the same tunnel and changes what sits around it. If you're weighing that exact move, our Tailscale comparison goes deeper.
So the real question is who manages keys, devices and sign-in. If that's the pain, you're shopping for a control layer, not a new VPN, and that narrows the list quickly.
There's a second reason to read the small print. WireGuard's own page says it's under heavy development. That isn't a reason to avoid it, but it is a reason to keep clients and servers updated and to read release notes before upgrading a whole fleet.
When staying put is the right call
Plenty of setups don't need anything else. If you link a few servers, or a couple of offices, and the list of peers rarely changes, a handful of keys in a config file is easy to reason about and easy to audit. Adding a control layer brings another service to run, another login to protect and, often, another vendor to trust.
The tipping point usually comes from people, not machines. Once staff join and leave every month, laptops get replaced and someone asks who still has access, hand-managed keys stop being simple. That's the moment to look at the groups below, not before.
Mesh networks with key handling built in
These suit teams of people and devices who need everyone connected without a sysadmin copying keys around.
Headscale
An open source, self-hosted implementation of the Tailscale control server. Pick it if you like the managed mesh model but want the coordination server on your own hardware.
NetBird
NetBird calls itself a zero trust networking platform, and it links devices directly to each other over WireGuard. Choose it when you want everyone meshed together and would rather run code you can inspect.
Tailscale
A commercial mesh product for teams who want a company behind their network. Its product is built around WireGuard and it runs a WireGuard for Enterprises offer for larger teams.
Overlay networks with their own design
These two describe themselves in their own terms, as an overlay tool and as software-defined networking, so judge each on its own design rather than as a layer over your current tunnels.
Nebula
A scalable overlay networking tool focused on performance, simplicity and security, by its own description.
ZeroTier
ZeroTier describes its product as software-defined networking, which suits people who think in terms of virtual networks rather than individual tunnels.
Classic VPN servers for compatibility
Sometimes the requirement comes from outside: a partner network, an auditor or an older firewall that expects a particular kind of VPN.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
OpenVPN
OpenVPN sells a self-hosted Access Server and a cloud-delivered option, so you can choose where the server runs. The trade-offs are set out in our OpenVPN head-to-head.
SoftEther VPN
SoftEther VPN pitches itself as a replacement for OpenVPN. Worth a look if you already run a classic VPN server and want to compare a different one.
strongSwan
An open-source, modular and portable IPsec-based VPN, available under GPLv2 or a commercial licence. The obvious pick when a partner or compliance rule expects IPsec.
Per-app access instead of a network
Sometimes the honest answer is that people don't need a network at all, only a few internal tools. Contractors, agencies and short-term staff are the usual examples: giving them one app is tidier than giving them everything.
Cloudflare Access
A zero trust network access (ZTNA) solution. Instead of putting someone on your network, you grant them access to the specific applications they need.
Nine options in one table

| ZeroTier | Overlay | Software-defined networking |
| OpenVPN | Classic VPN | Self-hosted Access Server or cloud-delivered |
| SoftEther VPN | Classic VPN | Pitched as an OpenVPN replacement |
| strongSwan | Classic VPN | IPsec, GPLv2 or commercial licence |
| Cloudflare Access | Zero trust access | Per-app ZTNA |
Pilot plan for a small team
Pick two candidates and give them a fortnight with real people before anything changes for everyone.
- Write down what's breaking: key distribution, sign-in, compliance or per-app control.
- If it's keys and sign-in, start with the mesh group; if an outside party needs IPsec, start with the classic servers.
- Set up both candidates on a spare machine and two or three volunteers' laptops.
- Add and remove a user in each and time it, because offboarding is where hand-managed keys hurt most.
- Connect from a phone on mobile data and from a restrictive network such as a hotel or a client's office.
- Check what you can see in the logs when a connection fails.
- Roll out to one team first, and keep your existing tunnels up until the new setup has run for two weeks.
Write the results on a single page: setup time, how long it took to add and remove someone, what broke and what users noticed. If neither candidate beats your current tunnels on the pain you named in step one, staying where you are is a perfectly good outcome, and you'll know exactly why.
Frequently asked questions
Is a mesh VPN the same as a traditional VPN?
Not quite. A traditional setup usually routes traffic through a central server, while a mesh lets devices connect to each other directly.
What should I check before letting contractors connect?
That you can remove their access in one step and see when they last connected. Shared keys or shared accounts make both of those hard.
What does Headscale change compared with the hosted version?
The control server, the piece that coordinates devices, runs on a machine you look after instead of one the vendor hosts. Check which client features it supports before moving a team over.
Can strongSwan be used under a commercial licence?
Yes. It's offered under GPLv2 or under commercial licensing, so a business has two routes; read the terms of each before building it into a product you sell.
Can Nebula grow with a bigger network?
Scale is part of its pitch, so it's a fair candidate if you expect many hosts. Pilot it at the size you plan to reach, not with three machines.
Can I mix tools, such as a mesh for staff and per-app access for contractors?
Yes. Nothing stops you using a mesh for your own team and Cloudflare Access for outsiders; just keep a single list of who can reach what.
