The short version

  • Each has a real cost: Ory Kratos headless means you build every screen, which is significant work compared with a hosted login page; WireGuard manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • Prices and features above were last checked on 29 August 2026.

Nothing recorded that Ory Kratos does not also cover.

What people use each for

The jobs each tool is most often brought in to do.

Ory Kratos

  • Products needing complete control over the look and flow of authenticationnot WireGuard
  • Applications that must not hand user identity data to a third partynot WireGuard
  • Teams building identity as infrastructure across several servicesnot WireGuard

WireGuard

  • Site-to-site VPN connectivity for datacentres and branch officesnot Ory Kratos
  • High-performance VPN applications requiring minimal latency and CPU overheadnot Ory Kratos
  • Embedded systems and IoT devices with strict memory and storage constraintsnot Ory Kratos
  • WireGuard-based managed services (Tailscale, Mullvad VPN) providing abstraction over raw protocolnot Ory Kratos
  • Kernel module for Linux-based VPN appliances and firewallsnot Ory Kratos
  • Research and development in cryptographic protocol designnot Ory Kratos

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ory Kratos

  • Headless means you build every screen, which is significant work compared with a hosted login page
  • More moving parts than a monolithic IAM: Kratos handles identity, and OAuth2 needs Ory Hydra alongside
  • Documentation assumes real familiarity with identity concepts and is not a gentle introduction
  • Self-hosting identity carries the security and availability burden that hosted providers absorb

WireGuard

  • Manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • No built-in support for address allocation or DHCP; all IP assignments must be manually configured
  • Limited to UDP; TCP encapsulation requires wrapper tools, making it unsuitable for environments blocking UDP
  • Stateless protocol design means lost packets trigger peer disconnection rather than transparent reconnection
  • Requires operational expertise to securely configure and deploy; not suitable for non-technical users without wrapper tools (Tailscale, Mullvad)

Answered from the vendors’ own pages

Ory Kratos: Is Ory Kratos free?

Yes, open source and free to self-host. Ory Network is a paid managed service.

WireGuard: Is WireGuard free?

Yes, WireGuard is free and open-source software. The Linux kernel module is licensed under GPLv2; implementations for other platforms use MIT or Apache 2.0 licences. There are no licensing fees.

Ory Kratos: What does headless mean here?

Kratos provides identity flows as APIs and no user interface. You build the login, registration and recovery screens yourself.

WireGuard: How does WireGuard differ from IPsec and OpenVPN?

WireGuard replaces complex negotiation protocols and state machines with simple public-key cryptography. Its code is roughly 100 times smaller than IPsec, making it faster to audit, deploy, and maintain. It uses modern cryptographic primitives rather than legacy algorithms.

Source
Ory Kratos: Does Kratos do OAuth2?

No. Kratos handles user identity; OAuth2 and OpenID Connect provider functionality is Ory Hydra, a separate component.

WireGuard: Can I use WireGuard for a commercial VPN service?

Yes. Several commercial VPN services (Mullvad, IVPN, ProtonVPN) use WireGuard as their underlying protocol. You must implement peer management, key distribution, and endpoint selection on top of the WireGuard protocol.
