Where each one falls short

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

Keygen

  • Specific Active Licensed User (ALU) pricing not listed; requires interactive pricing calculator
  • Whitelabel API add-on costs $995/year per domain

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)

Keygen runs on Web. WireGuard runs on Linux, Windows, macOS, iOS, Android, FreeBSD, OpenBSD.
Can I use Keygen for free?
Both have a free tier, so you can try either at no cost before committing.
What is Keygen best used for?
Keygen is most often used for software licensing and distribution, product release management, api-based license verification. Of those, software licensing and distribution and product release management are not what WireGuard is typically brought in for.

Answered from the vendors’ own pages

Keygen: Does Keygen have a free tier?

Yes, the Dev tier is free and supports up to 100 Active Licensed Users with 10 product releases and core licensing API access.

Source
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.

Source
Keygen: How is Keygen pricing calculated?

Keygen uses scalable, flat monthly or yearly fees based on your licensing volume (Active Licensed Users). No revenue share or transaction fees are charged.

Source
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
Keygen: Does Keygen charge for additional features like SSO?

SAML/SSO is included in Enterprise tiers. Whitelabel API support costs $995/year per domain. Premium Support SLA is $995/month for Enterprise.

Source
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.
