Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
OpenVPN
- Open source OpenVPN, while free, requires real technical skill to configure, secure and maintain without the Access Server admin layer
- Per-connection billing on Access Server means usage spikes, such as an all-hands remote day, can push simultaneous connections over a licensed limit and block new connections until usage drops or the plan is upgraded
- OpenVPN's traditional hub-and-spoke architecture routes traffic through a central server, unlike mesh VPN tools like Tailscale or NetBird that establish direct peer-to-peer connections where possible, which can add latency
- Client configuration and certificate management for the open source version is more manual and error-prone than newer VPN tools with zero-config onboarding
- Access Server pricing above the Growth tier reverts to custom Enterprise quoting, so very large deployments lose the pricing transparency of the lower tiers
- The protocol's throughput is generally lower than newer kernel-integrated protocols like WireGuard under equivalent conditions, which matters for high-bandwidth use cases
Traefik
- No transparent pricing displayed for Traefik Hub API Gateway or API Management products
- No subscription period specified for paid tiers
- Traefik Hub products require contacting sales for pricing
