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

Pulumi

  • The free Individual plan allows one user and one concurrent stack update
  • The Team plan is $40 per month base including 40 credits, and caps the organisation at 10 users
  • SAML/SSO, RBAC, audit logs and drift detection require the Enterprise plan at $400 per month base
  • The per-resource rate rises from $0.1825 per resource per month on Team to $0.365 on Enterprise, so upgrading raises the unit price as well as the base fee
  • Managed secrets are billed separately at $0.50 per secret per month on Team and $0.75 on Enterprise
  • Self-hosting, SCIM user sync, audit log export and 24x7 support are only in Business Critical, which is custom priced with no published rate
  • Team includes up to 500 resources and Enterprise up to 2,000, with everything beyond billed on demand as credits
