Where each one falls short

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

Duplicati

  • No managed service or commercial support

  • No enterprise features

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
