The short version

  • Each has a real cost: Infisical free tier limited to 5 identities, suitable only for small teams or evaluation; Kubernetes complex initial setup and configuration with multiple interdependent components
  • They diverge on capability: Infisical covers Secrets management, Kubernetes covers Container orchestration.

Where each one falls short

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

Infisical

  • Free tier limited to 5 identities, suitable only for small teams or evaluation
  • Pricing tiers are per-identity, which scales costs with team size
  • Certificate management requires Enterprise plan for advanced features like wildcards
  • Privileged access tier is separate billing from secrets management

Kubernetes

  • Complex initial setup and configuration with multiple interdependent components
  • Significant resource requirements for both hardware infrastructure and specialized human expertise
  • Expensive specialized talent in Kubernetes domain; hiring costs prohibitive for many organizations
  • New security challenges around container isolation and network security requiring robust measures
  • Requires continuous maintenance and updates to stay current with releases and security patches
