The short version

  • Only Helm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Helm licensed under Apache License 2.0 per the project's GitHub repository (helm/helm LICENSE); as open source software it has no paid tier or vendor price to compare; KnowBe4 published prices assume a three year term, so the quoted per seat rate depends on a long commitment
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Helm

  • Licensed under Apache License 2.0 per the project's GitHub repository (helm/helm LICENSE); as open source software it has no paid tier or vendor price to compare
  • Contributors must sign commits under the Developer Certificate of Origin to have them accepted, per helm.sh, a process requirement not all Kubernetes tools impose

KnowBe4

  • Published prices assume a three year term, so the quoted per seat rate depends on a long commitment
  • Pricing is banded by seat count, and the lowest band of 25 to 50 seats pays the highest rate
  • Accounts above 1,000 seats have no published price and require a custom quote
  • Third party integrations, Compliance Plus and PhishER Plus are all separately priced per seat add ons
  • The Foundation tier carries 200 training modules against more than 1,000 on Advanced, so content volume is the main gate
