The short version

  • Each has a real cost: KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite; kind requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host
  • They diverge on capability: KeystoneJS covers REST API, kind covers Nodes as containers.
  • 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.

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

kind

  • Requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host
  • Fewer conveniences than minikube: no addon system, so ingress and metrics need manual installation
  • Because nodes are containers sharing the host kernel, it is a weaker simulation of real node behaviour and storage

Speed and cost. A container node starts in seconds and uses far less memory than a virtual machine, which is what makes per-CI-run clusters realistic.

KeystoneJS: Does KeystoneJS offer paid support?

Enterprise support with tailored options is available from Thinkmill, the company behind KeystoneJS. Pricing details available upon request.

Source
kind: Is kind suitable for production?

No. It is a development and testing tool, and node isolation is weaker than real nodes because containers share the host kernel.
