The short version

  • Each has a real cost: Argo CD licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare; Preact compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose

Where each one falls short

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

Argo CD

  • Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
  • The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.
