Where each one falls short

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

GitLab CI/CD

  • Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
  • Additional compute minutes beyond quota incur charges; exact pricing not specified

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

Public open-source projects receive a 0.5x discount on compute minutes. Public forks of GitLab open-source projects receive a 0.008x discount.

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.
