The short version

  • Each has a real cost: Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Prettier

  • Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
  • Developers must format entire files rather than selective line ranges in some contexts
  • Limited language support compared to some alternatives, though it covers major languages

Trivy

  • Reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • No built-in triage or exception workflow, so suppressing accepted risk is managed in config files
  • Findings are point-in-time from CI, with no continuous runtime monitoring unless you add the commercial platform
