  • They diverge on capability: Trivy covers Multi-target scanning, Violentmonkey covers Userscript support.
  • 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.

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

Violentmonkey

  • Smaller script ecosystem compared to Tampermonkey which has larger user base and more available scripts
  • Less marketing and visibility results in lower adoption compared to more widely-known alternatives
  • Community maintenance model means slower feature development compared to commercial alternatives
