Where each one falls short

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

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

WebStorm

  • JetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal
  • If the subscription lapses, use of new versions stops; JetBrains grants a fallback license only for the last version used while the subscription was active, per its published buy page
