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

ESLint

Slow performance on large codebases compared to newer tools like Oxlint and Biome
Complexity in configuration from scratch, particularly for TypeScript support
Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
