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

Coder

  • Premium plan pricing is not published and requires contacting sales.
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs.
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls.
