  • Separate charges apply from AI providers (OpenAI, Anthropic, etc.) using customer's own API keys, adding external costs

Penpot

  • Self-hosting requires Linux server and Docker knowledge for technical setup
  • Real-time collaboration features may have performance issues with very large design files
