Pros
  • Surgical control over which files and instructions go into each prompt
  • Side-by-side comparison across GPT-4o, Claude, Gemini, DeepSeek

  • Token counter prevents silently blowing past model context windows
  • One-prompt → live app
  • Auto-deploys
  • Great for non-engineers
  • Self-corrects errors
Cons
