What you give up either way

  • App Store listing polish and existing user reviews/ratings
  • Any proprietary prompts, tuned models, or provider contracts the vendor uses
  • Built-in moderation/abuse heuristics and analytics the published app may include
  • Existing in-app purchase history and live funnel/marketing optimization

An open-source project doing the core job proves a replacement is possible. It does not prove it matches RoastGPT, and it does not prove anyone has run it for a month. How we decide.
