Our take— Replit wins
Based on our comparison of published pricing, features, and compliance data, Replit pulls ahead with multi-factor authentication and a no-training-on-your-data policy. Devin stays close but doesn't lead on any single attribute here. Replit scores 7.8/10 to Devin's 7.8/10. Pick Replit if multi-factor authentication matters; Devin is the pick if it doesn't.
