Possible disadvantages of replit

    While Replit offers a free tier, advanced features, higher resource limits, and premium support come at a subscription cost, which may be a barrier for some users.
  • Limited Debugging Tools
    The platform's debugging tools may not be as robust as those available in more established, dedicated IDEs.
