Evaluating AI-Driven “Vibe Coding” Tools

At CodeYam, we tested six advanced AI tools that convert natural language into software, focusing on their ability to build a moderately complex multi-page, mobile-responsive to-do app. Each tool was evaluated on its natural language input and output capabilities, using a structured prompt that included generating a product specification and considering missing functionality. The tools fell into three categories: detailed planners (e.g., v0, Lovable), lightweight planners (e.g., Firebase Studio), and opaque agents (e.g., Replit). Most tools provided MVPs but struggled with precise integration, particularly with Supabase, which varied in usability. Key insights included the need for efficient iterative workflows over one-shot builds, and the importance of QA, as deployment often presented unexpected discrepancies. While branding and testing support were generally lacking, the tools demonstrated potential for rapid prototyping. Overall, though promising, the platforms require refinement in usability and integration for broader professional adoption.
