Why frontend is HARDER for AI than backend (and how to fix it)

AI coding agents struggle more with frontend than backend development because they lack visual feedback loops. Backend code benefits from text-based testing and error messages that LLMs process well, while frontend requires visual inspection of UI changes, animations, and user interactions. The solution involves integrating browser automation tools like Chrome DevTools MCP or Playwright MCP, allowing AI agents to screenshot and interact with running applications. This visual feedback dramatically improves AI's ability to handle complex frontend tasks by mimicking how human developers test their work.
