Cursor is the strongest fit here because it is an AI-powered code editor that can take your idea, help you plan the structure, generate the initial code, and explain each step as you build, all inside a familiar editor environment. It handles HTML, CSS, JavaScript, Python, and most popular frameworks, so it works regardless of which stack you end up choosing. Windsurf is a solid alternative at a lower price point if budget matters, and GitHub Copilot integrates directly into VS Code if you already use that editor. Claude Sonnet is worth considering if you want to have a detailed planning conversation about architecture and technology choices before writing a single line of code.
