VS Code vs Cursor vs Windsurf: Which AI Code Editor Should You Use in 2025?

Three years ago, "AI code editor" meant a slightly smarter autocomplete. In 2025, it means an editor that can understand your entire codebase, rewrite files on command, explain errors in plain language, and generate multi-file features from a natural language description. The competition between VS Code, Cursor, and Windsurf represents three different philosophies about what that should look like in practice. This comparison cuts through the marketing to give you a realistic picture of what each editor does well, where it falls short, and who should be using each one.
