Cursor

Cursor is an AI-first code editor built on VS Code's foundation, designed from the ground up for an AI-native workflow. It excels with powerful agent-like features: you can ask it to implement entire features, debug by highlighting errors, or refactor large codebases using natural language. It deeply indexes your entire project, providing exceptional context awareness beyond the current file. Its 'Composer' feature allows for complex, multi-step edits.

Aimed at developers seeking a highly interactive, agentic AI partner, it ranks highly for its proactive capabilities, speed, and focus on turning high-level instructions into production-ready code, often reducing the need for manual editing.
