Cursor 3.1 (Composer Agents)
The industry-standard AI software engineering environment with autonomous multi-file Composer agents, repo-wide indexing, and zero-latency edits.
Genuine Editorial Review & Analysis
Cursor is a direct fork of VS Code engineered from the ground up for LLM-assisted software architecture. Its killer capability—Composer (Cmd+I)—indexes your entire repository via AST embeddings, allowing it to execute coordinated edits across dozens of files simultaneously. It effortlessly handles dependency migrations, test suite generation, and complex API refactoring with surgical precision.
