Cursor

Cursor is an AI-first code editor built on VS Code that has become the tool of choice for AI-augmented development among professional engineers. Its defining capability is deep codebase understanding — Cursor indexes your entire repository and makes that context available to the AI for suggestions, refactors, explanations, and multi-file edits that understand how all parts of your code connect.

Composer mode is the standout feature: describe a feature, bug fix, or refactor in plain language, and Cursor makes coordinated changes across dozens of files simultaneously, showing you a diff of every change before you accept. This is fundamentally different from one-file-at-a-time autocomplete tools and makes large-scale refactoring — renaming a data model, migrating to a new library, or restructuring an entire module — dramatically faster.

Cursor supports any language or framework that VS Code supports and imports all your existing settings, extensions, and keybindings. The Pro plan costs $20/month after a two-week free trial. The main trade-offs are cost and resource usage — Cursor is noticeably heavier than plain VS Code and can slow down on older machines. For professional developers working on real codebases, the productivity gains typically justify both the cost and the resource overhead.
