Descriptions:
Cursor 3 introduces a significant shift in how developers interact with AI-assisted coding tools, and this video from Web Dev Cody walks through the major changes firsthand. The new interface moves away from the traditional file-tree-centric layout toward a multi-project, concurrent-agent experience — letting developers kick off multiple agent sessions across different projects simultaneously and monitor them from a unified panel.
The video demonstrates practical workflows including switching between models mid-task (Composer Too Fast for speed, GPT 5.4 for harder problems), using plan mode (triggered via Shift+Tab) to have the model reason through a bug before implementing a fix, and leveraging the built-in git diff viewer to review, stage, and push changes without leaving the editor. A real sprite animation bug in a top-down mining game serves as the running example throughout.
Viewers also get a look at Cursor 3’s integrated browser panel for web app testing and multi-terminal support. Cody notes he has been using Claude Code and Opus less in favor of working directly inside Cursor, citing a better overall developer experience. The video is a useful orientation for anyone already familiar with Cursor who wants to understand what changed in version 3 and how to adapt their agentic coding workflow accordingly.
