Cursor 3: The Unified Workspace for Building Software with Agents

Software development is rapidly evolving, and Cursor is at the forefront of this transformation. With the release of Cursor 3, developers now have access to a unified workspace designed specifically for building software with agents.

What is Cursor 3?

Cursor 3 introduces a new era in software development, moving beyond manual file editing to a world where fleets of agents autonomously ship improvements. The new interface is built from scratch, focusing on agent-first workflows and providing a higher level of abstraction, while still allowing developers to dig deep when needed.

Key Features

• Multi-Workspace Support: Seamlessly work across different repositories with both humans and agents collaborating in one place.
• Parallel Agent Management: Easily run and monitor multiple agents—local or cloud-based—directly from the sidebar, including those started from mobile, web, desktop, Slack, GitHub, and Linear.
• Fast Handoff Between Local and Cloud: Move agent sessions between environments with a single click, enabling smooth transitions for editing, testing, or running long tasks.
• Composer 2 Model: Take advantage of Cursor’s own frontier coding model with high usage limits for rapid iteration.
• Integrated Diffs and PR Management: Edit, review, stage, commit, and manage pull requests with a streamlined UI.
• Deep Code Understanding: Dive into files, use go-to-definition, and leverage full LSP support for in-depth code exploration.
• Built-in Browser and Plugin Marketplace: Open and prompt against local websites, and extend agent capabilities with hundreds of plugins from the Cursor Marketplace.

Why Cursor 3 Matters

Cursor 3 combines the best of traditional IDEs with cutting-edge agent-first capabilities. It’s designed to make coding with AI more powerful, collaborative, and efficient. The platform lays the groundwork for more autonomous agents and better team collaboration, while continuing to invest in the IDE experience until codebases become self-driving.
