Anysphere Launches Cursor 3, an Agent-First Workspace Integrated Into Its AI Code Editor

San Francisco-based Anysphere, parent of Cursor on April 2 released Cursor 3, a complete redesign of its AI-powered code editor built from the ground up around managing fleets of AI coding agents.

The new interface sits inside the existing desktop application and shifts the primary workflow from traditional code editing to directing, monitoring, and reviewing autonomous agents that handle feature implementation, testing, and deployment.

The update arrives as the company and the broader industry move deeper into what Cursor has described as the third era of AI software development, where agents tackle larger tasks independently over extended periods with minimal ongoing human input.

Engineers at Cursor already report that more than one-third of their own pull requests come from agents running on cloud infrastructure.

According to the company's official blog post, Cursor 3 creates a unified workspace that brings clarity to agent-generated work. It features a sidebar listing all active agents, whether launched from the desktop, mobile app, web, Slack, GitHub, or Linear.

Users can run multiple agents in parallel across repositories, with cloud-based agents automatically generating demos and screenshots for quick verification.

A key addition is seamless handoff between local and cloud environments.

Developers can shift an agent session from cloud to local for rapid iteration using Cursor's Composer 2 model or move a local session to the cloud to continue running offline.

The interface also includes an updated diffs view that streamlines editing, reviewing, staging, committing, and opening pull requests.

Jonas Nelle, one of Cursor's heads of engineering, said in an interview with WIRED that the profession has changed markedly in recent months.

"In the last few months, our profession has completely changed," Nelle stated. 

"A lot of the product that got Cursor here is not as important going forward anymore." Nelle added.

Cursor pioneered AI integration in a Visual Studio Code fork when it launched in 2023 and quickly became one of the largest customers of models from OpenAI, Anthropic, and Google.

The new release directly addresses the rise of dedicated agentic tools such as Anthropic's Claude Code and OpenAI's Codex, which have drawn developers with generous usage limits.

Cursor 3 differentiates itself by embedding the agent workflow inside a full development environment that retains access to files, language server protocol features, an integrated browser, and a marketplace for plugins that extend agent capabilities with custom tools and sub-agents.

The company continues to invest in its own models, including Composer 2, which it positioned as competitive on performance and cost for agentic tasks.

Users can activate the new interface immediately after updating the desktop app by opening the command palette and selecting "Agents Window."

The launch underscores Cursor's bet that the future of software development centers on developers acting as orchestrators of agent teams rather than individual coders.

The company has made the interface optional, preserving access to the original IDE layout for users who prefer it, but the core design now prioritizes agent management as the default experience.
