Cursor shipped version 3.0 on April 2, ditching its VS Code-derived interface for something built from the ground up around AI agents. The core addition: an Agents Window that lets developers run dozens of coding agents in parallel across local machines, cloud VMs, remote SSH, and worktrees. You can switch back to the old IDE anytime, or run both side by side.
The angle here is orchestration. Agents launched from Slack, GitHub, Linear, or mobile all surface in a single sidebar. Cloud agents generate screenshots and demos of their work so you can verify without digging through diffs. A new handoff system lets you push a local agent session to the cloud when you close your laptop, or pull a cloud session down to your desktop for hands-on edits. There's also a Design Mode (Cmd+Shift+D) that lets you annotate UI elements in a built-in browser and feed that context directly to agents.
Cursor, built by Anysphere, says 35% of its PRs now come from agents running on their own VMs, a company-reported figure. Revenue reportedly crossed $2 billion annually according to Bloomberg, and the company was in talks for a $50 billion valuation as of March. The competitive pressure is real: Anthropic's Claude Code, OpenAI's Codex, and GitHub Copilot are all pushing deeper into agentic coding.
Cursor 3 ships with Composer 2, the company's own coding model, and a plugin marketplace with MCP integrations, skills, and subagents. Users can access the new interface via Cmd+Shift+P in the desktop app.
Bottom Line
Cursor 3 replaces its VS Code-based UI with a purpose-built agent workspace that runs parallel coding agents across local and cloud environments.
