Cursor 3.0 Introduces New Interface

• Cursor released Cursor 3 on 2 April 2026, adding an Agents Window that runs many agents in parallel across repos and environments: locally, in worktrees, in the cloud and over remote SSH^[1]
• Open it with Cmd+Shift+P then "Agents Window"; the classic IDE stays available and both can be open at once^[1]
• Cursor's blog says the interface was built from scratch rather than extending its VS Code fork, with all local and cloud agents (including ones started from mobile, web, Slack, GitHub and Linear) listed in one sidebar^[1]; InfoQ calls this a change in direction^[3]

Notable features

• Design Mode lets you annotate and target UI elements in the built-in browser (Cmd+Shift+D to toggle, Shift+drag to select an area), and Agent Tabs show several chats side by side or in a grid^[1]
• New /worktree and /best-of-n commands run a task in an isolated git worktree or in parallel across several models and compare results; cloud agents were removed from the Editor^[1]
• A new Await tool lets agents wait for background shell commands and subagents, and Enterprise admins gained a switch to disable "Made with Cursor" attribution^[1]

Reception and context

• InfoQ reports usage had inverted: in March 2025 about 2.5 times as many users used tab completion as agents, and now about twice as many run agents, and it cites CNBC for 35% of merged PRs at Cursor being written by cloud agents; it also notes Cursor publishes no latency figures for local-to-cloud handoff^[3]
• Reaction on Reddit and Hacker News was split, with some users saying the agent view loses their connection to the code, and one unverified claim of about $2,000 a week on premium models^[3]; a reviewer found Background Agents work best on well-scoped tasks and called review of their output mandatory^[4]
• Cursor's maker Anysphere, based in San Francisco, was later bought by SpaceX: the deal closed on 14 August 2026 and Cursor is now a SpaceX-owned product^[2]
