Cursor 3 goes agent‑first

Cursor released Cursor 3 on April 2 with a new interface built around managing coding agents, not editing one file at a time. (cursor.com) Coding agents are software assistants that can take a task, write code, run commands, and report back. Cursor 3’s new “Agents Window” lets developers run many of those agents in parallel across repositories and environments, including local machines, worktrees, cloud sessions, and remote Secure Shell connections. (cursor.com) The company said the new workspace supports handoff between local and cloud agents, so a task can start on a developer’s computer and continue on remote infrastructure. Cursor’s April 2 launch post described the product as “a unified workspace for building software with agents.” (cursor.com) Cursor also tied the release to a plugin system that connects agents to outside tools and internal knowledge. Its marketplace, announced on February 17, packages Model Context Protocol servers, skills, subagents, rules, and hooks from partners including Amazon Web Services, Figma, Linear, and Stripe. (cursor.com) That marks a change in what Cursor is selling. InfoQ reported on April 16 that Anysphere, Cursor’s parent company, rebuilt the interface “from scratch” and shifted the main interaction model from file editing to coordinating parallel agents. (infoq.com) Cursor is not abandoning the older editor view. Its documentation says the classic integrated development environment remains available alongside the Agents Window, and the company said it will “continue to support and improve both experiences.” (cursor.com) The release also adds more explicit controls for isolated code branches, which developers use to test changes without touching the main project. Cursor’s April 2 notes said worktrees are now driven by commands such as “/worktree” and “/best-of-n,” which lets users compare multiple model outputs for the same task. (forum.cursor.com) Cursor has kept expanding the marketplace since launch. In March, the company said it added more than 30 new plugins from partners including Atlassian, Datadog, GitLab, Glean, Hugging Face, monday.com, and PlanetScale, and said team administrators on paid plans can manage private plugin catalogs. (cursor.com) The immediate test for Cursor 3 is whether developers want a coding workspace that acts more like an air-traffic controller for agents than a text editor with autocomplete. Cursor’s own release notes point to that bet: the new interface is “centered around agents,” while the editor stays as one option inside a larger workflow. (cursor.com)
