Cursor 3 is a major version release that transforms the AI coding editor into a full agent coordination platform. The headline feature is a unified workspace: every agent session — whether triggered from mobile, web, Slack, GitHub, Linear, or locally — appears in a single sidebar. You can see all running agents, their current state, and switch between local and cloud execution seamlessly. The release also introduces a marketplace for agent plugins and MCP (Model Context Protocol) servers, enabling a third-party ecosystem of specialized tools that agents can discover and use. The PR and diff interface has been completely redesigned for multi-agent workflows, with visual conflict resolution when multiple agents modify related code. Cursor has been on a remarkable trajectory — from a VS Code fork to the dominant AI IDE to now positioning as an agent orchestration layer. Cursor 3 is the clearest statement yet that the endgame isn't a better text editor; it's a platform where humans and AI agents collaborate on software production at scale.

Reviewer scorecard
“The unified agent session sidebar alone justifies the upgrade. I had three parallel agents running — one on tests, one on docs, one on a new feature — all visible and manageable from one interface. The MCP marketplace is early but the architecture is right. Ship.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Cursor keeps adding layers of complexity that raise the subscription ceiling without meaningfully improving the core coding experience for most developers. The $200/mo Ultra tier is real money, and the marketplace creates a fragmented dependency tree. This is a power-user upgrade, not a universal one.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“Cursor 3 is building the operating system for software development. When every trigger source — Slack message, GitHub issue, Linear ticket — can spin up a coordinated agent team and you manage them from one place, we've crossed into a new paradigm for how software gets made.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
“Managing agent sessions from mobile is genuinely useful — I can kick off a design system refactor before bed and review the diff in the morning. The redesigned PR interface makes agent-generated code much easier to review visually. Strong upgrade.”
