Cursor 2 is the AI-powered code editor upgrade with Composer, multi-agent workflows, and browser debugging. Discover features, usage guides, comparisons, and FAQs tailored for developers.

Cursor 2 is an open and extensible AI-powered coding platform designed to accelerate software development through parallel agent execution, robust sandboxing, and seamless collaboration. The system orchestrates multiple AI agents running in parallel, each operating in isolated worktrees or remote environments to prevent cross-talk and minimize conflicts. A core feature is the Composer coding model, optimized for complex, multi-step programming tasks, which can be deployed alongside other models for best results. The platform includes an embedded browser for live agent testing, comprehensive code review tooling, and a flexible plugin architecture that connects to external data sources and APIs. This combination enables teams to prototype rapidly, iterate on solutions with auditable provenance, and scale development workflows beyond traditional single-agent paradigms.
