Cursor 3 (codename Glass) marks a fundamental shift in AI-assisted development: the traditional IDE is demoted to a fallback while an agent management console becomes the primary interface. Built from scratch, it features multi-repo workspaces, a unified sidebar aggregating agents from mobile, web, Slack, GitHub, and Linear, and a Cloud Handoff feature enabling seamless session portability between local and cloud environments. The release comes amid competitive pressure from Claude Code's $2.5B run rate and developer churn. Cursor also shipped its own in-house model (Composer 2), Automations for event-triggered agents, and self-hosted cloud agents — all within a single month. The broader industry is converging on agent orchestration as the new primary developer surface, but disagrees on architecture: Anthropic went terminal-first, OpenAI went multi-surface, Google's Antigravity treats editor and agent console as coequal, while Cursor makes the agent console the default. This shift changes the developer's role from writing code to orchestrating agents, reviewing diffs, and managing workflows — converging with the work of a systems operator.
