Cursor AI

Cursor is an AI-native code editor built as a fork of VS Code, developed by Anysphere. Unlike GitHub Copilot (a plugin), Cursor integrates AI at the editor level — enabling multi-file editing via Composer, autonomous agent mode, and deep codebase indexing. Enterprise customers include Stripe, Shopify, and Airbnb. Cursor raised $100M in a Series B at a $2.5B valuation in February 2026. Its market share surge has forced GitHub to accelerate Copilot Workspace development. Model flexibility (GPT-4o, Claude, local models) differentiates it from competitors.
