Cursor
AI-first code editor by Anysphere on VS Code. Cursor Tab, Cmd+K, agentic multi-file editing. Supports Claude, GPT-4, Gemini. Fast-growing Copilot alternative. Valued $9B+.
Cursor, Anysphere's AI-first VS Code fork, is no longer a niche alternative—it's a $9B+ juggernaut challenging GitHub Copilot and Claude Code on two fronts. Backed by SpaceX, Nvidia, a16z, and Thrive Capital, Cursor ships fast: its own Instant Grep, agentic multi-file editing, and support for Claude, GPT-4, and Gemini. The graph shows it's both a competitor and a dependency—products like MMX-CLI, Mind, and The Agency all rely on it, while it consumes Model Context Protocol and CLAUDE.md. But tensions are rising: Cursor competes directly with Anthropic (its model supplier) and Claude Code, creating an awkward co-opetition. As Claude Code enforces API tiers and 10x cost hikes, does Cursor's multi-model strategy become its moat—or a fragility when model access tightens?
