Cursor
The AI-native code editor now valued at $29.3B and used by pros
Cursor is the world's most popular AI-first code editor, built by Anysphere (a $29.3B company as of 2025) and forked from VS Code. It understands your entire codebase via semantic indexing, edits multiple files at once, and ships Composer 2.5 (May 2026) for autonomous multi-step tasks. The Pro plan at $20/month includes unlimited Tab completions, extended Agent limits, and $20 of frontier-model usage credits. For 2026 it added Cloud Agents and Design Mode with visual prompts.
