Cursor is an AI-native code editor forked from VS Code that pairs a familiar IDE with deep model integration, agent mode, and multi-file edits. In 2026 it is the most widely used AI coding tool in professional engineering teams, with Anysphere (its maker) reporting over $500M ARR as of early 2026 per Bloomberg.
Cursor is a standalone desktop editor built as a fork of Visual Studio Code. It preserves VS Code's extension ecosystem and keybindings while adding a first-class AI layer — inline completions, chat, and an autonomous agent that can plan, edit, run commands, and verify its own work across many files.
Anysphere disclosed in a March 2026 blog post that Cursor crossed 1 million daily active developers. Stack Overflow's 2026 Developer Survey listed Cursor as the most-used AI dev tool at 41% adoption — ahead of GitHub Copilot (38%). Engineering blogs from Shopify, Notion, and Ramp have publicly credited Cursor with measurable velocity gains; Ramp's CTO shared a 32% reduction in cycle time for feature work in a January 2026 LinkedIn post.

Anysphere raised a $900M Series C in May 2025 at a $9B valuation per Reuters, and they have not yet raised prices — most teams treat Cursor as one of the highest-ROI software expenses of 2026.
Is Cursor better than GitHub Copilot? For agentic multi-file work, yes — Copilot's agent mode launched later and still trails in benchmarks. For pure inline completion, they are close.
Does my code get used to train models? Not on Pro or Business if Privacy Mode is enabled. Default Business plans have Privacy Mode on.
Can I use my own API key? Yes, bring-your-own-key works for OpenAI, Anthropic, and others — useful for enterprise procurement.
Does Cursor work offline? The editor works; AI features require an internet connection unless you configure a local model endpoint.
How does Cursor compare to Claude Code? Cursor is an IDE; Claude Code is a CLI. Many developers run both.
If you write code for a living in 2026, Cursor has earned default-install status. The combination of VS Code familiarity, agent mode, and aggressive model iteration is hard to beat.
