Cursor raised $900M at a $9B valuation in August 2024. Windsurf (formerly Codeium) sold to OpenAI for $3B in 2025. Sourcegraph Cody pivoted to full IDE. Three AI-native IDEs are now mature enough that picking between them is a real question — not "which one works" but "which fits your team's constraints on privacy, latency, and context depth". Stack Overflow's 2025 Developer Survey reported that 62% of professional developers now use an AI coding tool daily, up from 44% in 2024. The same survey showed the choice between tools matters more than the choice of editor: developer satisfaction swings ~20 points depending on which AI assistant, vs ~5 points for underlying editor.

This isn't a "which is best" verdict — it's a decision framework with numbers. We're going to be specific about where each one wins, where each one loses, and where our own IDE heartbeat data from teams running them in production (n=47 teams, ~340 developers) lines up with or contradicts the marketing claims.

The IDE debate is eternal. VS Code fans say it's fast and extensible. JetBrains loyalists swear by deep language support. And now Cursor is the new challenger, riding the AI wave. The Stack Overflow Developer Survey consistently ranks VS Code as the most popular editor, while the JetBrains Developer Ecosystem Survey shows strong loyalty among its users. But surveys measure sentiment, not reality.

What do developers actually use when they sit down to work? Not what they tweet about. Not what they starred on GitHub. What they code in, hour after hour, day after day.

We have the data. thousands of hours of tracked coding time across 100+ B2B companies, broken down by IDE.
