Frequently Asked Questions
Is Cursor better than VS Code?
For AI-assisted coding workflows, Cursor is better than VS Code because its AI is natively integrated and codebase-aware. However, VS Code has a far larger extension marketplace and is completely free. Cursor is built on VS Code, so you get all VS Code extensions when you switch — minus a small number of marketplace-exclusive ones.
Why is JetBrains so expensive?
JetBrains charges $249/year because each IDE ships with deep language-specific intelligence: smart refactoring, framework-aware completions, built-in database tools, and profilers. The All Products Pack ($299/yr) covers all 12 JetBrains IDEs. Many employers cover this cost — it's worth asking your company.
Is Zed ready for production use in 2026?
Zed is production-ready for most developers in 2026, especially those using TypeScript, Go, Rust, or Python. Its main limitation is a smaller extension ecosystem (~200 extensions vs VS Code's 30,000+). If you depend on a niche extension, check compatibility before switching.
Can I use my VS Code extensions in Cursor?
Yes. Cursor is built on VS Code's codebase and supports the majority of VS Code extensions via the Open VSX Registry. Most popular extensions (ESLint, Prettier, GitLens, Docker, etc.) work identically. A small number of Microsoft marketplace-exclusive extensions may not be available.
Which IDE is best for Python development?
PyCharm (JetBrains) is the gold standard for Python with built-in Django/FastAPI support, advanced debugging, and intelligent inspections. VS Code with the Python extension is a strong free alternative. Cursor excels when you want AI to help write and refactor Python code across your whole codebase.
Is VS Code actually a full IDE?
VS Code started as a lightweight editor but has evolved into a full IDE for most purposes. With extensions, it gains debuggers, test runners, language servers, database tools, and Docker integration. For Java or Kotlin, dedicated JetBrains IDEs still provide deeper integration — but VS Code covers 90% of use cases.
How does Cursor's AI differ from GitHub Copilot in VS Code?
Cursor indexes your entire codebase for AI context — suggestions reference your actual types, functions, and patterns. Copilot in VS Code primarily works on open files with limited codebase awareness. Cursor's Composer feature edits multiple files simultaneously, which Copilot's Workspace feature only partially mirrors.
What IDE do most professional developers use in 2026?
VS Code remains the most popular IDE globally in 2026 with ~75% adoption in developer surveys. JetBrains tools are dominant in enterprise Java/Kotlin teams. Cursor has grown rapidly among AI-first developers. Zed is gaining traction in performance-focused teams and Rust developers.
