Visual Studio Code

Visual Studio Code is a free code editor from Microsoft that somehow became the default development environment for most of the industry. The Stack Overflow Developer Survey has consistently placed it at #1 since 2018, and by 2026 it commands roughly 70% market share among code editors. It runs on Electron (Chromium + Node.js under the hood), which means it's cross-platform—same editor on macOS, Windows, and Linux—but also means it's heavier than truly native alternatives. What makes VS Code dominant isn't any single feature. It's the combination: IntelliSense that actually works across dozens of languages via the Language Server Protocol, a built-in debugger that handles Node.js, Python, Go, C++, and more, Git integration tight enough that many developers never open a standalone Git client, and an extension marketplace with over 50,000 extensions covering everything from Prettier to Kubernetes management. The editor strikes a balance that's hard to beat—lighter than a full JetBrains IDE, more capable than Sublime Text or Vim out of the box, and free. On macOS specifically, VS Code runs as a native Apple Silicon binary since version 1.54 (February 2021). Memory usage typically sits at 300-600MB depending on how many extensions you've loaded. Startup time is around 1-2 seconds on an M-series Mac, which is slower than Zed or Sublime Text but fast enough that most people don't notice. The real cost is extension bloat: install 40+ extensions and you'll feel the sluggishness creep in. Power users learn to keep their extension count lean and use workspace-specific extension recommendations to avoid loading everything globally.
