The Must-Haves
After testing hundreds of extensions, these 15 are the ones I install on every fresh VS Code setup.
🤖 AI & Intelligence
- GitHub Copilot — AI autocomplete that actually works. Worth every penny of the $10/month.
- Error Lens — Shows errors and warnings inline, right where the problem is. No more hovering over squiggly lines.
- IntelliCode — Microsoft’s AI that learns from your codebase patterns.
🎨 Code Quality
- ESLint — Linting JavaScript/TypeScript. Non-negotiable.
- Prettier — Auto-format on save. End all formatting debates forever.
- SonarLint — Catches bugs and security issues that ESLint misses.
⚡ Productivity
- Multi Cursor Case Preserve — Change casing while maintaining the original format across multiple cursors.
- Todo Tree — Find all TODOs, FIXMEs, and HACKs in your project in a sidebar panel.
- Auto Rename Tag — Rename HTML opening tags and closing tags update automatically.
- Path Intellisense — Autocomplete file paths in imports. Saves minutes daily.
🖥️ Visual & DX
- One Dark Pro — Still the best dark theme after all these years.
- Material Icon Theme — Beautiful file icons that make the explorer actually useful.
- Indent Rainbow — Colorizes indentation levels. Makes Python and YAML so much easier.
- GitLens — See who wrote each line and when. Inline blame, history, and comparisons.
🔧 Language-Specific
- Tailwind CSS IntelliSense — If you use Tailwind, this is mandatory. Autocomplete + color previews.
Honorable Mentions
- REST Client — Test APIs without leaving VS Code
- Docker — Manage containers from the sidebar
- Remote SSH — Edit files on remote servers as if local
- Thunder Client — Postman alternative inside VS Code
