Every extension you install adds startup time and a little risk, so the goal is the smallest set that genuinely improves your day: a linter, a formatter, language support, version control help, and one AI assistant. Below is the set worth installing, a sample config to wire it together, and the categories you can safely skip.\n\n## The lean core worth installing\n\n| Category | What it does | Why it earns a slot |\n| --- | --- | --- |\n| Linter (e.g., ESLint) | Flags bugs and bad patterns as you type | Catches errors before you run anything |\n| Formatter (e.g., Prettier) | Auto-formats on save | Ends style debates and diffs noise |\n| Language support | Syntax, IntelliSense per language | Real autocomplete and type hints |\n| Git enhancement (e.g., GitLens) | Inline blame and history | Understand who changed what and why |\n| AI assistant | Inline suggestions and chat | Speeds boilerplate and explanations |\n| EditorConfig | Shared whitespace and EOL rules | Keeps teams consistent across editors |\n\n## A sample format-on-save config\n\nWire the formatter to run automatically so you never think about it. Put this in your workspace settings file. Note the comment style uses double slashes, never a hash:\n\n```json\n{\n  // format every file when you save it\n  \"editor.formatOnSave\": true,\n  // let the linter auto-fix on save too\n  \"editor.codeActionsOnSave\": {\n    \"source.fixAll\": \"explicit\"\n  },\n  // pick a default formatter so VS Code does not ask each time\n  \"editor.defaultFormatter\": \"esbenp.prettier-vscode\",\n  // keep startup fast by not auto-updating mid-session\n  \"extensions.autoCheckUpdates\": false\n}\n```\n\nAnd a minimal lint setup script using shell comments:\n\n```bash\n// shell comments below use double slashes to stay valid as markdown\nnpm install --save-dev eslint prettier\nnpx eslint --init\n```\n\n## How to choose extensions\n\n1. **Start from empty and add on need.** Install an extension when you hit a real friction, not preemptively.\n2. **Prefer one tool per job.** One linter, one formatter, one AI assistant. Duplicates fight each other.\n3. **Check the maintenance signals.** Recent updates, open issue responsiveness, and download counts tell you if it is alive.\n4. **Disable per-workspace what you do not need everywhere.** A Python extension does not need to load in a frontend project.\n5. **Audit quarterly.** Uninstall anything you have not consciously used in a month.\n\n## What to skip\n\n- **Theme and icon pack overload.** One theme, one icon set. The rest is decoration that slows startup.\n- **Extensions duplicating built-ins.** VS Code now has strong Git, search, and refactoring built in; do not re-add them.\n- **Abandoned extensions.** No update in a year and a pile of open bugs means trouble. Move on.\n- **Three AI assistants at once.** Pick one, learn its shortcuts, and stop. Stacking them just adds noise and cost.\n\nIf you are choosing between editors entirely, our [VS Code versus Cursor comparison](/blog/vscode-vs-cursor-2026) breaks down when an AI-first fork is worth switching to.\n\n## FAQ\n\n**How many VS Code extensions should I have?**\nAs few as do real work, often under ten. Each one adds startup time and potential conflicts, so install on need rather than collecting them.\n\n**Do extensions slow down VS Code?**\nYes, especially at startup and in large projects. The built-in extension performance tools let you see which ones cost the most load time so you can prune.\n\n**Are AI coding extensions worth it?**\nFor most developers, one is genuinely useful for boilerplate and explanations. The value drops fast when you stack several; pick one and learn it well.\n\n**Should I sync my extensions across machines?**\nYes. The built-in Settings Sync keeps your lean set and config consistent, which is far better than reinstalling by memory.\n\n## Where to go next\n\nTune the rest of your setup and skills: [the best coding laptops to run it on](/blog/best-coding-laptops-2026), a [VS Code versus Cursor breakdown](/blog/vscode-vs-cursor-2026), and [how to debug code faster](/blog/how-to-debug-code-faster-2026).","hue":212,"metaTitle":"Best VS Code Extensions 2026: Install These","metaDescription":"The best VS Code extensions in 2026, kept lean.
