10 Chrome Extensions Every Developer Should Try

Your browser is your most-used dev tool. The right extensions turn it from a window into a workbench. Here are ten that earn their place — no toolbar clutter, no spyware.

Debugging & inspection

• Framework DevTools — Whether you're on React, Vue, or Svelte, the official devtools extension is non-negotiable. Inspect component trees, props, and state the way you inspect the DOM.
• JSON viewer — Turns raw API responses into a collapsible, syntax-highlighted tree. You'll never paste JSON into a formatter again.
• A good color picker — Sample any pixel on the page, get the hex/HSL, and check contrast ratios for accessibility in one click.

Speed & navigation

• Keyboard-driven navigation (e.g. Vimium-style) — Follow links, scroll, and switch tabs without touching the mouse. There's a learning curve of about a day, and then you can't go back.
• A tab manager — Once you hit 40 open tabs, a manager that lets you search and suspend them is the difference between chaos and calm.

Privacy & inspection

• A request inspector — See and modify network requests on the fly. Invaluable for testing how your frontend handles slow or failing APIs.
• A cookie editor — Inspect, edit, and clear cookies per-site without digging through devtools panels.

Reading & reference

• A markdown previewer — Render .md files and GitHub readmes cleanly right in the browser.
• A reader mode — Strip the cruft from documentation pages so you can actually read the docs.
• A screenshot + annotation tool — Capture a full-page scroll, mark it up, and drop it into a bug report.

How to keep extensions safe

Extensions run with broad permissions, so a little discipline pays off:

1. Audit permissions before installing. "Read and change all your data on all websites" deserves scrutiny.
2. Prefer open-source extensions where you can read what they actually do.
3. Remove what you don't use — every active extension is attack surface.
