The Best Chrome Extensions for Designers and Developers in 2026
Curated by Musharof Chowdhury · Last reviewed · How we pick
Every extension can read some of what you do in the browser, so the best setup is a short list of trusted ones rather than dozens you forget about. This shortlist covers the extensions we think earn their place: privacy and security first, then tools for inspecting and capturing websites.
All but one are free; CSS Scan is a paid one-time purchase, included because nothing free matches it.
Our shortlist
Bitwarden

uBlock Origin Lite

Frequently asked questions
What are the most useful Chrome extensions?
+
A password manager such as Bitwarden and an ad and tracker blocker such as uBlock Origin Lite are the most useful for everyone. Developers and designers should add Wappalyzer, WhatFont and ColorZilla.
Does uBlock Origin still work in Chrome?
+
The original uBlock Origin no longer works in Chrome because Chrome dropped support for Manifest V2 extensions. uBlock Origin Lite is the Manifest V3 version made by the same developer, and it still blocks most ads and trackers. The original still works in Firefox.
Are Chrome extensions safe?
+
Most are, but extensions can request broad access to the pages you visit, and popular ones are sometimes sold to new owners who add tracking. Install only what you use, check the permissions requested and remove extensions you no longer need.
What are the best Chrome extensions for web developers?
+
Wappalyzer for seeing a site's tech stack, CSS Scan for inspecting styles, Responsive Viewer for testing layouts and GoFullPage for full-page screenshots. Lighthouse is built into Chrome DevTools, so it no longer needs an extension.
