Finding the right developer tools can save hours of work every week. Here are the best free Chrome extensions that every developer should have installed in 2026.
Stop squinting at minified JSON. A good JSON formatter automatically detects and formats JSON responses with syntax highlighting, collapsible trees, and clickable URLs. Look for one that's under 50KB — most popular ones are bloated at 2-5MB.
Our pick: FlowKit JSON Formatter — 5KB, zero tracking.
Every frontend developer needs a color picker. The best ones let you pick colors from any webpage, show hex/rgb/hsl values, and copy with one click.
Developer work means dozens of tabs. A tab suspender can save 80% of your browser's RAM by suspending inactive tabs. This is especially important on 8GB or 16GB machines.
Full-page screenshots for bug reports, design reviews, or documentation. The best tools don't require an account or upload your screenshots anywhere.
Reduce eye strain during long coding sessions. A good dark mode extension works on ALL websites, not just popular ones.
