Frequently Asked Questions

What's the most important extension for freelance work?

It depends on your workflow, but screenshot and annotation tools (for client communication) and color/font identification tools (for brand matching) tend to be used daily. Frontend Hero bundles many of these into one extension, reducing clutter.

How do I match a client's brand colors without their style guide?

Use a color picker extension to sample colors from their existing website, marketing materials, or logo. Frontend Hero's color picker can output colors as HEX, RGB, HSL, or even Tailwind classes if you're using Tailwind.

How can I show clients website issues professionally?

Use Lighthouse to generate performance/accessibility reports (looks professional, comes from Google). Use screenshot tools with annotations to highlight specific issues. Screen recordings are great for explaining complex problems.

Should I use free extensions or invest in paid tools?

Free extensions work fine individually, but you'll end up with 6-8 extensions cluttering your browser. Frontend Hero at $59 one-time replaces most of them with one professional tool. For freelancers billing hourly, the time savings pay for itself quickly.
