What service powers the badges?

The badges are generated by shields.io, a widely used free service that produces SVG and PNG badges. Your browser constructs the shields.io URL from your inputs — nothing is sent to Top10k servers.

What color formats are accepted?

You can use any valid shields.io color: hex codes (e.g. #4c1), named colors (brightgreen, blue, red, orange, yellow, lightgrey, success, critical, important, informational, inactive), or CSS color names.

How do I add a logo to my badge?

Enter a Simple Icons slug in the Logo field (e.g. "github", "npm", "typescript"). Visit simpleicons.org to find the correct slug for your desired brand icon.

Can I link the badge to a URL?

Yes. Enter a URL in the Link field and the Markdown snippet will wrap the badge image in a clickable anchor tag.

What badge styles are available?

shields.io supports five styles: flat (default), flat-square, plastic, for-the-badge (large uppercase), and social (GitHub-style).

Is the preview the actual badge?

Yes. The preview is a live <img> tag pointing to shields.io, so it renders the exact badge you will get in your README.
