• Shields.io supports over 300 service integrations — from npm download counts to code coverage — all rendered as SVGs for crisp display at any resolution.

FAQ

What styles are available?

flat (default), plastic, flat-square, for-the-badge, social. Preview each to see which fits your README aesthetic.

Can I use custom logos?

Yes — Shields supports SimpleIcons slugs (github, npm, docker). Paste the slug and the logo appears next to the label.

Does it cache?

Shields.io caches server-side for performance. Badge values update every few minutes — instant updates aren't expected.

What about dynamic badges?

This generator builds static-style badges (hardcoded label + message). For dynamic badges (version from package.json, build status from CI), use Shields.io's dynamic endpoint URLs.
