Tool Introduction

Generate shields.io badges for your README without remembering the URL format. Pick a preset — npm version, Docker pulls, GitHub Actions, license, coverage, or a custom static label — and copy ready-to-paste Markdown, HTML, or just the image URL.

Tool Overview

Shields.io is the de-facto badge service for open source READMEs, but its URL grammar is easy to forget and tedious to type. This tool wraps the most-used badge types in a friendly form, validates a live preview, and emits Markdown/HTML/URL output you can drop into any README, doc site, or PR template. Badges still render through shields.io, so they update automatically as your project changes.

Use Cases

  • Add a build-status badge to a GitHub README
  • Show npm version and weekly downloads on a package page
  • Display Codecov coverage in a PR template
  • Generate a custom "made with love" badge for a portfolio

Input/Output Examples

Live npm version badge with the npm logo and a flat-square style.
Input Intent
Preset: npm-version, package: react, style: flat-square
Output Intent
![react version](https://img.shields.io/npm/v/react?style=flat-square&logo=npm)

FAQ

Does the badge auto-update?+
Yes. Shields.io re-fetches the underlying source (npm registry, GitHub API, Docker Hub, etc.) at request time, so the badge stays current.
Can I use a custom logo?+
Yes. Any simple-icons slug works — type `github`, `docker`, `npm`, `python`, `rust`, etc. into the logo field.
What color values are supported?+
Named colors (brightgreen, blue, red, lightgrey, orange, yellow) and hex codes (with or without the leading #) both work.
Is my form data uploaded?+
No. URLs are built entirely in your browser. Only the final badge image request goes to shields.io when the preview renders.
