Awesome Badges

A curated collection of awesome things related to status badges.

While this list is maintained by Paul Melnikow from the Shields core team, it includes Shields-related and non-Shields-related resources.

Dynamic badge services

• Shields.io – Original home of the badges, launched in 2014.
• Badgen.net – Fast badge generating service launched in 2018.
• NodeICO – Large-format status badges for Node.js projects – which were once very popular!

Badge tools

• Badgie – Scans the contents of your repository and adds badges based on what it finds.

• Projectz – Render Badges into your README based on your package.json configuration

Raster badges

SVG badges are encouraged because they render better on Retina displays and scale up beautifully. However in a few environments, such as Slack and HTML email, SVG images won't render, so PNG badges are preferred. Shields offers raster badges through its raster server, raster.shields.io.

• svg-to-image-proxy – Rasterizing proxy based on Node and Puppeteer which can be hosted on Vercel. (Since 2019 this code has been used to run raster.shields.io, however it's about to be deprecated in favor of squint.)
• squint – Rasterizing proxy based on Rust and libcairo.

Static badges

• For The Badge – Provides static badges using a flat and boxy badge design which has become a classic. (This badge format is available as ?style=for-the-badge on Shields.io.)

Static badge collections
