Although the technology and philosophy behind the 'Deploy to Heroku' Button are quite awesome, the default look may not what you want. For one thing there is a distinct difference between the PNG and SVG versions Heroku has on offer.

Which means you have to choose between "looks good" and "Retina Ready".
Beyond that... the shape, form or size might break with the look and feel of your site or README file.
Or maybe, if you're a bit like me, you dislike the fact that you can't just use a service provider you already use for other services anyway.
Using a Shields.io button
As shield.io already offers a decent ammount of badges for various service providers, it might be nice to use the same style for your deploy button. The only real down-side is that the button will not contain the nice little icon. We could just use an "up arrow" instead.
Shields.io offers 3 flavours of styles you can choose from...
| Description | Image | URL |
|---|---|---|
| Standard |  |

| Flat (with rounded corners) |  |

| Flat and Square |  |
