You may have missed my previous comment. Here's what needs to be done:

Regular style: button height = 18 px, rx = 4, font y = 13, shadow y = 14
Flat style: button height = 20 px, rx = 3, font y = 14, shadow y = 15

It's probably better to have two Haml files for these styles, to keep things readable.

Few requests:

1. It looks like the text isn't correctly aligned yet, at least not on 200% zoom. The baseline of the number is like 1px too high:

To fix, change 'y' => '12', to 'y' => '13', on line 46 of the HAML.

2. Also, I'd be great to see a ?style=flat option, as seen on these buttons here:

3. A slight "text-shadow" would be nice too. Could be done like this:

<text x="45" y="15" fill="#010101" fill-opacity=".3">dependencies</text>
<text x="45" y="14">dependencies</text>

When trying to access svg, internal server error

Hi !
When I created the badges like this:
[![star this repo](http://githubbadges.com/star.svg?user=Yaoshicn&repo=awesome-music-for-programming&background=007ecg&color=bbb&style=flat)](https://github.com/Yaoshicn/awesome-music-for-programming)
It didn't work, just like

Move this project to my personal site http://ddavison.io to possibly prevent 500's.

Star & fork value numbers have gone missing!

thanks @silverwind

Badges are down

add an issues badge in addition to the stars and forks

It'd be ✨ super cool ✨ if you could choose custom background and text colors, e.g.

http://github-svg-buttons.herokuapp.com/star.svg?background=<HEX-COLOR>&color=<HEX-COLOR>&user=<USERNAME>&repo=<REPONAME>

ChangedenCZD changed to Chans-Open-Source, such as:
http://githubbadges.com/star.svg?user=ChangedenCZD&repo=vue-apis&background=007ecg&color=bbb&style=flat [Internal Server Error]
http://githubbadges.com/star.svg?user=Chans-Open-Source&repo=vue-apis&background=007ecg&color=bbb&style=flat

but this is OK:

I think it's safe to assume that GitHub's caching assumes a pretty long caching duration when no headers are present.

This cached content shows a 130 hour-long Age header, which I think is when the content will be re-requested. Following examples of other badges, they provide these cache headers, which pretty much disables any caching:

Cache-Control: no-cache, no-store, must-revalidate
Date: Sun, 24 Aug 2014 09:02:42 GMT
Expires: Sun, 24 Aug 2014 09:02:42 GMT
