- I highly recommend this library. It is built over Bootstrap core, and rtl support is added as it is a bootstrap theme. This would make your code more maintainable as you can always update your core bootstrap files. CDN
- Another option to use this stand-alone library: http://zerox.me/projects/bootstrap3/ It aslo comes with few awesome Arabic fonts. Github repository.
- Another suggestion this http://pyjamacoder.com/2012/02/01/twitter-bootstrap-v2-rtl-edition/
- This is pretty good for bootstrap 3 RTL support. http://www.eyadio.com/post/2013/08/29/Twitter-Boostrap-version-3-with-RTL-support
