Based on my own experience and research, and the replies when I asked around what others use, I have listed suggested solutions below:
- A PHP library that enhances your website performance by optimizing the front end using techniques such as minifying, compression, caching, concatenation and embedding. All the work is done on the fly on demand.
- CSS Crush
- Concats and minifies CSS files.
- Django Static Management
- Django compressor
- YUI Compressor
- Google Closure Compiler
- YUI Compressor for .Net
- A .NET port of the Yahoo! UI Library’s YUI Compressor Java project.
- Packer for .NET
- Microsoft Ajax Minifier
- A tool to concatenate and compress CSS files.
Other tools or approaches?
Please let me know, by writing a comment, if you want to suggest other tools, so I can update this list and keep it as accurate and useful as possible!
