Open source Web development tools have come a long way. The open source community offers a huge array of applications that are useful to Web developers and designers. In many cases, these open source tools are even more widely used than their closed source counterparts. And some open source Web tools don't even have any real closed source competitors.
As these tools mature, it's becoming more and more difficult to sort them into categories. Some blogging platforms are robust enough to build an entire site. Content management systems often have some features you usually find in Web app development frameworks, and text editors begin to look more and more like full integrated development environments (IDEs).
While that makes it tougher to organize our lists, it's good news for designers and developers. As Web tools offer more features, it makes Web professionals' jobs easier, and it opens up new opportunities for hobbyist and home users whose coding skills might not be as well developed.
Here are 56 of the best open source Web development and design tools that provide good alternatives to popular commercial, closed source software.
