As a social network developer, I've worked with some large and small companies as well as created some of my own networks. I've created everything from basic social networks for communities all the way to large networks for schools and global communities. For anyone looking to code their own network, it definitely requires knowledge of complex code, mainly HTML, MySQL, and PHP. If you don't have a background in these fields, Chameleon is a great alternative. Basically, Chameleon is an all-in-one solution that allows you to easily build moderate to advanced social networks. Chameleon itself is both a social network script (the code) and an easy to use admin panel (or backend). I've built sites with Chameleon and I actually prefer it for most types of projects over coding my own, as I can spring up sites a lot faster with Chameleon.
I've worked with both Chameleon and many other related social network scripts, and I can easily say that you get the most bang for your buck with Chameleon. You get a lot for a low price. One thing a lot of sellers do is sell you the basic script and charge you for modules. With Chameleon, you get eveyrthing in one payment. You also get access to all the code, which means you can modify it or hire someone to do it rather than having some of it locked up. Everything can be customized, including colors and wording. Updates occur about twice a month. You also get mobile apps with the package, rather than having to code your own. They also have decent support. Email is usually answered within hours and they also offer phone support.
Overall, if you're looking to build a social network, Chameleon is a great choice. It's easy to use and has everything you need. The only complain I have is you get only one domain per license. So if you want to use it on multiple domains, you have to buy another license. But it's already very cheap, so it only makes sense. If you plan on only developing a single site, then this is perfect for that reason, as you only have to purchase a single license for everything. You'll be able to make moderate to complex networks with this script. It's not for a simple site, as it's loaded with features. However, you can always edit the code or get a freelancer to do it for you. You can pretty much build sites similar to the leading social networks with Chameleon. Highly recommended.
Excellent script, Chameleon. Great for beginners or advanced users to make sites easily and readily. If you need help setting up a domain or logo, they also offer that for you as well. The script and service is geared towards beginners so it makes the whole process very user friendly. Try asking their support if you have any questions. You'll likely be impressed. Solid.
