Free AJAX Library
Today, BackBase will release the free community version of their BackBase AJAX backend. If you’ve ever wanted to write AJAX enabled websites, this is your change. There are multiple demos online that are very good and offer loads of functionality, all client side!
It’s not online as I write this, but you can signup on the main page to be notified when it’s released. I just spoke to someone from BackBase and he said they’ll be uploading it any time now soon. They also have a .NET enabled version of their library, I don’t know if it’s included in this free community release though.
