Ajaxian.com 2006 Survey Results

Ajaxian.com 2006 Survey Results

The results of our second annual Ajaxian.com survey, prepared by Richard Monson-Hafael from the Burton Group, are in. And the winner is… Prototype, the most popular Ajax framework, by a considerable margin: 43% of you use it. Script.aculo.us is next, at 33%, confirming observations that many of made of the popularity of that duo.

The full results of our framework survey follow:

Note that multiple responses per participant were allowed; we’ve also thrown out any result with less than 3% of responses in the above graphic.

We also asked you about the server-side platform you’re using. The big winner here was PHP, with 50% of you using it:

Some other interesting factoids:

• 25% of you eschew frameworks and work with XMLHttpRequest directly (wow!)
• 11% of you are using JSON to transfer data; unfortunately, we didn’t ask enough questions to determine how this compares with XML or other data formats
• 3% of you are still using Microsoft’s “classic” ASP framework; five of you (~0.6%) are using C++ (+2 points for increased performance, -100 for increased complexity?)
• 2% of you wrote in to say that you’re using Adobe’s Flex toolkit (hey, those banner ads are working out…); 2% also indicated that they use the Flex/Ajax bridge. Unfortunately, the survey software we used doesn’t let us correlate these entries, so we can only say that 2%-4% of you are using Flex in some way
• One participant uses Delphi (how’s that working out for you?), and another is using LISP (can we hire you?).
