LimeSurvey (formerly PHPSurveyor) is an open-source web-based survey application. Designed to be user-friendly, it enables users to develop and publish surveys, and collect responses, without doing any coding. While the software and rudimentary support is free, the developers use an optional donation system to help fund associated servers, support, and development.^[1]

Product history

LimeSurvey was registered as a SourceForge.net project called PHPSurveyor on February 20, 2003 and was originally written by the Australian software developer Jason Cleeland.^[2]^[3]

In 2004, during the 2004 U.S. presidential election, PHPSurveyor was used to gather data about voting irregularities. It identified over 13500 incidents in the first 10 hours of voting and was selected as part of their Election Incident Reporting System.^[4]

Starting in early 2005, Carsten Schmitz, a German IT project manager, started taking on some of the lead developer responsibilities, with the full project being transfered to him in 2006.^[5] On May 17, 2007 the project name was changed from PHPSurveyor to LimeSurvey in order to make software licensing easier by not including PHP in the name.^[6]

In 2009, LimeSurvey participated in the Google Summer of Code, a program encouraging students older than 18 years old to work on projects aimed at helping open-source projects. The student projects helped develop the interface and statistical modules of the upcoming LimeSurvey 2.0.^[7]. LimeSurvey once again participated in Google Summer of Code in 2010, with students developing a database storage engine for LimeSurvey 2.0, and implementing the much demanded "file upload question" type.^[8].
