LimeSurvey (formerly PHPSurveyor) is a free and open source online statistical survey web app written in PHP using a MySQL, SQLite, PostgreSQL or MSSQL database, distributed under the GNU General Public License.
[2] Its web interface enables users to develop and publish online surveys, collect responses, review statistics, and export the resulting data to other applications.
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.
Students developed a Database Storage Engine for LimeSurvey 2.0, and implemented the much demanded “File upload question” type.
[11] In November, LimeSurvey also participated in the Google Code-in, a similar program rewarding high school students to contribute to open source projects.
The code base for LimeSurvey 2.0 was completely re-written from scratch using a MVC (Model–view–controller) approach and the Yii PHP framework.
Besides the structural code changes aimed at better modularity the new version also has a new GUI with a completely new design using AJAX technology.
In 2016 Version 2.50 was released by LimeSurvey GmbH which has a completely revamped administration user interface and fully responsive survey design templates.
As of October 2024, both the frontend and backend of LimeSurvey are available in 116 languages and dialects; 27 of these have at least 95% of the translations done (Catalan, Chinese, Czech, Dutch, Finnish, French, Galician, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Slovak, Spanish, Swedish, Thai, Turkish).
[15] LimeSurvey is used by the Austrian Vorarlberg State Government, Ars Electronica, and several open source organizations such as OpenOffice.org, Ubuntu, and GNOME.
[26] In December 2007, LimeSurvey won the first place Les Trophées du Libre award in the category Enterprise Management.
The Les Trophées du libre contest recognizes innovative and promising Open Source projects.
