My open source software
I've created several open source Limesurvey plugins. Feel free to download them, fork them, change them and use them in any way you want. Pull requests are welcomed, but please check the contribution guide first!
LimeRemote PHP Package
A package to use the Limesurvey Remote Control with PHP, and Laravel in particular. Currently it supports all default remote control actions, and any actions you have added using the Extended remote plugin.
LimeZap and Zest
LimeZap is a tool to connect your Limesurvey installation with Zapier. Using Zapier, you can connect to the huge number of services they support. For instance, you can create aa new row in a Google spreadsheet everytime someone submits a survey, or the other way around, create a new token everytime someone buys something in your webshop.
Zest is a tool to automate your Limesurvey instance. Easily schedule invites and reminders, copy and migrate surveys, add participants and create secure client pages.
