LimeSurvey
A self-hostable survey system with branching, multilingual forms, quotas, anonymous responses, exports, and plugins.
Why use it
Research teams can build concept tests, beta surveys, and community censuses while retaining deployment and raw-data control.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.
What to check
Complex surveys and self-hosted security need ownership, while cloud quotas and plugin licenses vary by plan.
