Find out why users prefer BlockSurvey over LimeSurvey
Tired of a clunky interface and complicated customizations? BlockSurvey gives you a clean UI, AI-powered survey creation and analysis, and strong privacy. Own your data and get a smoother survey experience.
Our Verdict
BlockSurvey is the better pick if you want a modern, no-code survey builder with encryption that means even we can't read your responses, without the server upkeep that LimeSurvey's free self-hosted option demands. Choose LimeSurvey's Community Edition if deep branching logic and self-hosting for free matter more to you than turnkey privacy and ease of use.

Why Teams Are Leaving LimeSurvey
01
A dated, complex interface. G2 and Capterra reviewers consistently flag it as unintuitive and, at times, buggy compared to modern survey tools
02
The genuinely free option means self-hosting: you're responsible for installing, maintaining, and security-patching your own PHP/MySQL server
03
Recent vulnerability disclosures, an unauthenticated remote-code-execution flaw (CVE-2025-56422) and a related medium/high-severity cluster, were only patched in version 6.15.0, which left unpatched self-hosted instances exposed in the meantime
04 Cloud plan response caps are tight
as low as 25 responses/month on the free plan and around 1,000/month on the entry paid tier, pushing active users to upgrade quickly
05
Email and priority support are withheld entirely from the free Cloud plan
