What is LimeSurvey?

LimeSurvey, also known as PHPSurveyor (formerly known as PHPSurveyor), is an open-source online survey application or software. It lets its users develop, publish, accumulate and gather responses to surveys. Surveys also might include branching, custom preferred layout, and design (using a web template system) and can provide beginner-level statistical analysis of survey results. Surveys might be public or sometimes strictly managed using "once-only" tokens meant for only an individual survey participant.

On paper it sounds fine. So why are so many teams, including you, looking for an alternative? The sections below cover the main reasons.

Why teams are leaving LimeSurvey

Based on user reviews on G2 and Capterra, the main drawback of LimeSurvey is its complexity and steep learning curve. Some users have found the software difficult to use, with a dated, complex admin interface and confusing navigation. Some users have also reported bugs or technical issues, and several have commented that customer support can be slow to respond, which is frustrating when you need help fast. Beyond the review-site feedback, a few more concrete reasons keep coming up when teams evaluate a switch:

• Self-hosting is a maintenance job, not a feature. The open-source, self-hosted model that gives LimeSurvey its flexibility also shifts setup, patching, and uptime onto you or your developers, a real cost most small teams don't budget for.
• Security patching can't be an afterthought. In 2025, LimeSurvey disclosed a critical, unauthenticated remote-code-execution vulnerability from insecure deserialization (CVE-2025-56422, fixed in version 6.15.0+250623), alongside three additional critical CVEs (2025-41074/75/76). The vendor patched them, but any self-hosted instance left un-updated is exposed until an admin applies the fix manually.
• The UX is built for researchers, not respondents. LimeSurvey's front end is rigid and academic in feel rather than sleek or conversational, which is a weak fit for customer-facing or marketing surveys, and a big reason teams look at more polished tools instead.
• Paid tiers cap you fast. The Basic plan tops out at 1,000 responses/month and 250 MB of storage, which pushes any team with real response volume straight into the pricier annual Expert, Business, or Corporate tiers.

What is BlockSurvey?

BlockSurvey, is a survey platform built for people who care about privacy and security. If you want a reliable, secure way to create and manage surveys, forms, and questionnaires, BlockSurvey is designed for exactly that. Its main focus is user privacy.

It also comes with the features you need to build clear, engaging surveys. With customizable templates, advanced question types, and dynamic logic options, you can create personalized surveys tailored to your audience, and you can do it without giving up privacy or security.

Why BlockSurvey is a great alternative to LimeSurvey

Strong data privacy

BlockSurvey focuses on user privacy and data protection. Every response is encrypted end-to-end, and even we can't read it. Account and data ownership stays with you, not the platform provider, and the keys stay in your hands. This prevents data breaches, leaks, and the trust problems that follow them, which in turn increases response rates. LimeSurvey, by contrast, doesn't offer this level of built-in, by-default data privacy. Its privacy posture depends on how well you (or your host) secure and patch your own instance.

1000+ Templates

BlockSurvey has over a thousand free templates you can use to create surveys quickly. You can build anything from contact forms to online surveys using the pre-made templates without coming up with your own questions from scratch. They are all free, so when you need to put together a survey for anything, the templates are a fast starting point.

AI-Powered Surveys

Blocksurvey is the only online survey tool that uses AI to help create online surveys. When you need to make a survey but can't come up with the right questions, the AI can suggest questions based on your topic, which helps when you are stuck. Instead of writing everything yourself, you can let BlockSurvey draft the survey and get it done in less time.

Advanced Question Types and Logic

BlockSurvey offers a range of question types and advanced logic options, so you can create highly tailored surveys. With features like skip logic, branching, and piping, you can build dynamic, personalized surveys that keep respondents engaged.

Reliable customer support

BlockSurvey provides customer support so users get help when they need it. That includes detailed documentation and prompt, friendly support staff. LimeSurvey's customer support, by comparison, is community-driven on the free tier and has been flagged as slow by some reviewers on paid tiers, which makes BlockSurvey the more reliable choice when you need answers quickly.

Pricing and Affordability

BlockSurvey offers a competitive pricing structure with a free plan and paid plans built for teams that don't want to manage their own servers. Since plans and limits are updated from time to time, see our pricing page for the current numbers rather than relying on any figure quoted elsewhere.
