Find out why users prefer BlockSurvey over REDCap
Frustrated with REDCap’s steep learning curve and outdated interface? BlockSurvey delivers a privacy-first, AI-powered experience with effortless design, zero-code survey building, and enterprise-grade security, without complexity.
Our Verdict
REDCap is free software for non-profit and academic research institutions once they join its consortium, but there's no self-serve signup — you need an institution's IT team to grant you access — and its dated interface, rigid field-type schema, and recent security disclosures make BlockSurvey the faster, more secure, sign-up-yourself choice for privacy-first survey collection.

Why Researchers Are Leaving REDCap
01
No self-serve access — you're dependent on an institutional REDCap admin or IT team just to get a project set up
02
Dated, less modern UI/UX with a steep learning curve and slow form-loading on larger projects
03 Rigid schema
changing a field type (e.g. true/false to multiple-choice) after data collection has started can corrupt or orphan existing data, and auto-generated internal field names make projects hard to read
04 Documented security incidents
3 disclosed XSS CVEs (2024-37394/37395/37396), a 2026 University of Nebraska Medical Center breach disclosure (unauthorized access from Sept 2023–Feb 2026 exposing names, DOB, MRNs and health data), and a China-linked (UNC6508) espionage campaign that compromised outdated internet-facing REDCap servers at North American medical research institutions
05
Structured project export (Data Dictionary/XML) only round-trips into another REDCap instance — it isn't a portable, cross-platform standard
06
Weaker modern integrations and advanced reporting/analytics compared to commercial survey platforms
