Why BlockSurvey is Your Perfect REDCap Alternative
Why Researchers Are Leaving REDCap
No self-serve access — you're dependent on an institutional REDCap admin or IT team just to get a project set up
Dated, less modern UI/UX with a steep learning curve and slow form-loading on larger projects
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
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2026 exposing names, DOB, MRNs and health data), and a China-linked (UNC6508) espionage campaign that compromised outdated internet-facing REDCap servers at North American medical research institutions
Structured project export (Data Dictionary/XML) only round-trips into another REDCap instance — it isn't a portable, cross-platform standard
Weaker modern integrations and advanced reporting/analytics compared to commercial survey platforms

- Modern, no-code drag-and-drop builder with AI-assisted survey creation and analysis
- Transparent pricing with a free plan, no sales quote required
