The short version

  • Only IBM SPSS has a free tier, so it costs nothing to try first.
  • Each has a real cost: IBM SPSS add-on packages are priced separately from the base subscription, and the promotional 45% discount on them excludes renewals; REDCap a for-profit company cannot hold a licence or self-host REDCap, so a biotech or CRO that liked it at university simply cannot deploy it the same way and must buy a commercially licensed hosted version instead.
  • They diverge on capability: IBM SPSS covers Statistical analysis, REDCap covers Form and survey designer.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

IBM SPSS

  • Statistical testing and regression analysis for academic and market researchnot REDCap
  • Predictive modelling and forecasting without writing codenot REDCap

REDCap

  • An academic research group at an institution that already runs REDCap, where a new study database costs nothing beyond the time to build itnot IBM SPSS
  • A hospital collecting patient reported outcomes where data must stay on institutional infrastructure rather than a vendor cloudnot IBM SPSS
  • An investigator initiated trial that needs randomisation, an audit trail and statistical export without a commercial EDC budgetnot IBM SPSS
  • A multi site academic collaboration where each site can be given scoped access to a single longitudinal projectnot IBM SPSS

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

IBM SPSS

  • Add-on packages are priced separately from the base subscription, and the promotional 45% discount on them excludes renewals
  • Subscription cost renews at the then current price at the end of the first year, so the advertised rate applies to the first term only
  • Prices shown are described by IBM as indicative, vary by country and exclude applicable taxes and duties
  • Extended access periods of 12 months or more are handled as tailored pricing rather than a published rate
  • Advanced statistics, custom tables, decision trees and forecasting are separate add-ons rather than part of the base product

REDCap

  • A for-profit company cannot hold a licence or self-host REDCap, so a biotech or CRO that liked it at university simply cannot deploy it the same way and must buy a commercially licensed hosted version instead.
  • Because each institution hosts its own instance, support, uptime, backup and version currency vary by university, and a researcher has no recourse to Vanderbilt when the local instance is two years out of date.
  • It is free of licence fee but not free of cost: the hosting institution carries server, security, patching and support staffing, which is why some institutions charge internal recharges per project.
  • Validation for regulated use is the deploying institution responsibility, so an instance is not Part 11 compliant simply because REDCap supports the features; someone locally has to produce and maintain the evidence.
  • The interface and reporting are dated compared with commercial survey and EDC tools, and complex logic is built through data dictionary spreadsheets rather than a modern visual builder, which slows non technical study teams.

Answered from the vendors’ own pages

REDCap: Is REDCap really free?

The licence is free to non-profit institutions and government organisations that join the consortium, but they must host and support it themselves, so there is real internal cost.

REDCap: Can my company use REDCap?

Not by holding a licence or self-hosting. For-profit organisations must use a separately licensed commercial hosted route.

REDCap: Is REDCap 21 CFR Part 11 compliant?

It has the features to support Part 11 use, but compliance depends on how the hosting institution configures, validates and documents its own instance.

REDCap: Who supports it?

Your local institutional REDCap administrator, not Vanderbilt. Support quality varies by site.
