The short version

  • Each has a real cost: Formstack more expensive than form builders that only collect, which is the fair comparison for simple use; 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: Formstack covers Form builder, REDCap covers Form and survey designer.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Formstack

  • More expensive than form builders that only collect, which is the fair comparison for simple use
  • Document generation and signature sit in higher tiers, so the headline price is not the working price
  • The interface has accumulated features over a long life and shows it
  • Overkill where a form only needs to collect an answer

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currency vary by university, and a researcher has no recourse to Vanderbilt when the local instance is two years out of date.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

Formstack: What does Formstack cost?

It publishes tiered monthly pricing; document generation and e-signature sit in higher tiers, and HIPAA-capable plans are priced separately.

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.

Formstack: What makes it different from a plain form builder?

It generates documents from submissions and collects signatures on them, which is the step that otherwise involves retyping form data into a template.

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.

Formstack: Is it HIPAA compliant?

It offers HIPAA-capable plans for regulated data. That is a plan-level feature, not the default.

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.
