The short version

  • Only Zotero has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Zotero free account storage is limited; paid tiers start at $20/year for 2GB and reach $120/year for unlimited storage

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal 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.
  • 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currency vary by university, and a researcher has no recourse to Vanderbilt when the local instance is two years out of date.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.

Zotero

  • Free account storage is limited; paid tiers start at $20/year for 2GB and reach $120/year for unlimited storage
  • Sync and web access are optional add-ons layered on the core desktop app rather than included outright

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.

Zotero: How much storage does Zotero's free tier provide?

The free tier includes 300 MB of storage for research materials, citations, and related files. Collaboration features in group libraries are available at no additional cost.

Source
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.

Zotero: What are the pricing tiers for Zotero paid storage plans?

Zotero offers three paid storage tiers: 2 GB for $20 per year ($1.67 monthly), 6 GB for $60 per year ($5 monthly), and Unlimited storage for $120 per year ($10 monthly).

Source
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.

Zotero: Do group libraries count against storage limits in Zotero?

Group library file storage draws from the group owner's personal storage account, not a separate quota. Collaboration in group libraries is available at no additional charge.

Source
REDCap: Who supports it?

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