The short version

  • Only MuckRock has a free tier, so it costs nothing to try first.
  • Each has a real cost: MuckRock muckRock's core platform, Squarelet identity service, and DocumentCloud are licensed AGPL-3.0, which requires anyone running a modified version as a network service to release their source code; TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • They diverge on capability: MuckRock covers FOIA Filing, TrustArc covers Nymity Research.
  • 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.

MuckRock

  • MuckRock's core platform, Squarelet identity service, and DocumentCloud are licensed AGPL-3.0, which requires anyone running a modified version as a network service to release their source code

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.
