The short version

  • Only Prettier has a free tier, so it costs nothing to try first.
  • Each has a real cost: Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults; 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.
  • 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.

Prettier

  • Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
  • Developers must format entire files rather than selective line ranges in some contexts
  • Limited language support compared to some alternatives, though it covers major languages

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catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.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.

Nymity Research, a maintained regulatory intelligence library acquired in 2019, and the TRUSTe third-party certification and seal programme.

Prettier: Can Prettier be integrated with ESLint?

Yes, Prettier integrates with ESLint by disabling ESLint formatting rules via eslint-config-prettier, allowing both tools to work together with Prettier handling formatting and ESLint handling code quality.

Not published. Reported enterprise agreements range widely depending on modules and organisation size, and certification services are quoted on top of the platform subscription.

Prettier: Does Prettier support configuration customization?

Yes. TrustArc is the renamed TRUSTe business and still operates the TRUSTe certification programme as a subsidiary.

TrustArc: Does it handle cookie consent for Europe?

Yes, it includes a consent manager with scanning and banner delivery, though pure-play consent vendors are cheaper if that is all you need.
