- Each has a real cost: DataGrail no pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.; Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
DataGrail
- No pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
- Automated fulfilment only works for systems with a supported connector, so homegrown applications and legacy databases still need manual handling, and those are usually where the awkward data lives.
- Discovery works by observing integrations and traffic patterns, so genuinely isolated systems, offline data and files on employee machines remain invisible and outside the data map.
- It is narrower than the enterprise privacy suites, lacking the assessment, third-party risk and wider GRC modules a large regulated organisation will also need, so it may be one of two platforms rather than the only one.
- Deletion automation is irreversible and mistakes are unrecoverable, so teams need real confidence in identity verification before enabling it, and that caution often keeps deletion semi-manual for months after purchase.
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

Answered from the vendors’ own pages
DataGrail: How is DataGrail different from OneTrust?
OneTrust orchestrates the workflow; DataGrail focuses on connecting to systems and completing the request, and benchmark data suggests it prices materially below OneTrust for comparable scope.
Prettier: Is Prettier free and open source?
Yes, Prettier is completely free and open source, available as an npm package with no licensing costs or subscriptions.
SourceDataGrail: Does it find systems we do not know about?
Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.
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.
SourceDataGrail: What does it cost?
Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.
Prettier: Does Prettier support configuration customization?
Prettier is intentionally opinionated with limited configuration options to enforce consistency. You can create a .prettierrc file for basic customization, but Prettier does not support extensive rule customization like ESLint.
SourceDataGrail: Does it cover consent as well as requests?
Yes, it includes consent management, though publishers needing certified advertising consent usually use a specialist CMP.
