DataGrail vs ESLint
DataGrail
Cybersecurity
Privacy platform that finds shadow data systems and automates data subject requests across them
- From
- On request
- Free plan
- No
The short version
- Only ESLint has a free tier, so it costs nothing to try first.
- 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.; ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome

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.
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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.
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceDataGrail: Does it find systems we do not know about?
Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.
ESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceDataGrail: What does it cost?
Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.
ESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
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.
