Cybersecurity
Identity and business verification against national data sources in nearly 200 countries
- 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: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; Trulioo per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Trulioo
- Per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.
- Coverage breadth is real but depth is uneven; a country on the map may be served by one thin source with low match rates, which you only discover in a live test.
- You are charged per query including no-match results, so a market with poor source coverage burns budget producing nothing usable.
- Because it aggregates third-party data, data residency and consent handling depend on the underlying provider terms, which complicates GDPR assessments in some jurisdictions.
- Document and biometric capability is competent but not the strongest in the market, so buyers whose primary need is document fraud detection usually pair it with a specialist.

Answered from the vendors’ own pages
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.
SourceTrulioo: Does it need a document?
Not for the core product. Data-source matching uses name, address and date of birth, which is why completion rates are higher than document flows.
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.
SourceTrulioo: Are unmatched queries billed?
Yes, in general you pay per query rather than per successful match. Negotiate this explicitly if you are entering markets with thin coverage.
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.
SourceTrulioo: Can it verify companies as well as people?
Yes. Business verification including beneficial ownership is a distinct product line and a common reason to choose Trulioo over document-first vendors.
