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
Sumsub
- The published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests.
- You are billed per verification attempt in most configurations, meaning applicant drop-off and resubmissions cost money without producing a customer.
- Pass rates and document support vary noticeably by country, and a market that works well in Europe can produce materially worse rejection rates in parts of Africa and South East Asia.
- The AML screening tier bundles list coverage that large institutions would normally buy separately and tune, giving less control over match thresholds than a dedicated screening vendor.
- The company originated in Russia before restructuring to a UK entity, and some financial institutions still raise that history in vendor risk review, which can slow or block procurement at conservative banks.

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.
SourceSumsub: What does a verification actually cost?
1.35 USD on Basic and 1.85 USD on Compliance, but with 149 and 299 USD monthly minimums respectively. Below roughly 110 or 160 checks a month you are paying the minimum, not the rate.
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.
SourceSumsub: Do failed verifications get charged?
Attempts are generally billable, so a poor onboarding funnel raises your bill. Confirm the exact resubmission policy in your contract.
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.
SourceSumsub: Does it cover business verification?
Yes, KYB with company registry lookups and beneficial owner resolution is part of the platform rather than a separate product.
