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; Very Good Security vGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.

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

Very Good Security

  • VGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • Token portability is the whole selling point yet leaving VGS means migrating tokens back out, a project the vendor has no incentive to streamline, so the lock-in you removed from your acquirer partly moves to VGS.
  • Entry pricing at around one thousand US dollars a month is real money for a pre-revenue fintech, and it buys volume-limited throughput, so cost scales with exactly the growth that made you buy it.
  • Scope reduction is not scope elimination: your QSA still assesses how you integrate, and teams regularly discover that a support tool or an internal admin screen pulled plaintext back in and dragged systems into scope again.
  • Proxy-based interception constrains how you design request flows, and non-standard payloads, streaming uploads or binary formats often need custom routing rules that make debugging production issues noticeably harder.

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.

Source
Very Good Security: Does VGS make me PCI compliant?

No. It removes cardholder data from your systems so your assessment covers a far smaller boundary, but you still complete an assessment and your integration is part of it.

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.

Source
Very Good Security: Can I move to another processor without re-collecting cards?

Yes, that is a core reason people buy it. The vault reveals stored credentials to whichever processor you route to.

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.

Source
Very Good Security: What does it cost?

Published entry pricing is about one thousand US dollars per month; growth and enterprise tiers are quoted.

Very Good Security: Is it only for card data?

No. The proxy handles any sensitive field, including bank details, national identifiers and documents, though payments is where the product is now focused.
