ESLint vs ExpressVPN
ExpressVPN
Cybersecurity
Consumer VPN registered in the British Virgin Islands, owned by Kape Technologies since 2021, with repeated third-party audits.
- From
- $6.67/month
- 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; ExpressVPN ownership passed in 2021 to Kape Technologies, formerly Crossrider, whose earlier browser extension platform was widely used to distribute adware, and Kape also owns VPN review publications, so nominally independent rankings a buyer consults may originate inside the same corporate group.

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
ExpressVPN
- Ownership passed in 2021 to Kape Technologies, formerly Crossrider, whose earlier browser extension platform was widely used to distribute adware, and Kape also owns VPN review publications, so nominally independent rankings a buyer consults may originate inside the same corporate group.
- In 2021 the company's then chief information officer was named in a United States Department of Justice deferred prosecution agreement over work for a foreign government's offensive cyber programme and remained in post, which is a governance fact that sits uncomfortably alongside a product sold entirely on trust.
- Audits are point-in-time engagements against an agreed scope, so they establish that specified servers and code matched the stated policy when examined, not that the infrastructure behaves the same way today or under different ownership.
- Several country locations are virtual, meaning the hardware physically sits elsewhere, and after India's 2022 directive requiring VPN providers to retain subscriber data ExpressVPN withdrew its Indian servers, so an Indian connection is routed through hardware in another country, which matters if you need genuine in-country routing.
- There is no port forwarding and no dedicated IP option, so seeding torrents, hosting a service behind the tunnel and any inbound connection do not work, and users who need those capabilities have to use a different provider.

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.
SourceExpressVPN: Who owns ExpressVPN?
Kape Technologies, which acquired it in 2021. Kape was previously named Crossrider and also owns CyberGhost, Private Internet Access and Zenmate, along with the review sites vpnMentor and Wizcase.
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.
SourceExpressVPN: Is the British Virgin Islands jurisdiction actually useful?
It has no mandatory data retention law and is outside the Five, Nine and Fourteen Eyes arrangements, which is the reason it was chosen. It also means limited practical legal recourse for a subscriber, so the jurisdiction protects the company's ability to hold no data rather than protecting you against the company.
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.
SourceExpressVPN: Has the no-logs claim been audited?
Yes, repeatedly. PwC and KPMG have examined the no-logging claims and the TrustedServer architecture, and Cure53 has reviewed the applications, extension and protocol. The reports are published.
ExpressVPN: Can I torrent with it?
Yes, peer-to-peer traffic is permitted on the network, but there is no port forwarding, so you can download but you cannot accept inbound connections and seeding performance suffers as a result.
ExpressVPN: Does it work in China or similar networks?
Sometimes, using obfuscated connection modes, but no provider can guarantee this and availability changes without warning. Treat it as best effort and have a fallback.
