The short version

  • Only Nix has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Nix the Nix language is lazy, dynamically typed and poorly documented, and its error messages frequently point at the wrong expression, so debugging a failing build is a skill that takes months rather than days to acquire.
  • They diverge on capability: ExpressVPN covers TrustedServer, Nix covers Content-addressed store.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

Nix

  • The Nix language is lazy, dynamically typed and poorly documented, and its error messages frequently point at the wrong expression, so debugging a failing build is a skill that takes months rather than days to acquire.
  • Flakes are the way essentially everyone uses Nix in 2026 and are still formally an experimental feature behind a flag, meaning tutorials, official documentation and real practice disagree with each other constantly.
  • Anything that expects a conventional Linux filesystem layout breaks: prebuilt binaries, language package managers that download their own toolchains, and proprietary vendor installers all need patching or an FHS-compatible wrapper.
  • Project governance has been publicly fractious, producing the Lix fork and the separately funded Determinate Systems distribution, so a new adopter now has to choose which Nix before they can start.
  • The /nix/store grows without bound until you garbage collect, and on a developer laptop with several pinned nixpkgs revisions it routinely reaches tens of gigabytes.

Answered from the vendors’ own pages

ExpressVPN: 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.

Nix: Do I have to run NixOS to use Nix?

No. The package manager runs fine on any Linux distribution and on macOS, and most teams start there with development shells rather than converting their servers.

ExpressVPN: 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.

Nix: Is Nix a replacement for Docker?

It solves an adjacent problem. Nix reproduces the contents of an environment exactly; Docker distributes an image. Many teams use Nix to build the image.

ExpressVPN: 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.

Nix: Are flakes safe to use in production?

They are used in production widely and are stable in practice, but they remain officially experimental, which means the interface can still change and documentation is split.

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.

Nix: What is Lix and should I care?

Lix is a community fork of the Nix implementation created after governance disputes. It is largely compatible; the practical impact is that you must decide which implementation your team standardises on.

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.
