Internxt

Very. Internxt uses zero-knowledge, client-side encryption on everything — files are encrypted and split into fragments before they ever leave your device — and its apps are fully open source, so anyone can audit the code on GitHub rather than taking the company's word for it. That verifiability is its core pitch. The main consideration is scale, not security: it's a younger, smaller company than the established leaders, so it has a shorter operating history. On the cryptography itself, though, its model is among the more transparent in this comparison.

Private file storage and sync for people who want privacy they can actually verify. Everything is encrypted on your device, the apps are open source, and the company operates under EU privacy law (GDPR). Think of it as the open-source, privacy-first alternative to Big Tech clouds like Google Drive or Dropbox: the same core job of keeping your files synced and shareable across devices, but built so that reading your data simply isn't possible for the provider.

Yes — and the point is that you don't have to take it on trust. The architecture makes reading your files impossible for Internxt: zero-knowledge encryption with keys only you hold, all verifiable in the open-source code on GitHub. Privacy here is structural rather than a policy promise you're asked to believe. The trade-off, as with any encrypted service, is that losing your credentials means losing access — nobody can recover them for you.

Internxt sits among the cheaper privacy-first options. The Essential plan (1 TB) is listed at US$9.99/mo, and the company runs frequent promotions that cut the first-year price well below the standard rate. There's also a small free tier so you can start without paying at all, plus lifetime deals that swap the subscription for a one-time payment. If you value open-source privacy but don't want to pay a premium for it, the pricing is one of its strongest cards.

Internxt Universal Technologies — an independent Spanish company founded in 2017 by Fran Villalba Segarra. It's venture-backed but not owned by any tech giant. And because the software is open source, its privacy claims don't actually depend on trusting the owner at all: you can verify them in the code, which is rather the whole point of the project.

Valencia, Spain, where the development is done in-house, operating under EU privacy law (GDPR). For UK users after Brexit, EU jurisdiction still means strong data-protection standards, and the UK's data-adequacy arrangement with the EU keeps transfers straightforward. Combined with open-source, on-device encryption, the location is a privacy asset rather than any kind of drawback.
