Seafile vs Internxt

Both are alternatives to Dropbox. Here's how they stack up — verified facts, no spin.

Also searched as Internxt vs Seafile — same comparison, one verdict.

The short answer

Seafile can run on your own server and Internxt cannot — the choice is between operating it yourself and paying someone else to keep it up.

86

Seafile

Fast, reliable self-hosted file sync and share.

OPEN SOURCEAGPL-3.0SELF-HOST

Seafile is an open-source file-sync-and-share platform known for fast, reliable syncing and client-side encryption options. Its Community Edition is self-hostable and a strong choice when raw sync performance matters.

68

Internxt

Open-source, zero-knowledge encrypted storage with lifetime plans.

OPEN SOURCEAGPL-3.0

Internxt is an open-source, zero-knowledge cloud storage service — every file is end-to-end encrypted with AES-256 (and, since 2026, post-quantum Kyber), and the code is public on GitHub. It's a hosted service rather than something you self-host, so it sits between Nextcloud's full ownership and Dropbox's convenience: open, encrypted, EU-based storage with zero setup. There's a 10GB free tier and one-time lifetime plans if you'd rather not pay monthly.

The verdict

Seafile edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.

Weighing both against staying on Dropbox? Is Dropbox free? What it actually costs →

Seafile

Strengths

  • +Fast, reliable sync engine
  • +Client-side encryption option
  • +Mature clients

Trade-offs

  • −Some features are Pro-only
  • −Smaller app ecosystem than Nextcloud

Internxt

Strengths

  • +Open-source apps; zero-knowledge AES-256 plus post-quantum encryption
  • +EU-based (GDPR), privacy-first
  • +Free tier and one-time lifetime options

Trade-offs

  • −A hosted service — you don't self-host it
  • −Newer and smaller than Dropbox; fewer integrations
  • −Desktop sync less mature than the incumbents

Which one fits you

The trade-offs above, turned into a decision. Find the line that describes your team.

Choose Seafile

if you would rather run it on your own hardware, and fast, reliable sync engine.

Choose Internxt

if open-source apps; zero-knowledge AES-256 plus post-quantum encryption.

Neither, yet

if both carry a real cost you should weigh first — some features are Pro-only, and a hosted service — you don't self-host it. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.

What it takes to run these yourself

Real requirements and honest running costs, not the vendor quickstart.

Seafile vs Internxt — common questions

Is Seafile a better fit than Internxt for cloud storage & sync?

It depends on what you are optimising for, and the honest split is this: Seafile scores 86 to Internxt's 68 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Internxt earns its place on a different axis — open-source apps; zero-knowledge AES-256 plus post-quantum encryption. Neither is a wrong answer for every team; the table above is the actual comparison.

What happens if we want to switch later?

Neither of these is local-first by default, so plan the exit at the point you adopt rather than later. Export what matters on a schedule instead of trusting you can retrieve it on demand — that is the most common way a cloud storage & sync migration turns into a project instead of an afternoon.

Can I self-host Seafile?

Seafile can be self-hosted; Internxt cannot, so it stays on the vendor's infrastructure whatever you do.

Are Seafile and Internxt both alternatives to Dropbox?

Yes — both appear in our Dropbox comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Dropbox and now choosing between the two replacements, which is a narrower and much easier question.
