Also searched as Seafile vs Nextcloud — same comparison, one verdict.
Nextcloud and Seafile are closely matched on ownership (90 vs 86) — this one comes down to pricing and to which trade-offs below you can live with.
Nextcloud
TOP PICKA full self-hosted cloud: files, sharing, and more.
Nextcloud is the most complete open-source Dropbox replacement — file sync and sharing plus calendars, contacts, and an app ecosystem — all on a server you control. It is the best all-round fit when you want Dropbox-style features without the cloud.
Seafile
Fast, reliable self-hosted file sync and share.
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.

| Nextcloud | Seafile | |
|---|---|---|
| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 90 | 86 |

| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 4 GB | 4 GB |
| Realistic running costWhat the box costs each month if you run it yourself. | $12–24/mo for a 5-user instance on a 4 GB VPS, plus object storage if the library outgrows the disk | $18–30/mo, against Dropbox Business per-seat pricing |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 2 hours with Docker Compose, a weekend if you want it right | 2 hours |
| Ongoing maintenanceThe part nobody budgets for. | Monthly app updates that occasionally break each other, database tuning as the file count grows, and PHP version bumps every major release. Budget an hour a month. | Moderate. Its garbage collector must be run periodically or deleted data never actually frees space. |
Nextcloud is Macrostack's recommended Dropbox alternative, so it's our pick here.

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Nextcloud
if a lower exit cost matters more to you than any single feature, and closest all-round Dropbox replacement.
Choose Seafile
if fast, reliable sync engine.
Neither, yet
if both carry a real cost you should weigh first — you run and back up the server, and some features are Pro-only. 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.
Nextcloud vs Seafile — common questions
Is Nextcloud a better fit than Seafile for cloud storage & sync?
It depends on what you are optimising for, and the honest split is this: Nextcloud scores 90 to Seafile's 86 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Seafile earns its place on a different axis — fast, reliable sync engine. 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 Nextcloud or Seafile?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Nextcloud and Seafile 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.
