Nextcloud vs Syncthing
Both are alternatives to Dropbox. Here's how they stack up — verified facts, no spin.
Also searched as Syncthing vs Nextcloud — same comparison, one verdict.
Syncthing keeps your data local by default and Nextcloud keeps it in the vendor's cloud — for most teams that single fact decides it.
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.
Syncthing
Continuous peer-to-peer file sync with no cloud.
Syncthing keeps folders in sync directly between your own devices, peer-to-peer and encrypted, with no server and no cloud in the middle. It is the purest self-owned option — brilliant for device-to-device sync, though it is sync only, not a sharing suite.
Side by side
10 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.
| Nextcloud | Syncthing | |
|---|---|---|
| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 90 | 92 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |
| Local-first data | No | Yes |
| License | AGPL-3.0 | MPL-2.0 |
| Pricing | Free / open-source (self-host); paid support/hosting optional | Free / open-source |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 4 GB | 512 MB |
| 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 | $0 if it runs on machines you already own; $6/mo for a small always-on VPS acting as the permanent peer |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 2 hours with Docker Compose, a weekend if you want it right | 20 minutes |
| 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. | Almost none. Occasional version bumps, and conflict files to clear when two devices edit offline. |
Nextcloud is Macrostack's recommended Dropbox alternative, so it's our pick here.

The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Nextcloud
if closest all-round Dropbox replacement.
Choose Syncthing
if your data should stay on machines you control, and no server or cloud at all.
Neither, yet
if both carry a real cost you should weigh first — you run and back up the server, and sync only — no web sharing/links. 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 Syncthing — common questions
Is Nextcloud a better fit than Syncthing for cloud storage & sync?
It depends on what you are optimising for, and the honest split is this: Syncthing scores 92 to Nextcloud's 90 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Nextcloud earns its place on a different axis — closest all-round Dropbox replacement. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Syncthing keeps its data local or in open formats, so leaving is an export rather than a negotiation. Nextcloud is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Nextcloud or Syncthing?
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 Syncthing 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.
