Should I use ownCloud or Syncthing?

Use ownCloud if a team needs a central file server with web access, sharing and collaborative editing; use Syncthing if you want free, private sync between your own devices with no server at all.

Is ownCloud cheaper than Syncthing?

No — Syncthing is free with no paid tier, while ownCloud is free only in its self-hosted Community edition. ownCloud Standard and Enterprise require a 25-user minimum, annual billing and custom quotes.

Does Syncthing work on iPhone?

No — Syncthing has no official iOS app, because Apple's background-execution limits restrict continuous peer-to-peer sync, so iPhone users need unofficial third-party clients. ownCloud offers an iOS client.

Is ownCloud open source?

Partly — ownCloud's Community edition is free, open source and self-hosted with no user limit, while Standard and Enterprise are paid editions. Syncthing is fully open source under MPL-2.0.

ownCloud vs Syncthing (2026)

By Noahlast updated October 23, 2026

Verdict: Choose ownCloud if an organization needs a central file server with web access, sharing, real-time collaborative editing and apps including iOS, either self-hosted free with the Community edition or managed in Germany through ownCloud.online. Choose Syncthing if you want your own devices kept in sync with no server at all, free under MPL-2.0 with TLS and cryptographic device authentication. The deciding factor is architecture: ownCloud runs a server that stores and shares files for many users, while Syncthing copies files directly between your devices and has no iOS app or central backup.

ownCloud vs Syncthing pricing: which costs less?

Syncthing costs less: it is free with no paid tier, while ownCloud is free only in its self-hosted Community edition and its Standard and Enterprise editions need a 25-user minimum, an annual contract and a custom quote.

ownCloud publishes no rate card for Standard or Enterprise. ownCloud.online, the Germany-hosted SaaS, offers single-user plans with 500GB and team plans from 5 users with 1TB base storage plus 200GB per additional user, and volume or educational pricing starts around €1.85/user/year for large deployments. Self-hosted ownCloud also needs a server with ongoing maintenance and security patching, while Syncthing runs on the devices you already own. Kastelo Inc. sells optional Syncthing support contracts for organizations that want an SLA.

Is Syncthing more private than ownCloud?

Syncthing is more private by design, since files move directly between your own devices over TLS and no server ever holds a copy, while ownCloud stores files on a central server you host or on ownCloud.online in Germany.

Syncthing uses TLS with perfect forward secrecy and cryptographic device IDs, so no unauthenticated device can join a sync group. ownCloud's privacy pitch is control over where data lives: the Community edition runs on your own infrastructure, and paid editions add advanced security controls. The trade-off is redundancy: Syncthing has no built-in cloud backup, so losing all synced devices at once means losing the data.

Which is easier to set up, ownCloud or Syncthing?

Neither is plug-and-play: ownCloud and Syncthing both carry a moderate learning curve, with ownCloud requiring a server to run and patch and Syncthing requiring manual device pairing and folder sharing on every machine.

ownCloud ships two architectures, the legacy ownCloud 10 codebase and the rewritten Infinite Scale (oCIS), which can make choosing a deployment path confusing. ownCloud.online removes the server work for teams that accept Germany-hosted SaaS. Syncthing needs no server, but each device must be added and each folder shared by hand, and devices find each other on the local network or through UPnP or relay servers.

Can Syncthing replace ownCloud?

Syncthing can replace ownCloud for one person or a small group keeping their own devices in sync, but not for organizations that need a central file server, collaborative editing, iOS clients or managed hosting.

Syncthing covers continuous folder sync across Windows, macOS, Linux and Android at no cost. Syncthing has no central server, no hosted option and no official iOS app. ownCloud adds a web client, file sharing, real-time co-editing on Infinite Scale, apps for every major platform including iOS, and 9x5 or 12x5 support on paid editions. The two products overlap only on file sync: ownCloud is a server platform for teams, while Syncthing is direct sync between devices.

Strengths and weaknesses

ownCloud

Pros

Community edition is free, open source, and self-hostable with no user limit.
Full desktop and mobile client coverage: Windows, macOS, Linux, iOS, and Android.
ownCloud.online offers Germany-hosted SaaS for teams that don't want to self-host.
Infinite Scale (oCIS) architecture supports real-time collaborative document editing.

Cons

Standard and Enterprise pricing is not published; both require a 25-user minimum and a sales quote.
Support on the free Community edition is limited to community forums, with no SLA.
Two parallel architectures (legacy ownCloud 10 and newer Infinite Scale) can make choosing a deployment path confusing.
Self-hosting requires ongoing server maintenance and security patching that a fully managed cloud service doesn't.

Syncthing

Pros

Completely free and open source (MPL-2.0), with no paid tier or feature gating.
True peer-to-peer sync means no third-party server ever holds a copy of user files.
Strong security model: TLS with perfect forward secrecy and cryptographic device authentication.
Runs on Windows, macOS, Linux, and Android, manageable via a browser-based web GUI.

Cons

No official iOS app, since Apple's background-execution restrictions limit continuous peer-to-peer sync.
Initial setup across multiple machines requires manual device pairing and folder-sharing configuration.
No built-in cloud backup; since there's no central server, losing all synced devices simultaneously means losing the data.
No official mobile app for iOS means Apple users need third-party, unofficial clients if they want Syncthing on iPhone or iPad.

Which fits your use case?

Use case	Pick	Why
Individual syncing a laptop, desktop and Android phone privately	Syncthing	Syncthing syncs those devices directly over TLS for free, and no server ever holds a copy of the files.
Company of 50 that needs shared folders and collaborative editing	ownCloud	ownCloud provides a central server with file sharing and real-time co-editing, plus 9x5 or 12x5 support on Standard and Enterprise; Syncthing only syncs folders between paired devices.
EU team that wants managed file hosting	ownCloud	ownCloud.online is Germany-hosted SaaS with team plans from 5 users and 1TB base storage; Syncthing has no hosted service.
Household with iPhones and iPads	ownCloud	ownCloud lists iOS clients; Syncthing has no official iOS app and iPhone users need unofficial third-party clients.
Homelab user who wants no server to patch	Syncthing	Syncthing runs on existing devices with no central server, while self-hosted ownCloud needs ongoing maintenance and security patching.

Neither a match?

Both lists carry verified pricing and honest weaknesses for every option.
