- Pricing for Nextcloud, Dropbox, and ownCloud was independently verified (August 21, 2026), matching Syncthing's own verification date; Google Drive's business/team pricing carries no verification timestamp in our listing data.
- Two of the four alternatives, Nextcloud and ownCloud, can be self-hosted for free with no user limit on their Community editions, keeping data off a third-party server the way Syncthing does; Dropbox and Google Drive are cloud-only, with free tiers capped at 2GB and a shared 15GB respectively.
- Review volume differs by orders of magnitude: Google Drive's 4.8/5 rests on 28,587 Capterra reviews and Dropbox's 4.5/5 on 21,704, both far larger samples than Nextcloud's 443, ownCloud's 60, and Syncthing's own 5/5 from just 1 Capterra review.
- None of the four alternatives replicate Syncthing's core architecture: all four route synced files through a company-operated server rather than transferring them directly between a user's own devices.

Syncthing alternatives at a glance
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| Syncthingreference | privacy-conscious individuals and self-hosters who want continuous file sync across their own devices without routing data through a third-party cloud server | True peer-to-peer synchronization with no central server: files transfer directly between a user's own devices over an encrypted, authenticated connection, so no third party ever holds a copy. | There is no official iOS client because Apple's platform restrictions limit background sync behavior the way Syncthing's protocol needs, and setup across multiple machines requires more manual configuration (adding devices, sharing folders, handling network discovery) than a plug-and-play cloud service like Dropbox. | Moderate | Free |
| Nextcloud | organizations that want a self-hosted, data-sovereign alternative to Google Workspace or Microsoft 365 for file sync, groupware, and video conferencing | A full collaboration suite (files, Talk conferencing, groupware, LibreOffice-based document editing, workflow automation) that self-hosts as one open-source codebase instead of stitching together separate tools. | Enterprise pricing requires a 100-user minimum to get a published rate, so smaller organizations wanting official support and SLA guarantees have to contact sales rather than see a self-serve price, and self-hosting the Community edition means the organization is responsible for its own updates, backups, and server maintenance. | Moderate | Free |
| Dropbox | individuals and teams who need dependable cross-device file sync and simple sharing links, especially teams already invoking Dropbox's large-file-transfer and version-history features | Selective sync and file-transfer links that handle files up to 250GB, combined with 175+ file-type previews and long version-history windows on paid plans. | Storage costs scale per user on team plans ($15-$24/user/month) rather than pooling cheaply, so growing teams or storage-heavy workflows (video, design assets) can see costs climb well past the advertised starting price, and reviewers note large-folder syncing can lag compared to lighter competitors. | Low | Free tier · paid from $9.99/mo |
| Google Drive | individuals and teams already using Google Docs, Sheets, and Slides who want real-time collaborative editing with simple cloud storage and sharing links | Native, real-time collaborative editing inside Google Docs, Sheets, and Slides directly from stored files, with no separate syncing step between storage and editing. | The 15GB free tier is shared across Drive, Gmail, and Google Photos rather than dedicated to file storage, so it fills up faster than competitors' storage-only free tiers, and some reviewers note bundled apps like Sheets feel feature-light compared to dedicated spreadsheet tools. | Low | Free tier · paid from $1.99/mo |
| ownCloud | organizations that need full control over where their files are stored (self-hosted or EU-hosted) and want an open-source alternative to Dropbox or Google Drive for file sync and sharing | Fully self-hostable file sync and collaboration with an open-source Community edition that has no user limit, plus a rewritten Infinite Scale (oCIS) architecture for real-time collaborative editing at scale. | Paid Standard and Enterprise editions require a 25-user minimum and custom quoted pricing with no published rate card, and the transition between the legacy ownCloud 10 codebase and the newer Infinite Scale architecture means some deployments run on an older, less actively developed base. | Moderate | Free |
Syncthing1.Nextcloud — best Syncthing alternative for organizations that want a self-hosted, data-sovereign alternative to Google Workspace or Microsoft 365 for file sync, groupware, and video conferencing
Nextcloud is the best Syncthing alternative for privacy-conscious users and organizations who want to keep full control of where their files live and are willing to run a central server rather than Syncthing's fully peer-to-peer, serverless model. Nextcloud's Community edition is free and open source under AGPL-3.0, self-hostable with no user limit, matching Syncthing's $0 price, but it bundles far more than file sync: Talk for video conferencing and chat, Calendar and Contacts groupware, and a LibreOffice-based Office app for real-time collaborative document editing, none of which Syncthing offers since Syncthing is a pure file-sync tool. Nextcloud holds a 4.6/5 rating from 443 Capterra reviews, a much larger sample than Syncthing's 5/5 from just 1 review. Paid Nextcloud enterprise tiers start around €71.29/user/year for organizations with 100 or more users that want SLA-backed support. Syncthing is still the better choice for anyone who specifically wants zero-server, direct device-to-device sync with no company able to see or store the data at any point: Nextcloud's Community edition still relies on a central server the organization must run and secure, unlike Syncthing's true peer-to-peer architecture where files transfer directly between devices with no server holding a copy.
Compared to Syncthing: full collaboration suite (Talk, groupware, document editing) vs pure file sync only, both free and open source but Nextcloud requires running a central server, 443 Capterra reviews vs Syncthing's single review
Wins:Bundles Talk video conferencing, groupware, and LibreOffice-based document editing alongside file sync, none of which Syncthing offers · 4.6/5 rating from 443 Capterra reviews, a far larger sample than Syncthing's 5/5 from just 1 review · Native apps across web, Windows, macOS, Linux, iOS, and Android, including iOS support Syncthing lacks officially
Loses:Still relies on a central server the organization must run and secure, unlike Syncthing's true peer-to-peer architecture where no server ever holds a copy of the data · Enterprise support pricing requires a 100-user minimum, with no published self-serve rate for smaller teams · The larger app ecosystem adds setup and configuration complexity beyond Syncthing's single-purpose file-sync focus
Pros
- Fully open source (AGPL-3.0) and free to self-host with no user limit on the Community edition.
- Bundles file sync, video conferencing, groupware, and document editing into one connected suite.
- Scales from a single Raspberry Pi to distributed installations serving tens of millions of users.
- Native apps across web, Windows, macOS, Linux, iOS, and Android.
Cons
- Enterprise support pricing starts at a 100-user minimum, with no published self-serve rate for smaller teams.
- Self-hosting the Community edition puts the burden of updates, backups, and uptime on the organization's own IT staff.
- Performance and app ecosystem depend heavily on the hosting hardware and configuration, unlike a fully managed SaaS suite.
- The large number of optional apps can make initial setup and configuration more complex than a single-purpose file-sync tool.
Pricing: Free — Free Community edition (self-hosted, no user limit), or enterprise tiers from €71.29/user/year (100+ users) vs Syncthing's entirely free, no-tier model (verified undefined NaN, NaN)
2.Dropbox — best Syncthing alternative for individuals and teams who need dependable cross-device file sync and simple sharing links, especially teams already invoking Dropbox's large-file-transfer and version-history features
Dropbox is the best Syncthing alternative for users who want simple, mature cross-device sync and sharing links without configuring peer-to-peer device pairing, trading Syncthing's serverless privacy model for convenience. Dropbox's free Basic plan includes 2GB of storage, and its Plus plan at $9.99/month raises that to 2TB with file transfers up to 50GB and 30-day file restoration, features Syncthing's pure sync tool doesn't offer since Syncthing has no built-in cloud backup at all. Dropbox holds a 4.5/5 rating from 21,704 Capterra reviews, an enormous sample compared to Syncthing's 5/5 from just 1 review, and supports over 700 million registered users with deep third-party integrations across Slack, Zoom, Adobe, and Microsoft Office. Syncthing is clearly the better choice for anyone who doesn't want a company holding a copy of their files: Dropbox stores every synced file on its own servers, the opposite of Syncthing's peer-to-peer model where files transfer directly between a user's own devices with no third party ever holding a copy, and Dropbox's team pricing at $15-24/user/month can climb well past Syncthing's permanently free, unlimited-device model.
Compared to Syncthing: built-in cloud backup and a 700M-user ecosystem vs Syncthing's pure P2P sync with no cloud storage, 21,704 Capterra reviews vs 1, but every file passes through Dropbox's own servers
Wins:Free Basic and $9.99/month Plus plans include built-in cloud backup, 30-day file restoration, and file-transfer links up to 50GB, none of which Syncthing offers · 4.5/5 rating from 21,704 Capterra reviews, an enormous sample compared to Syncthing's 5/5 from just 1 review · 700 million registered users and deep third-party integrations (Slack, Zoom, Adobe, Microsoft Office)
Loses:Every synced file is stored on Dropbox's own servers, the opposite of Syncthing's peer-to-peer model where no third party ever holds a copy · Team pricing runs $15-24/user/month, well above Syncthing's permanently free, unlimited-device model · Free tier is capped at just 2GB, far more limited than Syncthing's unlimited local storage across a user's own devices
Pros
- Reliable cross-device sync with a simple, well-understood synced-folder model.
- File-transfer links support very large files (up to 250GB) without needing a separate tool.
- Long version history and file-recovery windows on paid tiers protect against accidental deletion or ransomware.
- Broad platform support and deep third-party integrations (Slack, Zoom, Adobe, Microsoft Office).
Cons
- Per-user team pricing ($15-$24/month) makes larger teams considerably more expensive than storage-only competitors.
- Free tier is limited to just 2GB, among the smallest of major cloud storage services.
- Syncing very large folders can be slower than expected, according to reviewer feedback.
- Advanced security and admin features (SSO, tiered admin) are locked behind the higher Advanced tier.
Pricing: Free tier · paid from $9.99/mo — Free Basic (2GB), or Plus at $9.99/month (2TB) up to Advanced at $24/user/month (15TB pooled) vs Syncthing's entirely free, no-tier model (verified undefined NaN, NaN)
3.Google Drive — best Syncthing alternative for individuals and teams already using Google Docs, Sheets, and Slides who want real-time collaborative editing with simple cloud storage and sharing links
Google Drive is the best Syncthing alternative for people already using Google Docs, Sheets, and Slides who want cloud storage bundled directly with real-time collaborative editing, rather than Syncthing's standalone peer-to-peer file sync. Google Drive's free tier includes 15GB of storage shared across Drive, Gmail, and Google Photos, and additional storage through Google One starts at just $1.99/month for 100GB, scaling to $9.99/month for 2TB with family sharing for up to 5 members. Google Drive holds a 4.8/5 rating from 28,587 Capterra reviews, by far the largest review sample among Syncthing's listed alternatives, and offers full native apps across web, Windows, macOS, Linux, iOS, and Android, covering the iOS support Syncthing lacks officially. Syncthing is clearly the better choice for anyone who wants to avoid storing files on a third party's servers at all: Google Drive's 15GB free allotment is shared across three services and fills up quickly, and every file lives on Google's infrastructure rather than transferring directly between a user's own devices the way Syncthing's peer-to-peer model works, with no third party involved.
Compared to Syncthing: real-time Google Docs/Sheets/Slides collaboration vs Syncthing's pure file sync, 28,587 Capterra reviews vs 1, but files are stored on Google's servers rather than transferred directly between devices
Wins:Real-time collaborative editing built directly into Docs, Sheets, and Slides from stored files, a workflow Syncthing's pure sync tool doesn't offer · 4.8/5 rating from 28,587 Capterra reviews, by far the largest sample among Syncthing's listed alternatives · Google One storage plans start at just $1.99/month for 100GB, with native apps across web, Windows, macOS, Linux, iOS, and Android
Loses:Every file lives on Google's own infrastructure rather than transferring directly between a user's own devices, the opposite of Syncthing's peer-to-peer model · Free 15GB allotment is shared across Drive, Gmail, and Photos, so it fills up faster than Syncthing's unlimited local device storage · Business/team storage isn't sold standalone and requires a full Google Workspace subscription
Pros
- Real-time collaborative editing built directly into Docs, Sheets, and Slides from stored files.
- Google One storage plans are inexpensive relative to competitors, starting at $1.99/month for 100GB.
- Powerful in-document and in-file search across the entire Drive.
- 2TB plan allows sharing storage with up to 5 family members at no extra cost.
Cons
- Free 15GB storage is shared across Drive, Gmail, and Photos, so it fills up quickly with normal use.
- Some bundled apps (particularly Sheets) are described by reviewers as lacking features versus dedicated tools like Excel.
- Large file uploads can experience delays compared to some competitors.
- Business/team storage isn't sold standalone; it requires a full Google Workspace subscription.
Pricing: Free tier · paid from $1.99/mo — Free (15GB shared), then Google One from $1.99/month (100GB) up to $9.99/month (2TB) vs Syncthing's entirely free, no-tier model
4.ownCloud — best Syncthing alternative for organizations that need full control over where their files are stored (self-hosted or EU-hosted) and want an open-source alternative to Dropbox or Google Drive for file sync and sharing
ownCloud is the best Syncthing alternative for organizations that want a self-hosted or EU-hosted file sync platform with no user limit on the free tier, an option closer to Syncthing's own commitment to keeping data under the user's control. ownCloud's Community edition is free, open source, and self-hostable with unlimited users, matching Syncthing's $0 price, and its ownCloud.online option offers Germany-hosted managed SaaS for teams that don't want to run their own servers, with volume pricing starting around €1.85/user/year for large deployments. ownCloud holds a 4.3/5 rating from 60 Capterra reviews, a larger sample than Syncthing's 5/5 from just 1 review. Paid Standard and Enterprise editions require a 25-user minimum and custom-quoted pricing rather than a published self-serve rate. Syncthing is still the better choice for individuals who want the simplest possible privacy model: ownCloud's Community edition still routes files through a central server the organization must maintain and secure, while Syncthing transfers files directly between a user's own devices with no server, self-hosted or otherwise, ever holding a copy.
Compared to Syncthing: free, unlimited-user self-hosting plus a Germany-hosted SaaS option vs Syncthing's device-only peer-to-peer model, 60 Capterra reviews vs 1, but still relies on a central server
Wins:Community edition is free, open source, and self-hostable with no user limit, plus a managed Germany-hosted SaaS option (ownCloud.online) for teams that don't want to self-host · 4.3/5 rating from 60 Capterra reviews, a larger sample than Syncthing's 5/5 from just 1 review · Native apps across web, Windows, macOS, Linux, iOS, and Android, including iOS support Syncthing lacks officially
Loses:Still routes files through a central server the organization must maintain and secure, unlike Syncthing's fully serverless, direct device-to-device architecture · Paid Standard and Enterprise editions require a 25-user minimum and custom-quoted pricing with no published rate card · Two parallel architectures (legacy ownCloud 10 and newer Infinite Scale) can make choosing a deployment path more confusing than Syncthing's single, stable codebase
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.
Pricing: Free — Free Community edition (self-hosted, unlimited users), or ownCloud.online from ~€1.85/user/year (large deployments) vs Syncthing's entirely free, no-tier model (verified undefined NaN, NaN)

Frequently asked questions
Is there a free alternative to Syncthing?
- Yes, Nextcloud's Community edition and ownCloud's Community edition are both free to self-host, keeping data off third-party servers similar to Syncthing. Dropbox and Google Drive are also free at entry level, but both store data on their own cloud servers rather than staying peer-to-peer.
What is the closest alternative to Syncthing?
- No listed alternative fully replicates Syncthing's peer-to-peer, no-central-server model, but Nextcloud is the closest for privacy-focused users since its Community edition is free, open source, and self-hostable. It still relies on a central server the organization runs, rather than Syncthing's direct device-to-device sync.
Can Dropbox replace Syncthing?
- Dropbox can replace Syncthing for users who don't mind their files passing through Dropbox's cloud servers; it holds a 4.5/5 rating from 21,704 Capterra reviews and offers a free 2GB tier. It isn't peer-to-peer, so it requires trusting a third party with the data, unlike Syncthing.
Does Google Drive work on iOS unlike Syncthing?
- Yes, Google Drive has full native iOS and Android apps, unlike Syncthing, which has no official iOS client because Apple's background-execution restrictions limit the continuous peer-to-peer sync Syncthing's protocol needs. Google Drive's free tier also includes 15GB of storage shared across Drive, Gmail, and Photos.
Is ownCloud free like Syncthing?
- Yes, ownCloud's Community edition is free, open source, and self-hostable with no user limit, matching Syncthing's $0 price. Paid Standard and Enterprise editions require a 25-user minimum and custom-quoted pricing.
What's the best self-hosted alternative to Syncthing for teams?
- Nextcloud is the best self-hosted alternative for teams, bundling file sync with Talk video conferencing, groupware, and document editing in one free, self-hostable suite under AGPL-3.0. It holds a 4.6/5 rating from 443 Capterra reviews, though enterprise support pricing requires a 100-user minimum.
