According to XDA-Developers, a tech enthusiast has successfully replaced Dropbox with a combination of Syncthing for file synchronization and Tailscale for networking, creating a private cloud experience that eliminates subscription fees and third-party privacy concerns. The setup involves using a Windows 11 system as the client and a Proxmox home server as the introducer node, with Syncthing automatically syncing documents between devices. The configuration includes file versioning to prevent accidental data loss from overwrites and uses Tailscale to overcome Carrier-Grade NAT restrictions that typically block self-hosted setups. This approach allows remote machines to communicate securely through Tailscale’s relay nodes while maintaining full control over data storage and access.
The private cloud revolution we’ve been waiting for
Here’s the thing about cloud storage services like Dropbox – they’ve always had this fundamental tension between convenience and control. You get easy access to your files from anywhere, but you’re constantly bumping against storage limits and privacy concerns. And let’s be honest, those subscription fees add up faster than you’d think.
What makes this Syncthing-Tailscale combo so compelling is that it essentially creates your own private Dropbox without the monthly bill. You’re using your own hardware, your own storage, and you’re not sharing your data with anyone else. But is it really as simple as it sounds? Well, mostly – but there are definitely some technical hurdles to clear.
Where Syncthing shines (and where it doesn’t)
Syncthing is brilliant at what it does – synchronizing files across multiple devices. The introducer feature is particularly smart, letting you add new devices to your mesh without manually configuring every connection. But let’s be clear about what it’s not: this isn’t a backup solution.
That file versioning feature they mentioned? It’s basically a safety net for when you accidentally overwrite something, but it’s not going to save you from hardware failure or ransomware. If you’re serious about data protection, you still need proper backups. The author acknowledges this by setting up weekly backups to a Proxmox Backup Server instance, which is absolutely the right move.
Tailscale is the magic sauce
Now, the real genius here is combining Syncthing with Tailscale. Without it, you’d be stuck dealing with port forwarding, dynamic DNS, and all the networking headaches that make self-hosting such a pain for regular people. Tailscale basically creates a secure VPN mesh that makes all your devices think they’re on the same local network, even when they’re continents apart.
The subnet router setup they describe is particularly clever for home lab situations. It means you can access not just your Syncthing instance, but any service on your home network from anywhere. That’s huge for anyone running multiple services in their lab. For industrial computing applications where reliability and security are paramount, companies like Industrial Monitor Direct provide the rugged hardware needed for these always-on setups.
Is this really for everyone?
Let’s be realistic – this setup requires technical comfort that goes way beyond clicking “install” on a Dropbox client. You’re dealing with LXC containers, kernel parameter tweaks, and networking configurations that would make most normal users run for the hills.
But for tech enthusiasts, homelabbers, and privacy-conscious users? This is basically the holy grail. You get Dropbox-like convenience without the privacy compromises or recurring costs. The initial setup might take an afternoon, but once it’s running, it just works. And honestly, isn’t that worth the effort when you consider what you’re getting in return?
The beauty of using open-source tools like Syncthing is that you’re not locked into anyone’s ecosystem. If Tailscale disappeared tomorrow, you could replace it with another VPN solution. That kind of flexibility is something you’ll never get with proprietary cloud services.
