Syncthing vs Nextcloud

Syncthing and Nextcloud both put your files in your own hands, but they are aimed at different jobs. Syncthing is a pure peer-to-peer sync engine: it keeps designated folders identical across your devices with no central server, no accounts, and no web portal. Nextcloud is an all-in-one file platform: a central server with a web interface, sharing links, and a 200+ app ecosystem covering calendar, contacts, and an office suite. One is a single-purpose tool; the other is a full platform. Both can be exactly right — depending on what you want out of your files.

The core difference: sync vs. the platform

Syncthing is built around one idea: keep folders in sync, device to device. Every machine runs a small Go daemon, and they reconcile changes directly with each other over encrypted connections — no server in the middle, no account system, no point of failure beyond your own devices. It's rated 2 / 5 to deploy, runs in 256 MB, and does its one job extremely well. There's a web UI for configuration, but it is not a file portal — you can't browse or share files from it the way you would from a cloud drive.

Nextcloud is the platform. The PHP server runs on a VPS with a database behind it (the default stack adds MariaDB), gives you a full web file browser with share links and password-protected sharing, and layers on calendar, contacts, a built-in office suite, and an app marketplace of 200+ add-ons. That breadth is why it's rated 3 / 5 to deploy and wants 1 GB of RAM — it's a server, not a daemon, and you operate it like one.

Privacy and control

Both are fully self-hostable and give you control over your data, but they architect that control differently. Syncthing's model means no server ever sees your files — they travel directly between your own devices — and there's nothing to host at all if you're happy with device-to-device sync. Nextcloud keeps everything on your server, which is great for a single source of truth and for sharing with people who aren't your devices, but it does mean all your data lives in one place you're responsible for backing up and securing.

Web access and sharing

If you need to reach your files from anywhere — a browser, a share link to a client, a public download — that's Nextcloud's territory. It's a proper web application with accounts, per-file sharing, and an ecosystem of desktop and mobile clients that sync against the server. Syncthing's apps sync the folders you configure and nothing more; there is deliberately no concept of "sharing a link to the internet."

Using them together

The two aren't mutually exclusive, and plenty of setups use both. A common pattern: Nextcloud as the central file platform with web access and collaboration, plus Syncthing running on the server and your devices to keep specific folders in sync instantly and privately. Syncthing can even point at Nextcloud's data directory, so the platform stays the source of truth while device-to-device sync rides on top.

Running either on a VPS

Neither needs much. Syncthing is dramatically lighter — 256 MB as a background daemon with no database — so it can sit on an existing server or a cheap VPS alongside anything else. Nextcloud wants 1 GB and a database, which still fits comfortably on the entry tier of any box in this guide. Pick your purpose first: pure sync means Syncthing; a file platform with web access means Nextcloud.

Pick Syncthing if…

• You want private device-to-device sync with no central server, no accounts, and no third party in the path.
• You need folder sync only — no web portal, no sharing links, no office suite — and want the lightest possible footprint.
• You'd rather not operate a server for the job.

Pick Nextcloud if…

• You want an all-in-one file platform — web access, share links, and a 200+ app ecosystem with calendar, contacts, and office editing.
• You want a central source of truth for your files, reachable from any browser or client.
• You're comfortable running a server with a database and backing it up.
