About
Syncthing is a continuous file synchronization program that syncs files between two or more computers in real-time. It replaces proprietary cloud services with an open, decentralized, and private solution. Files are synced directly between your devices using peer-to-peer connections, meaning your data never touches any cloud server. Features include end-to-end encryption, version control, ignore patterns, bandwidth limits, NAT traversal, file versioning, and a beautiful web UI. It's cross-platform (Windows, Mac, Linux, Android, BSD) and works great for keeping photos, documents, and important files in sync across your devices.
How to Self-Host Syncthing
Syncthing can be deployed with standard Docker Compose using the Yantr app catalog. This page collects the basic information searchers usually need first: what Syncthing does, which Docker image Yantr uses, default ports, dependencies, and where to find the original compose template.
If you searched for Syncthing Docker, Syncthing Docker Compose, or self-host Syncthing, this page is the direct landing page for that app in Yantr's catalog.
