Syncthing: Secure, private file synchronization across devices
A brief introduction to the project:
Syncthing is an open-source file synchronization tool that enables secure, private synchronization of files across multiple devices. It allows users to share and access files between their devices without relying on third-party cloud services. Syncthing ensures that files are securely transferred and encrypted, providing a reliable and private solution for file synchronization.

Project Overview:
Syncthing aims to provide a decentralized file synchronization solution that allows users to sync files across multiple devices without relying on remote servers or cloud storage. Its primary goal is to provide a secure and private way to share and access files, ensuring that user data does not pass through any intermediate servers. This makes Syncthing an ideal choice for individuals or organizations that prioritize data privacy and control.
Syncthing addresses the need for secure and private file synchronization by eliminating the need for third-party cloud services. By synchronizing files directly between devices, users can ensure that their data remains in their control and is not vulnerable to data breaches or unauthorized access. The project offers a transparent and decentralized alternative to centralized cloud storage solutions.
Project Features:
Syncthing offers a wide range of features that contribute to its effectiveness as a file synchronization tool. Some of the key features include:
- Peer-to-peer synchronization: Syncthing works on a peer-to-peer model, where files are synchronized directly between devices without the need for intermediary servers. This ensures faster syncing times and eliminates the risk of data being intercepted by third parties.
- End-to-end encryption: All files transferred between devices are encrypted using strong cryptographic algorithms. This ensures that even if the data is intercepted, it remains private and secure.
- Cross-platform compatibility: Syncthing is compatible with a wide range of operating systems, including Windows, macOS, Linux, FreeBSD, and Android, allowing users to sync files across various devices seamlessly.
- Selective synchronization: Users have the flexibility to choose which folders or files they want to sync between devices, allowing for granular control over the synchronization process.
- Advanced versioning and conflict resolution: Syncthing keeps track of changes made to files and provides versioning capabilities, allowing users to roll back to previous versions if necessary. In case of conflicts, the tool provides robust conflict resolution mechanisms to ensure data integrity.
Technology Stack:
Syncthing is primarily built using the Go programming language, known for its efficient performance and scalability. It leverages the librsync library for efficient delta transfers and the BLAKE2 hash function for secure hashing. Syncthing also utilizes various open-source libraries and tools, including the Qt framework for the graphical user interface (GUI) on Windows, macOS, and Linux.
The choice of Go as the primary programming language offers several advantages, including its simplicity, concurrency capabilities, and cross-platform compatibility. It allows Syncthing to achieve high-performance file synchronization while ensuring a small memory footprint.
Project Structure and Architecture:
Syncthing follows a distributed architecture with a decentralized design principle. It consists of multiple components, including a GUI, a synchronization engine, and a discovery service.
The GUI provides a user-friendly interface for managing the synchronization process and configuring settings. It allows users to monitor the status of synchronization, add or remove devices, and control folder settings.
The synchronization engine is responsible for the actual file synchronization process. It uses a delta algorithm to transfer only the changed parts of a file, minimizing network bandwidth usage and improving overall performance.
The discovery service facilitates the discovery and connection of devices within the same local network or across the internet. It uses a distributed hash table (DHT) protocol to enable device discovery without relying on central servers.
Syncthing's architecture is designed to be modular and extensible, allowing developers to add new features or customize existing functionality easily.
