Syncthing is an open-source, continuous file synchronization program that lets users sync files between devices in real time without a central server. Its visual identity is maintained openly in the project’s GitHub repository, where the official logo assets are distributed alongside the source code.
Design and History
The current Syncthing mark is a circular emblem described by community developers as “the ring with three outer nodes linked to a central one,” a motif that visually echoes the project’s peer-to-peer synchronization model. The official vector file, logo-only.svg, is stored in the project’s assets directory and is also used as the scalable application icon in Linux distributions such as Debian. [1] [2]
The logo has undergone several revisions since the project’s early days. Commit history in the Syncthing repository shows logo-related changes dating back to February 2014, with updates in July and August 2014, March 2015, and a notable “Logo update” in June 2016. [3] A forum post from August 2014 confirms that a pull request updating the logo was merged around that time, replacing an earlier square “St” icon used on Android with the circular mark. [4]
In 2015, SVG versions of the logo were added to the repository, and a “Logo with text” variant was introduced alongside the standalone mark. [5] The project also maintains a horizontal logo variant (logo-horizontal.svg) for use in wider layouts. [6]
Meaning and Symbolism
The circular arrangement of nodes in the Syncthing logo is widely understood within the project community as a visual representation of the software’s decentralized architecture: a central node connected to three outer nodes, suggesting the peer-to-peer relationships that Syncthing establishes between devices. This reading is supported by the project’s own description of its functionality, which emphasizes that data is never stored on a central server and that every device is identified by its own cryptographic certificate. [7] [1]
The logo’s color palette uses a blue-to-cyan gradient. An SVG rendering of the mark in the Homelab icon set specifies gradient stops at #0882c8 and #26b6db, which matches the colors visible in the official asset. [8]
Typography and Design
Syncthing’s wordmark is included in the logo-horizontal.svg asset, which pairs the circular node mark with the project name in a horizontal lockup. [6] No official documentation identifies the specific typeface used in the wordmark, and the project does not publish a formal brand guideline document. The logo assets are distributed under the project’s open-source license and are freely available for use in packaging and third-party applications. [2]
