Celeste

Celeste is a free, open-source graphical file synchronization client for Linux. It connects to multiple cloud providers at the same time and supports two-way synchronization. When a file changed locally and remotely since the previous sync, Celeste asks how to handle the conflict. Files and folders can be excluded from synchronization. Listed providers are Dropbox, Google Drive, Nextcloud, ownCloud, pCloud, Proton Drive and WebDAV. The project is backed by rclone and written in Rust with GTK4 and Libadwaita. Its project statement says no user data is collected, and the repository identifies GPL-3.0 as the license. The README lists Flatpak, Snap and Prebuilt-MPR installation methods, with Prebuilt-MPR described for Ubuntu 22.10 or later. Discord and Matrix rooms provide discussion and assistance, while bugs and feature requests go to the issue tracker. GitHub states that the repository was archived and made read-only on November 21, 2025. No mobile apps are listed.

Celeste offers straightforward multi-provider synchronization with conflict prompts and folder exclusions. Its archived, Linux-only status and lack of mobile apps are important constraints for future-focused or cross-platform setups.

Celeste suits Linux users who need desktop synchronization across several supported cloud providers. It is also relevant to users seeking free, open-source software without stated usage limits.
