Celeste

What Celeste is

Celeste is a graphical file synchronization client for Linux that connects to cloud providers. It supports two-way synchronization and asks how to handle conflicts when a file has changed both locally and remotely since the last sync. You can exclude files and folders, and connect to several supported providers at once: Dropbox, Google Drive, Nextcloud, ownCloud, pCloud, Proton Drive, and WebDAV. The client is backed by rclone and built with Rust, GTK4, and Libadwaita. The project says it collects no user data and identifies its license as GPL-3.0. Its README lists Flatpak, Snap, and Prebuilt-MPR installation methods; Prebuilt-MPR is described for Ubuntu 22.10 or later. Discord and Matrix rooms are listed for discussion and help, with bugs and feature requests directed to the issue tracker. The repository is archived and read-only, and GitHub states it was archived on November 21, 2025. Celeste is free and open source, with no usage limits stated.

Who it suits

Celeste suits Linux users who want to sync files across multiple supported cloud providers and choose how to resolve sync conflicts. It has no mobile apps.

2. Choose a listed installation route: Flatpak, Snap or Prebuilt-MPR.
3. Use Prebuilt-MPR if installing on Ubuntu 22.10 or later.

Verdict

Celeste covers multi-provider, two-way file synchronization with exclusion and conflict-handling options. Its Linux-only availability and archived repository are important considerations.
