GUI file synchronization client that can sync with any cloud provider

Help support Celeste

Hey! I'm Hunter Wittenborn, the creator and maintainer of Celeste.

I've had a blast working on Celeste in the time I've had available, but I'm currently not able to put all the time I'd like into it. I'm a university student which keeps me busy at times, but I also have part-time jobs on the side that keep me quite busy, even when I'm not occupied with my school work.

If you'd like to help me keep driving Celeste forward, I humbly ask that you consider sponsoring my work. With your help, I can use more of my time on Celeste's development, allowing it to flourish into a program that people everywhere can use!

Celeste

Celeste is a GUI file synchronization client that can connect to virtually any cloud provider.

• Backed by rclone, giving you a reliable and battle-tested way to sync your files anywhere
• Written with GTK4 and Libadwaita, giving Celeste a native look and feel on your desktop
• Written in Rust, making Celeste blazingly fast to use

Features

• Two-way sync
• Asking what to do when a local and remote file have both been updated since last sync
• Ability to exclude files/folders from sync
• Connecting to multiple cloud providers at the same time

Instructions still largely need to be written up - if you'd like to help with that, feel free to submit a PR!

Translating

Celeste uses Weblate to manage translations. See https://hosted.weblate.org/projects/celeste/celeste if you'd like to assist in translating.

celeste's Issues

Add S3 storage type

unwraps and panics instead of handling permission denied error

When selecting a folder that Celeste does not have permission to mount at (in my case /mnt/folder), Celeste crashes, and crashes again every time it's reopened with the following message:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }', celeste/src/launch.rs:416:134
stack backtrace:

Add Zoho Workdrive storage type

Add B2 storage type

Add Yandex Disk storage type

Localization support

It would be great if the app could be translated. I'll provide the Dutch translation once this is possible.

Add README.md and App Screenshots

Add SFTP storage type

Self signed certificate

please add support for the self signed certificate

Main thread panicks when reading local directory with trailing slash

After saving a folder pair with /home/flo/Dokumente/ as the local folder, the whole application crashed with the following error message:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', celeste/src/launch.rs:1594:34

When starting the application again, it crashes approximately half a second after the main window comes up, so I have no chance to interact with it.

The relevant source line:

celeste/celeste/src/launch.rs

Lines 1592 to 1594 in da2f913

	let local_path_stripped = local_path
	.strip_prefix(&format!("{}/", sync_dir.local_path))
	.unwrap();

I installed version v0.3.5 via Flatpak.

Add Proton Drive support

Nautilus Plugin

The official Nextcloud Client has a Nautilus plugin which integrates it a bit more (sharing in right click menu, emblems showing the sync state, ...)

Add Mega storage type

add dark mode tray icon for plasma desktop

icon color isn't right for plasma desktop.

Better appadata summary

The current summary "GUI file synchronization client that can sync with any cloud provider" could be better (too long, not a call to action, too many details).

I'd suggest something short and simple, e.g. "Sync your cloud files".

More general guidance here: https://gitlab.gnome.org/GNOME/Initiatives/-/wikis/App-Metadata

Nextcloud remote folder don't exist

Hello, is there any guide how to configure Nextcloud. How to enter path of remote folder?

Only sync when files are changed

Currently we sync by just looping forever and checking for changed. It would probably be better to just detect when a directory has been changed and then sync that directory.

Password isn't allowed to contain `:`

When trying to connect to a nextcloud account, celeste does not allow me to log in because it states that it cannot allow passwords with the char: :

My nextcloud provider allows passwords with :

Celeste is not verified by Google

Hello, I've been trying this app to sync files with google drive and so far, everything is good when sychronizing regular files. (There's a case when dealing with google docs, where Celeste duplicates the Google file into a corresponding Microsoft equivalent). But that aside, I just wanted to let you know that Google says that Celeste hasn't been verified, when trying to log in to google drive from the application, which might raise some red flags for less technical users.

I am hopefully attaching an image of that message by Google. Thank you for this marvelous work, though!

Add Snap installation method

Window gets larger as more errors start to pile up

The main window of celeste seems to get larger when there is a large list of Synchronization errors. 😿

Celeste can't complete sync when it's open and a file is updated in real time in the local directory (Google Drive)

I was testing the sync functionality when one is working with the files while Celeste is running in the background and I noticed some trouble. When I modify a file in the remote (Google Drive), Celeste is able to sync the corresponding file in the local directory without any problems. However, when modifying the file in the local directory, a sync error appears.

In this example, I opened a text file (test.txt) and added some more characters inside of it. Immediately, Celeste says that the file does not exist, even though they are still stored in the local and remote directories. The remote file was not updated because of said error. Also, when dismissing the error message, it appears again and again, causing Celeste to stop syncing that directory.

Hopefully, the screenshot helps. :)

Steps to reproduce:

1. Create a file in the local directory.
2. Open the file and edit its contents in the local directory.

Add pCloud storage type

Add tray icon

Consider using lzo compression for the snap package

Hello, I'd like to suggest that the snapcraft.yaml file includes the option to use lzo compression for the application. That way, the boot time for the application will be improved, compared to the default compression used.

Add Archlinux support

It will be great if someone make AUR package.

Regards.

Add ability to automatically start on login

It seems like celeste uses only 1 cpu core

It seems like celeste uses only 1 cpu core when working.

My laptop (CPU: intel 1255u) gets to 85 Celsius when celeste checks if there are any changes in my synced folder. Is this normal?

verify your app with Google.

Can you please verify your app with Google. So, that we don't get spooky warning.

There was an issue authenticating to Google Drive

It says rclone.conf was not found and tcp 127.0.0.1 was already in use.

Server Type - Google Drive (School Account)
Server Name - drive.google.com

Add kDrive (Infomaniak) storage type

I use kDrive as cloud provider. It would be nice to be able to use Celeste for synchronisation.

Support encrypting files before sending

Add a 'libadwaita' tag/topic in about section

It makes it easier to search apps made in libadwaita, by just going to libadwaita topic. Maybe add the libadwaita topic/tag in 'About' section in github?

Add SeaFile storage type

Support for MEGA cloud?

The MEGAsync desktop app kinda sucks. Is there an easy way to integrate MEGA into the app?

Celeste crashes when opened, if previously synced local folder not found

Celeste crashes when opened if the previously synced local folder is not found, for example removed or renamed.

Unknown error - thread 'main' panicked.

Everytime I try to sync Google Drive. I get the same error.

thread 'main' panicked at 'internal error: entered unreachable code', celeste/src/launch.rs:2226:33
stack backtrace:

And the app crash.

I get this log from terminal.

Unable to log in to Nextcloud

When trying to log in to Nextcloud, the app freezes and stops responding. Force quitting and relaunching the app, then typing in the same details again results in the app telling me that the server name already exists.

Add box.com support

Requested at https://www.reddit.com/r/linux/comments/10w725p/introducing_celeste_a_gui_file_synchronization/j7mzsyu?utm_medium=android_app&utm_source=share&context=3

Add pCloud storage type

It would be nice if you could also add compatibility with pCloud Storage. They have an API documented here and also some SDK's (no rust though, sadly).

Add ability to hide servers panel

The panel that shows the list of servers should have the ability to be hidden. Furthermore, when only one server is set up we should always hide it.

Add Flatpak installation method

Add AppImage installation method

add ability to restrict bandwidth

I have a rather slow connection. I use rclone in various custom/hacky ways to sync with gdrive, and I know there's an option to limit bandwidth.

It'd be great to see that added as a configurable parameter.

Add Google Drive storage type

Add Dropbox storage type

Add on-demand sync functionality.

The idea for this feature is inspired by the functionality offered by multiple cloud providers like pCloud and OneDrive in their native clients.

The aim is to display all files stored in these cloud platforms within the file manager without requiring them to be downloaded. Once accessed through opening and loading them with an application, the files will be synchronized in the background and stored locally. Ideally, there should also be the capability to always keep specific folders/files synchronized in case there is a desire to access them offline or in the event of poor internet connectivity.

The advantages are the ability to synchronize files to the cloud without having to visit the web interface or syncing a particular folder to the local storage initially, and ensuring that references to these files are not broken in the event that they are not intended to be kept on the computer constantly.

Add OneDrive storage type

Crash and error message after trying to delete folder connection

When removing a synced folder, app crashes with following error:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', celeste/src/launch.rs:1399:26

When trying to restart the app, this error appears:
