CesiumCloud for Python

CesiumCloud cloud storage client for Python 3.10+.

Installation

Install the latest version from PyPI:

python -m pip install cesiumcloud

Or install the official wheel directly:

python3 -m pip install https://cloud.cesiummc.space/clients/cesiumcloud-0.1.3-py3-none-any.whl

Command-line use

python -m cesiumcloud authenticate
python -m cesiumcloud upload "/home/user/Documents"
python -m cesiumcloud upload "/home/user/dogimages.zip"
python -m cesiumcloud download "/home/user/Restored"
python -m cesiumcloud whoami

The cesiumcloud command is equivalent to python3 -m cesiumcloud.

Ubuntu 22.04, 24.04, 26.04 LTS and 26.10

Use Python 3.10 or newer. This Python client uses only the standard library and does not require Node.js.

On Ubuntu, use a virtual environment instead of changing the system Python:

sudo apt-get update
sudo apt-get install -y python3 python3-venv
python3 -m venv "$HOME/.local/share/cesiumcloud/venv"
"$HOME/.local/share/cesiumcloud/venv/bin/python" -m pip install --upgrade https://cloud.cesiummc.space/clients/cesiumcloud-0.1.3-py3-none-any.whl
"$HOME/.local/share/cesiumcloud/venv/bin/cesiumcloud" authenticate
"$HOME/.local/share/cesiumcloud/venv/bin/cesiumcloud" upload "$HOME/Videos/My video.mp4"

The CLI accepts a single path containing spaces even when it is unquoted, but quoting paths is still recommended. Authentication keeps the existing ~/.cesiumcloud/credentials.json.

Large uploads display transport-send progress in 256 KiB increments. 99% means data has been handed to the transport but may await server response; 100% appears only after the storage server commits the upload. The Python client does not yet maintain resumable checkpoints across separate processes.

Python SDK

from cesiumcloud import CesiumCloudClient

client = CesiumCloudClient()
client.authenticate()
client.upload("/home/user/dogimages.zip")
files = client.list_files()
print([file["name"] for file in files])
client.download("/home/user/Restored")

Authentication uses your CesiumCloud account without copying an API key. The Python implementation requires no Node.js runtime or third-party Python dependencies.

Current limitations

Data is streamed directly from local files. The Python client does not yet maintain restart-safe checkpoints across processes. Existing destination files are not silently overwritten. Keep an independent backup of important data.

Access management

Revoke credentials from the CesiumCloud dashboard. The logout command removes local credentials only.

Existing accounts

CesiumCloud connects to the existing API and stores credentials in ~/.cesiumcloud/credentials.json. Existing CesiumCloud package installations are not modified.
