Onyxia

Onyxia is a powerful open-source web application designed to streamline the creation of state-of-the-art data science environments. Its core mission is to make advanced cloud-based resources accessible—even to users without prior expertise in cloud technologies. What distinguishes Onyxia is its intuitive, user-friendly interface that abstracts away the complexity of cloud infrastructure. Data scientists can effortlessly configure their preferred tools—such as Jupyter, RStudio, and VSCode—while selecting computational resources (GPU, CPU, RAM), defining environment variables, and setting up persistent storage. With just a few clicks, Onyxia automates the entire deployment process: it launches containerized environments, connects to S3-compatible storage systems, and manages secure credentials through integrations with Vault and OIDC providers. Importantly, Onyxia is not the environment where data analysis itself takes place. Instead, it acts as the gateway—a preparatory layer—where data professionals define and launch their technical stack before entering their actual workspace (e.g., Jupyter or RStudio). This separation of concerns keeps the experience streamlined and focused. A built-in file explorer facilitates the handling of large datasets, while Onyxia’s transparent architecture fosters learning and trust. Every action performed through the interface is logged in a terminal-style viewer, showing users the exact commands being executed (e.g., Helm, Kubernetes, Docker). This visibility not only promotes reproducibility and confidence but also serves as an educational bridge for those curious about the infrastructure powering their work. For deployment, Onyxia is installed by system administrators on a Kubernetes cluster—either on-premises or through a cloud provider—and exposed via a web UI for the data science team. Once in place, it dramatically reduces onboarding friction, encourages best practices, and empowers teams to focus entirely on data-driven innovation.
