In their own words
JupyterLab
JupyterLab is a web-based environment for interactive work with notebooks, code and data. Its workspace brings notebooks, text editors, terminals and custom components together in tabs and splitters. Code consoles act as scratchpads, and kernel-backed documents can run code in files such as Markdown, Python, R and LaTeX. It supports the .ipynb format used by classic Jupyter Notebook, and can view and edit formats including Markdown, images, CSV, JSON, HTML, LaTeX and PDF. Visualization libraries include matplotlib and Plotly; interactive plots or widgets may require additional packages. Extensions can add themes, viewers, editors, output renderers and interface controls, but can execute code in the browser, server and kernel, so only trusted extensions are advised. Real-time collaboration can be enabled with jupyter_collaboration. JavaScript and HTML outputs from notebooks created elsewhere remain hidden until the notebook is trusted. JupyterLab is free, open-source software under a modified BSD license, installed with pip or via a Homebrew command for macOS and Linux. It runs on Linux, macOS, the web and self-hosted systems.
Theia IDE
Theia IDE is an open-source, AI-native development environment for cloud and desktop, built on the Theia Platform. Users can select cloud, self-hosted or local AI models and create custom agents. It integrates official SDKs for providers including OpenAI, Anthropic and Google, and sends AI data to the provider the user chooses. The IDE supports VS Code extensions through Open VSX, though some Microsoft-proprietary extensions are unavailable and some extension API features may not work as expected. Language support uses the Language Server Protocol, including for Python, Java, JavaScript and C++. Workspace Trust puts untrusted folders in Restricted Mode and disables features that could execute code or read sensitive workspace content, but the project says this protection is still maturing. The IDE does not collect or transmit user activity, project details or code, though it can check for IDE and extension updates. The ready-to-use IDE is free at free. Its online demo is limited to 30 minutes per session. The modular Theia Platform can be used to build customized or white-labeled cloud and desktop IDEs and tools.
