JupyterLab vs Nextjournal

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.

Nextjournal is a notebook for reproducible research and data-driven work, available on the web or self-hosted. A notebook can combine programming-language runtimes, with values passed between them through files; listed languages include Python, R, Julia, Clojure, Bash, JavaScript, and ClojureScript. Users can edit together in real time and create public or private groups. Automatic saves preserve changes, data, and the runtime environment, with earlier versions available for restoration. Each running notebook gets a compute instance that shuts down when computation finishes, and a runtime can use up to 8 NVIDIA Tesla K80, P100, or P100 Workstation GPUs. Notebooks can access Amazon S3 and Google Cloud Storage, clone private GitHub repositories, and import Docker Hub images. Import formats include Jupyter, IPython, RMarkdown, and Markdown; notebooks can be exported to Markdown. Published notebooks have permanent URLs and can be public or group-limited; viewers can remix read-only published versions. Plans include Free and paid plans from $299/mo, with a 14-day trial.
