The record

Purpose: Nextjournal describes itself as a notebook for reproducible research and data-driven research.
Polyglot notebooks: A notebook can use multiple programming-language runtimes, with values exchanged between runtimes using files.
Collaboration: Users can edit notebooks together in real time and create public or private groups.
Versioning: Changes are saved automatically, including data and the full runtime environment, and previous changes can be restored.
Compute: The service provisions a compute instance for each running notebook and shuts it down automatically when computation is done.
GPU support: The homepage states support for up to 8 NVIDIA Tesla K80, P100, or P100 Workstation GPUs per runtime.
Integrations: Notebooks can access Amazon S3 and Google Cloud Storage, clone private GitHub repositories, and import images from Docker Hub.
Secrets: Secrets are stored outside notebooks and computational environments in Vault and can only be read by the user's profile.
Import and export: Nextjournal supports importing Jupyter, IPython, RMarkdown, and Markdown notebooks and exporting notebooks to Markdown.
Publishing: Published notebooks have permanent URLs and can be public or limited to group members; published versions are read-only and can be remixed by viewers.
Fair use limit: The free plan has no hard compute-time or resource limits, but Nextjournal reserves the right to cancel computation it deems excessive case by case.
Support: Enterprise priority support is provided through a team-to-team Slack channel, with responses within 24 hours during the week.
HIPAA: The pricing FAQ says HIPAA guideline compliance may be possible with the on-prem solution and gives AWS reference architecture as an example.
Audience: The homepage describes use cases for machine-learning researchers, data scientists, library authors, professors, and scientists.
