Summary

Nextjournal is a notebook for reproducible research and data-driven work, available as a hosted web service or for self-hosting. A notebook can combine multiple language runtimes, including Python, R, Julia, Clojure, Bash, JavaScript, and ClojureScript, passing values between runtimes through files. Teams can edit notebooks together in real time, and automatic versioning preserves changes along with data and the runtime environment so earlier states can be restored. Each running notebook receives a compute instance that shuts down when computation ends; GPU support is also listed. Notebooks can connect to Amazon S3 and Google Cloud Storage, clone private GitHub repositories, and import Docker Hub images. Import formats include Jupyter, IPython, RMarkdown, and Markdown, with Markdown export available. The free plan costs 0.00 USD per free, with limited concurrent compute resources and entry-level compute under a fair-use policy. Team starts at 299.00 USD per month, including five editors; Enterprise starts at 499.00 USD per month, also including five editors. A 14-day trial is listed.

Who it is for

Nextjournal is aimed at researchers, data scientists, library authors, professors, and scientists working with code and data. It also suits collaborators who need shared notebooks and saved runtime history.

What is good

Multiple language runtimes can share values through files
Real-time collaborative editing
Automatic history preserves data and runtime environment
Imports Jupyter, IPython, RMarkdown, and Markdown

What to know first

Free plan limits concurrent compute resources
Free computation is subject to fair use
Team starts at 299.00 USD per month

Verdict

Nextjournal combines collaborative notebooks with preserved environments and several runtime options. The free plan has compute constraints, while Team and Enterprise have substantial listed starting prices.
