Arduino Cloud Editor vs Nextjournal

Arduino Cloud Editor lets users read, edit, and verify code for Arduino Cloud projects in a browser, including projects set up through Arduino Cloud. Its experimental AI Assistant helps write sketch code and is included across Cloud plans, with different monthly interaction limits. The Free plan costs nothing and includes two Things, five variables per Thing, 25 compilations per day, and 30 AI interactions per month. Annual plan prices listed are $72 a year for Maker, $1,000 a year for Team, and $20 a year for School; Enterprise has no listed price. Physical board connections on Windows, macOS, and Linux require the Arduino Cloud Agent. ChromeOS can create and upload sketches, though board support is limited to compatible boards. Arduino Cloud supports remote code uploads and dashboard sharing with viewer or editor access. Amazon Alexa voice control is available, and the School plan lists Google Classroom integration. Arduino says plan features are subject to fair-use limits, including caps on variables, sketch storage, and sketch files. Maker is intended for personal use; business and school users are directed to corresponding plans.

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.
