In their own words
Nextjournal
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.
Playcode
Playcode combines an AI builder for websites and apps with a cloud runtime for hosting full-stack projects. Describe a site or app in plain language, then edit it visually or work with its React, Vue, or HTML code. Playcode Cloud includes production hosting, a database, logins, files, background jobs, HTTPS, and WebSockets. It can restore code, files, and database together to a saved point in about a second. Projects can be downloaded as code and moved to another host; Playcode says users own their code. Its agent can build API integrations for services such as Stripe, email, Telegram, and WhatsApp when supplied with required keys. Playcode supports web, Android, iOS, Linux, macOS, and Windows, with real-time collaboration, public sharing, deployment support, and custom domains. The free plan costs nothing and allows three projects, one collaborator, and requires branding. Pro costs $25 a month; Max costs $100 a month. Automatic cross-machine scaling and multi-region failover are still on the roadmap.
