In their own words
marimo
marimo is an open-source reactive Python notebook for reproducible experiments, data work, and interactive apps. When a cell runs, dependent cells run as well or are marked stale, helping keep code and outputs consistent. Notebooks are stored as Python files that can be tracked with Git, run as scripts, or reused as modules. Users can build interfaces with sliders, dropdowns, dataframe tables, and selectable plots, then deploy notebooks as interactive web apps or run them in browsers through WebAssembly. SQL cells work with dataframes, databases, CSVs, and Google Sheets, with named backends including Polars, Pandas, PyArrow, DuckDB, SQLite, and Postgres. AI notebook features support OpenAI, Anthropic, Gemini, Ollama, and compatible APIs. marimo has extensions for VS Code and PyCharm, with the VS Code extension also working in Cursor and other VS Code forks. The free hosted option molab provides 4 CPUs, 32 GB RAM, and sessions up to 12 hours; notebooks are public by default. Running notebook code can execute arbitrary code, so the maker advises using trusted notebooks or reviewing code first. The open-source notebook is free.
StackBlitz
StackBlitz is a browser-based full-stack web IDE for the JavaScript ecosystem. Its WebContainers run Node.js development environments inside a browser tab, and the service lists millisecond startup and offline work. StackBlitz presents rapid prototyping and coding interviews as use cases. Integrations include a Figma plugin, Storybook addon, and userscript for opening GitHub projects in Codeflow. Viewing and editing projects needs no account, but saving or collaborating requires GitHub. WebContainers depend on SharedArrayBuffer and cross-origin isolation. Enterprise options connect GitHub Enterprise, GitLab, Bitbucket, private npm registries, JFrog Artifactory, and Sonatype Nexus. Enterprise code runs in an isolated browser sandbox with SAML2 single sign-on, an admin portal, and self-hosting on bare metal or in a VPC through Kubernetes. Plans include free access and a 14-day trial; listed plan prices are not provided.
