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.
Replit
Replit is a software creation platform where users can describe applications in natural language and refine them with an AI agent. The agent works through chat, tests and revises code, and can use a browser to produce reports and address issues. Its cloud development environment supports coding and collaboration in a browser, with automatic package installation and built-in authentication, database, hosting, and monitoring. Replit supports websites, mobile projects, designs, slides, animations, data visualizations, 3D, games, documents, and spreadsheets, with more than 100 integrations. The free Starter plan includes daily usage, but limits publishing to one live project and running one background task at a time. Replit Core costs $18 per month billed annually, and Pro costs $90 per month billed annually. Pro supports up to 15 collaborators and 50 viewers, and includes database rollback for up to 28 days. Replit is available on Android, iOS, Linux, macOS, Windows, and web. Its mobile apps support building, sharing, and publishing web apps; native iOS development uses the web version with Expo Go previews.
