NINJA-IDE vs Positron

NINJA-IDE is a free integrated development environment for creating applications, with tools for managing Python projects. The editor provides syntax highlighting, code completion, and help with imports and navigation. A code locator gives access to project files, functions, and classes, and documents can highlight static and PEP 8 errors. Users can manage files within the IDE, run a Python project or open file with one click, and render HTML files inside the application. Plugins can extend the editor and integrate functionality. The download page lists v2.4 installers for Windows 10/11 and Linux distributions; its macOS entry says the app is unavailable there and offers source code only. Listed requirements are Python 2.7 and PyQt 4.7 or later. The project describes the software as GPLv3+ and lists a mailing list and GitHub issues for questions and bug reports. The website says it is no longer run by the official authors.

Positron is a data science IDE for Python and R, available on Linux, macOS, and Windows. Its Data Explorer provides an interactive interface for exploring and manipulating large local or remote datasets. The IDE supports Jupyter notebooks and Quarto for reproducible reports and presentations, and includes a Connections pane for databases and a Catalog Explorer. Listed capabilities also include an integrated debugger, advanced code intelligence, remote development, and Python environment tools. Posit Assistant can draw context from a live Python or R session, including loaded data, plots, and console history. Positron's AI features use a bring-your-own-key model, with users or their organizations paying the selected model provider directly. Posit says it does not track, collect, or store prompts, code, or conversations entered through these features when an external provider is used. It does not support code written or generated in Positron, including AI-generated code. The desktop IDE is free. Publishing to Posit Connect requires a subscription; Positron Pro on Posit Workbench is listed for enterprise governance, scalable compute, SSO, and dedicated support.
