OpenAeroStruct is a lightweight tool that performs aerostructural optimization using OpenMDAO.

WireViz is a suite of tools for documenting electrical connections, converting wire gauges, and producing bills of materials and diagrams. It functions as a text-to-diagram framework that converts descriptions of cables and pinouts into graphical wiring harness diagrams and technical specifications. The system includes a wiring harness diagramming tool that generates SVG or PNG files from text descriptions and a wiring BOM generator that produces comprehensive bills of materials for cables and electrical harnesses. It also features an electrical wire gauge calculator for converting thickness

foxBMS is a free, open and flexible development environment to design battery management systems. It is the first modular open source BMS development platform.

FreeCAD is an open-source engineering design suite designed for parametric 3D modeling, architectural planning, and mechanical assembly. It functions as a professional-grade platform that utilizes history-based operations to allow for non-destructive design updates, enabling users to construct complex geometry through a sequence of constrained sketches and solid operations. The platform distinguishes itself through a highly modular, workbench-based architecture that allows users to tailor the interface and toolsets to specific engineering domains. It features deep Python integration, which se

Orange3 is a visual data mining platform that provides an interactive canvas for building data analysis workflows without writing code. At its core, it offers a widget-based visual programming environment where users connect configurable components to perform data preprocessing, machine learning model training, statistical evaluation, and interactive visualization. The platform is built on NumPy-backed data tables with domain descriptors that define variable names, types, and roles, and includes a lazy SQL query proxy for working with database tables without loading all data into memory.
