FreeCAD / FreeCAD

Official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.

tangency-labs / fieldcraft

One open-source modeler for structures, heat and fluids, built from scratch in pure Rust: parametric part in, verified results out. Automatic all-hex and tet meshing, our own nonlinear implicit and explicit FEA, heat transfer and lattice Boltzmann CFD — every result checked against theory. For engineers and AI agents alike. Free, forever.

bpmn-io / bpmn-js

A BPMN 2.0 rendering toolkit and web modeler.

zmodelerlover / OpenNR-Installer

Finds your games, fetches and verifies the payloads, installs ReShade and the DLSS-NR add-on

sdatkinson / NeuralAmpModelerCore

Core DSP library for NAM plugins

nullptrlabs / pgmodeler

Open-source data modeling tool designed for PostgreSQL. No more typing DDL commands. Let pgModeler do the work for you!

zmodelerlover / OpenNR-ReShade

AMD Neural Rendering: a ReShade add-on that runs neural rendering on Radeon. RDNA3/RDNA4, Direct3D 11 and emulators. Vulkan, OpenGL and 32-bit games experimental.

brummer10 / guitarix

guitarix virtual versatile amplification for Jack/Linux

camunda / camunda-modeler

A modeling solution for BPMN, DMN, and Forms based on bpmn.io. As a companion tool to your favorite IDE it supports you in implementing solutions with Camunda.

Volland / lpg-modeler

Design a labeled property graph once. Generate LadybugDB DDL, Neo4j constraints, SHACL shapes and an OWL ontology from it. VS Code extension + CLI.

Miragon / bpmn-cli

Let your AI agent model BPMN like a pro: semantic edits instead of XML, clean auto-layout, linting and PNG renders – all from one CLI. Give it a try 🚀
