One platform to build, fine-tune, and deploy ML models. No MLOps team required.
Access Gemini 3 and 200+ models. Build chatbots, agents, or custom models with built-in monitoring and scaling.
Planimetric Geometry (JCabri) is a rewrite of Cabri Geometry in Java. It provides solution for doing geometric constructions in 2D and exporting them as an animated GIF or Java applet.
Scene Beans is an animation framework for Java2D. Scene Beans lets the programmer create animations by composing Java objects in a declarative style and hides the details of exactly how that animation is animated and rendered.
Netsim is a mobile ad hoc network simulator targeted at large heterogeneous node configurations. It is written in Java and is easily extensible through its modular concept.
TouchGraph provides a set of interfaces for graph visualization using force-based layout and focus+context techniques. For now only older code is available, but we are planning to release new versions as well.
A java based digital logic simulator, designed to be used as an educational tool.
uses a GUI to allow users to quickly and easily create and visualise circuits from simple components. User can create custom components
JViz is a prototype 3d visualization application that was created to help beginning Java programmers understand the structure, design and coding habits of their Java programs, and which parts of their programs need the most improvement.
Raytracing rendering engine written in Java. Plug it into a modeling environment, or programmatically create a scene. Uses Constructive Solid Geometries (CSG), bounding boxes, and fully extensible design (at least eventually).
Auth0 Token Vault handles secure token storage, exchange, and refresh for external providers so you don't have to build it yourself.
Rolling your own OAuth token storage can be a security liability. Token Vault securely stores access and refresh tokens from federated providers and handles exchange and renewal automatically. Connected accounts, refresh exchange, and privileged worker flows included.
NecJGui is an antennas design tool, interface for Numerical Electromagnetic Code. It allows easily making NEC input files, and viewing them in 3D. It also contains a version of the simulator, so it's complete IDE for full-wave EM simulation.
JFacedec is aimed to build a flexible face detection system based on Java. The plug-in framwork makes it easy for you to share your own Training & Detection Algorithms, compare different methods and make progress together in this field.
A very flexible and extendable Java layout engine that uses XML to render Java user interface components and separate the data model from visualization.
A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.
