Blockly is a block-based coding library and visual programming editor that allows users to build programs by interlocking graphical blocks. It functions as a visual code generator, translating these arrangements of logic blocks and variables into executable source code for various programming languages. The library provides a framework for creating custom visual programming languages and low-code logic designers. It utilizes an SVG-based UI library to render interactive, draggable elements on a web canvas. The system is designed as an accessible web UI framework with integrated keyboard navi
Rivet is a visual LLM workflow designer and AI agent orchestration engine. It serves as a development environment for building retrieval augmented generation pipelines and a TypeScript library for embedding visual AI graphs and prompt logic into JavaScript applications. The system differentiates itself through a node-based editor that maps data flow between language models, vector databases, and external APIs. It provides specialized tools for prompt engineering, including interfaces for iterative prompt refinement and A/B testing to improve model response quality. The platform covers a broa
Stateless is a .NET state machine library used to manage complex object behaviors and lightweight workflows through C# code. It functions as an asynchronous workflow engine that executes state transitions, guards, and entry-exit actions using asynchronous tasks. The library implements a hierarchical state machine, allowing child states to inherit transitions and properties from parent superstates. It includes a state persistence framework that decouples state tracking from machine logic by reading and writing the current state to external properties or databases. Additionally, it features a g
