OpenAI Agents JS
A lightweight, powerful framework for multi-agent workflows
openai-agents-js is the JavaScript/TypeScript version of the OpenAI Agents SDK, designed to give developers a lightweight but powerful framework for building agentic workflows, voice agents, and tool-augmented LLM systems in JS/TS environments. The SDK is provider-agnostic, meaning while it’s deeply compatible with OpenAI’s APIs, you can also adapt it to use other backends or extension layers. At its core, it introduces primitives like Agents, Tools, Guardrails, and Handoffs, letting you define structured multi-agent systems in a modular way. The repo includes examples showing how to build agents that call local functions, chain between agents, validate input/output, stream responses, and interact in real time (e.g. voice agents via WebRTC). It also has tracing and debugging support so you can introspect how agents executed their workflows. Because it aligns closely with the Python Agents SDK, it aims for cross-language parity so that JS/TS devs can adopt similar agent architectures. -

Orchard Core
Open-source modular and multi-tenant application framework
Open-source, modular, multi-tenant application framework and CMS for ASP.NET Core. Orchard Core is a redevelopment of Orchard CMS on ASP.NET Core. Orchard Core consists of two different targets, Orchard Core Framework, an application framework for building modular, multi-tenant applications on ASP.NET Core, and Orchard Core CMS, a web content management system (CMS) built on top of the Orchard Core Framework. It’s important to note the differences between the framework and the CMS. Some developers who want to develop SaaS applications will only be interested in the modular framework. Others who want to build administrable websites will focus on the CMS and build modules to enhance their sites or the whole ecosystem. One of our goals is to enable community-based ecosystems of hosted applications that can be extended with modules, like eCommerce systems, blog engines and more. -
