    Bot Framework Emulator

    Bot Framework Emulator

    Locally test and debug chat bots built with the Bot Framework SDK

    Bot Framework Emulator is a desktop application that allows bot developers to test and debug bots, either locally or remotely. Using the Emulator, you can chat with your bot and inspect the messages that your bot sends and receives. The Emulator displays messages as they would appear in a web chat UI and logs JSON requests and responses as you exchange messages with your bot. Before you deploy your bot to the cloud, run it locally and test it using the Emulator. You can test your bot using the Emulator even if you haven't yet created it with Azure Bot Service or configured it to run on any channels. Before connecting your bot to the Bot Framework Emulator, you need to run your bot locally. You can use Visual Studio or Visual Studio Code to run your bot, or use the command line. When you are developing behind a corporate proxy, the Emulator will use the configured environment variables HTTP_PROXY and HTTPS_PROXY, which specify the proxy URL route for HTTP and HTTPs requests.

    Apollo Server

    Apollo Server

    Spec-compliant and production ready JavaScript GraphQL server

    Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client, including Apollo Client. It's the best way to build a production-ready, self-documenting GraphQL API that can use data from any source. Apollo Server provides a simple API for integrating with any Node.js web framework or serverless environment. The @apollo/server package itself ships with a minimally-configurable, standalone web server that handles CORS and body parsing out of the box. Integrations with other environments are community-maintained. Apollo Server's standalone server lets you get a GraphQL server up and running quickly without needing to set up an HTTP server yourself. It allows all the same configuration of GraphQL logic as the Express integration, but does not provide the ability to make fine-grained tweaks to the HTTP-specific behavior of your server.

    OpenAI Agents JS

    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.
