    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.

    Bolt for JavaScript

    Bolt for JavaScript

    A framework to build Slack apps using JavaScript

    A JavaScript framework to build Slack apps in a flash with the latest platform features. Read the getting started guide to set-up and run your first Bolt app. To listen to messages that your app has access to receive, you can use the message() method which filters out events that aren’t of type message. message() accepts an optional pattern parameter of type string or RegExp object which filters out any messages that don’t match the pattern. A RegExp pattern can be used instead of a string for more granular matching. Within your listener function, say() is available whenever there is an associated conversation (for example, a conversation where the event or action which triggered the listener occurred). say() accepts a string to post simple messages and JSON payloads to send more complex messages. The message payload you pass in will be sent to the associated conversation.

The framework is built specifically to work with AI coding agents, enabling them to read, modify, and execute workflows directly from structured project folders. It eliminates reliance on fragmented SaaS tools by providing all necessary components locally, ensuring better transparency and control over data and processes. Output includes built-in evaluation systems, such as LLM-as-a-judge scoring, and integrates workflow orchestration tools like Temporal to handle retries, parallel execution, and state management. It also supports multiple model providers through a unified API.

    OpenUI

    OpenUI

    The Open Standard for Generative UI

    OpenUI is an open-source framework focused on enabling AI-driven generation and manipulation of user interfaces through natural language and programmatic inputs. The project aims to bridge the gap between design and development by allowing users to describe UI components and layouts in plain language, which are then translated into structured code or interactive components. It leverages modern AI models and frontend technologies to dynamically generate UI elements that can be customized, refined, and extended within development workflows. OpenUI is particularly useful for rapid prototyping, as it allows developers and designers to iterate on interface ideas without manually writing all the underlying code. The framework also supports extensibility, enabling integration with existing design systems and component libraries. By combining AI-assisted generation with developer control, OpenUI provides a hybrid approach to building interfaces that balances automation with customization.

    SST

    SST

    Build serverless apps. Set breakpoints and test your functions locally

    SST is an open-source serverless application platform that deploys to your AWS account, helping you go from idea to IPO. Work on your local Lambda functions lives, without mocking or redeploying your app. Higher-level CDK constructs are made specifically for building serverless apps. Manage the resources in your application with the SST Console. Traditionally, we’ve built and deployed web applications where we have some degree of control over the HTTP requests that are made to our server. Our application runs on that server and we are responsible for provisioning and managing the resources for it. The sst start command starts up a local development environment that opens a WebSocket connection to your deployed app and proxies any Lambda requests to your local machine. Supports all Lambda triggers, so there's no need to mock API Gateway, SQS, SNS, etc. Supports real Lambda environment variables and Lambda IAM permissions.
