Microsoft 365 Agents Playground Microsoft Corporation

Microsoft 365 Agents Playground is a web-based debugging and testing tool designed to help developers refine and iterate on agent/bot applications in an environment that closely emulates various communication channels. This tool provides a sandbox for testing bot behavior, iterating on app design, and ensuring seamless interactions across different platforms.

Key Features:

• Sandbox Environment: Test and debug agent/bot applications in a controlled setting that mirrors the look and feel of real-world communication channels.
• Reduced Debugging Frictions: Eliminate the need for obtaining developer tenants or side-loading permissions, streamlining the debugging process.
• Network Security: Operate without external tunnels like Ngrok or Microsoft Dev Tunnel, enhancing security by keeping applications local.
• Rapid Iterations: Quickly refine app design and bot logic without redeploying to the cloud, enabling faster development cycles.
• Mock Data and Activities: Simulate complex scenarios using mock data and built-in triggers to test functionality and user interactions.
• Reliable UX Rendering: Ensure consistent application rendering by leveraging the same technology used in Microsoft 365 channels for Adaptive Cards.
• Integration Capabilities: Seamlessly integrate with existing applications built using Agent SDK, enhancing flexibility and compatibility.
• Inspection Tools: Analyze interactions and payloads between your application and the playground to identify and resolve issues efficiently.

Audience & Benefit:

Ideal for developers building agent/bot applications, Microsoft 365 Agents Playground accelerates the development process by providing a secure, efficient environment for testing and iteration. It reduces reliance on external tools and cloud deployments, enabling faster feedback loops and improved application quality before production deployment.

The tool is installed via winget and can be integrated into existing workflows to enhance productivity. While it excels in local testing, developers are encouraged to test critical features in real environments (e.g., Microsoft Teams or WebChat) for final validation.
