OpenSumi DevTools is a specialized Chrome extension designed for developers using OpenSumi-based IDEs. This tool enhances the development experience by providing essential features for monitoring and analyzing communication between the frontend and backend of applications. It supports both Web and Electron clients, making it versatile for various development environments.

Key functionalities include the ability to capture and display Remote Procedure Call (RPC) messages, allowing developers to visualize the communication flow within their applications. Additionally, it provides statistics on RPC traffic and network latency, which can aid in performance optimization. For Electron applications, it also captures Inter-Process Communication (IPC) messages, further enriching the debugging capabilities for developers working in that environment.
