FastRPC is a DevTools extension for the Chrome browser created by Ondřej Žára from Seznam.cz. This free extension adds a new panel to the DevTools interface, specifically designed to display decoded FastRPC requests and responses. FastRPC supports protocol versions 1, 2, and 3.

The main purpose of FastRPC is to provide developers with a convenient way to analyze and debug FastRPC communication. With this extension, developers can easily view the decoded content of FastRPC requests and responses, allowing them to understand the data being transmitted and troubleshoot any issues that may arise.

The additional panel provided by FastRPC is a valuable tool for developers working with FastRPC. It enhances the capabilities of the Chrome DevTools, making it easier to work with this binary protocol. By decoding the requests and responses, developers can gain valuable insights into the inner workings of their FastRPC-based applications.
