gRPC-Web Developer Tools is a Chrome DevTools extension developed by SergioTx for debugging application's gRPC-Web network requests. This free tool allows developers to inspect the gRPC network log in the Chrome Developer Tools and view it as deserialized JSON objects, instead of the base64 encoded binary format.

Upon installation, a new tab called gRPC-Web is added to your Chrome DevTools. This tab records gRPC client network requests that have been configured. The features offered by this extension are similar to the default Network tab, but it specifically tracks gRPC requests.

One of the key features of gRPC-Web Developer Tools is the ability to select a network log entry and view the deserialized JSON for the request, response, and any error objects returned by your gRPC server. This provides developers with valuable insights for debugging and troubleshooting their gRPC-Web applications.

gRPC-Web Developer Tools is a fork of the original extension available at the Chrome Web Store, with additional fixes and improvements made by SergioTx.
