Features & Capabilities

gRPC-Web Developer Tools is a powerful Firefox DevTools extension designed for developers working with the official gRPC-Web library. It simplifies debugging by allowing you to inspect gRPC client network requests directly within Firefox Developer Tools. Unlike standard network tabs, this tool specifically filters and logs gRPC-Web requests, displaying them as deserialized JSON objects instead of cumbersome base64 encoded binaries.

Once installed, a dedicated gRPC-Web tab appears in the Developer Tools interface. This tab records your application's gRPC requests and responses, providing clear, readable views of requests, responses, and any error objects returned by the gRPC server. This makes diagnosing issues and understanding application behavior much more straightforward and efficient for web developers working with gRPC technologies.

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

gRPC-Web Developer Tools requires a few sensitive permissions. Exercise caution before installing.
