+## Introduction
+
+## gRPC Web UI - BETA <a href="gRPC-Web-Ui" id="grpc-web-ui"></a>
+
+The **gRPC Web UI** is a tool for querying gRPC. Currently in **BETA**, this web-based user interface allows you to interact with gRPC servers directly from browser. Similar to Postman, but specifically designed for gRPC APIs instead of REST.
+

+
+## What is gRPCui?
+
+gRPCui is a command-line tool that provides a web-based user interface for gRPC. It allows to:
+- Query gRPC servers
+- Interact with gRPC APIs
+- Visualize responses in a user-friendly format
+
+## Features
+
+`grpcui` supports all RPC methods, including streaming. However, you must construct the entire stream of request messages at once, and it renders the entire response stream at once, unlike `grpcurl` which allows bidirectional interaction.
+
+- `grpcui` supports plain-text and TLS servers, with various TLS configuration options, including mutual TLS with client certificates.
+
+- Upon issuing an RPC, the web UI displays all gRPC response metadata, including headers and trailers, and presents the response body in a human-readable HTML table.

+
+## How to Use gRPCui
+
+1. Access the tool at [https://juno.grpcui.chaintools.host/](https://juno.grpcui.chaintools.host/) or install the tool from [grpcui](https://github.com/fullstorydev/grpcui/).
+
+To be an example, let's query tokenfactory module params. For this, choose osmosis.tokenfactory.v1beta1.Query service name.
+![Service Name](../.gitbook/assets/grpc-web-ui-service_name.png)
+
+Then, choose Params method name:

+![Method Name](../.gitbook/assets/grpc-web-ui-method_name.png)
+
+2. Use the interface to query the server and visualize the responses.

+
+And, the response:
