Logs-React is not a standalone piece of software. It is a React Component design to be used as an addition to any React application that sends or recieves JSON-RPC calls. It will expose JSON-RPC requests, responses, and notifications in a filterable time-series. Any requests and that have been made can be easily re-sent using the component.
Logs-React is used in Open-RPC's Inspector tool which is used by the Open-RPC Playground web application. Try out the playground web application here .
