JSON-RPC Rewriter — Testing Tool for Frontend Developers and QA.

An essential extension for manual testing and frontend development. JSON-RPC Rewriter lets you intercept JSON-RPC requests

directly in the browser and substitute the response body and headers — without touching the backend.

Working on an app that communicates via JSON-RPC? Need to check how the frontend handles a specific server response — an error,

an edge case, or particular data? Just define the desired response in the extension and the browser will receive exactly that.
