React JSX Visualizer & Editor (Windows / Mac)

React JSX Visualizer & Editor is a standalone desktop app that lets you open any React (.jsx/.js) component and see it rendered live — instantly, with no project setup, no npm install, and no configuration. Edit the code on one side and watch the preview update on the other.
