Fix React UI issues visually with AI
Click any element in your React app. Describe the fix. PulseDev's AI analyzes your components, hooks, and styles — then writes production-ready code changes instantly.
What is React?React dominates the frontend. Fixing UI bugs still feels like 2018.
React is the most widely-used JavaScript library for building user interfaces. Yet debugging component styles, prop-driven layouts, and CSS-in-JS across dozens of files remains a manual grind.
PulseDev vs. the old way
How React developers fix UI issues — before and after PulseDev.
Inspecting elements, tracing props through component trees, cross-referencing stylesheets — a typical React UI bug eats half an hour.
Click the element, type the fix in plain English. PulseDev writes JSX and CSS changes, previews them live via HMR.
PulseDev sees your rendered DOM and component source simultaneously — no more context-switching between browser and editor.
