React-Map, created by Achmad Akif (achmadakif), is a Chrome DevTools extension that converts a React application's internal structure into a visual map for debugging and architecture review. The app renders the Fiber tree as a diagram and offers targeted tools for locating and inspecting parts of a component graph. It is aimed at frontend engineers who work on large React codebases and prefer spatial exploration to nested lists.

Access and integration depend on the React Developer Tools panel

The tool installs as a dedicated panel inside Chrome DevTools, so it requires the official React Developer Tools extension to be active before use. Once visible, the map reflects the running app's component layout and updates as the inspected page changes, which places the workflow entirely inside DevTools rather than in a separate window or external service.

All component data and processing stay within the browser

React-Map performs its work locally inside the DevTools context and does not require an account, so component trees and props do not leave the machine. The project is published as open-source on GitHub, allowing developers to inspect the codebase and contribute, a point that supports teams with concerns about third-party telemetry or closed-source tooling.

Focused on local debugging workflows, not production inspection

The extension targets localhost development sessions and is designed around in-browser debugging rather than running against arbitrary production sites. That design choice keeps its interface concentrated on developer workflows and limits its intended scope when diagnosing issues that only reproduce in deployed environments.

Fits a specialist audience and runs on Chromium-based browsers

The tool is intended for React specialists who need a higher-level view of component architecture, and it is available for Chrome and other Chromium-based browsers. User feedback shows a positive reception among developers working with deeply nested component trees, making the app a niche addition to an engineer's debugging toolbox rather than a general-purpose inspector.

React-Map is a focused architectural aid for React developers

React-Map suits engineers who want a spatial way to examine component relationships during local development, particularly on complex projects. Its local-only processing and open-source model make it suitable for teams that prioritise code transparency. The trade-off is its narrow scope: it is a development-time visualiser rather than a universal runtime inspector for production environments.
