MobX DevTools is a browser extension and standalone debugging tool for MobX applications.
The tool addresses the challenge of understanding state changes and dependencies in MobX-based applications. It works by connecting to your running application to track changes to observables, visualize the dependency tree, and inspect mobx-state-tree stores directly from your browser. The extension is available for Chrome and Firefox, with a standalone app option for browsers that do not support extensions.
Developers working with MobX should choose this tool if they need visibility into observable state changes during development. It suits any MobX application, whether using plain MobX or mobx-state-tree. The tool supports MobX versions 2.2 through 6.x and works with any version of mobx-state-tree. One limitation to be aware of is that the DevTools cannot connect to applications running inside an iframe.
The project receives issue reports primarily from outside users rather than from the core team, indicating a substantial base of adopters relying on it in real-world applications.
