About
JSX Tool builds a browser-first React IDE and Chrome extension that lets developers inspect, style, edit, and generate JSX directly in a live browser. It sells primarily to React developers and differentiates itself by connecting rendered UI elements to source code and AI-assisted edits in one workflow.
Market
JSX Tool competes in React developer tooling, specifically browser-based component inspection, source-code navigation, and visual editing. It positions itself as a React-focused browser IDE that connects rendered UI elements to project JSX and the local filesystem, differentiating it from React Developer Tools’ hierarchy inspection and LocatorJS’s primarily browser-to-VS Code navigation by combining inspection, in-place style editing, code navigation, and real-time component editing.
JSX Tool targets frontend and React developers, particularly startup teams building React applications. Its buyer/user is primarily the hands-on developer who wants to inspect, edit, and navigate application code directly from the running browser UI.
At a Glance
Problem
React developers often lose time moving between the browser, DevTools, and their editor to determine which component rendered a visible element and then validate small JSX or CSS changes. React DevTools is useful for inspecting component trees, props, state, and performance, but it is not designed for styling; in larger codebases, tracing an element back through folders and packages makes routine UI fixes slower and more error-prone. The killer use case is selecting an element in the running application, jumping directly to its JSX, and iterating on the design without a manual copy-and-paste edit–preview loop.
Product / Service
JSX Tool is a Chrome extension paired with a lightweight local development server and an in-browser React IDE. Developers can hover over or click an element, inspect the corresponding component, search the codebase, and edit styles or JSX in the developer panel. AI features use live browser context to propose CSS changes and variations, while accepted edits can be written back to local source files through the dev server and hot-reloaded into the application. The product has a free tier and paid Individual and Organization plans listed at $16.67 and $33.33 per seat per month respectively when billed annually.
Market
JSX Tool competes in React developer tooling at the intersection of component inspection, visual debugging, browser-based IDEs, and AI-assisted coding. Its adjacent competitors include React Developer Tools, LocatorJS, and React Inspector for locating components in source, as well as StackBlitz for browser-based React development. JSX Tool’s distinction is combining click-to-source navigation with live styling, in-browser code editing, AI-assisted changes, and persistence back to the developer’s local codebase.
The product appears to be in an early commercial-launch phase rather than at demonstrated scale. The Chrome Web Store listed 2,000 users and six ratings, while the open-source dev-server repository showed 179 stars and 21 forks; JSX Tool also launched publicly as a YC F25 company on Hacker News. Public materials show a free-to-paid pricing model, but the reviewed sources do not disclose revenue, paid-customer counts, or other evidence of significant commercial traction.
