UiToolbar is an innovative browser extension designed for developers working with React applications. This tool integrates a visual interface with coding agents like Cursor, Claude Code, and OpenAI Codex, enabling users to modify their code directly from the browser. By simply selecting an element, developers can issue commands in plain English to make changes, which are reflected immediately in the source code through hot reload functionality. This eliminates the need for context-switching or manual file handling, enhancing productivity and efficiency.

Key features of UiToolbar include visual element selection, inline text editing, and a move & layout tool that allows for intuitive adjustments to UI components. Additionally, the annotation mode helps track comments and tasks, while the region screenshot capture feature aids in providing visual context for AI prompts. With a user-friendly interface and robust functionality, UiToolbar is a valuable tool for any React developer looking to streamline their workflow.
