About Frontman
Frontman is an open-source AI agent that runs inside your browser and dev server, observing your live DOM, styles, and component tree in real time. It translates plain-English instructions into in-place code edits and instant UI updates, connecting to models like Claude or ChatGPT. The tool honors your project rules, produces reviewable diffs, and reduces hallucinations while eliminating context-switching. Developers, designers, and product managers can iterate faster without switching tools or losing focus. By operating directly within the browser, it bridges the gap between natural language requests and executable code changes. The agent maintains awareness of your project’s structure, ensuring edits align with existing conventions and dependencies. Reviewable diffs provide transparency, making it easier to audit changes and collaborate with teammates. It supports real-time collaboration, allowing multiple users to see updates as they happen.
