Frontman
Frontman is an open-source AI coding agent designed to live inside the browser, providing a deeply integrated development experience. It connects directly to your local development server, gaining real-time access to the live DOM, component tree, CSS, routing information, and console logs. By understanding the exact state of your application as it runs, Frontman can make intelligent suggestions and modifications that are immediately visible. Users interact with Frontman through natural language commands, and it edits the actual source files in your project, triggering instant hot reload to reflect changes in the browser without manual refreshes. This tight feedback loop eliminates the need to constantly switch between code editor and browser, streamlining the front-end development workflow. Frontman leverages advanced language models to interpret developer intent and propose contextually relevant code changes. It can generate, modify, and refactor UI code, styles, and logic based on a holistic view of the application. Because it sees both the source code and the live rendering, it can spot discrepancies, suggest optimizations, and fix bugs with remarkable accuracy. The tool is built to be extensible and open source, allowing the community to contribute adapters for different frameworks and custom plugins. Developers can use Frontman for a wide range of tasks, from rapid prototyping to precise pixel-level adjustments. It aims to make front-end development more intuitive and less fragmented by collapsing the edit-preview-debug cycle into a single browser-based environment. With its ability to directly manipulate source files and observe the application in real time, Frontman represents a new paradigm for AI-assisted coding.

Problem solved
Front-end developers often experience friction from constantly switching between their code editor and browser to inspect, debug, and implement UI changes. This context switching breaks flow, slows iteration, and makes it hard to connect visual issues with the underlying code. Frontman solves this by embedding an AI coding assistant directly into the browser preview of the application. It observes the live DOM, component tree, CSS, routes, and logs, and can edit the actual source files with instant hot reload. This eliminates the editor-browser divide, allowing developers to describe changes in natural language and see them applied in real time, drastically speeding up development and reducing frustration.
Use cases
- Rapidly prototype UI components by describing them in natural language and seeing instant hot reload updates.
- Fix CSS layout issues by instructing the AI to adjust styles while inspecting the live DOM.
- Add new routes or components by speaking a feature request, with the AI generating and linking the necessary files.
- Debug runtime errors by letting the AI analyze console logs, network requests, and the component tree to propose fixes.
- Refactor large component trees by asking the AI to reorganize or extract reusable parts based on live dependencies.
- Optimize performance by having the AI identify and correct unnecessary re-renders or heavy computations visible in the live application.
Audience
- Developers
Pros
- Deep browser integration provides real-time DOM, CSS, and routing information for highly context-aware edits.
- Eliminates editor-browser context switching, keeping developers in flow.
- Instant hot reload ensures changes are reflected immediately, enabling ultra-fast iteration.
- Open-source and community-driven, with potential for framework adapters and extensions.
- Natural language interface makes it accessible and reduces the need for manual code navigation.
Cons
- Limited to browser-based web applications; not suitable for mobile or desktop app development outside the browser.
- Requires a local development server and specific setup; may not work seamlessly with all project configurations.
- Reliance on AI accuracy means occasional incorrect suggestions that must be reviewed carefully.
