Frontman places an AI development agent in a framework or browser environment for working with code.
About Frontman
Frontman is an AI coding agent that runs in the browser alongside a running web application. A user clicks an element on the page, describes the change in plain English, and Frontman edits the matching source files, with hot reload applying the change. It uses the live DOM, component tree, computed CSS, routes, source maps, and server logs to find the component that renders the element. The homepage says generated diffs can be reviewed before they land and then sent through a team's normal review process. The homepage describes Frontman as open source under Apache 2.0 or AGPL-3.0, but the directory record does not mark it as open source, so check the repository license before relying on it. Pricing is unknown.
The homepage describes Frontman as built for small frontend changes, such as copy, spacing, colors, layout, and internal UI polish. It is not presented as a replacement for a full IDE. The comparison on the homepage describes it as complementary to tools such as Cursor and GitHub Copilot, which it lists for backend work and general refactoring. The comparison table also notes that Frontman uses framework middleware to read rendered output.
Key features
- Click an element in a running app and describe the change in plain English
- Edits the underlying source files and applies changes with instant hot reload
- Reads the live DOM, component tree, and computed CSS of the rendered page
- Uses source maps to identify the component that renders a selected element
- Uses routes and server logs as additional context for changes
- Generated diffs can be reviewed before changes are applied
Best for: Product managers, designers, and frontend developers who need small frontend fixes made in the browser and then reviewed through their normal process.
Good for
- Lets non-technical teammates make frontend fixes without opening an IDE
- Works from the rendered page, so it can account for computed CSS and component structure
- Sends changes through the team's existing review process as a diff
Watch out for
- Built for small frontend changes rather than full-stack development
- Needs framework middleware to see rendered output, according to the homepage comparison table
- Open-source status differs between the homepage and the directory record, so the license should be checked
