Frontman.sh

Frontman is an AI Agent that lives in your browser, sees your live DOM, and turns your visual feedback into real changes โ€” no more refresh-and-check cycles.

Frontman - Edit your frontend from the browser.

No code editor needed.

You know the drill - You spot a spacing issue, a wrong color, copy that doesn't read right.

So you open a ticket. Tag a developer. Wait. Get a build back that's almost right. Repeat. Frontman ends that cycle. It's an open-source AI agent that lives inside your running app during development. Open your browser, click the element you want to change, and describe what you need in plain English. Frontman sees your live UI โ€” the actual DOM, styles, layout, component tree โ€” and writes the code change in real time. You watch it happen. No IDE. No terminal. No alt-tabbing. What this means for you: - Click, don't describe. Select any element on the page โ€” a button, a card, a hero section. Frontman knows exactly which file, which line, which component it maps to. No more annotated screenshots or Loom recordings. - Make changes yourself. Adjust spacing, swap copy, try a different layout. You're not writing code โ€” you're having a conversation. The AI handles the implementation while you stay focused on what things should look and feel like. - See results instantly. Changes stream into the codebase and hot-reload in the browser as they're written. No waiting for a build. No "can you try it 2px smaller" follow-up tickets. - Ship with confidence. Every change goes through normal code review and version control. Nothing hits production without engineering sign-off. Your developers stay in the loop โ€” they just don't have to context-switch for every pixel adjustment. Frontman works with Next.js, Astro, and Vite. It connects to Claude, ChatGPT, or any model via OpenRouter. Install in under 5 minutes with a single command. Stop filing tickets for things you can see and fix yourself. Your AI finally sees what you see. Open source. Free beta. frontman.sh (https://frontman.sh)

Features & Specs

  1. Live DOM Awareness

    Other AI tools read your source files and guess what the UI looks like. Frontman runs inside your browser and sees the actual rendered DOM, computed styles, and component tree. The agent makes decisions based on what's real, not what it imagines.

  2. Click-to-Edit Element Selection

    Point at any element in your running app โ€” a button, a card, an entire section. Frontman highlights it, resolves it to the exact source file and line number, and lets you describe the change in plain English. No file hunting, no line references.

  3. Source Location Resolution

    When you click an element, Frontman traces through React fibers or framework annotations to find the exact component, file, line, column, props, and full parent chain. The agent knows precisely where to edit before it writes a single character.

  4. Visual + Structural Context in Every Prompt

    The agent receives a screenshot of the selected element AND its source location simultaneously. It sees both what the component looks like and where it lives in code โ€” something no terminal-based tool can do.

  5. Component Tree Navigation

    Here are 10 unique features that differentiate Frontman from other AI coding agents: --- 1. Live DOM Awareness Other AI tools read your source files and guess what the UI looks like. Frontman runs inside your browser and sees the actual rendered DOM, computed styles, and component tree. The agent makes decisions based on what's real, not what it imagines. 2. Click-to-Edit Element Selection Point at any element in your running app โ€” a button, a card, an entire section. Frontman highlights it, resolves it to the exact source file and line number, and lets you describe the change in plain English. No file hunting, no line references. 3. Source Location Resolution When you click an element, Frontman traces through React fibers or framework annotations to find the exact component, file, line, column, props, and full parent chain. The agent knows precisely where to edit before it writes a single character. 4. Visual + Structural Context in Every Prompt The agent receives a screenshot of the selected element AND its source location simultaneously. It sees both what the component looks like and where it lives in code โ€” something no terminal-based tool can do. 5. Component Tree Navigation Use arrow keys to walk up from a button to its card container to the page section. Each level gives the agent broader structural context. You choose the scope of the change by choosing the level of the component hierarchy

  6. Automatic Page Context Injection

    Every prompt silently includes the current route, viewport dimensions, device pixel ratio, color scheme preference, and scroll position. The agent makes responsive and context-aware decisions without you having to explain where you are or what you're looking at.

  7. Server-Side Log & Build Error Access

    Frontman captures console output, build errors, uncaught exceptions, and compilation warnings from your running dev server. The agent can query these logs by level, timestamp, or regex pattern โ€” diagnosing issues that span both browser and server.

  8. Framework-Level Middleware Integration

    Frontman doesn't screenshot your app from the outside. It embeds into your framework's build pipeline (Next.js, Astro, Vite) as middleware, turning your local dev server into an MCP server. It knows your routes, your pages, your layouts โ€” structurally, not by guessing from filenames.

  9. Dual Execution Context (Browser + Server)

    The agent can simultaneously take screenshots and navigate in the browser while reading files, writing code, and running searches on the dev server. Two execution environments, one unified agent โ€” no other tool operates across both contexts.

  10. Browser-Native Access for the Whole Team

    No IDE, no terminal, no Git knowledge required. Designers and PMs open localhost/frontman in a browser, describe changes in a chat, and produce real code diffs that go through standard code review. The tool that was always developer-only is now for everyone.

Questions & Answers

As answered by people managing Frontman.sh.

  1. What makes Frontman.sh unique?

    Frontman is the only AI coding agent that runs inside your browser, connected to your live application. While every other tool - Cursor, Claude Code, Copilot - operates in a terminal or IDE reading source files, Frontman has direct access to the rendered DOM, computed styles, component tree, server logs, and build state simultaneously. You click a UI element, describe what you want in plain English, and watch the code change stream in with live hot-reload. It bridges two worlds no other tool touches at once: the browser and the codebase.

  2. Why should a person choose Frontman.sh over its competitors?

    Competitors guess what your UI looks like from code. Frontman sees it. When you select an element, it resolves the exact source file, line, component, and parent chain - then receives a screenshot alongside the structural data. That means fewer hallucinated layouts, no refresh-and-check loops, and no alt-tabbing between editor and browser. It also runs entirely in the browser, so your designers and PMs can make real changes without learning an IDE. And it's open source - every prompt, every tool call, every piece of context is visible in the code. No black box.

  3. How would you describe the primary audience of Frontman.sh?

    Frontend developers who want faster iteration with richer context than terminal-based AI tools. Designers who want to fix spacing, swap copy, or try layout variations without filing a ticket and waiting. Product managers and QA who want to make minor UI changes themselves without opening an IDE. Any team where the gap between "seeing a problem" and "fixing it" is slowed down by handoffs.

  4. What's the story behind Frontman.sh?

    Frontman was born from a simple frustration: AI coding tools are blind. They read your source files but have never seen your UI. They generate code and hope it looks right. Meanwhile, designers send annotated screenshots, PMs write tickets for two-pixel adjustments, and developers alt-tab endlessly between editor and browser. Frontman was built to collapse that gap - an AI agent that lives where the work actually happens, inside the running application, where everyone on the team can see and shape the frontend together.

  5. Which are the primary technologies used for building Frontman.sh?

    • ReScript and React for the browser client and all framework integrations
    • Elixir and Phoenix for the real-time server backend with WebSocket communication
    • Astro and Tailwind CSS for the marketing site
    • PostgreSQL for persistence
    • MCP (Model Context Protocol) to expose dev server tools to the agent
    • ACP (Agent Client Protocol) for real-time agent-to-client streaming over Phoenix channels
    • Framework middleware for Next.js, Astro, and Vite that turns the local dev server into an MCP server

  6. Who are some of the biggest customers of Frontman.sh?

    Frontman is currently in free open-source beta and does not publicly disclose customer names. The product is community-driven with adoption through: - GitHub open-source contributors - Discord community members - Early-adopter frontend teams using it with Next.js, Astro, and Vite projects No named customer logos or case studies are published at this stage.
