Comparison
AI Coding Tools Compared
How Frontman stacks up against Cursor, Claude Code, GitHub Copilot, Windsurf, and Stagewise. Feature matrix, pricing, and architecture differences.
Frontman is an open-source AI coding agent that runs as framework middleware in your browser. It hooks into Next.js, Astro, or Vite, sees the live DOM and computed CSS via a browser-side MCP server, and lets you click elements to edit their source code with hot reload. The tools below approach AI-assisted coding from different directions. This page shows where they overlap and where they don't.
Tool Categories
These tools are not all the same kind of thing. Understanding the category helps you pick the right one.
Browser Middleware
Frontman
Installs as a framework plugin. Runs inside your dev server. Sees the rendered page from the inside: component tree, computed styles, routes, logs.
AI IDEs
Cursor, Windsurf
VS Code forks with built-in AI agents, autocomplete, and terminal integration. Work from file context. Windsurf adds an embedded browser preview panel.
Terminal Agent
Claude Code
Runs in your terminal or IDE. Reads the full codebase, edits files, runs commands, handles git. Language-agnostic. Chrome extension (beta) for limited browser access.
IDE Assistant
GitHub Copilot
IDE extension with inline autocomplete, agent mode, and code review. Works across any language. Integrated into the GitHub platform for PRs and issues.
Browser Overlay
Stagewise
Zero-install CLI overlay injected into the browser. Bridges to IDE agents (Cursor, Copilot, etc.) or uses a built-in agent with prompt limits.

What makes Frontman different from all these tools?
Frontman is the only tool on this list that runs as framework middleware inside your dev server. It hooks into Next.js, Astro, or Vite as a plugin, which gives the AI agent access to the live DOM, computed CSS, the framework component tree (React, Vue, Svelte), server-side routes, and compilation errors. Other tools either read source files from an IDE (Cursor, Copilot, Windsurf), work from a terminal (Claude Code), or see a shallow DOM snapshot (Stagewise). Frontman sees the full runtime context.
Can I use Frontman alongside these other tools?
Yes. Frontman runs in your browser and edits source files. You can use any IDE (Cursor, VS Code, Windsurf, JetBrains) and any terminal tool (Claude Code) alongside it. They all edit the same files, and hot reload keeps everything in sync. The typical workflow is: IDE-based tool for backend and refactoring, Frontman for visual frontend work.
Which tool should I use if I only pick one?
If you primarily do frontend work on Next.js, Astro, or Vite projects and want the AI to see what the page looks like: Frontman. If you need a full IDE with autocomplete for any language: Cursor or Windsurf. If you want a terminal-native agent for complex multi-file tasks: Claude Code. If you want inline autocomplete integrated into GitHub: Copilot. These tools are better together than alone.
Is Frontman really free?
Yes. The client libraries are Apache 2.0 and the server is AGPL-3.0. You self-host and bring your own API keys to Claude, ChatGPT, OpenRouter, or any OpenAI-compatible provider. You pay those providers directly at their standard rates. There are no prompt caps, no credit system, no monthly subscription from Frontman. Paid hosted tiers are planned but the open-source core will stay free.
Try Frontman
