Comparison
Frontman vs Windsurf
Browser Middleware vs AI IDE
Frontman is an open-source AI coding agent that lives in your browser. It integrates with your framework (Next.js, Astro, or Vite) as a plugin that serves an overlay UI at /frontman. A browser-side MCP server handles DOM inspection, screenshots, computed CSS, and element selection. You click elements in your running app, describe changes in plain English, and Frontman edits the actual source files with hot reload.
Windsurf is a proprietary AI-powered IDE, a VS Code fork with a built-in agent called Cascade. It includes autocomplete (Tab), an embedded browser preview panel, MCP server support, and terminal integration. Originally built by Codeium, now owned by Cognition (the company behind Devin). Windsurf works across any language and framework through file-level context.
The key distinction: Windsurf brings a preview browser into the IDE. Frontman puts the AI agent into your real browser. One adds browser context to an IDE workflow; the other works entirely from the browser.

What Windsurf Does Well
Windsurf has grown into a capable AI IDE with features worth understanding before you compare it to anything else.
Windsurf's agent mode, Cascade, monitors your file edits, terminal commands, and clipboard activity to infer what you're working on. This "flow awareness" means less manual context-providing compared to tools where you have to select files or explain your situation. It often picks up on your intent before you describe it.
Tab autocomplete goes beyond standard inline predictions. Supercomplete predicts your next action beyond single-token completion. Tab-to-Jump moves your cursor where you'll likely edit next. Tab-to-Import handles dependency imports automatically. For developers who rely on autocomplete, this is faster than most competitors.
The embedded browser panel lets you see your running app, click an element, and send it to Cascade. You can also forward console errors directly to the agent. This is closer to visual editing than any other IDE offers, though it works on raw DOM rather than the framework component tree.
Windsurf built its own coding model, SWE-1.5, which they claim runs 13x faster than Sonnet 4.5. Whether the claim holds in all scenarios, having a purpose-built model means some operations (like codebase search via Fast Context) are quicker than routing through general-purpose LLMs.
Windsurf also runs beyond VS Code. JetBrains gets native Cascade integration, and plugins exist for 40+ other editors. Cursor, by comparison, is VS Code-only.
On the enterprise side: SOC 2, HIPAA, FedRAMP/DOD, RBAC, SCIM. If your company has strict compliance requirements, Windsurf has certifications that most competitors lack.
Where Frontman Is Different
Windsurf's embedded browser preview is a step toward visual editing. But there's a structural difference between putting a browser inside an IDE and putting an AI agent inside the browser.
Frontman installs as a plugin for Next.js, Astro, or Vite. It runs inside your dev server rather than alongside it. This means it has access to the component tree (React, Vue, Svelte), server-side routes and logs, compilation errors, and source maps that trace rendered elements back to exact file and line numbers. Windsurf's preview panel sees the rendered DOM, but it doesn't know that a particular <div> is a <ProductCard> component at line 47 of ProductCard.tsx.
Frontman also runs in your real browser, not an IDE panel. It serves at /frontman in Chrome, Firefox, or whatever you test with. You see the same page your users will see, at the same viewport width, with the same extensions and dev tools you always use. Windsurf's preview panel is a controlled embedded browser inside the IDE.
When you click an element in Frontman, the MCP server reads actual computed style values: real pixel dimensions, resolved colors, cascaded font sizes. It doesn't guess from class names. Windsurf's Cascade agent reads your source files and the preview's rendered output, but doesn't have direct access to the CSS cascade or computed values at the level Frontman's browser-side MCP server does.
On licensing: Frontman's client libraries are Apache 2.0, the server is AGPL-3.0, and you bring your own API keys to Claude, ChatGPT, OpenRouter, or any OpenAI-compatible provider. Windsurf is proprietary, uses its own model pool, and charges per-credit. You can't use your own LLM provider or self-host the AI features.
Frontman also doesn't require an IDE. Designers and product managers can open the app in a browser, click elements, and describe changes in plain English. The output is real source code edits for developer review. With Windsurf, you need the IDE installed and you need to know how to use it.
Who Should Use Windsurf
Windsurf is the better choice when you want a full AI IDE that handles everything in one place:
- Developers who want autocomplete, agent mode, and terminal in one tool. Cascade + Tab + terminal is a complete coding environment.
- Full-stack and backend developers. Any language, any framework, with purpose-built code search and refactoring.
- Teams on JetBrains IDEs. Windsurf has native JetBrains integration where Cursor does not.
- Enterprises with compliance requirements. SOC 2, HIPAA, FedRAMP certifications.
- Developers who want visual context without leaving the IDE. The embedded browser preview is a pragmatic middle ground.
Who Should Use Frontman
Frontman is the better choice when you need deep browser context and visual editing:
- Frontend developers who want the AI to see the actual rendered page. Computed styles, component tree, responsive behavior, and server logs in addition to source files.
- Teams where designers or PMs make UI changes. Click elements in the browser, describe changes, review code diffs. No IDE required.
- Next.js, Astro, or Vite projects where framework middleware gives the AI agent more context than file reading alone.
- Open-source and BYOK. Apache 2.0 client libs, AGPL-3.0 server, any LLM provider, self-hostable, no credit system.
- Developers who don't want to switch IDEs. Frontman works with whatever editor you already use. It only needs the browser.
Many developers will use both. Windsurf (or Cursor, or your preferred IDE) for general coding, and Frontman in the browser for visual frontend work where the AI needs to see what's rendered.

Frequently Asked Questions
Is Frontman an alternative to Windsurf?
They solve different problems. Windsurf is a VS Code fork with an AI agent (Cascade), autocomplete, and an embedded browser preview panel. It's a full IDE replacement. Frontman is browser middleware that integrates with your dev server (Next.js, Astro, Vite) and lets you click elements in your actual browser to edit code. For visual frontend editing where runtime context matters, Frontman is the open-source option. For general-purpose AI-assisted coding with a dedicated IDE, Windsurf is the more complete tool.
How does Windsurf's browser preview compare to Frontman?
Windsurf has an embedded browser panel inside the IDE where you can click elements and send them to the Cascade agent. Frontman runs in your actual browser as framework middleware. The practical difference: Windsurf's preview shows the rendered DOM but doesn't know your React/Vue/Svelte component tree, props, state, or server-side context. Frontman's middleware integration sees the full component hierarchy, computed CSS, routes, and logs because it hooks into the framework itself.
Can I use Frontman and Windsurf together?
Yes. Use Windsurf as your IDE for general coding, refactoring, and backend work. Use Frontman in the browser for visual frontend editing where you want to click UI elements and make changes with full runtime context. They edit the same source files and don't conflict.
Is Frontman free compared to Windsurf?
Yes. Windsurf Free gives you 25 Cascade credits per month. Pro is $15/month for 500 credits. Frontman is free to self-host with no limits. You bring your own API keys to Claude, ChatGPT, or OpenRouter and pay those providers directly. No credit system, no monthly subscription from Frontman itself.
What happened to Codeium / who owns Windsurf now?
Windsurf was originally built by Codeium. In mid-2025, Google acquihired the founders and key research staff. Cognition (the company behind Devin, the AI coding agent) then acquired the Windsurf product, IP, and remaining team. As of 2026, Windsurf is owned and operated by Cognition, Inc.
