Comparison
Frontman vs Stagewise
Two Browser-Based AI Coding Tools, Different Architecture
Frontman and Stagewise both let you click elements in your running app, describe changes in natural language, and get real source code edits. They solve the same problem — AI coding tools that can't see the browser — but with fundamentally different architectures.
Frontman is an open-source AI coding agent that hooks into your dev server as framework middleware (Next.js, Astro, Vite). It runs its own self-contained agent with deep access to the component tree, computed styles, server routes, and server logs. Free and unlimited — you bring your own API keys.
Stagewise is a YC-backed CLI tool that injects a toolbar into your browser. It captures DOM context and routes it to its own built-in agent or bridges to IDE agents like Cursor, Copilot, and Windsurf. Framework-agnostic with zero codebase changes, but limited to 10 free prompts/day (€20/month for 100/day).
The core tradeoff: Stagewise is faster to try and bridges to your existing IDE. Frontman goes deeper into the framework runtime and remains self-hostable with BYOK.

What Stagewise Does Well
Stagewise has real traction — 6,500+ GitHub stars and YC backing. It deserves credit for popularizing the "click elements in the browser, describe changes" workflow.
Zero installation friction. Run npx stagewise@latest in a terminal next to your dev server. No framework adapters, no config files, no changes to your codebase. You're editing visually in 30 seconds. This is the lowest barrier to entry of any browser-based AI coding tool.
Stagewise can route browser context to your existing IDE agent — Cursor, Copilot, Windsurf, Cline, and others. If you're already invested in an IDE agent's workflow, Stagewise adds browser awareness without switching tools.
Framework-agnostic. Because Stagewise operates as a CLI overlay rather than framework middleware, it works with any framework — including Angular, which Frontman doesn't support. If your stack isn't Next.js, Astro, or Vite, Stagewise is the option that works today.
Plugin system and VS Code extension. Stagewise has an extensibility layer and a dedicated VS Code extension. Frontman currently has neither.
Where Frontman Is Different
Frontman and Stagewise look similar on the surface — both let you click elements and describe changes. The difference is depth. Stagewise injects a toolbar on top of your app. Frontman wires into the app itself.
Framework middleware vs CLI overlay. Frontman installs as a plugin into your dev server — @frontman-ai/nextjs, @frontman-ai/astro, or @frontman-ai/vite. This gives it access to information a CLI overlay can't reach: the React fiber tree, Vue reactivity graph, component props, server-side routes, server logs, and query timing. When you click a button, Frontman knows not just what DOM element it is, but which component rendered it, what props it received, and what server endpoint it calls.
Self-hostable and BYOK. Stagewise's free tier caps you at 10 prompts per day. Their Pro plan is €20/month for 100 prompts/day. Frontman remains free to self-host under its open-source licenses, while hosted Frontman plans are moving to paid subscriptions. You bring your own API keys and pay your LLM provider directly.
Self-contained agent. Frontman runs its own AI agent — it doesn't need Cursor, Copilot, or any IDE running alongside it. The agent has full access to the framework runtime context and generates code edits directly. This means faster iteration (no roundtrip through an IDE agent) and simpler architecture (one tool instead of two).
Because Frontman is framework middleware, it sees both sides: the client-side DOM and the server-side context. It knows your routes, sees server logs, and can access server-side state. Stagewise operates purely on the client side.
True BYOK. Frontman connects directly to any LLM provider — Claude, ChatGPT, OpenRouter, or any OpenAI-compatible API. Stagewise's "bring your own model" works through IDE agent bridges, not direct API key input.
Who Should Use Stagewise
Stagewise is the better choice when you want browser-based AI coding with minimal commitment:
- Quick evaluation — want to try browser-aware AI editing in 30 seconds without installing anything into your project
- IDE agent users — already using Cursor, Copilot, or Windsurf and want to add browser context to your existing agent
- Angular or non-supported framework — your stack isn't Next.js, Astro, or Vite and you need something framework-agnostic
- Occasional use — 10 prompts/day is enough for your workflow and you don't want to manage API keys
Who Should Use Frontman
Frontman is the better choice when you need deeper integration and freedom from prompt limits:
- Daily frontend development — 10 prompts/day isn't enough and you don't want to pay €20/month for a cap of 100
- Next.js, Astro, or Vite projects — Frontman's middleware gives you deeper context than any CLI overlay
- Teams with designers or PMs — non-technical team members can make visual changes without an IDE or a Cursor subscription
- Open-source and vendor-independent — you want full control, BYOK, and a self-hostable development workflow
- Server-side context matters — you need the AI to understand routes, server logs, and server-side state alongside the visual UI
If you hit Stagewise's prompt limits or need deeper framework context, Frontman is worth evaluating.

Frequently Asked Questions
What is the difference between Frontman and Stagewise? +
Both tools let you click elements in your running app and describe changes in natural language. The key difference is architecture: Stagewise is a CLI overlay that injects a toolbar into your browser and can bridge to IDE agents like Cursor. Frontman installs as framework middleware (Next.js, Astro, Vite) and runs its own self-contained agent with deep access to the component tree, props, server state, and computed styles. Stagewise is faster to try (zero install), while Frontman gives deeper framework context and remains self-hostable.
Is Frontman a self-hostable alternative to Stagewise? +
Yes. Frontman can be self-hosted under its open-source licenses, and you bring your own API keys to Claude, ChatGPT, or OpenRouter. Hosted Frontman plans are moving to paid subscriptions, while self-hosting remains available.
Can I use Stagewise and Frontman together? +
In theory, yes — they operate differently. Stagewise injects a toolbar via CLI, while Frontman runs as framework middleware. However, using both simultaneously on the same dev server may cause conflicts. Most developers choose one based on their workflow: Stagewise if they want to bridge to an existing IDE agent, Frontman if they want a self-contained agent with deeper framework context.
Does Frontman work with Cursor like Stagewise does? +
Differently. Stagewise acts as a bridge — it sends browser context to Cursor's agent for code edits. Frontman is a self-contained agent that doesn't need Cursor or any IDE. It has its own AI agent that reads the browser context and generates code edits directly. You can still use Cursor for backend coding alongside Frontman for visual frontend editing — they edit the same source files.
Which tool has deeper browser context? +
Frontman. Because it installs as framework middleware (not a CLI overlay), Frontman has access to the component tree at the framework level — React fiber nodes, Vue reactivity graph, or Svelte component tree. It also sees server-side context like routes, server logs, and query timing. Stagewise sees the DOM and computed styles but operates at a shallower level since it doesn't integrate into the framework's runtime.
Which tool is easier to set up? +
Stagewise. You run npx stagewise@latest in a second terminal and it works with any framework immediately — no changes to your codebase. Frontman requires installing a framework adapter (e.g., npx @frontman-ai/nextjs install for Next.js) which adds a small amount of middleware to your dev server. Frontman's setup takes about 60 seconds more but provides deeper integration in return.
