stagewise is a browser toolbar that connects your frontend UI to your code ai agents in your code editor.
- 🧠 Select any element(s) in your web app
- 💬 Leave a comment on it
- 💡 Let your AI-Agent do the magic
Perfect for devs tired of pasting folder paths into prompts. stagewise gives your AI real-time, browser-powered context.
The stagewise Toolbar makes it incredibly easy to edit your frontend code with AI agents:
- ⚡ Works out of the box
- 🛠️ Customise using your own configuration file
- 🔌 Connect to your own MCP server
- 📦 Does not impact bundle size
- 🧠 Sends DOM elements, screenshots & metadata to your AI agent
- 👇 Comment directly on live elements in the browser
- 🧪 Comes with playgrounds for React, Vue, and Svelte (
./playgrounds)
Install the extension here: https://marketplace.visualstudio.com/items?itemName=stagewise.stagewise-vscode-extension
Note
💬 Enable MCP support (Cursor):
- The extension will auto-install a stagewise MCP server.
- Cursor will prompt you to enable the server.
- Click enable to let your agent call MCP-tools that the toolbar provides. (Read more)
Tip
🪄 Auto-Install the toolbar (AI-guided):
- In Cursor, Press
CMD + Shift + P - Enter
setupToolbar - Execute the command and the toolbar will init automatically 🦄
Or follow the manual way:
Install @stagewise/toolbar:
pnpm i -D @stagewise/toolbarInject the toolbar into your app dev-mode:
// 1. Import the toolbar
import { initToolbar } from '@stagewise/toolbar';
// 2. Define your toolbar configuration
const stagewiseConfig = {
plugins: [
{
name: 'example-plugin',
description: 'Adds additional context for your components',
shortInfoForPrompt: () => {
return "Context information about the selected element";
},
mcp: null,
actions: [
{
name: 'Example Action',
description: 'Demonstrates a custom action',
execute: () => {
window.alert('This is a custom action!');
},
},
],
},
],
};
// 3. Initialize the toolbar when your app starts
// Framework-agnostic approach - call this when your app initializes
function setupStagewise() {
// Only initialize once and only in development mode
if (process.env.NODE_ENV === 'development') {
initToolbar(stagewiseConfig);
}
}
// Call the setup function when appropriate for your framework
setupStagewise();⚡️ The toolbar will automatically connect to the extension!
For easier integration, we provide framework-specific NPM packages that come with dedicated toolbar components (e.g., <StagewiseToolbar>). You can usually import these from @stagewise/[framework-name].
React.js
We provide the @stagewise/toolbar-react package for React projects. Initialize the toolbar in your main entry file (e.g., src/main.tsx) by creating a separate React root for it. This ensures it doesn't interfere with your main application tree.
// src/main.tsx
import { StrictMode } from 'react';
import { createRoot } from 'react-dom/client';
import App from './App.tsx';
import { StagewiseToolbar } from '@stagewise/toolbar-react';
import './index.css';
// Render the main app
createRoot(document.getElementById('root')!).render(
<StrictMode>
<App />
</StrictMode>,
);
// Initialize toolbar separately
const toolbarConfig = {
plugins: [], // Add your custom plugins here
};
document.addEventListener('DOMContentLoaded', () => {
const toolbarRoot = document.createElement('div');
toolbarRoot.id = 'stagewise-toolbar-root'; // Ensure a unique ID
document.body.appendChild(toolbarRoot);
createRoot(toolbarRoot).render(
<StrictMode>
<StagewiseToolbar config={toolbarConfig} />
</StrictMode>
);
});Next.js
Use the @stagewise/toolbar-next package for Next.js applications. Include the <StagewiseToolbar> component in your root layout file (src/app/layout.tsx).
// src/app/layout.tsx
import { StagewiseToolbar } from '@stagewise/toolbar-next';
export default function RootLayout({
children,
}: Readonly<{
children: React.ReactNode;
}>) {
return (
<html lang="en">
<body>
<StagewiseToolbar
config={{
plugins: [], // Add your custom plugins here
}}
/>
{children}
</body>
</html>
);
}Nuxt.js
For Nuxt.js projects, you can use the @stagewise/toolbar-vue package. Place the <StagewiseToolbar> component in your app.vue or a relevant layout file.
// app.vue
<script setup lang="ts">
import { StagewiseToolbar, type ToolbarConfig } from '@stagewise/toolbar-vue';
const config: ToolbarConfig = {
plugins: [], // Add your custom plugins here
};
</script>
<template>
<div>
<NuxtRouteAnnouncer />
<ClientOnly>
<StagewiseToolbar :config="config" />
</ClientOnly>
<NuxtWelcome />
</div>
</template>Vue.js
Use the @stagewise/toolbar-vue package for Vue.js projects. Add the <StagewiseToolbar> component to your main App component (e.g., App.vue).
// src/App.vue
<script setup lang="ts">
import { StagewiseToolbar, type ToolbarConfig } from '@stagewise/toolbar-vue';
const config: ToolbarConfig = {
plugins: [], // Add your custom plugins here
};
</script>
<template>
<StagewiseToolbar :config="config" />
<div>
<!-- Your app content -->
</div>
</template>SvelteKit
For SvelteKit, you can integrate the toolbar using @stagewise/toolbar and Svelte's lifecycle functions, or look for a dedicated @stagewise/toolbar-svelte package if available. Create a component that conditionally renders/initializes the toolbar on the client side (e.g., src/lib/components/StagewiseToolbarLoader.svelte or directly in src/routes/+layout.svelte).
Using onMount in +layout.svelte (with @stagewise/toolbar):
<!-- src/routes/+layout.svelte -->
<script lang="ts">
import { onMount } from 'svelte';
import { browser } from '$app/environment';
import { initToolbar, type ToolbarConfig } from '@stagewise/toolbar'; // Adjust path if needed
onMount(() => {
if (browser) {
const stagewiseConfig: ToolbarConfig = {
plugins: [
// Add your Svelte-specific plugins or configurations here
],
};
initToolbar(stagewiseConfig);
}
});
</script>
<slot />Using a loader component (example from repository):
The example repository uses a ToolbarLoader.svelte which wraps ToolbarWrapper.svelte. ToolbarWrapper.svelte would then call initToolbar from @stagewise/toolbar.
<!-- examples/svelte-kit-example/src/lib/components/stagewise/ToolbarLoader.svelte -->
<script lang="ts">
import type { ToolbarConfig } from '@stagewise/toolbar';
// ToolbarWrapper.svelte is a custom component that would call initToolbar
import ToolbarWrapper from './ToolbarWrapper.svelte';
import { browser } from '$app/environment';
const stagewiseConfig: ToolbarConfig = {
plugins: [
// ... your svelte plugin config
],
};
</script>
{#if browser}
<ToolbarWrapper config={stagewiseConfig} />
{/if}You would then use StagewiseToolbarLoader in your src/routes/+layout.svelte.

Check out our project roadmap for upcoming features, bug fixes, and progress.
stagewise is developed by Goetze, Scharpff & Toews GbR under an Open Core model:
- 🧩 99% is open-source under AGPLv3
- 🏢 1% (enterprise features) is commercial
This allows us to:
- Keep core tech open and transparent
- Ensure sustainability and quality
- Prevent misuse by closed-source platforms
We believe this model creates a fair, open ecosystem that benefits both individuals and companies.
We're just getting started and love contributions! Check out our CONTRIBUTING.md guide to get involved. For bugs and fresh ideas, please Open an issue!
