WebVB Studio is a web-based Visual Basic 6 and Python IDE that runs entirely in the browser. It lets you design forms visually with a drag-and-drop designer, write code in VB6 or Python, and run your applications instantly -- no installation or backend server required.
- Visual Form Designer -- Drag-and-drop controls onto a WYSIWYG canvas
- Dual Language Support -- Write in Visual Basic 6 or Python (via Pyodide/WebAssembly)
- 30+ Built-in Controls -- Buttons, TextBoxes, Labels, ListBoxes, Tables, Charts, Gauges, Canvas, and more
- Database Support -- SQLite (sql.js) and key-value Database controls
- REST API Client -- GET, POST, PUT, DELETE with headers, auth tokens, and JSON parsing
- MQTT / IoT Support -- Full MQTT 3.1.1 client over WebSocket for real-time dashboards
- AI Assistant -- Code generation powered by Google Gemini and Anthropic Claude
- Report Designer -- Printable reports with grouping, filtering, and expressions
- Cloud Storage -- Dropbox integration via OAuth PKCE
- Built-in Debugger -- Breakpoints, step-over, step-into, variable watch
Everything runs client-side in the browser using React, TypeScript, WebAssembly (Pyodide for Python, sql.js for SQLite), and the Web Crypto API.

.webvb— VB6-style project (default language: VB).pyvb— Python project (default language: Python)
Both formats contain identical controls and UI layout. The only difference is the default language when opened. Each file is a self-contained JSON document with the following structure:
{
"forms": [{ "id": "...", "name": "Form1", "controls": [...], "vbCode": "...", "pyCode": "..." }],
"activeFormId": "...",
"language": "vb | python",
"projectProperties": { "name": "...", "description": "...", "author": "WebVB Studio", ... },
"version": "3.0"
}Here are some highlighted examples to get you started:
