Free Starwind UI Form Builder for Astro

Building forms from scratch is tedious. Writing the markup, styling each field, handling labels and validation states. It adds up fast. What if you could design your form visually and get clean, production-ready code?

The Starwind UI Form Builder is a completely free visual editor for creating Astro forms. Design your form, customize every field, and copy the generated .astro component code directly into your project. No wrestling with code, no cost.

What Is the Starwind UI Form Builder?

It’s a browser-based tool that lets you build forms using Starwind UI components, the open-source component library for Astro and Tailwind CSS v4. If you’ve used shadcn/ui, you’ll feel right at home.

Design your form in a clean visual editor, configure each field’s properties, and export ready-to-use Astro component code. It’s that simple.

Why Use It?

Completely Free

No sign-up required. No license keys. No hidden costs. The Starwind UI Form Builder is 100% free and always will be.

Visual Design, Real Code

Build forms visually without sacrificing code quality. The generated output is clean, idiomatic Astro code using proper Starwind UI components. No bloated abstractions.

Built on Open Source

Every component in your generated form comes from Starwind UI, an open-source library. You’re not locked into a proprietary system. Install the components, own the code, customize freely.

Supported Components

The Astro Form Builder currently supports:

• Input: Text, email, password, number, and more
• Textarea: Multi-line text input with configurable rows
• Select: Dropdown menus with custom options
• Radio Group: A group of radio buttons with labels
• Checkbox: Single checkboxes with labels
• Dropzone: Drag-and-drop file upload

Each field is fully configurable: labels, placeholders, required validation, input types, and more.

Pre-Made Templates

Don’t want to start from scratch? The form builder includes ready-to-use templates:

• Contact Form: Name, email, and message fields
• Sign Up: Full name, email, password, and terms checkbox
• Newsletter: Simple email subscription
• Feedback: Rating dropdown with comments

Load a template, tweak it to your needs, and export.

How It Works

1. Add fields: Click to add Input, Textarea, Select, Checkbox, or Dropzone fields
2. Configure: Set labels, placeholders, validation, and field-specific options
3. Customize form settings: Add a title, description, and choose whether to wrap in a Card
4. Copy the code: Click “Copy Code” and paste the generated .astro component into your project

The generated code uses Starwind UI components. If you haven’t installed them yet, the form builder shows you exactly which components you need.

Who Is This For?

• Astro developers who want shadcn/ui-style forms without the hassle
• Solo devs and indie hackers building landing pages and SaaS products
• Anyone who’d rather design visually than write boilerplate
