If you've ever wrestled with writing OpenAPI specifications manually in YAML, you know the pain — indentation errors, complex schemas, forgotten parameters, and endless scrolling.
We get it. That's why we built YAML Studio — a form-based OpenAPI YAML Generator that helps you create, edit, and preview OpenAPI 3.0.0 specs without writing a single line of YAML manually.
🛠 What Is YAML Studio?
YAML Studio is a browser-based tool to generate OpenAPI 3.0.0 specs through an intuitive drag-and-drop form builder, complete with live preview and import/export options.
Whether you're documenting a new API or cleaning up a legacy spec, YAML Studio makes your workflow faster, cleaner, and far less frustrating.
✨ Features
✅ OpenAPI 3.0.0 Support
Supports all core components of OpenAPI 3.0.0, including:
Paths and methods
Parameters and request bodies
Responses and status codes
Schemas and definitions
Security schemes (OAuth2, bearerAuth, etc.)
🧱 Form-Based Interface
No YAML knowledge required. Just fill in forms — we handle the structure and indentation.
🔍 Live YAML Preview
Every change you make in the UI is instantly reflected in a real-time YAML preview panel. Copy/paste-ready anytime.
📥 Import Existing YAML
Already have a spec? Paste it into YAML Studio to visualize and edit it through the form UI.
📤 Export YAML
Generate clean, valid OpenAPI YAML you can download or copy directly to your repo.
