What is Interval?
Interval is a development platform that allows engineers to create full web applications for internal tools by writing only backend Node.js or Python code. It eliminates the need for frontend development by automatically generating UIs from simple SDK calls embedded within your business logic. This approach is ideal for developers who prefer coding business logic and dislike building user interfaces.
The platform integrates directly into your existing codebase, enabling the use of native language features like async/await, conditionals, and type safety. It provides a comprehensive component library for building forms, tables, and navigation, handling UI rendering, input validation, and network communication automatically. Interval is designed for rapid development and deployment of internal tools, making it suitable for startups and businesses looking to quickly build and scale custom operational applications.
