Get a working Mock API endpoints in seconds. No servers to configure, no databases to set up. Just describe your needs and start coding.

Best way to start your project
MocklyAPI helps you create simple, reliable mock API endpoints when your backend isn't ready or when you need predictable data for development and testing. You can generate realistic mock data using clear prompts, return fresh randomized responses on every request, and control access with public or private endpoints. With support for response delays and custom data, MocklyAPI fits naturally into your development workflow making it easier to prototype, test, and iterate without unnecessary setup or infrastructure.

MocklyAPI combines AI-powered data generation with a simple, intuitive interface. Our AI assistant helps you create realistic, contextually aware datasets without manual data entry. Plus, you get powerful features like filtering, ordering, and nested object support right out of the box.
Yes! You have complete flexibility. Use the AI assistant to generate initial datasets, then customize them to your needs. Or skip the AI entirely and paste your own JSON data. You can also refine AI-generated data through conversation to get exactly what you need.
MocklyAPI is currently free during early access. You get 10 mock APIs per project, 50,000 requests per month, 100 requests per minute rate limit, and up to 50,000 characters per response. We'll announce pricing plans before the official launch, with advance notice for early access users.
Absolutely! MocklyAPI supports advanced querying with filters, ordering (ascending/descending), and limiting results. You can filter by any field including nested objects using dot notation, making it easy to test different data scenarios without creating multiple endpoints.
Yes! Configure response delays (0-30 seconds) to test loading states and slow networks. Set custom HTTP status codes (200, 400, 500) to test error handling. These features help you build resilient applications without needing a real backend.
Currently, we support JSON format, which covers most modern API needs. We're planning to add XML, HTML, and plain text formats in future updates based on user feedback.
Yes! You can choose between public endpoints (no authentication required) and private endpoints (protected with authentication tokens). Private endpoints require a valid auth token via query parameter or header, ensuring your mock data stays secure.
No! Only successful requests (2xx status codes) count toward your monthly quota. Unauthorized requests (401), rate-limited requests (429), and server errors don't consume your allocation, so you can test freely without worrying about hitting limits.
MocklyAPI is designed for development, testing, and prototyping. While the service is reliable during early access, we recommend transitioning to a production API before launch. It's perfect for frontend development, demo applications, and proof-of-concepts.
We'd love to hear from you! Since we're in early access, your feedback directly shapes the product. Use the thumbs down button in the dashboard, email us at support@mocklyapi.com, or share feature requests through our feedback form. Early access users help us build the best mock API tool possible.
