Simulate real-world scenarios with intelligent mock data. From basic CRUD to complex error states, ensure your API handling is rock-solid. Reduce production incidents by up to 80% through comprehensive testing.

Data Science Ready

Supercharge AI/ML Development

Generate massive, structured datasets for AI training and testing. Create edge cases, anomalies, and perfectly-labeled data. Cut data preparation time by 70% while improving model accuracy by up to 40%.

How it works

01

Define your data model

Start by defining your custom data model using our intuitive interface. Specify the properties, data types, and any constraints you need for your API endpoints or applications. You can also import your existing Open API schema to automatically create the data model.

02

Map endpoint to your model

Once your data model is defined, create an endpoint and map it to your data model and you're good to go. By making an API request to the endpoint, realistic mock data that simulates that of real-world and that conforms to your model will be returned as a response data.

03

Integrate and Test

With the models and API endpoints ready, you can seamlessly integrate it into your APIs or applications. You can call the APIs from your application to load your data, whether you are prototyping, implementing and testing a new feature or testing an integration of a third-party API.

    Test with confidence using our enterprise-grade mock data. From basic CRUD operations to complex error scenarios, ensure your application handles every case flawlessly before going live.

Frequently Asked Questions

Dynamic mock data generation is the process of creating realistic data that mimics real-world scenarios for APIs and applications. It allows developers to generate custom data models and populate them with dynamic data, saving time and effort in manual data creation or waiting to connect to a backend to get real data from the database when it's not yet ready.

Dynamic mock data has various use cases. You can use it for prototyping frontend applications, integration testing, user acceptance testing, load testing, frontend development, demo data generation, and more. It provides you with realistic data to ensure your software performs as expected. You can easily switch to your production server base URL when moving into production.

Yes! Our application supports the import of OpenAPI schemas. With a click of a button, your whole API paths and definitions are imported and ready to use!

Our application offers extensive customization options. You can define the data model with properties, data types, and constraints specific to your needs. Additionally, you have control over the quantity of generated data, error scenario simulation configuration, allowing you to simulate various data and API calls scenarios.

Absolutely! Our data generation engine creates dynamic mock data that closely resembles real-world data. You can generate data with diverse values and locales, ensuring comprehensive testing and accurate representation of your production environment.

While our application is primarily designed for testing and development purposes, you can certainly use the generated mock data in your production environment during early stages or for non-sensitive data scenarios. Exercise caution and ensure data privacy and security measures are in place.

Absolutely! Our application facilitates collaboration between team members. Backend engineers can share endpoint schemas with frontend developers, ensuring seamless integration and alignment throughout the development process.

Here's what developers are saying about MockAPI!

David Chen

Frontend Developer at TechStart

"MockAPI has been a game-changer for our frontend team. We used to wait days for backend endpoints to be ready, but now we can prototype and test features immediately. The realistic data generation is spot-on - it actually feels like we're working with production data!"

Sarah Martinez

Full Stack Developer at CloudScale

"The OpenAPI import feature saved me hours of work. I just imported our existing schema, and boom - instant mock endpoints! The error simulation is particularly useful for testing edge cases. This tool has become an essential part of our development workflow."

Michael Patel

Lead Developer at DataFlow

"As a team lead, I appreciate how MockAPI has improved our development speed. The realistic data generation helps us catch edge cases early, and the ability to share endpoints across the team keeps everyone in sync. Worth every penny!"

Emma Wilson

API Developer at FinTech Solutions

"I was skeptical at first, but MockAPI exceeded my expectations. The data generation is incredibly sophisticated - it even handles complex relationships between models. Perfect for developing and testing financial APIs where data accuracy is crucial."

Alex Thompson

Senior Developer at HealthTech

"Working in healthcare tech, we need realistic but anonymized data for testing. MockAPI's customizable data types and constraints help us generate HIPAA-compliant test data. The error simulation features are particularly useful for testing our error handling."
