Could API testing be easy?

Our mission is to help you test your APIs diligently and free up your developers' precious time.

How can we help?

Complete Web API Testing as a Service

Working with us will allow you to focus on software development and we'll make sure your Web API is continuously tested to the highest standard.

Continuous Intelligent Test Generation

Through our AI-based test case generation tools and expertise we can build scalable and comprehensive test cases that integrate with your CI/CD environment.​

Sandbox Environment Through Mocking

Simplify your development and testing by creating a fully sandboxed environment for running your code using our Mokk API. This will allow you to run your code as if it were executed in a production environment without having to worry about actually interacting with external services.

Test Quality Analytics

We offer consultation and metrics on your development processes and existing test cases to help you make your web API's quality as high as possible.


Having an OpenAPI document for your web API comes with a wide range of benefits. In addition, it makes integration with all of our tools a piece of cake. We can help you to develop and improve your OpenAPI documents.

Flexible Pricing​

We can tailor our service to meet your budget requirements while delivering cost efficient Web API testing. ​

Our service

1. Getting Started

Together we tailor the scope and the details of our service to best suit your web API development. We will also together make sure that your OpenAPI document is up to date and detailed enough so that we understand the requirements of your API.

2. Building Your Test Cases

Once everything is set up, we begin the continuous generation of test cases for your API. Our objective is to achieve maximum coverage using our comprehensive coverage metrics, to ensure that risks are reduced to the absolute minimum. 

3. Execution and Analytics​

We provide analytics on test suite quality, and give detailed reports if any failure in your API is encountered, to help you resolve faults as quickly as possible. We also provide foundation to seamlessly keep executing test cases for your existing functionalities by integrating with your CI/CD tools.

Other services​​

We also offer consultation on web API development and can help you to build your OpenAPI document from scratch.

What's OpenAPI?

OpenAPI Specification

Every API needs to be documented in one way or another, in order to communicate the functionality and interface of its components to end-users and between stakeholders. If you describe your API in a format that uses and conforms to the OpenAPI Specification, the resulting document is called an OpenAPI document.

Why use OpenAPI?

Describing your API through an OpenAPI document has a number of benefits:

  • The standard format makes your API documentation easy to understand for developers and end-users, seeing as many are already familiar with OpenAPI.
  • Automatically generate HTML pages for your documentation.
  • Make use of a wide range of specialized tools for improving ease of development.
  • Requirements in a formal format allow testers to design test cases without asking much time and insights from the developers.

Our story and mission

Mokkit was founded in late 2020, as it grew from a project between three passionate university students into a shared mission and a full-time business. Our vision is to bring the work of software developers to a next level of quality, effectiveness, and efficiency by providing them with innovative tools that augment and drive forward their development and testing. We strive to take full advantage of artificial intelligence and other advanced computing techniques to bring new ways of automation into the processes of software development. Joonas and Steyn, our first two co-founders, have extensive international academic background in advanced computing from Tsinghua University. Steyn researched test automation during his studies and subsequently graduated on this topic, publishing a paper on how to use state-of-the-art techniques from the field of deep reinforcement learning to automatically generate test data for web APIs. After graduation, Joonas and our third co-founder Antti joined to help evolve this project into the range of services that we offer today. Joonas specializes in human-computer interaction and blockchain, whereas Antti brings in business expertise with an MSc in business and administration from Aalto-University and practical experience from working in large organizations.
