Automated IT skills assessment

Our technology makes it possible to test the coding skills of your users automatically and online.

Create IT skill tests & automatically evaluate users' solutions. Choose from 10+ different testing formulas (or design your own!).

There are no limits on the number of programming problems nor on the number of users. Scalability is what we believe in. The number of possible submissions depends on your chosen subscription plan.

CMS for managing problems

A user-friendly panel for uploading and testing programming problems, accompanied by a pool of ready-made problems which may serve as inspiration for your own team of Problem Setters.

The system allows you to create programming problems with up to a 100 testcases and to choose from many different ways in which the submitted code will be evaluated, ranging from a simple binary "Accepted"/"Wrong Answer" status to a detailed point scale.

You can also take advantage of the flexibility of our system to set your own customized testing formulas.

Powerful reports

Each submission generates a full performance report, which characterizes the program's performance in all the testcases and information about the usage of processor time, memory, and any potential errors.

The system supports the real-time ranking of many users, automatically generating lists of top scorers. This feature is designed with programming contest organizers in mind.

It is also possible to create your own, fully customized testing & ranking formulas and to add numerous testcases for each problem. The system supports both simple, binary testing formulas, such as "Accepted"/"Wrong Answer", and more sophisticated point scales or evaluation performed by external software.

Easy-to-use API and integration

We make our API available in the most popular formats, such as SOAP, Json, and REST. Feel free to choose the most suitable type of integration.

When it comes to problem setting and content management, we provide an easy-to-use CMS, where you can upload & test programming problems, before making them available to your end users through the API.

Our experienced support team is always willing to help you with system integration, test design, and community building.
