Frequently Asked Questions


How do you prepare my pricing offer?

There's no single parameter that we base the offer on. We look at each case individually. When preparing an offer we consider such factors as your project scope, number of your students/candidates, the expected number of submissions to our APIs , the support you require, etc.

We'll do our best so that the offer you receive works for you, whether you're a small business or an enterprise.

Can I use Sphere Engine for free?

Our product is purely commercial. What we offer to the community is using one of our free services: Sphere Online Judge (a platform designed to share, discuss and solve programming challenges) or Ideone (an online compiler and debugging tool which allows you to compile source code and execute it online in more than 80 programming languages).

Do you offer annual plans?

We're pretty flexible when it comes to payment - annual and quarterly plans are available.

What forms of payment do you accept?

We accept all major credit cards: Visa, Mastercard, American Express, Discover. You can also use PayPal. For additional payment options, like wire transfer or traditional banking, please contact us.
