What Sphere Engine is
Sphere Engine is a paid set of APIs and software components for building coding assessments and online code-execution environments. Its Compilers module runs programs in more than 80 languages and can return execution time, memory use, exit signals, output, runtime errors, warnings, and compilation errors. Problems lets organizations create and test programming challenges, use ready-made problems for ideas, produce performance reports and real-time rankings, and customize testing and ranking formulas. Containers executes complex, multi-component projects and provides an embeddable online IDE for teaching and assessing coding with Linux-based technologies. Described scenarios include web, desktop, mobile, and console applications, testing, artificial intelligence, machine learning, and data science. REST APIs, webhooks, and widgets support application integration. Deployments can use Sphere Engine cloud infrastructure or an on-premise version, with custom execution parameters and execution-box counts. A fully functional 14-day trial is available without a credit card. Enterprise subscriptions include 24/7 support, an SLA, and custom feature development.
