Sphere Engine

Plug coding tasks directly into your product and let users run programs without leaving your app. Start by wiring the remote execution API into your backend: choose a language from 80+ options, set time and memory limits, then send code with optional stdin. Receive output, compile errors, and resource usage via webhook or polling, and render the results in your UI. Use the sandbox to isolate runs, whitelist libraries your audience needs, and log each submission for auditing. If you offer multi-language challenges, detect the user’s selection and route it to the correct runtime. For performance, cache runtime metadata and prewarm popular environments.

Build assessments the same way you build content. Author a problem statement, attach starter files, and define test cases: examples users can see, private checks for scoring, and stress tests for edge conditions. Set weights and partial credit rules, or craft a custom scoring formula for your use case (accuracy-first, speed-first, or hybrid). Randomize inputs to reduce hardcoding. Enable real-time rankings for contests, then export detailed reports that show pass rates, runtime, memory, and attempts per task. Track progress automatically across modules so instructors and recruiters can compare cohorts, identify skill gaps, and surface candidates who consistently pass on the first try.

Embed an online IDE wherever learners read instructions—course pages, docs, or product tours. Preload dependencies, pin versions, and provide run/submit buttons tied to your problem bank. Guide users with inline hints, attach reference solutions for reviewers, and schedule challenge releases for classes or hiring rounds. Manage the entire lifecycle in a central challenge hub: draft, review, publish, archive. Capture issue reports from users right from the editor, link them to a task, and re-run failing submissions to validate fixes.

Operate at scale with clear workflows. Assign roles (author, reviewer, proctor), define review gates, and monitor test operations from a single dashboard. Spin up large events—hackathons, bootcamps, or campus drives—with live leaderboards and throttled concurrency to control cost. Plug into your stack with REST, SDKs, and webhooks; feed results into ATS, LMS, or BI tools. Support learners who prefer Java, Python, C++, or dozens of other languages without maintaining compilers yourself. Rely on developer-focused docs and examples to accelerate integration and keep maintenance low as your programs grow.
