Browser-based coding environment with autocomplete, test execution, and multi-language support — no setup required for candidates or admins.
Browser controls, screen monitoring, and real-time anomaly flagging ensure total assessment integrity.
Handles high concurrency with performance consistency across all global regions and low-bandwidth environments.
First impressions matter. Prelim's browser-based IDE is built from the ground up for the assessment context — fast, distraction-free, and functionally rich enough to feel like a real development environment.
Candidates can choose their preferred language, use their preferred keyboard shortcuts, and run tests in real time — all without installing anything. For assessors, every keystroke and paste event is logged for integrity analysis.
A coding environment serious developers respect — with assessment controls built in.
Code runs in an isolated sandbox in under 200ms — candidates get real-time feedback without waiting on compilers.
Tab-switch alerts, paste logging, and optional webcam proctoring work silently in the background.
Pre-load starter code, test suites, and README instructions to mirror your real repository structure.
A polished, professional coding experience from first prompt to final submission.
Customise the coding environment to match your stack and attract serious talent.
