What is SDET Code?

SDET Code is a hands-on practice platform for QA Engineers and SDETs. Write real pytest tests that hunt and kill code mutations — bugs deliberately injected into programs. With 339 graded challenges across 6 real-world domains (fintech, commerce, SaaS, platform, content, common), AI-powered coaching, and a browser-based Python runtime via WebAssembly, no setup is required. Track your Kill Ratio, earn career ranks from Trainee to Sentinel, and compare your bug-finding skills against GPT-5 models. Free to start, no credit card needed.
