Cojudge is an offline-first coding practice judge covering the Blind 75 and NeetCode 150 problem sets, with Docker-sandboxed execution across seven languages, custom test cases, and a built-in debugger. It deliberately has no discussion forum, no LLM assistant, and no internet requirement once installed.
