CodePrep ships open-source AI mock interviewer
CodePrep is an open-source Python app that simulates coding interviews with an AI interviewer, built-in code execution, voice mode, and structured feedback. It ships 132+ real-world problems and keeps sessions, history, and code local, with OpenAI handling only the messages and code you send.
CodePrep’s real strength is the feedback loop, not the problem count. It makes candidates explain, code, get pushed back on, and receive a debrief that feels much closer to a real screen than a LeetCode clone.
- –Voice mode trains the communication layer most prep tools ignore.
- –The scenario-based problem library is better practice for real interviews than random puzzle grinding.
- –Open source and local-first storage make the tool easier to audit, tweak, or self-host.
- –The tradeoff is real: it still needs a paid OpenAI API key, and the runtime is Python-only.
