CodePrep ships open-source AI mock interviewer

ANNOUNCEMENTPRODUCTGITHUBPRODUCT HUNT

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.

// ANALYSIS

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.
