AI Vibe Coding: Building Local, Private Software for Business Use

What is AI Vibe Coding?

"Vibe coding" is a revolutionary approach to software development that leverages AI to transform natural language descriptions into functional code. Coined by AI researcher Andrej Karpathy in February 2025, this methodology allows business professionals to create software by simply describing what they want, rather than writing code line by line.

"There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It's possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good." — Andrej Karpathy

For businesses handling sensitive data, proprietary processes, or confidential information, traditional cloud-based AI coding assistants present significant privacy risks. This guide focuses specifically on implementing vibe coding workflows using local, private AI modelsto ensure your business logic, data, and intellectual property never leave your premises.
