🧠 Build Your Own Local AI Coding Agent (Like Cursor) — No Magic, Just Python
What if you could talk to a terminal agent that writes code, edits files, and follows instructions — all locally?
Meet VibeCode, the structured, tool-using coding assistant you can build in under 100 lines of Python.Nonmembers, click here
Why I Built This: A Developer’s Dream
We’ve all used ChatGPT to write snippets of code. But I wanted more — not just a chatbot that suggests code, but an assistant that actually writes files, executes commands, and structures code into projects — just like a real pair programmer would.
So I built VibeCode — a local agent that works like an IDE companion. It’s not a SaaS product. It’s not cloud-dependent. It’s yours, running on your terminal, powered by GPT-4.
Here’s the best part: you can build it too. In this guide, I’ll walk you through the full architecture, prompt strategy, and the exact Python code I used.
What is VibeCode?
VibeCode is a terminal-based coding agent powered by OpenAI’s GPT-4 that:
- Follows structured agent steps (
plan ➜ action ➜ observe ➜ output) - Writes or edits code files on your machine
- Executes shell commands
- Always uses multiline, clean code formatting
- Responds in pure JSON for easy parsing and automation
