How to Automate Code Reviews with Local LLMs (No API Keys Required)

I got tired of waiting for PR reviews. My team's across three timezones, and sometimes a simple "is this logic right?" question sits for 12 hours. So I built an automated pre-commit code review using Ollama and git hooks. It runs entirely local—no API keys, no usage limits, no sending proprietary code to external servers. Here's the setup that's been running on my machine for two months. Why Local LLMs for Code Review? Cloud APIs are great until: You're working with sensitive code You hit rate limits at 2 AM debugging Your company's security policy says no external AI You don't want to pay per token for every commit Running local LLMs for coding tasks solves all of this. The quality isn't GPT-4, but for catching obvious bugs and suggesting improvements? It's surprisingly good. What You'll Need Ollama - Dead simple local LLM runner A decent GPU - 8GB VRAM minimum, 16GB recommended Git - Obviously 10 minutes - That's genuinely it Step 1: Install Ollama # Linux/WSL curl -fsSL https://olla
