How to Review Code with Ollama on Mac
Run fully private, offline code reviews on your Mac using Ollama. Your source code never leaves your machine — perfect for proprietary codebases, air-gapped environments, and developers who value complete data sovereignty.
Why This Combination Works
Ollama runs AI models entirely on your Mac, meaning your source code never leaves your device. This is critical for proprietary or sensitive codebases where sending code to a cloud API isn't acceptable. With Apple Silicon's powerful Neural Engine, local models run surprisingly fast. You also pay zero per-request costs.
Recommended Model
Qwen 2.5 Coder 32B — purpose-built for code understanding, this model delivers impressive code review quality locally while running efficiently on M-series Macs with 32GB+ RAM.
Example Prompt
Review this code for bugs, performance issues, and style violations. Focus on logic correctness and potential null pointer issues. Keep suggestions concise and actionable.
Setup Steps
Download Echoo
Install Echoo from echoo.ai and launch it from your menu bar. The app runs quietly in the background, ready whenever you need it.
Install Ollama and pull a model
Download Ollama from ollama.com, then run "ollama pull qwen2.5-coder:32b" in Terminal. Ensure your Mac has at least 32GB RAM for optimal performance with this model.
Set up a Code Review command
Create a custom command in Echoo pointing to your Ollama instance. Use a focused system prompt — local models work best with clear, concise instructions.
Review code with a shortcut
Select code, press your shortcut, and Echoo routes the request to Ollama running locally. Reviews typically take 5–15 seconds depending on your hardware.
Frequently Asked Questions
For the Qwen 2.5 Coder 32B model, you need an Apple Silicon Mac (M1 or later) with at least 32GB of unified memory. Smaller models like Qwen 2.5 Coder 7B work on 16GB Macs but with reduced quality.
For common languages and patterns, Qwen 2.5 Coder 32B is remarkably close to cloud models. It may miss some edge cases that GPT-4o or Claude would catch, but the privacy trade-off is worth it for many teams.
Yes. Once you've downloaded the model, Ollama runs completely offline. This makes it ideal for air-gapped environments, travel, or anywhere with unreliable connectivity.
