differing is a stand-alone code review tool. I use it to review changes from LLM-based coding agents. It borrows from work I did on sketch.dev's code review tool.

This is largely vibe-coded, but I've reviewed it.

The implementation uses Monaco's diff view, and allows you to accumulate comments which you can paste into your favorite agent.

curl -Lo differing "https://github.com/philz/differing/releases/latest/download/differing_$(uname -s | tr '[:upper:]' '[:lower:]')_$(uname -m | sed 's/x86_64/amd64/;s/aarch64/arm64/')" && chmod +x differing

The binaries are on the releases page.

brew install philz/tap/differing

You'll need Go and Node.

git clone https://github.com/philz/differing.git
cd differing
make

New releases are automatically created on every commit to main. Versions follow the pattern v0.0.N where N is the total commit count.
