I built Diffract because every time I needed to compare two files I was choosing between an ugly terminal diff, a diff view buried three menus deep in my editor, or a $60 tool that felt like it was designed in 2008.
I wanted something fast and good-looking that opens instantly, handles real-world files (generally code, but also Word docs, spreadsheets, PDFs, whole directories, binaries), and doesn't nag me with a subscription. It's a one-time purchase with a generous free tier and a 7-day Pro trial.
Happy to answer any questions about how it works under the hood.
