The review loop is free. Pro is $10 a year.
The whole diff workflow ships in Free and stays there. Pro buys the comforts you'll want once Diffr is a daily habit: your themes, your notes, your pinned repos. One price, stated once.

Questions
Will the free version stay free?
Yes. The full review workflow is free and stays free: working tree, commit ranges, split and unified, keyboard nav, watch mode, Tokyo Night. It's the product that spreads, so we're not going to gate it later.
How many machines does one license cover?
All of them. One license is yours across every Mac you own, and it works offline — no seat counting, no activation server.
What does the $10 launch price get me?
The launch price is locked for the first 1,000 licenses. You keep $10/year for as long as you renew; after the first 1,000, new licenses are $20/year.
What if I want a refund?
Email within 30 days for a full refund. No questions, no form. If Diffr didn't earn a spot in your daily loop, you shouldn't pay for it.
Do I need an account?
No. Download, open a repo, review. Pro is a license key you paste into Settings → License. Nothing to sign up for.
