Questions
Is Pinspect a CSS Peeper alternative?
Yes. Pinspect covers the same everyday job (seeing fonts, colors and spacing and copying CSS) with a useful free tier, no injected pop-ups, no tracking, and a one-time Pro price instead of a subscription.
What does Pinspect send over the network?
Nothing, except checking your Pro license key with Gumroad when you activate it and at most once a week after that. There are no analytics and no remote code.
Which permissions does it need?
Only activeTab, scripting and storage. It runs on a page only after you click its icon there.
Is Pro a subscription?
No. Pro is a one-time $12 purchase with a license key. You can ask for a refund within 30 days.
