Keylight - Issue licenses, collect payments, ship your apps.

by•
Keylight is a licensing layer built specifically for Mac app developers. Unlike Paddle, Lemon Squeezy, or generic payment tools where licensing is secondary, Keylight focuses on license keys, activations, device limits, offline access, upgrades, renewals, subscriptions, analytics, and a Swift SDK. It helps indie devs sell outside the App Store with more control and less platform lock-in.

Hey everyone — I built Keylight because I kept seeing the same problem with indie Mac apps. Most developers don’t want to spend weeks building licensing, activations, device limits, upgrades, renewals, customer portals, and analytics. But the existing options usually treat licensing as a side feature attached to payments. Keylight is different: it’s a licensing layer first. It helps Mac developers sell outside the App Store, issue license keys, connect payments from tools like Stripe, Paddle, Lemon Squeezy, Gumroad, Polar, Shopify, and more, and ship with a Swift SDK built for real app distribution. The goal is simple: give indie developers more control, better visibility, and less platform lock-in. Would love your feedback, especially if you’ve shipped a Mac app before or struggled with licensing.
