What it does
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.
Add license keys to your app in minutes. Swift-first, with Rust and JavaScript SDKs — offline Ed25519 verification, device limits, trials, and Stripe-native billing. No licensing backend to build.
Keylight sits between your payment provider and your app. Licenses, activations, customers and usage live here. Switch providers, or run several, without shipping a new build. Every license, device, and payment for one customer — the whole picture in one view. Free or paid, everyone lands in one list: keys, devices, and history right there. Lost keys, new laptops, plan changes: users sort it out on their own page, not in your inbox. Paddle, Lemon Squeezy, Polar and Gumroad help you sell software. Keylight decides who can use what, on which device, and for how long . Most apps need both. Keylight is the licensing half. Comparing dedicated licensing tools?

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
