Comparison
Keylight vs Cryptlex — the Apple-native alternative
Cryptlex is a cross-platform licensing API with node-locked, floating, and hardware-bound models. Keylight is Apple-native: a Swift SDK, offline Ed25519 leases, and Stripe wired in.

Updated June 2026
Cryptlex is a solid cross-platform licensing engine — node-locked, floating, hardware-bound, the works. Keylight covers a narrower target deeper: Apple apps, native Swift SDK, Stripe wired in. If you’re shipping on the Mac, that focus does more for you than breadth. The honest comparison:
What Cryptlex gets right
Cryptlex is built for range. LexActivator runs across Windows, macOS, Linux, and more, and the licensing models go well past the basics — node-locked, floating and concurrent seats, hardware-bound licenses, on-prem deployment. If you need floating licenses for a team tool, or a license welded to specific hardware, Cryptlex does that out of the box.
That breadth is real, and for some products it’s exactly the requirement.
Where Keylight is different
Cryptlex gives you LexActivator — a C-based SDK you bridge into Swift. It works, but it’s not Swift, and the licensing state is still yours to manage.
Keylight is Swift end to end. The SDK is a state machine: checkOnLaunch(), then switch over .licensed, .trial, .expired, .invalid. Offline checks run on Ed25519 leases verified locally, with feature flags signed into the lease. On payments, a Stripe charge mints the license with no webhook code from you; other providers connect by webhook. You’re not bridging a cross-platform SDK into a Mac app — you’re using one built for it.
When Cryptlex is the better pick
Be honest about it. If you ship across Windows, Linux, and macOS from one codebase, Cryptlex’s cross-platform SDK fits where Keylight is focused today. If you need floating or concurrent seats, or licenses locked to hardware, that’s Cryptlex’s home turf, not Keylight’s. And if on-prem licensing is a hard requirement, Cryptlex has it.
Keylight is Apple-native first, and not stopping there — but if your need is floating seats or many platforms right now, Cryptlex is the straighter line.
Where Keylight fits
Building for the Mac and want native, not bridged? Keylight. Swift SDK, offline Ed25519 leases, Stripe-native minting, feature flags in the lease, multi-product and multi-tenant built in.
Plans start at $19/month, with a free tier. Test the whole flow before you pay.
