Questions & Answers

As answered by people managing HetrixTools and Keylight.dev.

What makes your product unique?

Keylight.dev's answer:

Keylight keeps app licensing separate from payments. You can use Stripe, Paddle, Lemon Squeezy, Polar, Gumroad, or your own checkout without tying your app to one provider.

It handles license keys, device activations, trials, free tiers, offline access, grace periods, and signed license state through one SDK.

Why should a person choose your product over its competitors?

Keylight.dev's answer:

My goal is to make all apps work with Keylight. So all of your licenses, from any types of apps, is going through Keylight for analytics, customer portal, support, ...

Most licensing tools are bundled into a payment provider. Keylight is built as an independent licensing layer.

That means you can change payment providers, sell through multiple platforms, or change your pricing model without rebuilding licensing inside your app.

It also gives developers a ready-made SDK and dashboard instead of requiring them to build and maintain their own licensing backend.

How would you describe the primary audience of your product?

Keylight.dev's answer:

Keylight is primarily built for independent developers and software companies selling apps directly to customers.

Its main audience includes:

macOS and iOS developers Web app and SaaS developers Developers selling outside app stores Teams migrating from a payment provider’s built-in licensing Developers who need trials, device limits, offline access, and license analytics

What's the story behind your product?

Keylight.dev's answer:

Keylight started because I kept rebuilding the same licensing systems for different apps: license keys, trials, activations, offline access, device changes, and all the edge cases that come with them.

I also did not want licensing to be controlled by whichever payment provider an app happened to use.

So I built Keylight as a standalone layer between the app and the payment provider. Payment platforms send events to Keylight, and the app receives one consistent license state through the SDK.

Who are some of the biggest customers of your product?

Keylight.dev's answer:

That's confidential.

Which are the primary technologies used for building your product?

Keylight.dev's answer:

Swift and Swift Package Manager for the Apple SDK Rust SDK / JS SDK / C# SDK / C++ SDK TypeScript React Next.js Stripe Connect and payment-provider webhooks Cryptographic signatures for secure, offline-capable licenses REST APIs for application and provider integrations

  • How offline license activation actually works
    You don't want to hand-roll Ed25519 and lease parsing. Most licensing SDKs hide this behind a couple of calls. With Keylight, for example, the offline path collapses to: activate once, then a local checkOnLaunch() that verifies the lease... - Source: dev.to / 3 months ago
