Features and specs

What each product offers, as listed by its team.

Hammer.js 4 features
Keylight.dev 16 features
  • Touch Gesture Support
    Hammer.js is specifically designed to handle touch gestures, making it easier to implement complex multi-touch interactions like swipes, pinches, and rotations without relying on native touch events.
  • Lightweight
    The library is relatively small in size, which means it won't significantly increase the load time or bandwidth usage of web applications.
  • Ease of Use
    Hammer.js provides a simple API that abstracts away the complexity of different input types, allowing developers to add gesture support with minimal setup and code.
  • Cross-Platform Compatibility
    Hammer.js is designed to work consistently across various platforms and devices, ensuring that touch interactions behave similarly on different browsers and operating systems.

Possible disadvantages

  • Limited to Gestures
    While Hammer.js excels at gesture recognition, it is not a comprehensive solution for all touch events, so developers might need to use additional libraries or custom code for other touch features.
  • Performance Overheads
    In complex applications with many touch interactions, Hammer.js could introduce performance overhead, potentially leading to slower touch responses if not optimized properly.
  • Maintenance and Updates
    Hammer.js is not as actively maintained as some other libraries, which could result in longer periods without updates or fixes for emerging issues and compatibility challenges.
  • Dependence on jQuery (for some features)
    Some implementations or extended features of Hammer.js may require jQuery, which can be a disadvantage for projects that do not use jQuery or aim to minimize external dependencies.
  • License Management
    Create, validate, revoke, and manage software licenses from one dashboard.
  • Device Activations
    Limit how many devices can use a license and manage individual activations.
  • Offline Access
    Keep apps working securely without a constant internet connection using signed offline leases.
  • License States
    Handle trial, free, paid, expired, limited, and grace-period access through one consistent state.

    View licenses, customers, devices, activations, plans, and access status in one place.
  • License Analytics

Questions & Answers

As answered by people managing Hammer.js 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
