About Typescript and Keylight.dev

In their own words, as submitted to SaaSHub.

Typescript
Keylight.dev

No description of Typescript yet.

Keylight sits between your payment provider and your app. Licenses, activations, customers, and usage all live here. Switch providers, or run several, without shipping a new build.

Features and specs

What each product offers, as listed by its team.

Typescript 6 features
Keylight.dev 16 features
  • Static Typing
    Typescript adds optional static typing to JavaScript, which allows for early error detection and better IntelliSense support.
  • Improved Code Quality
    The type system encourages developers to write more robust and maintainable code by enforcing the definition of types.
  • Enhanced IDE Support
    Most modern IDEs offer better code navigation, autocompletion, and refactoring tools for TypeScript due to its type information.
  • Compatibility
    TypeScript is a superset of JavaScript, meaning existing JavaScript code is valid TypeScript, and it can interoperate with JavaScript libraries.
  • Scalability
    TypeScript’s type system makes it easier to manage and scale large codebases, improving team collaboration.
  • Community and Ecosystem
    A large and growing community provides a wealth of resources, libraries, and tools tailored to TypeScript development.

Possible disadvantages

  • Learning Curve
    Developers coming from a JavaScript background may need time to familiarize themselves with TypeScript concepts and syntax.
  • Build Step Requirement
    TypeScript code needs to be compiled to JavaScript, adding a build step to the development workflow.
  • Overhead
    The additional type annotations can lead to more verbose code, which may be seen as unnecessary overhead in smaller projects.
  • Tooling and Configuration
    Setting up TypeScript can sometimes be complex, requiring additional configuration for projects and integrations with various build tools.
  • Slower Iteration Speed
    The compilation process can slightly slow down the development cycle compared to working directly with JavaScript.
  • Strictness
    TypeScript’s strict type checks can sometimes be limiting, requiring workarounds or more complex type definitions.
  • 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.
  • Payment Provider Integrations
    Connect Stripe, Paddle, Lemon Squeezy, Polar, Gumroad, and other payment platforms.
  • Provider Independence
    Change payment providers or use multiple providers without rebuilding your app’s licensing system.
  • Swift SDK Integration
    Add licensing to macOS and iOS apps using a native Swift package.
  • Secure License Validation
    Protect license data with cryptographic signatures and tamper-resistant validation.
  • Trials and Free Tiers
    Configure trials, free plans, fallbacks, and upgrade paths without building custom logic.
  • Customer Dashboard
    View licenses, customers, devices, activations, plans, and access status in one place.
  • License Analytics
    Track activations, active licenses, usage, and customer activity.
  • Key Rotation
    Rotate SDK signing keys without breaking older application versions.
  • Webhook Synchronization
    Convert payment, renewal, refund, cancellation, and subscription events into license updates.
  • Device-Bound Storage
    Store license data securely on the customer’s device without unnecessary Keychain prompts.
  • REST API
    Connect custom backends, checkout systems, and internal tools to Keylight.
  • Agentic Orchestration
    CLI usable by AI Agents to run the whole setup and more.

Questions & Answers

As answered by people managing Typescript 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
