Features and specs

What each product offers, as listed by its team.

Babel 5 features
Keylight.dev 16 features
  • JavaScript Version Compatibility
    Babel allows developers to write code using the latest JavaScript features and syntax, and transpile it into a version of JavaScript that can run on older browsers. This ensures greater compatibility across different environments.
  • Future-Proof Code
    With Babel, developers can start using upcoming JavaScript features today. This means that codebases can stay modern and developers can take advantage of new functionalities without waiting for full browser support.
  • Ecosystem and Plugins
    Babel has a rich ecosystem of plugins and presets that can extend its capabilities, making it highly adaptable to different project needs. This modularity allows for customization and enhancement of the build process.
  • Integration with Modern Development Tools
    Babel integrates well with various development tools such as Webpack, making it easier to include in existing build processes and workflows. This helps streamline development and maintain efficient workflows.
  • Community and Support
    Babel has a large and active community, which means extensive documentation, tutorials, and support forums. This can be particularly useful for troubleshooting and staying updated with best practices.

Possible disadvantages

  • Performance Overhead
    Transpiling code with Babel introduces a performance overhead during the build process. This can slow down development workflows, especially for large codebases with many files.
  • Configuration Complexity
    Setting up Babel can be complex, particularly for beginners. The numerous options and plugins available can sometimes be overwhelming and require significant time to configure correctly.
  • Source Map Issues
    Generating accurate source maps can sometimes be tricky with Babel, leading to difficulties in debugging. Misconfigured source maps can make it harder to track down issues within the original source code.
  • Dependency Bloat
    Including Babel in a project can add a significant number of dependencies. This dependency bloat can increase the size of the project and potentially introduce maintenance challenges or security vulnerabilities.
  • Learning Curve
    There is a learning curve associated with Babel, especially for developers who are new to modern JavaScript tooling. Understanding how Babel works and how to effectively use its features can take time and effort.
  • 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 Babel 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
