Features and specs

What each product offers, as listed by its team.

BuildKit 5 features
Keylight.dev 16 features
  • Improved Caching
    BuildKit offers enhanced caching mechanisms that can significantly speed up the build process. It supports more efficient layer caching and is capable of parallelizing builds, allowing for faster image creation and reduced rebuild times.
  • Parallel Build Stages
    BuildKit's ability to parallelize the processing of build stages allows for more efficient use of resources, reducing the overall time needed to compile and assemble Docker images.
  • Flexible Syntax
    It supports advanced Dockerfile syntax, such as 'RUN --mount=type=cache', enabling more granular control over build operations, which can help optimize the build process and reduce size and time.
  • Security Improvements
    BuildKit adds security features like rootless builds and build secrets, allowing developers to create safer environments by limiting the need for superuser permissions and securely managing sensitive information during builds.
  • Reduced Build Context
    BuildKit can help minimize the build context sent to the Docker daemon, optimizing network usage and performance by only sending necessary files.

Possible disadvantages

  • Complexity
    For users familiar with the traditional Docker build system, the new features and functionalities of BuildKit, such as the advanced syntax and caching options, may introduce added complexity and a steeper learning curve.
  • Compatibility Issues
    Not all environments and Dockerfile features are fully compatible with BuildKit's advanced capabilities, which might require adjustments or limit its applicability in certain scenarios.
  • Resource Consumption
    Due to its parallel processing capabilities, BuildKit might consume more resources than traditional builds, potentially leading to increased CPU and memory usage.
  • Maturation Level
    As a relatively newer tool, BuildKit may still face occasional bugs and is in an ongoing state of development, which can impact stability and reliability for production environments.
  • 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.

Questions & Answers

As answered by people managing BuildKit 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

    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
