Features and specs

What each product offers, as listed by its team.

Bulma 7 features
Keylight.dev 16 features
  • Simple and Elegant Design
    Bulma offers a clean, modern aesthetic that looks great out of the box. This eliminates much of the need for extensive customization to achieve a professional look.
  • Responsive Layouts
    Bulma is built with a flexible grid system that ensures your designs are responsive. This makes it straightforward to create web pages that look great on both desktop and mobile devices.
  • Ease of Use
    Bulma has a straightforward class-based syntax that is easy to understand and implement. This simplifies the development process, especially for newcomers.
  • BEM Methodology
    Bulma employs Block Element Modifier (BEM) methodology for CSS, which helps in writing clean, understandable, and scalable code.
  • No JavaScript Dependencies
    Bulma is purely a CSS framework, meaning it doesn't come bundled with JavaScript. This allows you to integrate it with any JavaScript framework of your choice, like React or Vue.js, without any conflicts.
  • Well-Documented
    The official Bulma website has extensive documentation, including examples and code snippets, which makes it easier to learn and implement.
  • Active Community
    Bulma has an active community of developers who contribute to its development and are available for support, which can be helpful when facing issues or needing guidance.

Possible disadvantages

  • Limited Customizability
    While Bulma is designed to be easy to use, its simplicity can sometimes limit your ability to customize components as deeply as you might be able to with other frameworks.
  • Lack of Components
    Bulma does not come with as many built-in components as some other CSS frameworks like Bootstrap. You might find yourself needing to create custom components for some features.
  • No JavaScript
    The lack of built-in JavaScript functionality means you will need to write or integrate JavaScript separately for more interactive elements, such as modals or carousels.
  • Performance Overhead
    Like most CSS frameworks, using Bulma can introduce some performance overhead due to unused CSS. You'll need to use a tool like PurgeCSS to remove unused styles for optimal performance.
  • Learning Curve
    Despite its simplicity, there can still be a learning curve for developers who are accustomed to other frameworks like Bootstrap or Tailwind CSS.
  • Small Community compared to Others
    While the community is active, it is smaller compared to more established frameworks like Bootstrap, potentially making it harder to find solutions to less common issues.
  • Semantic Class Names
    Bulma emphasizes semantic class names following the BEM methodology, which can be verbose and may require a change in practice for some developers.
  • 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

Questions & Answers

As answered by people managing Bulma 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
