Grav 7 features

  • Flat-file architecture
    Grav is a flat-file CMS, which means it doesn't rely on a database. It stores content in files and folders, making it easy to manage, version control, and requiring less server resources.
  • Performance
    Without a database layer, Grav can deliver faster load times and better performance, especially critical for high traffic websites.
  • Flexibility and Customization
    Grav is highly customizable with a flexible API that allows developers to build and extend functionalities effortlessly.
  • Ease of Installation and Setup
    Grav boasts a simple setup process. You can get started quickly without complex configurations, making it accessible for both developers and non-developers.
  • Strong Community and Documentation
    Grav has an active community that provides robust support. The extensive documentation helps users get through the learning curve quickly.
  • Security
    Flat-file systems like Grav are typically less vulnerable to common database-related security issues like SQL injection attacks.
  • Themes and Plugins
    Grav offers a variety of themes and plugins that enhance its functionality, allowing users to add new features without extensive coding.

Possible disadvantages

  • Learning Curve
    Although Grav has good documentation, it can have a steeper learning curve for those unfamiliar with flat-file CMSs or who come from traditional database-driven CMS backgrounds.
  • Not Ideal for Large-scale Projects
    Flat-file systems can become cumbersome to manage as the scale of content grows, making Grav less suitable for large-scale websites with extensive content.
  • Limited Third-party Integrations
    Grav may not have as many third-party integrations available compared to more established CMS platforms like WordPress, potentially limiting its functionality.
  • Hosting Requirements
    While Grav doesn't need a database, it still requires a hosting environment that supports PHP. Some shared hosting services may not offer the ideal settings out-of-the-box.
  • Smaller Ecosystem
    Grav has a smaller user base compared to more established CMSs, which can mean fewer community-created plugins and themes.
  • No Default GUI for Content Editing
    Grav does not natively offer a graphical user interface for content editing, which can be a drawback for non-technical users. Though Admin Panel plugin exists, it is not default.
  • 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.

Questions & Answers

As answered by people managing Grav 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
