Features and specs

What each product offers, as listed by its team.

Koa.js 5 features
PermitCore.dev 6 features
  • Lightweight
    Koa.js is designed to be a smaller, more expressive, and more robust foundation for web applications and APIs, minimizing the middleware interface.
  • Modern JavaScript
    Koa.js is built using modern JavaScript features, such as async/await, making the code more readable and easier to maintain.
  • Modularity
    Koa provides a suite of methods that make writing servers fast and enjoyable. Additionally, it doesn't come with middleware, so you can pick and choose the pieces you need, resulting in a more tailored application.
  • Error Handling
    Koa has improved error handling mechanisms compared to some other Node.js frameworks, streamlining the process of catching and managing errors.
  • Performance
    Due to its lightweight nature and the absence of bundled middleware, Koa generally has better performance metrics in terms of speed and memory consumption.

Possible disadvantages

  • Steeper Learning Curve
    Koa's minimalist approach and reliance on new JavaScript syntax can be challenging for beginners or those who are more accustomed to frameworks like Express.js.
  • Lack of Middleware
    Although its lack of built-in middleware promotes modularity and flexibility, it also means that developers have to spend additional time incorporating necessary middleware components.
  • Smaller Ecosystem
    Koa has a smaller ecosystem compared to more mature Node.js frameworks like Express.js. This could result in less community support and fewer third-party plugins and extensions.
  • Less Documentation
    While Koa.js has its official documentation, there are fewer tutorials, guides, and comprehensive resources available compared to some other more established frameworks.
  • Compatibility Issues
    Given that Koa.js leverages modern JavaScript features, it may not be compatible with all Node.js versions or legacy systems, necessitating careful consideration during adoption.
  • Complete licensing lifecycle
    Create, implement, and sell software licenses from one platform.
  • Store 2.0 branded storefront
    Responsive visual merchandising, trials, bundles, scheduled discounts, Stripe checkout, customer accounts, automatic license delivery, and 0% PermitCore sales commission.
  • Flexible license models
    Online, offline, floating, node-locked, subscription, metered, and perpetual licensing.
  • Reseller Program
    Give resellers a dedicated dashboard to track customers, sales, and earnings.
  • Customer Portal
    Customers can view and validate licenses, manage devices, and handle access without contacting the vendor.
  • REST API and eight SDKs
    Integrate licensing with .NET, Node.js, Python, Java, C++, PHP, Go, and Unity.

Questions & Answers

As answered by people managing Koa.js and PermitCore.dev.

What makes your product unique?

PermitCore.dev's answer:

PermitCore gives software teams one complete path from creating licenses to implementing licensing and selling their product. Developers can generate and manage licenses, integrate them through the REST API or SDKs, and sell licenses directly through a built-in Store without paying PermitCore a commission. It also supports online and offline licensing, floating and node-locked licenses, device limits, entitlements, subscriptions, customer and reseller portals, and Stripe automation. Underneath that workflow is a security model where license keys are encrypted in the browser before storage and usable keys are never persisted in plaintext. A permanent free plan is available for indie developers.

Why should a person choose your product over its competitors?

PermitCore.dev's answer:

Choose PermitCore when you want one platform for the full licensing lifecycle instead of several disconnected tools. You can create and manage licenses, implement licensing through the REST API or SDKs, and sell licenses directly through a built-in Store. PermitCore takes no commission on those software sales. It also covers device management, online and offline use, floating seats, entitlements, subscriptions, customer and reseller portals, and Stripe automation. Browser-side encryption keeps usable license keys out of plaintext storage. PermitCore is EU-hosted, supports Enterprise self-hosting, includes a permanent free plan, and gives every paid plan a three-month free trial.

How would you describe the primary audience of your product?

PermitCore.dev's answer:

PermitCore is primarily for indie developers, SaaS founders, small software teams, agencies, and established software vendors that want one complete path from creating licenses to implementing licensing and selling the finished product. Teams can create and manage licenses, integrate them through the REST API or SDKs, and then sell licenses directly through the built-in PermitCore Store without paying PermitCore a commission on those sales. It supports desktop applications, APIs, developer tools, plugins, and other paid software, with online, offline, floating, subscription, metered, and perpetual licensing. The permanent free plan helps developers get started, while larger teams can grow into reseller management, self-hosting, and custom roles.

What's the story behind your product?

PermitCore.dev's answer:

PermitCore started from a problem we kept running into while building our own software. Adding licensing looked simple at first, but it quickly became another product to maintain: secure key storage, validation APIs, device limits, offline use, subscriptions, customer access, payments, and support all needed their own infrastructure. We built PermitCore so developers could handle that complete journey in one place: create and manage licenses, implement them through an API or SDK, and sell them directly through a built-in Store with no commission taken by PermitCore. What began as an internal solution became a developer platform designed to let other teams focus on the software they actually want to build.

Which are the primary technologies used for building your product?

PermitCore.dev's answer:

PermitCore is built on .NET 10. The backend uses ASP.NET Core, Entity Framework Core, and PostgreSQL, while the administration panel and public website use Blazor WebAssembly. Valkey handles caching and distributed coordination, and the platform is deployed with Docker and Nginx. Stripe powers subscription and Store payment automation. For licensing security, PermitCore uses established cryptographic primitives including AES-256-GCM for browser-side encryption, HMAC-SHA256 for validation, and Argon2/PBKDF2 where appropriate for key derivation and credential protection. Client SDKs are available for .NET, Node.js, Python, Java, C++, and PHP.

Who are some of the biggest customers of your product?

PermitCore.dev's answer:

PermitCore is an early-stage startup, and we do not publish customer names without their explicit permission. Our current users include indie developers, SaaS founders, agencies, and software vendors using PermitCore to create licenses, integrate licensing into their products, and sell licenses through their own built-in Store.
