Who it’s for

Built for plugin authors & product teams.

The Ngabantu License Manager Backend is designed for Flutter plugin authors, app studios, and enterprises who need serious licensing without building a backend from scratch.

Flutter plugin authors

Sell premium plugins with secure license checks, automatic fulfillment, and analytics on revenue and usage.

Mobile SDK & app teams

Gate enterprise features behind license keys, validate activations, and track licenses across devices.

Enterprises & agencies

Standardize licensing across multiple products with a single backend, auditable payments, and dashboards.

Capabilities

End-to-end licensing pipeline out of the box.

The backend handles the full journey: payment, FX validation, secure license generation, email delivery, and ongoing analytics through the admin dashboard.

Licensing pipeline
  • Dual payment support with Paystack & PayPal.
  • Backend-side price and currency validation to prevent underpayment.
  • AES-256-GCM encrypted license keys with PBKDF2 and HMAC signatures.
  • Support for tiered plans (Single, Multi, Enterprise) including product/app limit enforcement.
  • Automatic email delivery of license keys via SMTP with your brand.
Security posture
  • Rate limiting for auth, payment, and webhook endpoints.
  • Hardened security headers and CORS configuration.
  • Timing-safe comparisons for sensitive checks.
  • Structured request logging with request IDs for debugging.
Admin experience
  • Overview KPIs for revenue, licenses, customers, and success rates.
  • Transactions, licenses, customers, and logs tabs in a single SPA dashboard.
  • CSV export support and resend-license workflows.
  • Webhook and error logs for Paystack/PayPal troubleshooting.
Architecture

A clean, auditable Node.js/Express service layer.

Under the hood, the backend uses a service-based architecture and can run with SQLite for quick setups or MySQL/PostgreSQL/MSSQL for production environments.

  • Dedicated services for admin, payments, webhooks, and license generation.
  • CLI tools for manual/offline license creation when needed.
  • Deployment scripts for generating a hardened, obfuscated production build.
  • Designed to sit next to your existing Ngabantu Workforce OS stack or run standalone.
