What each one is

The product in its own terms, so the numbers below have context.

AdonisJS

AdonisJS is a web framework for Node.js built entirely in TypeScript that bundles authentication, database management, form validation, email sending, background jobs, and caching into a single system. It takes an opinionated approach to web development, providing one recommended solution for common problems to help developers focus on building features rather than assembling and integrating separate packages.
