Alaya’s software architecture is built on a JS technical stack.

The back-end is developed with NodeJS, exposing a secured Rest API. The data is stored and aggregated on MongoDB. It also relies on external services for sending emails and store users contents. It also hosts webhooks for server-to-server communications (payment confirmations, email sending errors, etc.)
