# Welcome to Medusa The Medusa stack exists out of: * 🐲 Hydra - Gateway / Service discovery / Security * 🦑 Medusa - Serverside rendering framework * 💮 Narcissus - Regression testing for stack The goal is to create an easy-to-use, enterprise-ready micro-frontend UI framework in HTML/CSS and Java. In Medusa, pages are simply written in HTML and enhanced with Medusa expressions to allow for efficient DOM rewrites. Following the model set forth from Elixir/Phoenix Liveview, all interactivity is handled serverside through WebSockets. The event-driven serverside code is written around non-blocking Spring Reactive. You have to write no Javascript but get full interactivity. Combine Medusa with Hydra for modularity. The goal of Hydra is to be an entry point gateway proxy that allows you to deploy frontends modularly. It is a ready-for-use combination of a gateway with service discovery, load balancing, and JWT security. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
