React + Phaser front • Spring WebFlux backend
Clean Architecture under the hood - born from my frustration with endless CRUD apps.
Anyone joins with a single link — every device has a browser.
WebSocket RTT < 50 ms even on budget servers.
Laptops, phones, Chromebooks — nothing to download.
Deterministic tick, combat and collision — cheat-proof.
Drag tiles, NPCs and triggers, autosave to DB.
Domain layer + ports & adapters on Spring WebFlux. Easy to unit-test and refactor.
Modern UI panels plus pixel-perfect canvas.
Local Mongo container or your own Mongo Atlas URI.
Terrain types, obstacles, two AI mobs and combat logic.
Swap forms and tables for path-finding and combat.
Launch a challenging side project fast.
Prototype a browser MMO in one week.

Java 21 + Spring WebFlux and React/TypeScript at mid-level. ChatGPT is your friend when stuck.
Yes. The data layer is decoupled — point it at any Mongo instance or replace with Postgres, Neo4j, etc.
Run `docker compose up` (local Mongo) or set `MONGO_URI` to Atlas and start coding.
Frontend fits Vercel/Netlify; backend runs on Heroku, Fly.io, AWS — just set your cloud Mongo URI.
Absolutely. Commercial use is included, no royalties.
