Init User Engine – Gamified, Fast, Frontend-First

Add a modern, gamified user system to WordPress with EXP levels, Coin/Cash wallet, VIP, referral, and full JS modals – all powered by REST API.

Pure JavaScript. Real-time REST API. Built for frontend-first WordPress.

Overview

Init User Engine is a gamified user module built from scratch for frontend-first WordPress sites. Everything runs via REST API and Vanilla JS — no jQuery, no PHP-based forms, no bloat.

You get full control over user interactions: check-in, VIP purchase, Coin/EXP rewards, inbox notifications, referral tracking — all in one slick modal dashboard.
