Init User Engine is a lightweight, no-bloat user system for modern WordPress sites. It replaces the default profile/login experience with a full gamification layer — EXP & levels, a Coin/Cash wallet, daily check-in, VIP membership, referrals, and an inbox — all rendered through a fast, modal-driven frontend powered by the REST API.
No jQuery. Minimal settings. Smart by default.
Why Init User Engine?
Most "membership" or "points" plugins for WordPress are heavy, admin-ajax-based, and hard to theme. Init User Engine takes the opposite approach: everything dynamic — avatar, dashboard, check-in, inbox, VIP purchase — is rendered client-side in pure Vanilla JS and talks to a clean REST API. Drop in one shortcode and you get a full gamified account system on top of native WordPress users.
It's the core user system behind the Init Plugin Suite — the same minimalist, performance-first philosophy as Init Live Search.
Features at a Glance
Gamified Progression
- EXP & Level system with fully hookable progression logic
- Coin & Cash wallet with transaction logs (dedicated DB tables, not user meta)
- Daily check-in with streak milestones and an online-time bonus timer
- Daily task list, extensible via filter
Frontend-First UX
- One shortcode:
[init_user_engine]— avatar button + full modal dashboard - Avatar system with upload, live preview, and revert-to-default support
- Login/Register modals for logged-out visitors, with custom redirect URLs
- Pure Vanilla JS — no jQuery, no server-rendered admin-ajax round trips
Monetization & Retention
- VIP membership, purchased with in-site Coin, with configurable duration tiers (including lifetime)
- VIP bonus system — extra Coin/EXP percentage for VIP members
- Redeem Code / Gift Code module — generate single-use or bulk codes, redeem for rewards
- Referral module with cookie-based signup tracking and rewards for both sides
Communication
- Built-in inbox with pagination, category filters (System, Rewards, Activity...), read/claim/delete
- Admin panel to send notifications to selected users or the whole member base, with priority and expiration
Built for Developers
- REST API for every feature — register, check-in, claim reward, inbox, VIP purchase, redeem code, profile, and more
- Deep set of action/filter hooks: modify EXP curves, VIP prices, referral rewards, theme colors, VIP body classes, and more
- Transaction and EXP logs stored in dedicated tables with
wp_cachesupport and true paginated queries — built to scale, not just to demo

Developer Hooks
Init User Engine ships with a wide surface of filters and actions so you're never stuck waiting on a plugin update to customize behavior:
// Change how much EXP is required per level
add_filter( 'init_plugin_suite_user_engine_exp_required', function( $required, $level ) {
return $level * 100;
}, 10, 2 );
// React to a level-up
add_action( 'init_plugin_suite_user_engine_level_up', function( $user_id, $new_level ) {
// send a custom notification, unlock content, etc.
}, 10, 2 );
Other notable hooks include filters for VIP pricing, referral rewards, check-in milestones, daily tasks, theme colors, and VIP-related body classes — plus actions for EXP/Coin changes, referral completion, and admin notifications.
Where Data Lives
-
user_meta— EXP, level, Coin, Cash, VIP, referral - Dedicated DB tables — transaction log and EXP log (migrated off user meta for scalability as of v1.5.0)
-
wp_init_user_engine_inbox— inbox messages
Installation
Install via WordPress.org or:
git clone https://github.com/brokensmile2103/init-user-engine.git
Then:
- Activate the plugin
- Drop
[init_user_engine]into any page, post, or template - Configure theme color, currency labels, and reward values under Settings → Init User Engine
That's it — modals and logic load automatically.
