Xtreme Courses is a complete learning management system (LMS) plugin for WordPress. Build structured online courses in a React drag-and-drop builder, sell them through WooCommerce, schedule drip content, run auto-graded quizzes, issue verifiable PDF certificates, and keep students engaged with XP, badges, and leaderboards — all from your own WordPress site.
No upsells. No locked features. There is no “Pro” version of Xtreme Courses — every feature listed on this page ships in the free download and is fully functional out of the box. No upgrade nags, no feature gates, no artificial limits on courses, students, or enrollments.

Why Xtreme Courses?
If you’ve evaluated the established LMS plugins (LearnDash, LifterLMS, Tutor LMS, LearnPress, Sensei) you already know the pattern: the features you actually need to run a paid course business — certificates, drip scheduling, quizzes, e-commerce checkout, reporting — are spread across paid tiers and per-feature add-ons. Xtreme Courses is built differently:
The whole stack is free. Course builder, WooCommerce selling, drip content, quiz engine, PDF certificates, gamification, live lessons, reviews, analytics — nothing is held back for a paid tier.
Commerce-ready from day one. Native WooCommerce integration: one-time purchases, free enrollments, subscription-gated content, bundles, bulk enrollment coupons, and gift enrollment.
Modern WordPress stack. PHP 8.2+ with strict types, a React drag-and-drop course builder, custom REST API, Action Scheduler background jobs, and full uninstall cleanup.
Self-hosted and private by default. No telemetry, no external service calls unless you explicitly configure live Zoom lessons (disclosed below). Your course content and student data stay on your server.
WordPress.org-compliant. Fully GPL, no obfuscated code, every external-service touchpoint disclosed on this page.
A free alternative to LearnDash, LifterLMS, Tutor LMS, LearnPress, and Sensei for course creators who want the complete LMS feature set without per-feature pricing.
Core Features (Free):
React Drag-and-Drop Course Builder — Build structured courses with sections, lessons (video, text, PDF, audio), and quizzes using a visual drag-and-drop interface.
WooCommerce Integration — Sell courses as one-time purchases, free enrollments, or subscription-gated content. Supports bulk enrollment coupons and gift enrollment.
Drip Content Scheduling — Release lessons on a fixed date, X days after enrollment, or after completing the previous lesson. Visual Gantt-style drip timeline.

PDF Certificate Generator — Auto-generate personalized certificates on course completion with a public verification URL.
Student Dashboard — Tabbed dashboard showing enrolled courses, progress rings, certificates, achievements, and order history.

Live Lessons — Zoom SDK embed and Google Meet pre-join cards with calendar reminder emails (.ics attachment).
Analytics Dashboard — Chart.js-powered admin panel with enrollment trends, lesson funnel, quiz performance, revenue, active students, and certificate issuance rate.

Bundled libraries
This plugin bundles Chart.js v4.5.1 (MIT, Copyright 2014-2025 Chart.js Contributors) for the Analytics admin panel. The script is served from the plugin folder at assets/js/vendor/chart.umd.min.js — no third-party CDN is contacted.
External services
This plugin can connect to one third-party service. It is opt-in — it is only contacted when an admin or instructor explicitly creates a live lesson and a student attends it. The default install of the plugin does not contact any external service.
Zoom Meeting SDK (optional, used for live lessons)
If an admin or instructor creates a live lesson and pastes a Zoom meeting URL into the lesson, then when a student opens that lesson the plugin will:
Render an embedded Zoom client by enqueueing the Zoom Meeting SDK JavaScript directly from https://source.zoom.us/zoom-meeting-3.1.2.min.js on that lesson page only.
The Zoom SDK then connects to Zoom’s own infrastructure to join the meeting. The plugin itself does not send any data to Zoom from your server — all communication happens between the student’s browser and Zoom.
If you do not use the live-lesson feature (no live lesson with a Zoom URL is ever created), the Zoom SDK is never loaded and Zoom is never contacted.
