Three plugins dominate every "best WordPress LMS" list, and they are constantly recommended interchangeably even though they were built to solve different problems. MemberPress is a membership and paywall plugin that grew course features. LearnDash is a serious course-authoring engine that bolts membership on through add-ons. LifterLMS was designed from day one to fuse the two. Picking the wrong one rarely produces an obviously broken site, just a slow-grinding mismatch: you fight the tool for features it was never the best at, and you pay for add-ons that paper over the gap.

The single question that sorts the three faster than any feature table: is your primary product recurring access to a library, or a structured course someone completes? Answer that honestly and two of the three usually fall away.

The fastest way to decide

Recurring-access membership site (content library, community, monthly tiers, drip): MemberPress.
Assessment-heavy training or certification (quizzes, grading, certificates, compliance): LearnDash.
A coaching/creator business that needs courses and memberships equally, with built-in checkout and order bumps: LifterLMS.

If you can't decide between two, the tie-breaker is your billing model, not your content. Whoever owns billing most cleanly should own the whole stack.

MemberPress: access control first, courses second

MemberPress thinks in rules: a piece of content (post, page, category, custom post type, file) is protected, and a membership grants access to it. That model is its strength. Drip schedules, expiring access, paywall content, and "first chapter free then upgrade" funnels are trivial because access control is the core abstraction, not an afterthought.

Its Courses add-on (included, not extra) gives you a clean Gutenberg-based curriculum builder with sections, lessons, and progress tracking. It is genuinely pleasant for a content library or a cohort-style program. What it is not is an assessment platform. Quizzes are basic, there is no real gradebook, and certificate logic is shallow. If a learner has to pass something, MemberPress is the wrong tool.

Where it shines is money and access. The billing engine handles subscriptions, one-time payments, upgrades/downgrades with proration, coupons, and dunning. Stripe and PayPal are first-class, and the corporate-accounts and group features let one buyer seat a team. For a site whose product is "pay monthly, keep getting in," nothing here is cleaner.

LearnDash: the course engine

LearnDash is built around the course → lessons → topics → quizzes hierarchy, and the quiz engine is the reason serious training teams choose it. You get multiple question types (single/multi choice, fill-in-the-blank, matching, sorting, essay/open answer with manual grading), question banks with randomization, time limits, pass/fail thresholds, retake limits, and certificates that fire on completion or on passing a specific quiz. The ProPanel add-on gives instructors a reporting dashboard, and Groups handles cohorts with group leaders who can see their members' progress — the backbone of corporate L&D and academic use.

The trade-off is that LearnDash is a teaching tool, not a business platform. It has no native checkout worth the name. To sell anything beyond a single product you pair it with WooCommerce (and the official LearnDash WooCommerce integration) or a membership layer. That is more moving parts, more plugins to update, and more places for a payment edge case to hide. If your offering is genuinely course-shaped — people enroll, work through structured material, and earn a credential — the assessment depth pays for that complexity. If you just want to gate a video library behind a subscription, you have over-bought.

LearnDash 4.x and the block builder

The modern LearnDash uses a block-based course builder and integrates with full-site-editing themes far better than its older self did. If your only memory of LearnDash is the clunky pre-4.0 admin, it is worth a fresh look — the authoring experience improved substantially.

LifterLMS: the integrated middle

LifterLMS is the one that tries to do both jobs in a single plugin, and it largely succeeds. It ships its own checkout, order bumps, coupons, and access plans, so you can sell a course, a membership, or a bundle without WooCommerce. Memberships, drip content, and a course builder all live under one roof, with engagement triggers (email a student when they finish a lesson, award a badge, issue a certificate) that feel cohesive rather than stitched together.

Its quizzes sit between MemberPress and LearnDash: real quizzes with question banks and passing grades, but not LearnDash's breadth of question types or grading workflow. The honest framing is that LifterLMS is the best single-plugin answer when you refuse to run a stack — strong for coaches, creators, and membership-plus-courses businesses, weaker than LearnDash for heavy certification and weaker than MemberPress for pure subscription-library billing.

What it actually costs

Prices below are list pricing as of early 2026; all three vendors have been raising prices roughly 10–15% a year, so confirm on the vendor site before you commit.

MemberPress — around $179–$199/year for a single site at the Basic tier; Courses is included, so a working course site can run on the base license.
LearnDash — around $199/year for one site. Plan for add-ons: ProPanel, Groups Plus, and the WooCommerce or Stripe Connector each add cost or complexity, so a real selling site lands closer to $300–$450/year once you can take money properly.
LifterLMS — free core, but the practical path is the add-on bundle at roughly $360/year, which folds in payment gateways, advanced quizzes, and integrations that you would otherwise buy à la carte.

The cheapest sticker price is misleading. Cost is driven by how many add-ons your real feature list forces you to buy, and LearnDash is the one most likely to surprise you because billing lives outside the plugin.

The decisions people regret later

Migration is brutal. Each plugin stores courses, lessons, and progress in its own custom post types and metadata. There is no clean one-click move between them. Switching after you have enrolled students typically means exporting, rebuilding the curriculum by hand in the new plugin, and re-enrolling people — sometimes losing completion and quiz history entirely. Choose as if you are choosing for years, because you effectively are.

Never self-host course video on shared hosting. This sinks more LMS sites than any plugin choice. Streaming MP4s from a $5/month shared plan produces buffering, bandwidth overages, and a tanked experience. Host video on Vimeo, Wistia, or Bunny Stream and let the LMS handle only structure and progress tracking. Pair that with managed WordPress hosting (Kinsta, WP Engine, Cloudways) and object caching; a logged-in LMS bypasses most page caching, so server response time (aim for a TTFB under ~600 ms) matters more here than on a brochure site.

What about Tutor LMS and the rest?

Tutor LMS is the credible fourth name. Its Pro tier (~$199/year) has closed most of the feature gap, ships a frontend course builder and a native marketplace mode for multi-instructor sites, and is actively developed. For a fresh 2026 build with a multiple-instructor model, it deserves a spot on the shortlist. It still trails LearnDash on certification depth and MemberPress on subscription billing. Sensei (from Automattic) is the natural pick only if you are already all-in on WooCommerce and want tight first-party integration.

One-line verdict

Sell access, and choose MemberPress. Sell mastery that someone has to prove, and choose LearnDash. Sell both from one checkout without assembling a plugin stack, and choose LifterLMS. The mistake is treating them as three flavors of the same thing — they are three different businesses wearing the same "WordPress LMS" label.
