Best Online Course Platforms to Sell Your Knowledge (2026)

The online course market is projected to exceed $185 billion by 2026, and individual creators are capturing a growing share. Whether you teach photography, business strategy, coding, or yoga — there's never been a better time to package what you know into a digital product.

But choosing the wrong platform can cost you months. Some charge hefty transaction fees that eat into your revenue. Others look sleek but lack the marketing tools you need to actually sell. A few try to do everything and end up doing nothing well.

We built and launched a test course on each of these six platforms to evaluate them from a creator's perspective: course building experience, student experience, marketing capabilities, and — critically — what you actually keep after fees.

Quick Comparison

1. Kajabi — Best All-in-One Business Platform

Kajabi is the most expensive platform on this list, and it earns its price tag. Unlike every other option here, Kajabi doesn't just host courses — it replaces your entire tech stack. Email marketing, sales funnels, landing pages, community, podcasting, and course delivery are all built in. No integrations required.

For creators who are serious about building a knowledge business (not just publishing a single course), Kajabi eliminates the headache of stitching together Teachable + Mailchimp + ClickFunnels + Circle. That consolidation saves both money and mental overhead once you factor in what those separate tools would cost individually.

The course builder itself is polished. Video hosting is included (no YouTube or Vimeo needed), and you can create drip content, quizzes, assignments, and communities around each course. The student experience is excellent — clean, mobile-responsive, and fast.

Kajabi's pipeline builder is where the magic happens for revenue. You can create automated sales funnels with landing pages, email sequences, checkout pages, and upsells — all without leaving the platform. In our test, building a complete launch funnel took about two hours in Kajabi versus six hours cobbling together the same thing with separate tools.

2. Teachable — Best for First-Time Course Creators

Teachable strikes the ideal balance between simplicity and capability. If you've never built an online course before, Teachable's guided setup walks you through the process step by step: upload content, set pricing, customize your school, and publish. We had a test course live and ready to sell in under 90 minutes.

The course builder uses a simple curriculum structure: sections contain lessons, and lessons can include video, text, PDF downloads, quizzes, or code challenges. No drag-and-drop builder complexity — just straightforward content organization.

Teachable's standout feature is its native payment processing (Teachable Payments), which handles sales tax compliance for you — a genuine pain point that other platforms leave you to figure out. For creators selling internationally, this alone is worth the price of admission.

The main drawback is the 5% transaction fee on the Basic plan ($59/month). Moving to the Pro plan ($159/month) eliminates that fee and adds advanced features like affiliate marketing, graded quizzes, and priority support. For courses priced above $200, upgrading to Pro pays for itself quickly.

3. Thinkific — Best for Customizable Course Sites

Thinkific gives you more control over the course experience than any other platform in this price range. The drag-and-drop course builder supports video, text, quizzes, surveys, downloads, multimedia, and Brillium exam integrations. You can create complex curricula with prerequisites, drip schedules, and conditional logic.

The site builder is equally flexible. You get a full website builder (not just a course page) with customizable themes, custom domains, and the ability to create standalone landing pages, blog posts, and membership areas. If brand appearance matters to you, Thinkific delivers more design control than Teachable.

Zero transaction fees on all paid plans keep your margins intact. The Basic plan at $49/month includes one community, coupons, and affiliate selling. The Start plan at $99/month adds assignments, memberships, and bundles — the features most growing creators need.

4. Podia — Best for Simple Multi-Product Stores

Podia is built for creators who sell more than just courses. If you want to offer courses, digital downloads, coaching sessions, and community memberships from a single storefront, Podia makes it dead simple. There's no learning curve — you can have a course and a digital download listed for sale within an hour.

At $39/month (Mover plan) with zero transaction fees, built-in email marketing, and unlimited products, Podia offers exceptional value for creators who need simplicity over advanced features. The Shaker plan ($89/month) adds affiliate marketing and third-party code embedding.

5. Systeme.io — Best Free Option for Budget Creators

Systeme.io is the only platform on this list with a genuinely useful free plan. You get up to 3 courses, unlimited students, a sales funnel builder, email marketing (up to 2,000 contacts), and your own blog — all at zero cost with zero transaction fees.

The tradeoff is polish. The course builder is functional but basic, the templates are limited, and the student experience doesn't match the polish of Kajabi or Teachable. But for creators validating an idea or testing a market before investing in premium tools, Systeme.io removes all financial barriers to getting started.

6. Skillshare — Best for Audience Discovery

Skillshare is fundamentally different from every other platform here. You don't set a price for your course — students pay Skillshare a subscription ($14/month), and you earn royalties based on minutes watched. This means you don't control your revenue per student, but you gain access to Skillshare's existing audience of millions.

For creators who already have an audience, Skillshare's revenue model is usually a downgrade. But for new creators who have no following and no email list, Skillshare provides discovery that self-hosted platforms simply can't match. Many successful course creators use Skillshare as a top-of-funnel channel: publish introductory content there, then drive students to their own platform for premium courses.

How We Tested

We created a five-module video course (Introduction to Freelancing) on each platform, set up pricing, configured a basic sales page, and ran a small paid traffic test to measure the checkout experience. We evaluated course builder flexibility, student UX on desktop and mobile, marketing tools, payment processing, and total cost of ownership for a creator earning $5,000/month in course sales.
