Khan Academy

If you mean platforms for taking online courses, the top “real people actually use these” brands are:

My quick recommendations

• If you want a job-relevant certificate: start with Coursera.
• If you want the cheapest practical course: use Udemy, but check ratings, update date, and reviews carefully.
• If you want university-style content: use edX or Coursera.
• If your employer pays: use LinkedIn Learning, Coursera, Pluralsight, or Udemy Business.
• If you’re learning to code for free: use freeCodeCamp first, then add Codecademy, CS50, or The Odin Project depending on your goals.
• If you’re learning data/analytics: try DataCamp for practice, Coursera for certificates, and Kaggle for projects.
• If you’re learning math or school subjects: Khan Academy is the default pick.

If you meant platforms to create and sell online courses

The biggest practical shortlist is:

Bottom line: for learning, most people should compare Coursera, Udemy, edX, LinkedIn Learning, Khan Academy, and Pluralsight first. For selling courses, start by comparing Teachable, Thinkific, Kajabi, Podia, and Skool.

Online course platforms generally fall into two categories depending on what you're trying to do: taking courses to learn something, or building and selling your own courses. Here's a breakdown of the platforms people actually use most in each category.

For Learners (Taking Courses)

Coursera is consistently rated the top choice for learners wanting recognized credentials. Coursera is the best online learning platform in 2026 for most learners, partnering with over 300 universities and companies to offer courses with recognized credentials, including Google and IBM Professional Certificates. It also offers strong value for frequent learners — Coursera Plus subscription gives access to 90% of the catalogue at $399/year, and you can audit most courses for free, paying only when a certificate is needed.

Udemy is the go-to for cheap, targeted skill-building. Udemy offers 250,000+ courses at lower per-course prices ($12-20 on sale) with lifetime access but no formal credentials.

edX is best if you want prestigious, university-level credentials — including pathways like edX's MIT MicroMasters in Statistics and Data Science, which is accepted as the first semester of a full master's degree at some universities.

LinkedIn Learning is widely recommended for professional/career development — Choose LinkedIn Learning for soft skills and career development, Udemy for targeted technical skills, or edX for prestigious professional certificates.

Khan Academy remains the top free option, especially for younger learners: For free learning, Khan Academy covers K-12 and college-level content at no cost.

Skillshare rounds out the group for creative/hobby-style classes (design, illustration, video, etc.), and is often mentioned alongside these as one of the major instructor-led marketplaces.

Money-saving tip: If cost is an issue, Coursera has a lesser-known financial aid option — anyone, regardless of citizenship, can apply for Financial Aid on Coursera Professional Certificates; the application takes 15 minutes, requires a short essay, and approves an estimated 70%+ of applications, after which the certificate is genuinely free, identical to the paid version.

For Creators (Building & Selling Your Own Courses)

If you want to teach and sell your own course, the "big three" that dominate this space are:

• Teachable – Best for creators starting fast, for course building, payments, and digital products in one place.
• Thinkific – Best for education and training businesses, for branded course delivery without a full website stack.
• Kajabi – frequently benchmarked against as the premium all-in-one option combining course hosting, marketing, and sales funnels (several guides even market themselves as "Kajabi alternatives," underscoring how dominant it is in this space).

Other names that consistently show up in independent comparisons include Podia, LearnWorlds, LearnDash (a WordPress LMS plugin), Mighty Networks and Circle (community-first platforms), and Skool (community + course hybrid).

I'll research the most popular and highly regarded online course platforms based on current usage and reviews.I'm gathering more details on the most widely used platforms in both learning and course-creation categories.I have enough data to compile recommendations. Here are the top online course platforms based on popularity, user base, reviews, and real-world usage.The best online course platforms fall into two main categories: those people use to take courses (learning marketplaces and MOOCs) and those creators use to build and sell their own courses. “Best” depends on whether you’re a learner or a creator, your budget, topic, and goals (e.g., career credentials vs. creative skills vs. selling high-ticket courses). Below are the top brands people actually use, based on user bases, reviews, market presence, and expert roundups.

Top Platforms for Taking Courses (Most Popular Among Learners)

These have massive audiences and are what most people mean when they say they “took an online course.”

Coursera and Udemy dominate everyday usage. Coursera stands out for recognized credentials and structured learning paths that employers value. Udemy wins for breadth, low cost (especially during sales), and practical “how-to” content. Many people start on Udemy for specific skills and use Coursera/edX for more formal upskilling.

Top Platforms for Creating & Selling Your Own Courses

These are the go-to tools for independent creators, coaches, and businesses. Marketplaces (Udemy/Skillshare) give built-in traffic but take a large revenue cut and limit branding/control. Dedicated platforms give full ownership.

Most recommended / widely used:

• Teachable — Excellent all-around choice for beginners to intermediate creators. Easy course builder, marketing tools (coupons, affiliates), coaching/digital products support, and student apps. Creators have earned billions in total on the platform; 100M+ students served and 150k+ creators. Strong for building an “online school.” Plans start relatively accessibly (with transaction fees on lower tiers).
• Thinkific — User-friendly, highly customizable, strong course templates, and often no/low transaction fees on paid plans. Great student experience and add-ons. Frequently praised as a solid free/affordable starter or mid-tier option with good support. Popular for coaches and those wanting flexibility.
• Kajabi — Premium all-in-one suite (courses + email marketing + website + funnels + automations + community). Ideal if you want everything in one place and are selling higher-ticket offers. More expensive, but reduces the need for multiple tools. Often called the “ultimate” or most complete platform.
• LearnWorlds — Strong for interactive/engaging courses (interactive video, ebooks, assessments, social features, even mobile apps). Good customization and marketing. Frequently tops “best of” lists for features.
• Podia — Simple and clean for courses + digital downloads + memberships. Affordable and straightforward.
• Others worth noting: Mighty Networks or Circle (excellent if community is central); Kartra or Simplero (heavier marketing/automation focus); WordPress LMS plugins like LearnDash (for full ownership/control if you’re technical).

Marketplaces for creators (easier discovery, less marketing needed initially):

• Udemy — Best for launching your first course and tapping a huge existing audience (but high revenue share, typically 37–97% depending on promotions, and less branding control).
• Skillshare — Great for creative teachers (royalties based on watch time).

Quick Recommendations by Use Case

• Just want to learn something affordable/practical → Udemy (or free options on Coursera/Khan Academy).
• Career advancement or university-style credentials → Coursera or edX.
• Creative hobbies/projects → Skillshare.
• Creating your first course with built-in traffic → Start on Udemy or Skillshare.
• Building a branded course business / owning your audience → Teachable or Thinkific (easier/cheaper entry) or Kajabi (all-in-one power).
• Highly interactive or community-focused courses → LearnWorlds, Circle, or Mighty Networks.
• Budget-conscious creator → Thinkific free/basic tiers or Teachable starter; test ideas on marketplaces first.
• Enterprise/internal training → Dedicated LMS options or Coursera/Udemy for Business, LinkedIn Learning.

Key Factors When Choosing

• For learners: Content quality/reputation, certificates that matter, price, completion tools, and mobile experience.
• For creators: Ease of use, transaction fees vs. monthly cost, marketing/automation features, customization/branding, payment options, student engagement tools (quizzes, community, drip content), and support. Most offer free trials.
• Trends: AI course-building tools are increasingly common; community features boost completion rates; all-in-one platforms reduce tool-switching.

Popularity shifts with trends (e.g., AI/skills courses boom), but Coursera, Udemy, Teachable, Thinkific, and Kajabi consistently top “people actually use” lists across reviews and stats. Check current pricing and free trials directly, as they change, and read recent user reviews for your specific niche. If you share more details (learner vs. creator, topic, budget), I can refine this further.
