How to choose an online course platform (2026 guide)
How to choose an online course platform in 2026: weigh fees, course experience, and email to pick the right tool, not the loudest one.
If you want a short answer on how to choose an online course platform in 2026, here it is: pick on transaction fees and course experience first, not the monthly sticker price. For most beginners that means Systeme.io — it has a genuinely free plan, 0% transaction fees, and bundles email and funnels in. If you want one tool to run an entire business, Kajabi is the most powerful (and the most expensive). And if courses are the actual product and you want the cleanest building experience, Thinkific is the one to beat.
That’s the recommendation. The rest of this guide is the reasoning — the five decision factors that actually move the needle, a comparison table you can scan in ten seconds, and a framework for matching a platform to where you are right now. Because the honest truth is there’s no single “best” platform. There’s the right platform for your budget, your content, and your list size, and those change as you grow.
The five factors that actually decide it
Most “best course platform” lists rank on feature counts. That’s the wrong lens. After using these tools, here’s what genuinely changes your outcome.
1. Transaction fees (this is the sneaky one)
The monthly price is visible. The per-sale fee is the one that quietly eats your margin. A platform that charges 7.5% per sale costs you $75 on every $1,000 you make — that’s $900 a year on modest volume, far more than most monthly plans.
Here’s where the major course platforms land:
| Platform | Entry price (annual) | Transaction fee | Free plan | Best at |
|---|---|---|---|---|
| Systeme.io | $0 | 0% | Yes (real) | Value, funnels, email |
| Kajabi | ~$71/mo | 0% | No (14-day trial) | All-in-one power |
| Thinkific | ~$36/mo | 0% | No (30-day trial) | Course experience |
| Teachable | ~$29/mo | 7.5% on Starter, 0% on Builder+ | No (7-day trial) | Cheap, fast launch |
Note Teachable: the $29 Starter plan looks like the budget winner until you read the 7.5% fee. If you sell more than a trickle, upgrading to Builder (0% fee) almost always works out cheaper. Run your own numbers in the pricing calculator — drag it to your student count and you’ll see exactly where each plan crosses over.
2. The course experience itself
This is what your students actually touch: the player, drip scheduling, quizzes, completion tracking, and how a lesson page feels. Thinkific is the strongest here — a polished drag-and-drop builder, quizzes, surveys, assignments, and bundled community. Kajabi is close and adds a branded member mobile app. Systeme.io is the honest weak spot: its course player and templates are basic compared to a dedicated LMS. That’s the trade-off you accept for free and 0% fees.
If interactive video, SCORM, or a fully branded academy matters, you’re shopping above this tier — but most creators never need that, and paying for it early is a common mistake.
3. Email and funnels: built-in or bolted-on?
A course platform that can’t email your buyers isn’t really finished — you’ll pay for a separate tool. This is where the all-in-ones earn their keep. Systeme.io includes unlimited email sends, funnels, and even affiliate management on every plan, free included. Kajabi has strong native email automation and funnels (Pipelines). Thinkific and Teachable are weaker here — great course players, weak email — so you’ll likely add an email marketing tool on top, which changes the real cost.
4. Who it’s actually for
Be honest about your stage. Kajabi is built for established creators with budget and a list; its $89/mo monthly entry and per-tier contact caps punish beginners. Systeme.io is built for bootstrappers. Thinkific sits in between — serious about courses, but priced above the free options. Matching the tool to your stage beats buying the most powerful thing you can afford.
5. How pricing scales
Watch the pricing model, not just the entry number. Systeme.io and Kajabi scale by contact count, so a growing list raises your bill. Thinkific and Teachable are flatter. A $0 plan that jumps to $97/mo at 10,000 contacts is still a great deal — but know the curve before you commit a year.
A recommendation framework
Skip the agonizing. Match yourself to one of these:
- You’re starting and budget is tight → Systeme.io, free plan. One course, payments, email, 0% fees, no card. Upgrade only when you outgrow 2,000 contacts.
- You want courses + email + funnels in one serious tool → Kajabi. Expensive, but you replace three subscriptions and get a polished member experience.
- Courses are the product and fees matter → Thinkific. Best pure building experience, 0% platform fees, community bundled in.
- You want the lowest monthly cost and will sell a few courses → Teachable — but plan to move to Builder to kill the 7.5% Starter fee once sales pick up.
If you’re still torn, our advisor asks a few questions about your budget, content, and goals and points you to a specific pick rather than a vague “it depends.”
When to upgrade (or switch)
A few honest triggers. Move off a free or Starter plan when the transaction fee you’re paying exceeds the next plan’s monthly cost — that’s pure math, and the pricing calculator shows the exact crossover. Switch platforms entirely when your bottleneck changes: if email and funnels are holding back sales, an all-in-one like Kajabi or Systeme.io beats a course-only tool. If your course experience feels cheap to students and that’s hurting completion, that’s when Thinkific’s polish earns its price.
Don’t switch for the sake of it. Migrating courses, members, and payment integrations is real work. Choose a platform you can grow into for at least a year.
FAQ
What’s the most important factor when choosing a course platform? Transaction fees, then course experience. A low monthly price with a 5–10% per-sale fee usually costs more than a higher flat plan once you’re selling regularly. After fees, judge the actual student-facing experience — the player, drip, and quizzes — since that affects completion and refunds.
Is a free course platform good enough to start? Yes, for most people. Systeme.io’s free plan hosts a course, takes payments at 0% fees, and includes email and funnels. The course player is basic versus Thinkific, but for validating an idea and making your first sales, free and 0% fees beat paying for polish you don’t need yet.
Kajabi vs Thinkific vs Teachable — which should I pick? Kajabi if you want one powerful tool for courses, email, and funnels and have the budget. Thinkific if courses are the product and you want the best building experience at 0% fees. Teachable if you want the cheapest start — just budget to leave the 7.5%-fee Starter plan as soon as you’re selling.
Do all course platforms charge transaction fees? No. Systeme.io, Kajabi, and Thinkific charge 0% platform fees (you still pay Stripe/PayPal processing). Teachable’s Starter plan takes 7.5%, dropping to 0% on Builder and up. Always check the fee before the monthly price.
The bottom line
Choosing an online course platform comes down to a simple order of operations: fees first, course experience second, email and funnels third, and price last. Start free with Systeme.io if you’re unsure, reach for Thinkific when the course experience becomes the priority, and step up to Kajabi when you want a whole business in one place. Compare every option side by side on the course platforms hub, run your real numbers through the pricing calculator, or let the advisor match you to a pick in under a minute. Pick the one you’ll grow into — then go ship the course.
