The Best Kajabi Alternative for WordPress: Sell Courses Without Monthly Fees
Kajabi is polished and all-in-one – but the monthly bill adds up fast and your course lives on someone else's platform. Here is an honest look at a WordPress-based Kajabi alternative that costs nothing to start.
If you are typing "kajabi alternative wordpress" into a search bar, you are probably somewhere between two feelings: you like what Kajabi promises, and you are not sure you want to pay for it forever. That tension is worth taking seriously. This article lays out what Kajabi genuinely does well, what it actually costs once you add it all up, and why building your course platform on WordPress – with a free, self-hosted plugin like MemberJet – might be the better fit for your business.
One thing upfront: this article comes from hafenstudios, the maker of MemberJet. We have an obvious interest in you finding MemberJet appealing. That is exactly why we are not going to trash Kajabi here. It is a good product used by thousands of course creators for good reasons. The question is not whether Kajabi is "bad" – it is whether its model fits how you want to run your business.
What Kajabi does well
Kajabi earned its reputation honestly. It is an all-in-one platform: course hosting, email marketing, sales funnels, checkout, and a website builder, all bundled together and hosted for you. You do not manage a server, you do not install updates, and you do not stitch together five different tools with Zapier. For someone who wants to launch a course this weekend and never think about infrastructure again, that convenience is real value.
The onboarding is smooth, the templates look professional out of the box, and the platform is built specifically for course creators and coaches – not adapted from a general-purpose CMS. If your priority is zero technical maintenance and a single login that does everything, Kajabi is a legitimately strong choice, and nothing below changes that.
The real cost of Kajabi
The convenience comes at a price, and it is worth looking at the full picture rather than just the sticker price.
The monthly fee never stops
Kajabi's plans run from roughly $149 to $399 per month depending on the tier, billed whether you sell one course or a hundred. That is $1,800 to nearly $4,800 a year, every year, for as long as your course business exists. It is not a one-time investment – it is rent. Miss a payment and your course site, your funnel, and your customer list all go dark at once, because everything lives inside the same platform.
Platform lock-in
Because Kajabi bundles hosting, funnels, email, and course delivery into one closed system, moving away later is genuinely painful. Your content, your design, your automations, and your customer data are all shaped around Kajabi's specific structure. Exporting and rebuilding elsewhere is a real project, not a button click. The more successful you become on Kajabi, the more expensive it gets to leave.
Transaction dependence
Some Kajabi plans and payment setups tie your checkout flow to their infrastructure and fee structure. Depending on your plan and region, that can mean your payment processing, your currency options, and your available integrations are constrained by what Kajabi decided to support – not by what your market actually needs. If you sell through a regional processor like Digistore24, for example, you are working around the platform rather than with it.
The WordPress ownership argument
WordPress flips the model. Instead of renting a course platform, you own the software that runs it. That distinction matters more than it might sound.
You own your data. Your courses, your member list, your progress records – all of it sits in a database you control, on hosting you choose. Nobody can lock you out, change the pricing on you, or shut down the platform you built your business on.
No mandatory monthly platform fee. WordPress itself is free. The plugin that turns it into a membership and course platform can be free too. You still pay for hosting, which you would need anyway, but you are not paying a per-month toll just to keep your course accessible.
GDPR control. If you sell into the EU, where your customer data physically lives and how it is processed is not a minor detail. Self-hosting on your own server, in your own choice of data center, gives you direct control over that question instead of trusting a third-party platform's compliance posture.
The trade-off is that you take on a bit more responsibility: you choose your host, you keep WordPress updated, and you are the one who sets things up. For many course creators, especially those already comfortable with WordPress or willing to learn, that trade is well worth it.
MemberJet as the alternative
MemberJet is our take on what a modern, self-hosted course and membership plugin should look like. It is free and released under the GPLv2 license, so there is no license fee standing between you and launching your course.
Courses with modules and lessons
MemberJet structures content the way course platforms are expected to: courses broken into modules, modules broken into lessons, with drip scheduling, progress tracking, and quizzes built in. It covers the same course-delivery basics you would expect from Kajabi's course area, running on your own WordPress install.
Native Digistore24 payment integration
If you sell through Digistore24 – common across German-speaking markets for its reseller model, VAT handling, and affiliate marketplace – MemberJet connects to it directly through its IPN interface, with SHA-512 signature verification and idempotent processing. A purchase unlocks access automatically. A refund locks it back down, reliably, without you touching anything manually.
AI features, bring your own key
MemberJet includes AI-assisted course tools built on Claude, using a bring-your-own-key (BYOK) model. You connect your own Anthropic API key and pay only for what you actually use, directly to Anthropic. That covers course and lesson drafting, quiz generation, and a RAG-based tutor that answers member questions grounded in your own course content – not a generic answer pulled from the open internet.
Security by design
Security is not bolted on afterward. Secrets are encrypted with libsodium, REST endpoints use real permission callbacks rather than superficial checks, and protected content is fail-closed by default – locked unless explicitly granted, never open by accident.
Your data stays in your database
Every course, lesson, and membership record lives in your own WordPress database. There is no external SaaS dependency for the core plugin to function. MemberJet is made in Hamburg by hafenstudios, and a paid Pro tier with additional features is coming soon – the current version is fully usable for free today.
Honest comparison: Kajabi vs. WordPress + MemberJet
| Kajabi | WordPress + MemberJet | |
|---|---|---|
| Monthly cost | $149–$399/month | $0 for the plugin, just hosting |
| Maintenance | ✓ Fully managed | You manage updates and hosting |
| Built-in email & funnels | ✓ Included | Not included, use a separate tool |
| Data ownership | Lives on Kajabi's platform | ✓ Your own database |
| GDPR / data location control | Depends on Kajabi's infrastructure | ✓ You choose your host |
| Digistore24 integration | Not native | ✓ Native IPN with SHA-512 |
| AI course tools | Limited / platform-dependent | ✓ Claude, bring your own key |
| Platform lock-in | High, hard to migrate away | ✓ Low, standard WordPress export |
| Setup effort | ✓ Minimal | Some initial WordPress setup |
Who should honestly stay on Kajabi
Kajabi is the better choice if you want the absolute least amount of technical involvement and are happy to pay monthly for that. If built-in email marketing, sales funnels, and course hosting under one login matter more to you than owning the underlying platform, switching would likely cost you more in setup time than it saves in fees. If you are not comfortable managing a WordPress site, or you do not want to think about hosting at all, Kajabi's managed model removes that burden entirely, and that is worth real money.
It is also worth staying on Kajabi if you are already deep into its funnel and email automation and rebuilding that logic elsewhere would take longer than the switching costs justify right now.
Migration outline: moving from Kajabi to WordPress
If the ownership argument resonates with you, a realistic migration looks roughly like this:
- Set up WordPress on a host of your choice and install MemberJet
- Export your course content from Kajabi (video links, text, downloads) and rebuild the module and lesson structure in MemberJet
- Connect your payment processor – for Digistore24 sellers, MemberJet's native integration handles this directly
- Export your member list from Kajabi and import it, then communicate the switch clearly so nobody loses access mid-transition
- Run both platforms in parallel briefly for new signups before fully retiring the Kajabi subscription
It is real work, not a one-click import, but it is a bounded project rather than an ongoing cost. Once it is done, it is done – you are not paying a monthly fee to keep the result.
Honest conclusion
Kajabi is the better choice when you want a fully managed, all-in-one platform with built-in email and funnels, you are comfortable with the monthly fee as the price of convenience, and you would rather not touch WordPress at all.
WordPress with MemberJet is the better choice when you want to own your data and avoid a recurring platform fee, you sell through Digistore24 and want a native integration, you care about controlling where your data lives for GDPR reasons, and you are willing to take on a modest amount of setup and maintenance in exchange for that control.
Neither path is wrong. The right one depends on how much you value convenience versus ownership, and on how your business actually sells. If you have read this far, you likely already know which side of that trade-off you are on.

Frequently asked questions
Is MemberJet really free?
Yes, MemberJet is really free – the core plugin is released under the GPLv2 license with no license fee and no required monthly platform charge, unlike Kajabi's $149–$399 per month. It includes course structure, drip scheduling, quizzes, and native Digistore24 payment integration at no cost. A paid Pro tier with additional features is coming soon, but the current version is fully usable for free today. You still pay for your own WordPress hosting, just not a per-month toll to keep your course accessible.
Can I migrate from Kajabi to WordPress?
Yes, you can migrate from Kajabi to WordPress, though it's manual work rather than a one-click import. You set up WordPress with MemberJet, export your course content and member list from Kajabi, and rebuild the module and lesson structure in MemberJet. For Digistore24 sellers, MemberJet's native IPN integration handles reconnecting the payment processor directly. It's realistic to run both platforms in parallel briefly for new signups before retiring the Kajabi subscription – a bounded project, not an ongoing cost.
Does MemberJet include email marketing like Kajabi?
No, MemberJet does not include email marketing or sales funnels the way Kajabi does. MemberJet focuses specifically on membership and course delivery – access control, modules and lessons with drip scheduling, quizzes, and native Digistore24 payment integration. For email marketing and funnels, you would pair it with a separate tool, since Kajabi bundles hosting, funnels, email, and course delivery into one closed system and MemberJet deliberately doesn't. That trade-off comes with the ownership model: more flexibility, less bundled convenience.
How does the AI course generation work?
MemberJet's AI course generation works on a bring-your-own-key (BYOK) model built on Claude. You connect your own Anthropic API key and pay only for your actual usage directly to Anthropic, rather than paying MemberJet a markup. It covers course and lesson drafting and quiz generation, plus a RAG-based tutor that answers member questions grounded in your own course content rather than a generic internet answer. No data is routed through a third-party SaaS layer beyond that direct API call.
Do I need to be technical to use MemberJet?
You don't need to be highly technical to use MemberJet, but basic WordPress familiarity helps – it's built for course creators, not developers. You will need to choose a WordPress host and keep the site updated, which is more hands-on than a fully managed platform like Kajabi. In exchange, you get full ownership of your data and no recurring platform fee standing between you and your course. For most course creators already comfortable clicking around a WordPress dashboard, that trade is well within reach.
