Community Building Platform: Skool vs Circle vs Kajabi
Judge a community building platform on engagement, data ownership, payments and ad tracking, plus a short Circle vs Kajabi 2026 answer. Checked Oct 2026.
The short answer
In 2026 Circle starts at $89 a month billed annually, takes a 2% fee and connects your own Stripe account. Kajabi starts at $143, takes no revenue share, charges 2.9% plus $0.30 on US cards and supports the Meta Conversions API. Choose Circle if members pay to be together, and Kajabi if they pay for a program.
AdvLaunch is the AI agency for coaches and consultants. In our paid community program, we run paid Meta acquisition into paid communities on Skool, Circle, Kajabi, Mighty Networks and other platforms, so we see which platform mechanics hold members after the ad click. We sell ad management, not software, so weigh our view with that stake in mind.
What Makes a Community Building Platform Good
A good community building platform gives members a reason to return, lets you keep the audience and the data, and lets you see which ad produced which paying member. That gives four tests, and a platform has to pass the ones your business depends on:
- Engagement: the mechanics that bring a member back on a schedule, such as events, streaks, levels and notifications.
- Retention: whether progress, status or an unfinished program gives a member a reason to stay another month.
- Ownership: who holds the payment relationship, and whether you can export members and their email addresses.
- Payments and tracking: what the platform charges per sale, and whether purchases reach your Meta ad account.
This page judges platforms on those tests using each vendor's own documentation, read on 8 October 2026. It is not a price list or a weighted scorecard: our community platform comparison covers prices side by side, and our best online community platform ranking covers the scorecard.
Engagement and Retention Mechanics to Look For
Engagement mechanics are the built-in loops that pull a member back, and the useful question is which loop matches how your members actually return. Skool's levels run from 1 to 9 on a points curve, where one like on a post is one point, and an admin can lock a course until a member reaches a level. Kajabi awards points for actions such as completing challenges, commenting and reacting, and ties badges to finishing courses, lessons and quizzes and attending events, with titles and a leaderboard on top.
Mighty Networks lists points, leaderboards, member streaks and a referral program on every plan, with advanced leaderboards on Growth and above. Circle's pricing page lists gamification, live events, courses and iOS, Android and desktop apps on its entry plan. Thinkific includes a community with a private feed, direct messages and weekly digests from its Basic plan.
Members return daily for status, streaks and progress
Skool or Mighty Networks
Skool's like-based levels can gate courses. Mighty lists streaks, points and leaderboards on every plan, and 20 to 50 streaming hours a month depending on plan.
Members return for live events, chat and cohorts
Circle or Mighty Networks
Circle bundles live events, chat spaces and native apps on every plan. Mighty lists private groups, cohorts and simultaneous livestreaming events.
Members return to finish a program
Kajabi or Thinkific
Kajabi ties badges to lessons, quizzes and events inside the same account as the course. Thinkific puts a community beside courses from its Basic plan.
None of these vendors publishes retention data that applies to your offer, so treat every mechanic as a hypothesis to test. A leaderboard cannot rescue a cohort that joined without understanding what it bought. Measure retention for each campaign cohort separately, and compare cohorts before you credit or blame the platform.
Who Owns the Audience, the Data and the Payment
Ownership comes down to two questions: who holds the payment relationship, and what can you export if you leave. The platforms differ more here than in features, and the answers decide how portable your community is.
| Decision factor | Who holds the payment relationship | What you can take with you |
|---|---|---|
| Skool | Skool is the merchant of record and pays you weekly through a Stripe Express account it creates. Skool's help center says you cannot use your existing Stripe account | Membership questions (up to three, one of them an email field) can be exported. On Pro, Zapier can send each new paid member's name and email to your CRM. Hobby has no Zapier |
| Circle | Paywalls are powered by Stripe, and Circle says you can connect your existing Stripe account | Bulk import and export is listed on every plan. Circle's help article lists member name, email, tags and profile fields, plus posts and comments, without uploaded media |
| Kajabi | Kajabi Payments, or a third-party processor with a 2%, 1% or 0.5% Kajabi surcharge. Kajabi takes no revenue share | A contacts CSV from the Contacts tab, emailed to you with a link that expires in 3 days, limited to your plan's contact cap |
| Mighty Networks | You connect your own Stripe account and Mighty does not store card details | An Excel member list with emails, tags and active-plan intervals, from the Launch plan up. Mighty's docs say you own your content and member data |
Sources: Skool, Circle, Kajabi and Mighty Networks help centers and docs, read 2026-10-08. Circle's export article was last updated in 2022 and says admins request the full export by emailing support@circle.so, so confirm the current process with Circle before you rely on it.
The practical rule is to collect an email address at the first step of every funnel, in a tool you control, so the relationship does not exist only inside a login. Skool's platform policy also prohibits scraping data and automation requests, so use the export and Zapier routes it provides rather than scripts.
Payments and Ad Tracking: What to Check Before You Run Meta Ads
Before you spend on Meta ads, check whether the platform can report the join and the purchase back to your ad account, and on which plan. The vendors' own documents say:
- Skool has a Meta pixel plugin that tracks page views, membership requests and purchases. Skool warns against reusing one pixel across domains or connecting it to external CRMs, and its growth reports use last-touch attribution with a 90-day window (14 days for Skool Network and affiliates). Link-in-bio tools and redirects show as direct traffic.
- Kajabi supports the Meta Pixel and the Conversions API, sending lead and purchase events from its servers, and warns that running a third-party gateway such as Stape alongside Kajabi's access token can double-count purchases.
- Circle accepts a pixel through its Code snippets feature, which Circle says works in the browser only and does not affect its mobile apps, and gives each paywall a tracking-code field for custom JavaScript on the thank-you page. We found no Circle help article describing a native Conversions API connection.
- Mighty Networks' pricing page lists marketing pixel tracking from the Scale plan ($179 a month billed annually), while its help article says a Meta Pixel can be added from Launch, so confirm in your plan settings.
Verify with Meta's own Test Events tool before you scale spend, because a platform feature that exists on paper can still misfire on your checkout.
Five Community Building Platforms in Brief
These five cover the main routes creators take to a paid community, and each entry gives the engagement fact and the payment fact that matter most, from the vendor's own pages.
Skool
Skool combines a community feed, a classroom and a calendar under two plans, Hobby and Pro. Its engagement system is points and levels, and Pro charges 2.9% plus $0.30 per transaction up to $899 and 3.9% plus $0.30 above that, while Hobby charges 10% plus $0.30. Skool's Growth Boost is on by default and takes 30% of any customer Skool brings you, and Skool advises switching it off if you sell through a call or a funnel.
Circle
Circle's Professional plan is $89 a month billed annually with unlimited members, community, courses, live events, payments, gamification and native apps. It allows 20 spaces, 3 admins and 10 moderators at a 2% transaction fee, and Business ($199) drops the fee to 1% and adds workflows, APIs and an MCP server.
Kajabi
Kajabi's community sits inside a course and marketing platform, with one community on Basic and Growth and three on Pro. A branded mobile app that includes the community is a $199 a month add-on on Basic and Growth, and Kajabi's pricing page lists it as included in Pro. Card processing runs 2.7% to 2.9% plus $0.30 on Kajabi Payments.
Mighty Networks
Mighty Networks puts courses, events, chat and community in one network. Launch is $79 a month billed annually ($95 monthly) with a 2% transaction fee, 3 hosts and 10 moderators, and Scale at $179 adds the Admin API and Zapier.
Thinkific
Thinkific is a course platform with a community product inside it. Basic is $40 a month billed annually with one community and five spaces, Start is $82 with ten spaces, and Grow is $164 with three communities and twenty spaces.

Our Take: Choose the Platform After the Offer
Choose the platform after you know what members pay for, because the offer decides which of the four tests matters most. If members pay for each other, favour engagement loops and ownership: Circle, Skool or Mighty Networks. If they pay for a program, favour tracking and checkout: Kajabi or Thinkific. Every platform on this page is a competent host, and each has a real strength we can source.
AdvLaunch is the right call when your problem is members, growth or revenue and your offer already sells. It is probably not the right call yet if your community revenue is under about $20K a year, because the Scale Program would be premature. Ad spend is separate and paid from your own Meta Business Manager, and the budget is set with you on a call. The 45-minute call reviews your community, your current acquisition and whether the Flywheel fits, and we decline projects with no fit signal. In those cases a better platform choice and an organic launch are a more honest next step.
How AdvLaunch Fills a Community on Any Platform: The Community Flywheel™
Platform mechanics keep members after they join, but they do not bring strangers in. We call our acquisition system The Community Flywheel™, and it is the same on Skool, Circle, Kajabi or Mighty Networks:
- Hook: a Meta ad points to a paid challenge, webinar or masterclass we control, not to the community signup page.
- Result delivered: over seven days or one live event, your method produces a real outcome before anyone pays.
- Community upsell: graduates are offered the paid community at a founder rate, with checkout in your own platform account.
- Retention compounds: members arrive already bought in, and retention and lifetime value are measured against the campaign cohort, not assumed from a generic benchmark.
| Decision factor | What a community platform gives you | What AdvLaunch builds on top |
|---|---|---|
| Traffic | None. The platform hosts members and does not bring buyers, apart from options like Skool's Growth Boost | Meta ads to a paid challenge or webinar: 8 creative variants in the Launch Pack and 12+ new variants a month on the Scale Program |
| First page a stranger sees | A join page or paywall, written for people who already want in | A custom landing page built for cold paid traffic, with CRO optimization |
| Email and nurture | Notifications and digests, plus whatever email tool you connect | A 7-email nurture sequence that carries people from the event to the offer |
| Checkout and community | Your platform's paywall, spaces and members | Kept as is. Your community, checkout and members stay in your own account |
| Measurement | A pixel plugin or snippet, depending on platform and plan | Meta Pixel setup plus an attribution dashboard |
| Cost | Plans from $79 to $419 a month billed annually across Mighty Networks, Circle and Kajabi | We share the price on the call, once we know it’s a fit. Ad spend is separate and paid from your own Meta account. |
