The short answer
Both sides assessedCircle compared with Heartbeat
Heartbeat starts at $49 a month against Circle's $89, but caps you at 350 members and charges a 5 percent transaction fee at that tier, and its branded mobile app requires the $849 Scale plan. Circle has unlimited members and a 2 percent fee from the start. Heartbeat is the better buy for a small, chat-heavy community under a few hundred people; Circle is the better buy the moment membership revenue is real, because the fee difference alone dwarfs the subscription gap.
Heartbeat compared with Circle
Circle costs $89 with unlimited members and a 2 percent fee, against Heartbeat's $49 for 350 members and a 5 percent fee. Circle is forum-shaped with a deeper monetization and email stack; Heartbeat is chat-shaped with better automation workflows and a custom domain at half the price. Take Heartbeat for a small chat-heavy community where the real-time feel matters. Take Circle the moment membership numbers or revenue grow, because unlimited members and a lower fee will beat Heartbeat's banding quickly.
Choose Circle if
Creators, coaches, and small businesses running a paid membership or cohort program who want courses, events, discussion, and billing in one branded product on their own domain, and who are doing enough revenue that a 1 to 2 percent platform fee is a rounding error rather than a tax.
Choose Heartbeat if
Coaches, cohort operators, and creators running a chat-heavy paid community of a few hundred to a few thousand members who want Discord's conversational feel with a paywall, a course builder, automation, and their own domain, and who value real-time energy over threaded permanence.

| Setup time | A working community in an afternoon. Signing up, creating spaces, connecting a custom domain, and wiring Stripe are all self-serve and take a few hours combined. Getting the content and the onboarding sequence right is the part that takes weeks. | A live community in an afternoon. Channel structure, a course outline, a landing page, and Stripe connection are all self-serve, and the custom domain is included from the entry tier so you are not deferring that step. |
| Learning curve | Moderate for the admin, low for members. The spaces model, permission layers, and paywall rules interact in ways that reward reading the docs before you build, and communities that improvise their structure usually rebuild it once. Members need no instruction. | Low for anyone who has used Discord or Slack, which is most of the target market, and that familiarity is the main argument for the chat-first model. Automation workflows are the one area with a real learning curve, and they are also where most of the operational value sits. |

Strengths and limitations
Circle
Strengths
- The broadest feature set on a published price in this category: discussion, courses, events, live streaming, chat, payments, affiliates, a website builder, and native mobile apps all on the $89 tier.
- Unlimited members on every plan, so growth does not trigger a pricing cliff the way it does on Heartbeat or Bettermode.
- Custom domain and a white-labeled member experience from the entry tier, which is the thing free chat platforms fundamentally cannot offer.
- Native iOS and Android apps with push notifications keep engagement materially higher than a browser-only forum.
Limitations
- No free plan at all, which makes Circle a poor fit for a small free community and a hard sell for anyone testing whether a community is worth running.
- The transaction fee stacks on Stripe and is charged on gross, so a low-margin membership business pays Circle more than the subscription costs and cannot reach the 0.5 percent rate without a sales conversation.
- Branded mobile apps and custom SSO are both locked behind the unpriced Circle Plus tier, so the two things a maturing community most wants next are exactly the two things with no published cost.
- Admin and moderator seat caps of 3 and 10 on Professional are tight for a volunteer-moderated community and force an upgrade for reasons unrelated to features.
Heartbeat
Strengths
- The chat-first structure genuinely produces a different community feel from forum-shaped competitors, and voice and video rooms create spontaneous conversation that scheduled events cannot.
- A custom domain on the $49 entry tier, which almost nothing else in this category offers at that price.
- Unlimited channels, courses, events, and documents on every plan, so the entry tier is feature-complete rather than crippled.
- Native iOS and Android apps included from the entry tier, which is a meaningful engagement advantage over web-only platforms like Bettermode and Discourse.
Limitations
- Member-count pricing bands are the wrong shape for free communities, since 5,000 members costs $149 a month whether or not any of them pay you anything.
- The 5 percent Build transaction fee is the highest published rate among serious platforms here, and stacking it on Stripe means roughly 7.9 percent all-in on the entry plan.
- The branded mobile app requires the $849 Scale tier, which is a very expensive way to get your own icon on a phone.
- The step from Grow to Scale is a 5.7-fold price increase triggered by member count, with no intermediate tier to soften it.
Pricing compared
Circle
Flat monthly platform subscription with unlimited members, plus a percentage transaction fee on every paid membership, course, or event sold through Circle checkout, plus paid add-ons for email marketing.
- Professional$89
- Business$199
- Circle PlusCustom
For a community that is genuinely a business, Circle is fairly priced and hard to assemble from parts. Courses, events, live streaming, native mobile apps, a custom domain, recurring billing, affiliates, and search over unlimited history at $89 a month would cost more than that in separate tools, and the tools would not share a member identity. For a community that is not yet a business, Circle is expensive in a way the sticker hides: $89 plus 2 percent plus Stripe plus $99 of Email Hub is a real monthly commitment for a group that could sit on a free Discourse instance or a Discord server. The cutoff is roughly whether the community produces revenue. Above that line Circle is good value, below it the fee structure works against you.
Heartbeat
Flat monthly subscription banded by member count, with a separate percentage transaction fee on everything sold through Heartbeat's checkout that falls as you move up tiers.
- Build$49
- Grow$149
- Scale$849
Heartbeat is priced well at the bottom and awkwardly at the top. Fifty dollars a month for a custom domain, unlimited courses and events, mobile apps, a member directory, and a real checkout is the best entry-level package in this category, and the 14-day trial with no card required makes it genuinely low-risk to try. The problem is the shape of the curve. Member-count banding punishes free growth, the 5 percent Build fee is steep enough to matter as soon as revenue is real, and the leap from $149 to $849 is severe for a community that has grown members without growing income. The sweet spot is a Grow-tier community: a few thousand members, real revenue, 2.5 percent fees, and unlimited workflows for $149. Either side of that band, a competitor is usually cheaper.
Editorial verdict on each
Circle
Category LeaderCircle is the safe default for a community that is actually a business. Nothing else on a published price puts discussion, courses, events, live streaming, payments, affiliates, a custom domain, and native mobile apps in one product, and the company behind it is large, profitable, and shipping. Buy it if you are charging members and want the whole membership experience under your own brand without stitching five tools together. Do not buy it for a free community, because there is no free plan and the value proposition collapses without revenue to justify it. And go into the pricing with clear eyes: the honest monthly cost is the $89 plus a percentage of everything you sell plus Email Hub, and the exit cost is a discussion archive that will not move anywhere useful. Those are acceptable terms for a real membership business and bad terms for an experiment.

Heartbeat is the best answer for a specific and common situation: you have a community that behaves like a Discord server, and you want to charge for it without losing what makes it feel alive. Channels, threads, and voice rooms preserve the real-time energy, while courses, documents, workflows, and a checkout make it a business, and the custom domain on the $49 plan undercuts everyone. The catch is the pricing shape. Member-count bands punish free growth, the 5 percent entry fee is the steepest here, and the $149 to $849 cliff arrives on member count rather than on revenue. Buy it for a paid chat-first community in the few-hundred to few-thousand range, ideally sitting on the Grow tier where the economics are genuinely good. Look elsewhere if your community is free and growing, if you need SSO or public search visibility, or if a lightly funded startup holding your subscription revenue is a risk you would rather not take.
