The short answer
Editorial assessmentSlack compared with Heartbeat
Heartbeat exists in large part because professional communities outgrow Slack. It offers chat that feels familiar to a Slack user, plus permanent history, events, courses, and a checkout, on a flat plan rather than per member. If your Slack community is working but the 90 day wall and the lack of a payment layer are the problems, Heartbeat is the closest shaped replacement.
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.
Choose Slack if
Professional and industry communities under a couple of hundred members whose value is live conversation and access rather than an accumulating archive, especially where members are software or business people who already live in Slack all day and will not install anything new.

| Free trial | 14 days, no credit card required | The free plan serves as the evaluation path; paid plans are self serve |
| Best for | 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. | Professional and industry communities under a couple of hundred members whose value is live conversation and access rather than an accumulating archive, especially where members are software or business people who already live in Slack all day and will not install anything new. |
| Setup time | 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. | Minutes to a workspace, a day to a well organized one. The real work is deciding channel structure and writing an onboarding flow in Workflow Builder, because Slack gives new members no guidance by default. |
| Learning curve | 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. | Effectively zero for professional members, who already use it daily. Moderate for operators only because Slack's admin tooling assumes an IT context rather than a community one, and much of what a community manager wants simply is not there. |

Strengths and limitations
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.
Slack
Strengths
- Zero adoption friction with professional audiences. Software, product, and business people already have Slack open all day and will join a workspace without installing anything or learning anything.
- The best threading model in this category. Replies branch cleanly under a message instead of flooding a channel, which keeps a busy community readable in a way Discord struggles with.
- Search quality is genuinely good, with filters by person, channel, and date, and better than every free alternative here within the window it can see.
- Slack Connect on Pro shares channels with up to 250 external organizations, which is the strongest legitimate community use case Slack has for a B2B company.
Limitations
- The 90 day history limit on the free plan destroys the archive, which is the single largest source of long term community value, and Discord does not have this problem at the same price.
- Per member pricing makes upgrading impossible at community scale. A thousand members on Pro is $7,250 a month, or roughly eighty times Circle.
- No commerce layer whatsoever: no checkout, no memberships, no entitlement, so charging for access always means a third party invite tool bolted onto Stripe.
- No moderation queue, no spam classifier, and no equivalent of AutoMod. Slack assumes a workspace is full of colleagues.
Pricing compared
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.
Slack
Per user per month subscription designed for employees, with a permanently free tier limited by message history and app count. There is no community pricing, no member tier, and no commerce layer.
- Free$0
- Pro$8.75
- Business+$15
- Enterprise+Custom
Free Slack is worth using and paid Slack is not, at least not for a community. What the free plan gives you is genuine: unlimited members, unlimited channels, the best threading model in this category, strong search within its window, mature apps, a huge integration directory, and a professional audience who already have it open. What it takes away is the thing that makes a community compound. Ninety days of history means the archive never accumulates, and the members who answer the same question for the fourth time will eventually stop. Upgrading is not a fix but a different problem: at $7.25 per member per year Slack is charging you employee prices for people who are not employees, and a thousand member community would pay $87,000 a year for what Discord provides free and Circle provides for about $1,100. The correct read is that Slack is an acceptable free venue for a small professional community that trades on access rather than on archive, and a bad idea for anything else.
Editorial verdict on each
Heartbeat
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.

Slack is where a great many professional communities live and almost none of them chose it. As a free venue for a few hundred senior people who already have it open, it is legitimately good: threading is the best in this category, search is strong, adoption friction is zero, and Slack Connect handles customer and partner channels better than anything else here. As a community platform it has two disqualifying flaws. The free plan hides everything older than 90 days, so the archive that makes a community valuable over time never accumulates, and Discord does the same job for free while keeping every message forever. And upgrading charges employee prices for people who are not employees: a thousand members on Pro is $7,250 a month, roughly eighty times what Circle costs to host the same community with permanent history, courses, events, and a checkout. There is no commerce layer at all, so charging for access means a third party invite tool bolted onto Stripe, with the fragility that implies. Use free Slack for a small professional group that trades on access. For anything that should still be useful in two years, move to Discord if you want free, Discourse if you want found, and Circle or Heartbeat if you want paid.
