The codebase was well documented and AI Agent friendly and security has been taken as a foundational component, not an afterthought as in many "vibe coded" products.

The honest version
Heartbeat deserves the honest credit first. It is a well-scoped product with custom domains on every plan, real monetization, and built-in automations, the closest feature-for-feature rival Seedly Communities has.
The structure is the story. Member caps per tier, 350 on Build and 5,000 on Grow, with unlimited only at $849 a month. Revenue fees of 5%, 2.5%, or 1.25% stacking on Stripe by tier. A branded app locked at the top tier, while the app that exists rates around 3.5 stars, with documented reports of white screens, phantom notification dots, and posts that appear published but never publish. Export means filing a support ticket.
When the feature lists match this closely, the comparison collapses to the business model. Rent the toolkit forever, with caps and fees, or buy the toolkit once for $399.

Competitor pricing, fees, and review scores verified September 2026 from vendor pricing pages and cited third-party sources. Plans change often, so confirm current details on each vendor's site. Seedly Communities is a one-time license plus your own hosting on accounts you control.
The math that matters
Heartbeat's Grow plan is $149 a month, $8,940 over five years, and it caps you at 5,000 members. Build is $49 a month, $2,940 over five years, capped at 350 members with a 5% revenue fee. Unlimited members their way is $849 a month, $50,940 over five years. Unlimited members our way is $399, once. That is the starkest per-member math in the category.
The fees stack too. At $30,000 a year in member revenue on Grow, the 2.5% cut is about $750 a year on top of rent, before Stripe's own fees.
Seedly Communities has no member, seat, or admin caps, no revenue fee, and payments run through your own Stripe. Your ongoing cost is your own Convex and Vercel hosting. Bought together with Seedly CRM in one checkout, it is $249.
The real thing
Real-time chat, DMs, reactions, and typing indicators, with unlimited members and 0% fees, bought once.
The whole point
The caps are the quiet upgrade engine. Member 351 on Build is not a milestone, it is an invoice. On software you own, growth costs you nothing extra, which is the whole reason to own a toolkit you already like.
And the rent does not buy reliability. The 3.5-star app reports, white screens and posts that never publish, come from paying customers. Our mobile story is honest and modest, responsive web plus Capacitor shells you configure, but nothing about your community waits on a landlord's bug queue.
Don't take our word for it. Take theirs.
Every review 5 out of 5 on Trustpilot. These are Seedly owners on the code they were handed and whether I stood behind it. I build Seedly Communities the same way.
Read every review →Getting out
Heartbeat's export runs through support tickets, posts, comments, docs, and members per their help docs. Request everything before you cancel, while the account still answers.
Then the standard manual move. Invite members through Seedly's invite links and email invites, re-seed your cornerstone content, and re-anchor subscriptions on your own Stripe with fresh opt-ins. No importer exists on our side.

Straight talk
Heartbeat gives you managed hosting, built-in automations, and a real if rough dedicated mobile app today, with zero deploy work. If you will never touch a deploy dashboard, rent theirs.
If you can spend one setup weekend, own ours.

Questions, answered
Less than you would think on the toolkit, feed, chat, courses, events, live, payments, both sides have them. The differences are the deed, the caps, and the fees. Heartbeat rents you the toolkit with member caps and a revenue cut. Seedly sells you the source once, with unlimited members and 0% fees.
Yes. Twelve engagement automation types ship built in, welcome posts, at-risk member outreach, abandoned-cart recovery, onboarding drips, streak recovery, event follow-ups, and more, configured from the admin Workflows screen without code. Outbound webhooks and the REST API are there too for wiring into external tools.
On Seedly, nothing, there are no member caps anywhere in the code. On Heartbeat's Build plan, member 351 is the moment you upgrade tiers, which is how caps are designed to work.
Seedly ships responsive web plus Capacitor iOS and Android shells you configure and submit yourself, there is no managed native app service. Heartbeat has a dedicated app today, currently rated about 3.5 stars with documented bugs. Both halves of that sentence are true, so weigh them honestly.
Your own Convex, Vercel, and Stripe accounts, plus Daily.co for live video and SendGrid or Postmark for email plus a guided deploy weekend. It is source you own, deployed on infrastructure you control, with no tier ladder waiting as you grow.
Buy the source once. Run it yourself. It is yours for good.

One payment. Unlimited members. 0% platform fees.
