Can I vibecode Circle?

KINDA· weekend project

A members-only community for one small group is a forum with paid access: spaces, posts, comments, profiles, Stripe subscriptions and email notifications. An agent can build that over a weekend and skip Circle's 2% fee. What stays behind is everything that makes a community feel finished: native mobile apps with push, live streams and events, courses, workflows, SSO and dependable email delivery to thousands of members. No code moves your members for you either, and if you only want a discussion board, self-hosting Discourse is quicker than writing one.

Before you start

What you need on hand.

DifficultyAdvanced · Real infrastructure or OAuth work.

TimeA weekend; Stripe webhooks and email delivery take the longest

Claude Code, Codex or CursorAny of them can run the prompt.
Node.js 22better-sqlite3 compiles a native module, so build tools must be installed.
A Stripe accountUse test mode and the Stripe CLI until the webhook flow works.
SMTP credentialsA transactional provider's free tier is enough for a small community.
A public addressMembers must reach the site: a small VPS with HTTPS or a tunnel.

Before you buildCircle has no free plan, only a 14-day trial with no card. If all you need is discussion without payments, self-hosting Discourse needs less building.

1. Install one agent: Claude Code, Codex, Cursor.
2. Make an empty folder and open it in the agent.
3. Paste the prompt below, press enter, and answer its questions as it builds.

The prompt

Build me a small paid community site to replace Circle. Requirements:

- Node.js 22 + TypeScript: a Fastify server with server-rendered pages (Eta) and htmx for inline
replies and reactions. `npm start` serves http://localhost:4900.
- Storage: better-sqlite3 in ./data/community.db: members, spaces (public, members-only or paid),
posts, comments nested two levels deep, reactions, notifications and a Stripe subscription
table. Uploaded images go to ./data/uploads, 5 MB at most each.
- Members: email magic-link login (nodemailer, SMTP settings in .env), a profile with name, bio
and avatar, and one owner role who creates spaces, pins posts and removes members.
- Paid access: one monthly price in Stripe (STRIPE_SECRET_KEY and STRIPE_PRICE_ID in .env) with
Checkout and the customer portal. A webhook handles checkout.session.completed,
customer.subscription.deleted and invoice.payment_failed to switch access to paid spaces; verify
signatures and make every handler safe to run twice.
- Feed: newest first per space, 20 posts a page, markdown rendered with `marked` and cleaned with
`sanitize-html`; @name mentions notify the member.
- Email: notify on replies and mentions, plus a weekly digest from a `node-cron` job; every email
carries a one-click unsubscribe link signed with an HMAC token.
- Admin page for the owner: member list with CSV export, subscription status, delete a post or a
member, and a warning when the last webhook call failed.
- Single community, one owner. No accounts beyond Stripe and your SMTP provider, no telemetry,
local-first.
- Out of scope: mobile apps, live video, events, courses, direct messages, workflows, several
communities.
- README: Stripe test-mode setup with the Stripe CLI (`stripe listen`), exposing the site with a
tunnel or a small VPS, and a warning that sales tax or VAT on memberships is the owner's job.

Opens your agent with the prompt filled in, you press enter. Or copy it and paste it into an empty folder.

Then keep going

Next prompts, same folder.

The first prompt builds the core. Run these one at a time in the same folder to grow it into your own Circle.

Add a Circle importer to the community site in this folder. Requirements:

- A command `community import-circle` that takes the members CSV from Audience > Export CSV and
  the data export Circle support emails (members, spaces, posts and comments CSV files).
- Create members from the email, first and last name, join date and tags columns without sending
  any email; map spaces by name and keep the original post and comment timestamps and authors.
- Authors who are not members become a placeholder member named "Former member".
- Print a summary of what it would create and ask before writing; running it twice must not
  duplicate anything.
- Update the README with the two Circle export steps.

Add events to the community site in this folder. Requirements:

- An events space type: title, description, start time with timezone, duration and a meeting URL.
- RSVP button for members; the owner sees the attendee list with a CSV download.
- Send a calendar invite (.ics via `ics`) on RSVP and a reminder one hour before.
- Show times in each member's timezone, set in their profile.
- Update the README.

Add a preview mode for paid spaces in the community site in this folder. Requirements:

- The owner can mark individual posts in a paid space as public preview.
- Logged-out visitors see previews with a join button that starts Stripe Checkout; other posts show
  only the title and a lock.
- Previews carry Open Graph tags so shared links look right.
- Update the README.

What you lose

Native iOS and Android apps with push notifications; a branded app is a Circle Plus feature
Live streams, rooms and event pages with RSVPs
Courses, workflows and automations, plus the SSO and API connections
Hosted spam control, backups, uptime and email delivery for every member
Member analytics and moderation queues that someone else maintains

Why people still pay

Community owners want to sell memberships, not run a forum. Circle puts spaces, events, courses, payments and email behind one login, and its 2% fee costs less than the hours it takes to keep a self-built stack patched, deliverable and working on phones.

Leaving Circle

Take your data, then cancel.

1 · Take your data out of Circle

1Members: open Audience > Audience, pick a tab, apply filters if you want a subset, then More > Export CSV. The file is emailed to your admin address and holds names, emails, join dates, tags, profile fields, engagement counts and last-active dates.
2Posts and comments have no self-serve button: an admin emails support@circle.so for a data export, delivered as CSV files of members, spaces, posts, comments and events. Uploaded media isn't included.
3Event and live-stream attendee lists download as CSV from each event's People or Participants tab.
4Subscriptions and transactions have their own export article in the help center (not read for this entry); the card data and customer records live in your own Stripe account.

2 · Cancel Circle

1Click the community name, open Settings > Subscription > Plans, go to the Manage Billing tab, scroll to the bottom and click End your subscription, then confirm.
2The plan is set to end with the billing cycle, so the community stays active until then; email support@circle.so to deactivate it immediately.
3Cancelling the plan does not cancel your members' paywall subscriptions: cancel and refund those yourself, since they run through your Stripe account.
4After the plan ends, community data is typically removed after 90 days: request the support export before that.

Circle refunds within 30 days of the original start date; downgrades and unused time are not refunded.
A trial needs no card, so you can let it lapse; the data is typically removed 90 days after expiry.
Your Stripe account stays connected after cancelling: close that integration once member subscriptions are settled.
Circle's own help article says re-importing an export into Circle is hard, so treat the CSV files as an archive and keep a copy of your member emails before you announce the move.

Billing: The pricing page quotes every plan as based on annual billing. The help center says monthly and annual billing both exist and are chosen on the Plans page, but it doesn't give monthly prices. Upgrades apply at once with unused time credited; downgrades start at the end of the cycle with no credit. A 30-day money-back guarantee runs from the original start date, and renewals or plan changes don't reset it. Prices exclude taxes.
Hidden costs: A 0.5-2% transaction fee on paywall sales, on top of Stripe's own fees. Extra admins cost $10 a month each, extra moderators $20 a month per 10 and extra spaces $20 a month per 10. Email Hub is a separate add-on at $99 a month for 10,000 contacts, with the first 30 days free. AI credits beyond the monthly allowance are $10 per 1,000.

No free plan; a 14-day trial needs no credit card.

Kinda. The core is a weekend build with the prompt on this page, but real gaps remain: Native iOS and Android apps with push notifications; a branded app is a Circle Plus feature, Live streams, rooms and event pages with RSVPs.

About $89 a month on the Professional plan, $1,068 a year (checked 2026-10-19).

Native iOS and Android apps with push notifications; a branded app is a Circle Plus feature; Live streams, rooms and event pages with RSVPs; Courses, workflows and automations, plus the SSO and API connections; Hosted spam control, backups, uptime and email delivery for every member; Member analytics and moderation queues that someone else maintains. If any of those matter to you, keep paying.
