Creator and commerce decision
Circle
A competent developer can build a narrow community product (discussions, memberships, payments) but reproducing Circle’s AI features, branded native apps, migrations, and compliance/scale would be costly; keeping the hosted product is reasonable if you need those capabilities.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Circle alternatives, with the arithmetic →
What a replacement has to do
- Members sign up → create/read/write posts and comments → manage membership access (paid/free) → host events / livestreams
What it still won’t have
- Branded native iOS & Android apps (custom app build & app-store listing)
- Managed AI Agents, AI workflows and included Circle AI credits
- Built-in Email Hub with 10k contacts and migration services
- Enterprise compliance & certifications handled (SOC 2, PCI processes)
- Platform scalability, uptime SLAs and migration assistance
What remains hard
- Compliance and regulation

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted community platform using Next.js (React) + PostgreSQL + Node/Express + Stripe for payments. Implement: user auth and profiles (email sign-up, roles), spaces with per-space permissions, discussion feed with posts and threaded comments and media uploads (store files on S3), searchable index (Elasticsearch or Postgres full-text), membership gating using Stripe subscriptions, event scheduling with embeddable live stream links, and an admin analytics dashboard (member counts, active posts). Out of scope: native mobile apps, ML/AI agents, advanced workflows, enterprise SOC2 attestation. Include error handling, input validation, tests for auth, payments, and posting, and deployment scripts (Docker + Terraform) for one small cloud VM, managed Postgres, and S3-compatible storage.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
