Circle
A weekend of work, and real gaps remain.
A community platform: spaces for discussion, live events, courses and paid memberships, under your own domain. It is where a creator or a company puts the audience that would otherwise be scattered across a chat server and an email list.
Build me a private community space that I can leave with everything. STACK - Astro with a Node adapter, SQLite via better-sqlite3 - Server-rendered HTML, no frontend framework, no mobile app STRUCTURE - Spaces, threads and replies, with Markdown, mentions, reactions and file attachments - Per-space visibility: public, members, or invite-only ACCOUNTS - Email magic-link sign-in, so there are no passwords to leak - Roles: member, moderator, admin THE DIGEST, WITHOUT WHICH NOBODY RETURNS - A daily or weekly email of new activity, sent through a relay - One-click unsubscribe, and a preference that survives account changes MODERATION - Report a post, a moderation queue, and soft-hide rather than delete so the record survives - A rate limit on new accounts posting links SEARCH - SQLite FTS5 across threads, scoped to the spaces the reader can actually see THE EXIT - An export command producing every thread as Markdown plus a member CSV - The README should say that this exists because being locked in is what you are leaving Include a README on the magic-link expiry, the digest schedule and the export format.
What you lose
- Members, who do not migrate — a community is the one asset that genuinely cannot be exported
- Mobile apps and push notifications, which is how most members actually return
- Live streams, events and courses bundled into the same space
- Paid memberships with billing, dunning and access control already wired together
- Moderation tooling and spam handling, which you will need on day one and not before
If you would rather not build
- Discord, if you accept renting the community outright

Why this verdict
our own opinion · changed only by a person
42/100
Verdict kinda at 42: a forum is a well-understood build and an agent gets you a good one in a weekend. The score stays low because the value of Circle is the members and the habit, and neither ships with the code.
