Verdict
A community chat space with an integrated events calendar — members can see and RSVP to scheduled community events alongside regular channel discussion — is a real weekend-to-week build combining this catalogue's Slack Pro-style chat core with a simple calendar and RSVP feature. What doesn't survive: Heartbeat's polish across native mobile apps and years of community-moderation tooling.
Exhibit A — The prompt
Received on31.07.2026Build a community chat space with an integrated events calendar, extending this catalogue's Slack Pro entry's chat core with scheduled events and RSVPs. Use Next.js/TypeScript with WebSockets for live chat and Postgres for durable storage, the same base as the Slack Pro build. Add an events feature: any member, or just owners, your choice, can create an event with a title, description, date and time, and optional external link for a video call hosted elsewhere, since in-app video hosting is out of scope. Show upcoming events in a simple calendar or list view visible to all members, with an RSVP button that tracks who's attending. Send an email reminder to RSVP'd members a configurable time before the event, such as one hour before, via a transactional email provider. Keep the channel-based chat, threads, and reactions from the Slack Pro build's core as the space's primary daily-use surface, with events as a secondary feature layered on top, not the other way around. Do not build native mobile apps, in-app video or voice hosting for events, or advanced moderation tooling — those are out of scope. Requires hosting, a domain, and a transactional email provider for event reminders.Opening prefills the prompt — press enter to run it.
Exhibit B — What you lose
- B.1 native mobile apps
- B.2 years of community-moderation tooling
- B.3 video/voice infrastructure for hosting events directly in-app
- B.4 member directory and profile richness
Prior art
Exhibit C — Why people still pay: network, moderation, and communication infrastructure
Chat plus a calendar is buildable; running that reliably for a community that expects mobile notifications and in-app event hosting, with moderation tools mature enough to trust, is the ongoing product work.
Questions
How is this different from the Slack Pro build in this catalogue?
It adds a scheduled-events calendar with RSVPs and reminders on top of the same channel-chat core — useful specifically for a community that runs recurring events, not just ongoing discussion.
Does it host video calls for events directly?
No — events link out to a video call hosted elsewhere, any existing video-conferencing tool. In-app video hosting is out of scope.
Will members get a mobile app notification for events?
No native mobile app here — reminders go out by email instead, which is a real step down from a polished mobile push notification.
What does it cost to run?
Hosting, a domain, and a transactional email provider's free tier for reminders — typically a few dollars a month for a small community, with no per-member fee.
