Scheduling and meetings decision
Crowdcast
A technical user can build a narrow Crowdcast replacement (registration, RTMP ingest, chat/Q&A, replay, Stripe payments) using existing OSS components and managed streaming, but reproducing Crowdcast’s production-grade streaming scale, polished in-browser studio, integrations catalogue, and operational reliability is substantial and likely impractical for one person to match.

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.
What a replacement has to do
- Accept registrations, ingest a live video stream, present slides/video, enable chat/Q&A/polls, record and publish replay, and sell tickets via Stripe.
What it still won’t have
- Polished in-browser live production studio (overlays, cueing, built-in video playback)
- Scale and reliability inherited from a production streaming backend
- Built-in multistreaming to third-party platforms and Zapier catalogue
- Two-week free trial and vendor support
- Integrated channel/follower system with push/email notifications
What remains hard
- Infrastructure at scale
After bringing together over 10 million attendees , we’ve re-designed and engineered a groundbreaking new experience.

Paying is—cheaper in year one.

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 live event platform using Node.js (Express), Postgres, Redis, React, and an RTMP-capable ingest service (e.g., NGINX-RTMP or a managed ingest). Include: 1) public event pages with one-click registration and CSV export, 2) RTMP ingest endpoint + HLS playback and server-side recording stored in S3-compatible storage, 3) real-time chat, upvotable Q&A, and polls (WebSocket via Redis pub/sub), 4) Stripe integration for paid tickets and per-event pricing, 5) replay serving on the same event URL, 6) basic analytics (registrations, live attendees, poll results). Out of scope: building a custom browser-based multi-camera production studio, large-scale multi-region CDN architecture, and mobile apps. Provide error handling, input validation, automated tests for APIs and front-end components, and deployment instructions (Docker + terraform for infra).

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.
