Trivia Flow
A competent developer can build a usable self-hosted trivia host (join codes, realtime play, scoring, analytics) but cannot cheaply reproduce TriviaFlow's large curated question bank and content updates, so running your own replacement is viable for core hosting needs but not a full feature-for-feature swap.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Run a live trivia session: create or load question sets, start a session, have players join via QR/join code, collect answers in real time, auto-score, show leaderboards and post-game analytics.
What it still won’t have
- The vendor's 50,000+ curated question library and frequent content updates
- Priority content updates and curated premade packages
- Any proprietary anti-cheat heuristics and platform polish/UX developed by TriviaFlow
What remains hard
- Proprietary data
50,000+ curated trivia questions

Runnable build prompt
Build a self-hosted live trivia app using Next.js (React) + Node.js API, Postgres for questions/sessions, and Supabase or Pusher for realtime. Core features in scope: host control panel and presentation view, mobile join via QR code/join code, realtime answer collection and leaderboard updates, question CRUD editor supporting multiple question types and rounds, an automatic scoring engine with an LLM-backed endpoint toggle for 'type the answer' grading (or fuzzy-match fallback), and post-game analytics (per-question stats, session export). Out of scope: importing a commercial 50k question library and premium content updates. Include error handling, input validation, basic tests for API endpoints and scoring logic, and deployment instructions (Docker + simple VPS or managed Postgres).

- 3/3 assessment runs agreed+4
- Hard moats found in the evidence-3
- Evidence score56
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.
