TypeScript派は迷わずConvex、Supabase Realtime + Firebase Realtimeより上位Reactive Queries + ACID Transactions、Pro Real-time真本気派 必選、(2)$25/月Pro($300/年)はSupabase($25/月) + Firebase Pay-as-go同水準、TypeScript Native + Reactive + ACID + Built-in AI + Components Library で正当化、Mainstream Free Tier(1GB DB + 5GB Bandwidth + 1M Function Calls)で Pro Indie Hacker Bootstrap対応、(3)Reactive Queries = Frontend SQL Query → Realtime UI Update自動、Firebase/Supabase Realtimeと完全別Pro UX、Pro Real-time App Pro Workflow革命、Pro Real-time真本気派 必選機能、(4)ACID Transactions + Multi-Document Transaction = Firebase NoSQL + Supabase PostgreSQL基本ACID と異なる Pro Custom Engine ACID + Multi-Document Pro Data Consistency、Pro Distributed System派 真価発揮、(5)Convex Components(Auth/Email/Stripe/AI/Sentry/Discord) + Built-in AI Models = Pro Stack統合 + Pro Indie Hacker Bootstrap時短、Supabase OSS + Firebase Mainstream にない Pro UX強み。\n\n## 関連用語との違い\n\nSupabase: 2020 Open Source + PostgreSQL Native + Vercel統合・$25/月Pro。Convex(2022 + Closed Source Backend + TypeScript Native + Reactive + ACID)と用途別、Open Source + PostgreSQL = Supabase、TypeScript + Reactive + ACID + Real-time = Convex。\n\nFirebase: 2011 Google + Firestore NoSQL + 累計400万+。Convex(TypeScript Native + Reactive + ACID Transactions + 5万+)とMainstream + Google Eco vs Pro TypeScript + Real-time + Closed Source、用途で完全別、Mainstream = Firebase、Pro TS Real-time = Convex。\n\n## よくある質問(FAQ)\n\nQ1: Supabase と どう違う?\nA: Supabase(Open Source + PostgreSQL + Vercel統合 + 100万+) vs Convex(Closed Source Backend + TypeScript Native + Reactive Queries + ACID + 5万+)、Open Source + PostgreSQL = Supabase、Pro TypeScript + Real-time + ACID = Convex、用途で分岐。\n\nQ2: Reactive Queries 効果?\nA: SQL Query Subscription + Realtime UI Update自動 + React Native対応で Frontend SQL Query → Realtime UI Update自動 + Pro Real-time App Workflow革命、Firebase + Supabase Realtimeと完全別Pro UX、Multiplayer Game + Collaborative Editor + Cursor + Pro Real-time真本気派 真価発揮。\n\nQ3: Self-hosted 不可?\nA: Convex Backend はClosed Source(Pro Custom Engine + ACID + Reactive Queries + Pro信頼性)、TypeScript Client SDKのみOpen Source、Self-hosted不可 + Cloud Convex Pro前提、Open Source + Self-hosted派 はSupabase/PocketBase/Appwrite推奨、Convex はCloud Pro Pro Real-time専業。\n\n## まとめ\n\n- 2022-05 Convex Inc、Realtime DB業界\n- TypeScript Native + Reactive Queries + ACID\n- Built-in AI Models + Components +
