What this skill does
Managed App Backends Use this skill to choose between managed app-backend platforms when the real decision is not just "which database," but which product backend bundle should own auth, data, realtime, storage, server-side functions, and early operational tradeoffs. This skill covers: SQL-first and NoSQL-first managed backend platform choice auth, permissions, and data-ownership model tradeoffs realtime sync and offline behavior differences self-hosted versus hosted operational tradeoffs migration and exit paths when a platform stops fitting Quick Reference Need Default path Notes ------ -------------- ------- Postgres-first product backend with RLS, auth, storage, and realtime Supabase Best fit when SQL portability and browser-safe Postgres workflows matter TypeScript-first reactive backend with durable workflows Convex Best fit when live subscriptions and function-centric app logic matter more than SQL Mobile/offline-first app with mature client SDKs Firebase / Firestore Strong default when device sync and mobile SDK ergonomics dominate Self-hosted full backend bundle with auth, DB, storage, and functions Appwrite Good fit when self-hosting is a first-order requirement Small single-binary app backend or internal tool PocketBase Good fit for prototypes and lightweight deployments, not the default for high-criticality systems; still pre-1.0 — verify current version and breaking-change posture before betting production on it Pure Postgres host without a bundled auth/storage/realtime layer Neon or PlanetScale Postgres Use when you want serverless Postgres (branching, scale-to-zero) but plan to build auth/storage/realtime yourself or already own them elsewhere; not a like-for-like Supabase substitute Complex compliance, bespoke domain logic, or multi-service boundaries ../software-backend/SKILL.md + ../software-database-design/SKILL.md Use custom services when you need stronger control than a BaaS can provide Picking the compute host (Vercel, Fly.io, Railway, Render, …
