The core advice: don't add infrastructure before the app has earned it. Start by identifying what data must persist and who needs access, then choose between Firebase (best for mobile with low friction) or Supabase (best for relational data). Includes a framework of four questions to evaluate any AI-recommended service, a reusable prompt for scoping a first backend, and guidance on when local-only storage is sufficient for version one. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Should I use Firebase or Supabase for my first AI-built app? Choose Firebase for the lowest-friction mobile path when building iOS, Android, Flutter, or Expo apps needing quick auth, storage, and push notifications without operating servers. Choose Supabase when the app's data has clear relational structure, since it provides hosted Postgres, authentication, and storage, and works well with web, Expo, Flutter, and native mobile stacks. _Weighing Firebase against Supabase for a first build is exactly the kind of decision daily.dev helps developers research before committing._ ### Do I need a backend for my first version of an app? Not necessarily. A backend is needed only when a real user outcome requires information to persist after the app closes, belong to a specific user, or be shared with others; if version one is just proving interaction quality on one device, local storage is enough and cross-device sync, accounts, and cloud infrastructure can wait. _Developers scoping an early prototype can use daily.dev to weigh when local storage is enough versus needing a backend._ ### What questions should I ask before letting an AI add a backend service like analytics or payments? Ask what user outcome the service enables, what breaks or becomes manual without it in version one, what data it receives or stores, and what the smallest reversible implementation looks like. If the answers are vague, the service should be postponed rather than added just because it seems standard. _For developers vetting AI-suggested integrations, daily.dev surfaces practical framing like this before adding new dependencies._ ## Similar posts on daily.dev - [Supabase vs Firebase 2026: Honest Production Comparison](https://daily.dev/posts/supabase-vs-firebase-2026-honest-production-comparison-jnoxevtd1) · Alex CloudStar · 0 upvotes · 0 comments - [Vibe-coded AI Studio apps with Firestore, Firebase, Cloud SQL](https://daily.dev/posts/vibe-coded-ai-studio-apps-with-firestore-firebase-cloud-sql-5faawqfxm) · Google Cloud · 0 upvotes · 0 comments - [A backend for AI-coded apps](https://daily.dev/posts/a-backend-for-ai-coded-apps-rui5f5j5p) · Hacker News · 1 upvotes · 0 comments - [Supabase for Beginners](https://daily.dev/posts/supabase-for-beginners-zjlzdamsy) · freeCodeCamp · 11 upvotes · 0 comments --- Tags: [#backend](https://daily.dev/tags/backend), [#firebase](https://daily.dev/tags/firebase), [#vibe-coding](https://daily.dev/tags/vibe-coding), [#supabase](https://daily.dev/tags/supabase) [View this post on daily.dev](https://daily.dev/posts/the-first-backend-i-would-choose-for-a-beginner-ai-built-app-in-2026-dzjkylyhw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The First Backend I Would Choose For A Beginner AI-Built App In 2026","url":"https://daily.dev/posts/the-first-backend-i-would-choose-for-a-beginner-ai-built-app-in-2026-dzjkylyhw","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-first-backend-i-would-choose-for-a-beginner-ai-built-app-in-2026-dzjkylyhw"},"datePublished":"2026-07-15T07:29:27.409Z","dateModified":"2026-09-14T07:00:07.805Z","description":"A practical guide for beginners building AI-assisted apps on when and how to choose a backend.
