The best backend and hosting for vibe-coded apps

Once an AI builder generates your app, it needs a database, auth and somewhere to run. Quick answer: Supabase for the database and auth, Vercel for front-end hosting, Railway for backends that outgrow serverless.

Scores are editorial estimates from public research (2026-10), not yet hands-on tested. We'll update them as we run each tool through our three standard builds. Methodology.

Each platform in detail

Supabase · 89.5/100

Supabase is the backend most AI app builders reach for: Postgres plus auth, storage, realtime and edge functions, with first-class integrations in Lovable, Bolt and v0. It's open source and portable, so you aren't locked in. Pro starts at $25 but compute is billed per project, and getting row-level security right matters for safety. For vibe coders, it's the clear backend recommendation.

Pros: Postgres, auth, storage, realtime, edge functions; Native integration in Lovable, Bolt, v0; Portable, open source. Cons: Compute billed per project on top of plan; Requires some SQL/RLS understanding.

Vercel · 87.5/100

Vercel is the go-to host for Next.js and modern front ends, with instant git-based deploys, preview URLs for every pull request, edge functions and a strong AI SDK. Its tight integration with v0 makes it a natural endpoint for vibe-coded apps. The free Hobby plan is for non-commercial use only, and Pro usage can grow costly at scale, though spend caps help. The polished default for front-end hosting.

Pros: Best-in-class Next.js deploys; Preview deployments per PR; v0 and AI SDK integration. Cons: Hobby is non-commercial only; Usage costs can climb at scale.

Railway · 81.0/100

Railway makes deploying backends, workers and databases almost as easy as deploying a static site: connect a repo or template and it provisions services with sensible defaults. It suits apps that outgrow serverless, like Python APIs or bots built with coding agents. Plans start at $5 a month with usage-based billing; there's no permanent free tier. A favorite among developers who want Heroku-style simplicity.

Pros: Deploy any backend/DB in clicks; Great developer experience; Usage-based, fair pricing. Cons: Not truly free; Less beginner hand-holding.

Firebase · 78.5/100

Firebase is Google's mature app backend with Firestore, authentication, hosting, functions and excellent mobile SDKs, plus AI tooling through Firebase Studio and Gemini. The free Spark plan is generous, and Blaze is pure pay-as-you-go. Its NoSQL data model and Google lock-in make it less portable than Supabase, and usage-based bills can surprise you. Best for mobile-first apps or teams already on Google Cloud.

Pros: Mature, Google-backed; Great mobile SDKs; Firebase Studio AI tooling. Cons: NoSQL lock-in; Usage bills can be unpredictable.

Netlify · 78.0/100

Netlify pioneered git-based deploys for static and Jamstack sites and remains a simple, reliable host with built-in forms, serverless functions and deploy previews. A $9 Personal plan makes it cheaper than Vercel for small commercial projects. It's less optimized for cutting-edge Next.js features, and its momentum has slowed relative to Vercel. A solid, budget-friendly host for sites exported from AI builders.

Pros: Simple git deploys; Cheap Personal tier; Forms, functions built in. Cons: Less Next.js-optimized than Vercel; Momentum slower.
