How are these tools ranked?

Each tool is scored out of 100 on fit, vibe-coder friendliness, output quality, pricing, ecosystem, momentum and code ownership, using desk research of official docs and pricing pages. Affiliate status never affects scores.

Supabase is standard Postgres with auth and storage, a natural fit for Lovable’s React apps, and you keep control of the database if you move hosting later.

Start with what Lovable includes

Lovable Cloud is Lovable’s built-in backend: database, storage, compute and realtime, paid from your Lovable credit balance. Free workspaces get 20 Cloud credits a month. Lovable’s docs say backend services pause when your workspace runs out of credits, and that the data stays safe but you can’t access or export it until the services run again.

When to use an external backend

Consider your own backend if you want to control the bill directly, plan to move the frontend off Lovable, or need Postgres access from other tools. Lovable supports connectors and calling any API, and two-way GitHub sync, so the code can keep working after you leave.

Supabase

Standard Postgres with auth, storage and realtime. Free: 50,000 MAU, 500 MB database, 2 projects (paused after a week idle). Pro from $25/mo. The closest match to how Lovable apps are built (React plus a Postgres backend).

Convex and Firebase

Convex is a TypeScript-first reactive backend. Firebase pairs Firestore (NoSQL) with Google’s auth and mobile tooling, and its Spark plan is no-cost within limits. Both take more manual wiring from a Lovable project than Supabase does.
