What is Lovable Cloud?

Lovable Cloud is a Supabase backend (Postgres database, authentication, storage, edge functions) that Lovable provisions and manages for your project automatically, with no separate account or dashboard needed.

When should I use Lovable Cloud?

Use Lovable Cloud for most new projects needing a backend — it's the fastest path with no separate account; connect your own Supabase project instead if you already have one, need direct dashboard access, or must integrate with existing Supabase infrastructure.

How do I connect Supabase to Lovable?

In your Lovable project, open the Supabase integration and authorise Lovable to connect to an existing Supabase project (or create a new one), then Lovable can read and write to it the same way it does with Lovable Cloud.

How do I create a database in Lovable?

Ask Lovable to set up Lovable Cloud (or connect your own Supabase project) and describe the tables you need — Lovable provisions the Postgres database and creates the tables from your description.

How do I create database tables?

Describe the table's purpose and fields in plain language to Lovable — including which fields are required, their types, and any relationships to other tables — and Lovable generates the table with appropriate row-level security policies.

How do I view my database data?

Open the Cloud tab (or ask Lovable) to browse tables, edit rows and run SQL directly inside your project — no separate Supabase login needed.

Why isn't Lovable saving data?

Most commonly this is a missing or misconfigured RLS policy blocking the insert/update, an unconnected database, or a form that never calls the backend at all.

Why is Supabase returning a 403 error?

A 403 means Row Level Security blocked the request — the current user's role doesn't match any policy allowing that read or write on that table.

What is Row Level Security (RLS)?

RLS is a Postgres feature that restricts which rows a query can see or change, enforced per-row on the database itself rather than trusted to your app's code.

Do I need RLS on my Lovable app?

Yes, for almost any app with user data, private content or logged-in users — without RLS, anyone can read or write any row via the database's public API.

How do I fix RLS errors?

Identify which operation and role is being blocked, then ask Lovable to add or correct the specific policy for that table rather than disabling RLS.

Why can users see other users' data?

Almost always a missing or too-permissive RLS policy — either RLS isn't enabled on the table, or a policy allows reading rows regardless of who owns them.

How do I safely store API keys?

Store keys as secrets in your backend (Lovable Cloud/Supabase) and call the third-party API from a server/edge function — never put keys in front-end code.

How do I use environment variables?

Use `VITE_`-prefixed variables only for non-sensitive, public values baked into the front-end build; use Secrets for anything sensitive that a server/edge function needs.

What are Supabase Edge Functions?

Edge Functions are small serverless backend functions that run outside the browser — used for anything requiring a secret key, a third-party call, or logic that shouldn't be trusted to the client.

When should I use an Edge Function?

Use one whenever your app needs a secret key, must call a third-party service, or needs logic that shouldn't be trusted to run in the user's browser.

How do I upload and store files?

Ask Lovable to add file uploads and it will wire up storage in Lovable Cloud (or your connected Supabase project), including an upload UI and access policies for the files.

Can I move from Lovable Cloud to Supabase?

Last checked 31 Aug 2026

Short answer

Yes — Lovable Cloud is a Supabase backend under the hood, and Lovable supports connecting your own Supabase project instead, though moving existing data across takes an export/import step.

Yes, this is a supported path

Lovable Cloud is itself built on Supabase, managed by Lovable so you don't need a separate account. If you outgrow that setup — you want direct dashboard access, specific Supabase add-ons, or to manage billing yourself — you can connect your own Supabase project instead.

What changes

	Lovable Cloud	Your own Supabase
Account	Managed by Lovable, no separate login	Your own Supabase account
Dashboard access	Ask Lovable to make changes	Full Supabase dashboard access
Billing	Part of your Lovable plan/credits	Separate Supabase billing
Database/auth/storage/functions	Included	Included, same underlying tech

How the move works

Create your own Supabase project if you haven't already.
Ask Lovable to connect that Supabase project to your app.
Recreate your schema, RLS policies, and storage buckets in the new project (or export/import them, since it's the same underlying Postgres).
Migrate existing data across — Lovable can help generate the export/import steps, but plan for some manual verification since this touches real data.
Update any secrets/edge functions that reference the old backend.

I want to move this project from Lovable Cloud to my own Supabase project. Walk me through connecting it and migrating my existing tables and data.

What usually goes wrong

Assuming the move is instant — schema, policies, storage and secrets all need to be recreated or migrated, not just "reconnected".
Forgetting that RLS policies need re-checking after the move, since a fresh Supabase project starts without them.
Losing track of which project is "live" mid-migration, causing writes to go to the wrong place temporarily.

If this migration involves data you can't afford to get wrong, it's a reasonable job to hand to PromptSites.com rather than doing it live on a production app.
