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.

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.

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.

How do I back up my Lovable database?

Lovable Cloud stores backups you can restore from directly in the Database screen; for extra safety, also ask Lovable to export your data periodically.

Can I move from Lovable Cloud to Supabase?

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.

How do I view my database data?

Q: 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.

Short answer

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

Where your data lives

Every Lovable project using Lovable Cloud includes a managed Postgres database. You don't need a separate Supabase account to see what's in it.

Viewing data in Lovable Cloud

Open your project and go to the Cloud tab (sometimes labelled Backend).
Choose Database to browse tables, view and edit individual rows, and inspect columns.
Use the built-in SQL runner for anything a table view can't show, such as joins or aggregates.
Review security policies (RLS) from the same screen to see who can read or write each table.

You can also just ask in chat:

Show me the contents of the orders table, sorted by created_at descending

Lovable will query it for you and summarise the result.

If you connected your own Supabase project

If you connected your own Supabase project instead of using Lovable Cloud, view data in the Supabase dashboard's Table Editor, since that project is under your own account, not Lovable's.

What usually goes wrong

"I don't see a Cloud tab" — your project may not have Lovable Cloud enabled yet. Ask Lovable to "add a database" and it will provision one.
Table exists but looks empty — check you're looking at the right environment; some projects separate test and live data.
You can see the table but rows are missing — this is usually RLS filtering what a client-side call can see, not a UI bug. That's expected: the same policies apply if you query from the app.
