    Lovable rescue

    Built it in Lovable, can't get it over the line?

    If Lovable built your app fast and then stopped — sign-in fails on your real domain, users can somehow see each other's data, the edge function works in preview and 500s in production, or the migration lives only in the Supabase dashboard — AI Cubed audits the project in two business days and takes it to production. You keep Lovable, the repo and everything in it. Most rescues finish in two to four weeks.

    Lovable's strength is that it makes a real Supabase-backed app appear from a description. Its weakness is that it makes the app look finished long before it is safe. The gap is not a Lovable bug. It is the part of software that no description can cover.

    Sounds familiar?

    • "Sign-in works in the Lovable preview and breaks on my custom domain."
    • "I turned on RLS because Lovable told me to, and now the app shows nothing."
    • "Or worse — I didn't, and I just realised any logged-in user can read every row."
    • "The edge function works when I test it and fails when a real user hits it."
    • "I changed a table in the Supabase dashboard and now the app and the database disagree."
    • "Google can't see any of my pages. The site is one empty HTML file and a bundle."
    • "Every prompt to fix one thing regenerates a component I'd already fixed."

    What breaks in Lovable apps specifically — and what we do

    Lovable apps share a stack — React and Vite, Tailwind and shadcn/ui, Supabase for auth, Postgres, storage and Deno edge functions — so they share failure modes. This is our Lovable-specific checklist.

    Lovable + Supabase: the recurring failures
    What breaksWhy it happens in LovableWhat we do
    Row-level security (RLS)Lovable creates tables quickly; policies are either missing (data is public to any logged-in user) or written as `USING (true)` so the demo works.Write per-table policies keyed to `auth.uid()`, test them with two real users, and add a policy-coverage check so a new table can't ship open.
    Auth on a custom domainSupabase Site URL and redirect allow-list still point at the Lovable preview URL; OAuth providers still have the old callback.Set Site URL and redirect URLs per environment, update every OAuth provider's callback, test magic link, OAuth and password reset on the real domain and on a phone.
    Edge function secrets and errorsSecrets set in the Lovable UI aren't set in the Supabase project; functions swallow errors and return 200 with nothing.Move secrets to Supabase function secrets per environment, add real error responses and logging, add a timeout and a retry where an upstream API is called.
    Service-role key in the clientA prompt asked for an admin feature and the model reached for the key that makes it work.Rotate the key, move privileged operations into an edge function with its own checks, keep only the anon key in the browser.
    Schema driftColumns added in the Supabase dashboard never became a migration; the repo's migration folder is months stale.Diff dashboard against repo, capture the true schema as versioned migrations, run migrations in deploy so environments stop diverging.
    Search engines see nothingLovable ships a client-rendered single-page app. The initial HTML is empty; crawlers and AI engines read the empty file.Server-render or pre-render the public routes. We did exactly this for our own site — a Lovable project now served as SSR on Cloudflare with full HTML for every crawler.
    Regeneration loopsEach fix prompt re-generates whole components; earlier fixes get overwritten.Move fixes into version control with review; use Lovable for new features, not for surgical edits it can't see.
    Storage buckets wide openBucket created public so uploads would display in the demo.Private buckets with signed URLs; policies on storage.objects; size and type limits on upload.
    Lovable Cloud vs your own SupabaseThe app runs on Lovable-managed infrastructure and nobody knows how to move it or who owns the data.Migrate to a Supabase project in your organisation, move auth users and storage, re-point the app, verify.

    How we work on a Lovable project

    1. Audit — two business days. We need the GitHub repo Lovable syncs to, read access to the Supabase project, and a login to the app. You get a written report: every open table, every misconfigured redirect, every exposed key, plus a fix-or-rebuild call and a fixed quote.
    2. Stabilise — first week. RLS, secrets, auth and storage fixed and tested. Your users' data stops being one prompt away from public.
    3. Complete — weeks two to four. Migrations reconciled, edge functions hardened, deploy pipeline to your domain, SEO-readable pages where they matter, and the features that never quite worked.
    4. Hand over — repo, Supabase project, domain and hosting in your name; a short runbook; and Lovable still connected so you can keep building on a foundation that no longer breaks.

    Fix or rebuild a Lovable app?

    Lovable-specific signals
    SignalFixRebuild
    Supabase schemaSensible tables with foreign keysEverything in one table, or five tables for one concept
    AuthSupabase Auth in use, needs configurationCustom auth invented in the client
    Edge functionsA few, each doing one jobBusiness logic split across client, functions and SQL with no pattern
    Component sprawlLarge but consistentThe same screen exists three times with different names
    Public contentNeeds SSR/pre-render for SEOFine as SPA if there's no public content — no rebuild needed

    In our experience most Lovable apps are worth fixing. The framework is mainstream, Supabase is solid, and the schema is usually recoverable. The audit says which, in writing.

    How long and how pricing works

    Audit in two business days. Most Lovable rescues are live on your own domain in two to four weeks. The audit is a fixed price; the rescue is a fixed quote agreed after it. No hourly meter, and you keep the report either way. Book a call and we'll tell you what a Lovable project of your shape usually needs before you spend anything.

    What we need from you

    • Access to the GitHub repository Lovable syncs to (or invite us to the Lovable project).
    • Read access to the Supabase project, or a note if it's on Lovable Cloud.
    • The live URL and a test login.
    • One paragraph: what it should do, what's broken, and your deadline.
