Why migrate to Lovable instead of staying on base44?

Lovable's two big wins over base44: real GitHub sync (not beta), and a Supabase-backed backend that you can read and edit directly. You also get a calmer pricing model and fewer reports of the regression-loop pattern that plagues base44. The trade-off is that Lovable is also AI-driven, so some of the same risks apply. If you want to escape AI platforms entirely, this is not your migration.

What's different about Lovable's backend compared to base44's?

Lovable uses Supabase as the backend by default. That means real Postgres you can SQL into, real auth, real storage, and real RLS — not a proprietary entity layer hidden behind an SDK. When you export from Lovable, the exported code points at your Supabase project, so the export actually runs anywhere Next.js runs. Base44's exported code is locked to the base44 SDK; Lovable's is portable from day one.

Will my base44 frontend code work inside Lovable?

The React + Tailwind portion ports cleanly because Lovable uses the same stack. Every component that calls @base44/sdk has to be rewritten against Supabase. Roughly the same forty-percent rewrite ratio as any migration. Lovable's AI agent can do most of the rewriting if you point it at one component at a time.

Can I export from Lovable and self-host later?

Yes. Lovable exports to GitHub with working production code that runs anywhere Next.js runs. The Supabase backend is also portable — you can take the schema, RLS, and functions and run them on your own Postgres. This is the strongest argument for moving to Lovable: you do not get re-locked-in. Base44 cannot say the same.

How does Lovable's pricing compare to base44?

Lovable starts at $20/mo Pro for individuals, $30/user/mo Teams. Base44 paid tiers run $50–$500/mo. Lovable bills by message credits but rolls them over, unlike base44. Most teams who migrate find their monthly platform cost drops by thirty to fifty percent, plus they get clearer credit consumption.

What about Lovable's reliability?

Better than base44, not perfect. Lovable has had its own outages but publishes a status page and incident reports. Production traffic on Lovable hosting is acceptable for most apps but enterprise teams typically export to Vercel for higher SLAs. The development environment is more stable than base44's editor; the editor-hangs-and-crashes class of problems are rare on Lovable.

Should I use Lovable's hosting or export to Vercel?

For development and prototyping, use Lovable's hosting. For production, evaluate. If you have under 1,000 active users, Lovable hosting is fine. If you have more or you need fine-grained edge configuration, export to Vercel. The export is one click and produces real Next.js code, so this is a low-cost decision to defer.

Migrate Base44 to Lovable: AI Full-Stack with Supabase Backend

Lovable is the most direct competitor to base44 in the AI-vibe-coding space. The migration is the simplest of any in this set because the mental model maps almost one-to-one. You are trading one prompt-to-app platform for another that does the same job with better fundamentals.

The killer feature for migrants: Lovable's exported code actually runs outside Lovable. Base44's does not. That alone makes Lovable a safer long-term bet, even if you stay on Lovable's hosting forever.

Why migrate to Lovable

Three reasons we see teams pick Lovable:

Same shape as base44, less broken. If you like AI-driven prompt-to-app development but you are tired of regression loops, credit burn, and editor crashes, Lovable solves most of those. The agent is more disciplined, the editor more stable.
Real Supabase backend. No more proprietary SDK layer. You get Postgres, auth, storage, and RLS exposed natively. You can connect to your Supabase project from any tool.
Working GitHub export. Lovable exports to a real Git repo with code that runs on Vercel, Netlify, or your own infra. Not beta. Not "you still need the SDK." Real, working, portable code.

The trade-off: it is still AI-driven, still subject to a vendor's pricing and decisions, and still abstracts some of the underlying complexity. If you want to leave AI platforms entirely, Next.js + Supabase is the right destination instead.

What you keep, what you rebuild

Layer	What you keep	What you rebuild
React components	85–95% (JSX, Tailwind, hooks)	SDK calls (`@base44/sdk` → Supabase)
Routing	URL structure	Re-implement on Lovable's framework conventions
Schema definitions	Field names + types	Recreate as Supabase tables (Lovable handles this via prompts)
Database rows	Data	None
Authentication	User identifiers	Supabase Auth (Lovable wires this for you)
RLS	Logic	Rewrite as Postgres policies
Backend functions	Function bodies	Wrap as Supabase Edge Functions or API routes
File uploads	Files	Re-upload to Supabase Storage
Webhooks	Endpoints	New URLs at Lovable hosting or Vercel
Scheduled jobs	None	Build with Supabase pg_cron or external
Real-time	None	Free with Supabase Realtime

The rewrite is mostly mechanical. The new code is portable.

Architecture: source vs target

Base44 (current):

[browser] → CSR React (base44 hosted)
              ↓
        @base44/sdk
              ↓
       base44 backend (managed, opaque)

Lovable + Supabase (target):

DEVELOPMENT:
[lovable.dev in browser] → Lovable editor + AI agent
                              ↓
                          your Next.js / Vite project
                              ↓
                        @supabase/supabase-js (real client)

PRODUCTION:
[user browser] → Lovable hosting OR Vercel/Netlify
                       ↓
                  Supabase (Postgres + Auth + Storage + Functions)

Same shape as base44 from the user's view. Wildly different from the developer's view: you can SSH into Supabase, run SQL, edit RLS, and inspect anything.

Step-by-step migration plan

Phase 1 — Discovery (Week 1)

1. Inventory base44 surface area

Standard inventory: entities, functions, integrations, scheduled tasks, webhooks. Grep your SDK calls.

grep -rn "base44\." src/ | tee migration/sdk-calls.txt

2. Decide on hosting target

Lovable hosts your app for free with a *.lovable.app URL, or with a custom domain on paid tiers. For higher-traffic apps, export to Vercel or Netlify and use Lovable purely as the development environment.

Hosting	Best for	Note
Lovable hosting	Apps with under 1,000 active users	Free SSL, custom domain on Pro
Vercel (export from Lovable)	Production-grade, edge, multi-region	Standard Next.js deploy
Netlify	Static-heavy or Jamstack	Standard Next.js deploy

We default to "develop on Lovable, deploy to Vercel" for production migrations.

Phase 2 — Lovable setup (Week 1)

3. Open Lovable and create the project

Visit lovable.dev. Sign in. Create a new project.

Lovable prompts you for an initial description. Paste a brief summary:

Migrating an app from base44. Project management for small teams.
Tables: users, projects, tasks, comments. Email + magic link auth.
Stripe billing. Slack webhook for notifications. Use Next.js 15
with Supabase backend. Connect to my existing Supabase project.

Lovable scaffolds: Next.js project, Supabase client, basic auth flow, starter UI.

4. Connect Supabase

Lovable creates a Supabase project for you on first prompt, or you can connect an existing one. Connection details land in your project's environment variables automatically.

NEXT_PUBLIC_SUPABASE_URL=https://xxxxx.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=...

Phase 3 — Rebuild iteratively (Weeks 1–3)

5. Drop in your base44 components

Upload src/components/ from your base44 export. Lovable's editor handles the file tree.

6. Prompt the agent feature-by-feature

Create a /projects route. Server component. Fetches projects from
Supabase where owner_id = auth.uid(). Renders the existing
ProjectList component. Use the existing Tailwind classes.

Verify. Snapshot. Move to the next feature. Same discipline as every AI-platform migration: do not let the agent rewrite the whole app at once.

7. Recreate schema and RLS in Supabase

Lovable's agent can write the SQL from a description, but verify before applying. The schema migration is identical to the Next.js + Supabase migration:

create table public.projects (
  id uuid primary key default gen_random_uuid(),
  owner_id uuid not null references auth.users(id) on delete cascade,
  name text not null,
  status text not null default 'draft',
  created_at timestamptz not null default now()
);

alter table public.projects enable row level security;

create policy "owner_can_select" on public.projects
  for select using (auth.uid() = owner_id);

8. Replace SDK calls

Mechanical work. Lovable's agent does most of it if you point it at one component at a time.

// before
const projects = await base44.entities.Project.find({ filter: { ownerId } });

// after
const supabase = createClient();
const { data: projects } = await supabase
  .from("projects")
  .select("*")
  .eq("owner_id", ownerId);

Phase 4 — Backend functions (Week 3)

9. Port backend functions

Each base44 function becomes either a Supabase Edge Function or a Next.js Route Handler. For functions that need to run inside the database transaction context (like RLS-aware operations), prefer Edge Functions. For external API integrations like Stripe webhooks, Route Handlers are simpler.

// app/api/create-invoice/route.ts
import { NextResponse } from "next/server";
import { createClient } from "@/lib/supabase/server";
import Stripe from "stripe";

export async function POST(req: Request) {
  const { project_id, amount } = await req.json();
  const supabase = createClient();
  const stripe = new Stripe(process.env.STRIPE_SECRET!);

  const invoice = await stripe.invoices.create({ customer: "...", auto_advance: true });
  await supabase.from("invoices").insert({ project_id, stripe_id: invoice.id, amount });

  return NextResponse.json({ id: invoice.id });
}

Phase 5 — Data backfill (Week 3–4)

10. Export from base44, import to Supabase

Standard backfill via @supabase/supabase-js and the service-role key. Run from Lovable's terminal or locally.

import { createClient } from "@supabase/supabase-js";
import projects from "./export/projects.json";

const sb = createClient(process.env.SUPABASE_URL!, process.env.SUPABASE_SERVICE_ROLE!);

for (const batch of chunk(projects, 500)) {
  await sb.from("projects").insert(batch.map(toRow));
}

Phase 6 — Deploy (Week 4)

11a. Deploy on Lovable hosting

Click Publish in Lovable. Add custom domain on Pro tier. SSL is automatic.

11b. Or deploy to Vercel

Export to GitHub via Lovable's export feature. Connect the repo to Vercel. Standard Next.js deploy:

# After exporting to GitHub, on your local machine
npm install -g vercel
vercel link
vercel env pull .env.local
vercel --prod

Add custom domain on Vercel. Done.

Phase 7 — Cutover (Week 4–5)

12. Dual-run + DNS swap

Standard cutover. Dual-write for one to two weeks. Validate parity. Swap DNS at low-traffic hour.

Phase 8 — Sunset

13. Decommission base44

Cancel after thirty days of stable Lovable + Supabase production.

Common pitfalls

1. Trusting the agent on RLS. Lovable's agent writes RLS policies that often miss edge cases. Always test policies with at least two distinct users before going to production.

2. Mixed-component prompts. "Add a logout button and clean up the dashboard" is the same kind of prompt that breaks base44's agent. Same discipline applies on Lovable: scope every prompt to one component or one route.

3. Forgetting to export early. Lovable's export feature is robust, but you should export and npm run build locally within the first week to confirm portability. If something is wrong with your build, find out early.

4. Supabase project sharing. Lovable creates a Supabase project under its own organization by default. For production, transfer ownership to your organization or use your own Supabase project from the start.

5. Pricing tier upgrades sneaking up. Lovable's free tier is generous but limited. If your migration is large, the message-credit usage will push you to Pro or Teams within the first week. Budget for it.

6. SEO regression on URL changes. Same warning as every migration. Map old URLs to new; ship 301s.

Timeline + team

Three to five weeks with this team:

One full-stack engineer. Owns the rebuild. Forty hours per week.
One product owner. Validates parity. Five hours per week.

Lovable's agent does enough mechanical work that one engineer can drive most migrations. Add a second person for apps with non-trivial RLS or compliance requirements.

Cost

Migration tiers:

Tier	Price	What you get
Small	$6,000	3–4 weeks, simple app, Lovable + Supabase
Medium	$12,000	4–6 weeks, custom integrations, complex auth
Enterprise	$25,000+	Compliance prep, white-glove cutover, on-call support

Lovable: $20/mo Pro or $30/user/mo Teams. Supabase: $0–$25/mo at small scale. Total ongoing: $20–$55/mo for most teams. If exporting to Vercel, add Vercel Pro at $20/user/mo.

Often cheaper than base44 on monthly cost, with a clearer credit model.

DIY vs hire decision

DIY this if:

You have shipped a Next.js + Supabase app before, or you are comfortable working with AI agents and reviewing their output.
Your app has under thirty entities and standard auth.
You can spare three to five weeks of focused time.

Hire help if:

You have not used Supabase before.
Your app has paying users and you cannot risk an agent-written bug.
Your team is base44-only.

This is the second-most-common DIY migration after Replit. Lovable's agent does enough heavy lifting that experienced full-stack devs can drive it solo.
