If you want one place that builds the app, stores its data, handles logins and hosts it, and you never want to see the plumbing, Base44 is the simpler tool. If you want a builder that hands you the code and a backend you could take somewhere else later, Lovable is the better bet. Both are real products that build working apps from plain-language prompts. Both stop at the same kind of wall. The difference is what you are holding when you get there.
Who each one is for
Base44 is for the person who wants the whole thing in one box. You describe the app, and Base44 generates the screens, a database, user login, hosting and a live link, all inside its own platform. It also has built-in services your live app can use, such as sending an email, generating an image or calling an AI model, and those are metered from your plan rather than set up by you. Base44 was bought by Wix in 2025 and still runs as its own product.
Lovable is for the person who cares about the look of the thing and wants to own the code underneath it. Lovable generates a standard React app (React is a common way of building web pages, in files any web developer would recognize) and keeps a live two-way copy of that code on GitHub, the standard place code is stored online, on every plan. It also gives you a built-in backend called Lovable Cloud. A backend is the part of your app that runs on a server: the database, the logins, the file storage. Lovable Cloud is a Supabase project managed by Lovable, and Supabase is an open-source database and login service that you can also run under your own account. If you prefer, you can connect your own Supabase project instead.
What each one does well
Base44 is fast to a complete, live app. Logins, a database and hosting are on by default, so a booking form, a client portal, an internal tool for your team or a small marketplace prototype comes out working with fewer decisions on your side. You never leave the chat to wire up a separate service.
Lovable does the front end well, and it keeps you free from the first prompt. The app it generates is a standard project that can be hosted on any major cloud or on Lovable itself. Publishing to a lovable.app address costs no credits, and the site stays live with no expiry. A custom domain needs a paid plan. Because GitHub sync works on every plan, a copy of your code exists outside Lovable the whole time, and edits you push to GitHub flow back into Lovable.
Where each one stops
Both stop at the same wall. There is a specific change the builder cannot make, or an error it cannot explain, or a bug that comes back while the credit meter runs. Neither product is broken when that happens. A no-code ceiling looks exactly like this. What differs is how much of your app you can carry out with you.
With Base44, exporting the code (as a ZIP file or to GitHub) needs the Builder plan or higher. Below that, the code stays inside Base44. Even when you export, the code is written to talk to Base44’s backend: your data, your users’ accounts and the server-side logic all run on Base44’s service, and moving off it means someone rebuilds that half. Credits come in two kinds. Message credits pay for building. Integration credits pay for what the live app does, like sending an email or calling an AI model, unless you plug in your own API key for that service. Unused credits expire at the end of each cycle. When integration credits run out, those features fail and your users see a generic error. Once you connect GitHub, you also lose the ability to roll back to versions from before the connection.
With Lovable, one credit balance pays for three things: building, hosting the app with its Cloud backend, and any AI features inside the published app. Unused credits on a paid plan roll over while you keep subscribing. When the balance hits zero, the published pages keep serving, but AI features stop and apps that rely on Cloud can pause. So a live app with real users has a running cost you need to watch. The GitHub sync handles one branch at a time, and Lovable cannot import a repository you already have. On the free plan, help means the docs, the docs assistant and the community Discord. The support form comes with a paid plan, with a first reply within a day on weekdays.
Base44’s help looks similar: docs with an ask-a-question box, a Discord where the team and the community answer, and support tickets. Its support policy says plainly that it does not debug your individual app’s code, prompts or architecture. Lovable’s policy does not promise that either. In both, the person who fixes your app is you.
How to decide
Ask three questions.
- Do you expect to leave the builder one day? If yes, Lovable, because the code is on GitHub on any plan and the stack is standard. If the app is an internal tool or a prototype you will throw away, Base44 is fine.
- Will strangers pay to use this? Then where the data and the accounts live matters. Lovable lets you keep the backend under your own Supabase account. Base44 keeps it in Base44.
- How many decisions do you want? Base44 leaves fewer for you to make. Lovable gives you more knobs, and more responsibility for what happens when a knob is wrong.
| Base44 | Lovable | |
|---|---|---|
| What one prompt gives you | Screens, a database, logins, hosting, a live link | Screens as a standard React app, a Cloud backend, a live link |
| Where your code lives | Inside Base44; ZIP or GitHub export on the Builder plan and up | In Lovable, with a two-way copy on GitHub on every plan |
| Where your data and logins live | Base44’s managed backend | Lovable Cloud (a managed Supabase project), or your own Supabase |
| How usage is metered | Message credits to build, integration credits when the live app sends email or calls AI; unused credits expire | One credit balance for building, hosting and AI; unused paid credits roll over |
| When credits run out | Building stops; live features that need credits fail with a generic error | Pages keep serving; AI features stop and Cloud apps can pause |
| Where you get help | Docs, Discord, support tickets; no debugging of your own app | Docs and Discord on every plan; a support form on paid plans |
What switching actually involves
Moving from Base44 to Lovable is a rebuild, not an import. You describe the app again, with the old app open as your spec, and Lovable builds it fresh. Before you leave, download whatever your plan lets you take, code and data, while the account is still active. Moving from Lovable to Base44 works the same way in practice: describe it again. In both directions, the screens come back quickly. The part that takes time is the data and the accounts, because they were living in the old platform’s backend.
There is a third option, and it is the one this site exists for. Use Lovable’s GitHub copy as a starting point, and keep building it with a builder that runs on your own computer, such as Claude Code. That is the switch covered in the companion guide on Lovable versus Claude Code, and it is where you stop asking whether a builder allows something. The free first lesson, You’ve outgrown Lovable, is written for the moment you hit the ceiling on either tool, and it needs no card.
In the next ten minutes, open the builder you are using and find where your code and your data live on your current plan. Then write down the one change it will not make for you. If that change is about how something looks, stay. If it is about what happens under the hood, you have your answer.
