Base44 vs Lovable (and Replit, Bolt): what you can take with you

The short version

Base44 and Lovable both build a full-stack web app from a conversation and host it for you. The differences that matter to an owner, as of October 2026:

• The backend. Base44 runs your app on its own backend, with a NoSQL database reached through the Base44 SDK. Lovable’s built-in backend, Lovable Cloud, is built on Supabase, so your data sits in Postgres.
• What you can take out. Lovable syncs your code to GitHub on every plan and exports the whole database, user accounts and password hashes included. Base44 syncs code on the Builder plan and up, exports records as CSV one table at a time, and says app users can’t be exported.
• Where the app can run. Lovable documents moving both the frontend and the backend to hosting you choose. A Base44 frontend can be hosted elsewhere, but it still talks to Base44’s backend.
• Price. Base44’s paid plans start at $20 a month ($16 billed yearly); Lovable Pro starts at $25 a month. Both meter AI use in credits, and the credits measure different things.

Neither is better for everyone. If you’re choosing for a new app and the exit matters to you, Lovable’s exit covers more of the app. If you already have users on Base44, read the last section before you switch.

Side by side

From each company’s own pages, as of October 2026.

How you build

The day-to-day experience is similar: describe, preview, publish. Base44’s pricing page lists AI building, a responsive visual editor and an integrated backend on every plan, with in-app code edits from Starter. Lovable offers its agent, visual edits and a code editor where you can read and change the source.

Both now reach beyond their own editor. Base44 lets you bring your own coding agent, such as Claude Code or Cursor, to an app’s code on the Builder plan and up. Lovable’s Git sync lets you work in your own IDE and push changes back. If that’s the part you care about, Base44 with Claude Code or Cursor goes into the details.

Backend and database

This is where the two differ most.

Base44 provides what its developer docs call a flexible NoSQL data layer, with built-in sign-in and access control, realtime updates, TypeScript backend functions and integrations for AI, email and files. Your pages reach all of it through the Base44 SDK, and Base44’s docs say integration calls always run on Base44 infrastructure. The live app’s AI and email actions draw on your plan’s integration credits. Base44’s backend and database, explained covers how the pieces fit.

Lovable describes Lovable Cloud as using Supabase’s open-source foundation: a Postgres database, sign-in, storage, realtime and functions, with an instance size you can increase as the app grows. You can also connect your own Supabase project instead. Hosting and backend usage draw on Lovable credits, with a monthly Cloud grant on Free, Pro and Business.

In practice, Lovable’s data is a Postgres database you can restore elsewhere, while Base44’s lives behind Base44’s API.

What you can export and own

Both companies say you own what you build. Base44’s pricing FAQ says you own your code, your data and your users. Lovable’s pricing FAQ says you own your code, your projects and the customer data stored in Lovable. Their documentation shows how each part actually comes out.

Code

• Base44: a ZIP from the Code tab, or two-way GitHub sync, both on the Builder plan or higher. With GitHub sync, table definitions are managed in Base44 and aren’t in the repository. Changes merged to main reach Base44, and you still click Publish. See exporting your code from Base44.
• Lovable: two-way Git sync on every plan, into a repository that is private by default, and a ZIP download on paid plans. Lovable can’t import an existing repository; you can only export from it.

Data

• Base44: export each table to CSV from the Data dashboard. Links between tables are IDs stored in fields, so keep them when you move.
• Lovable: export a table to CSV, or request a full database export from Advanced settings. It’s a Postgres backup with schema and data, and you can request one every 24 hours.

Users

• Base44: its privacy documentation says app users can’t be exported. Password hashes stay with Base44.
• Lovable: user accounts are in the database export with their password hashes, so users keep their passwords when you restore into a Supabase project. Sessions don’t carry over, and sign-in providers such as Google need setting up again.

Everything else

On both platforms, some features are services the platform runs for you, and they don’t travel as files. On Base44 that’s integrations, connectors, automations, workflows and AI agents. On Lovable, its migration guide lists app connectors and AI features as running through Lovable, needing a replacement when the backend moves. Secrets have to be set again in both cases.

Pricing models

As of October 2026. Credits on the two platforms measure different things, so compare what your app does in a month rather than credit counts.

Base44 sells plans with two monthly allowances: message credits for building with AI, and integration credits for what your live app does, such as sending email or calling AI. Starter costs $16 a month billed yearly ($20 month to month) with 100 message and 2,000 integration credits. Builder, which GitHub sync, the ZIP download and outside coding agents need, is $40 a month billed yearly with 250 message and 10,000 integration credits. Hosting is part of the plan. Base44 pricing and credits goes deeper.

Lovable uses one credit balance for building, for hosting and the built-in backend, and for AI features inside your app. Pro starts at $25 a month for 100 credits, plus 5 free build credits a day and monthly Cloud and AI grants. Lovable’s pricing page says the cost of hosting a small app is usually covered by the included grant; busier apps draw on the credit balance. Business starts at $50 a month.

Hosting and lock-in

Base44 hosts the app. Its developer docs say you can host a frontend elsewhere, but the app’s code is a client for Base44’s backend: every record, sign-in, function and integration call goes to Base44. Leaving means rewriting that data layer, or running a backend that answers the same calls.

Lovable hosts by default and documents three setups: everything on Lovable, a hybrid with your own hosting or Supabase, and fully self-managed. The Lovable editor itself can’t be self-hosted.

Replit and Bolt in the same comparison

People often compare all four. The same questions, as of October 2026:

Base44 vs Replit

Replit is a cloud development environment with an AI agent, closer to a programmer’s workspace than Base44’s editor. It gives your app a managed PostgreSQL database and file storage, and your users sign in either with Replit accounts or through Clerk. Replit can import a Base44 project from GitHub, but its guide says records and secrets aren’t imported.

Base44 vs Bolt

Bolt builds in the browser and includes Bolt Cloud: hosting, a database with sign-in, file storage and server functions, which Bolt says are powered by Netlify and Supabase. Its GitHub integration runs both ways and can open an existing repository. On Pro or Teams, a Bolt database can be claimed into your own Supabase organisation.

Is Base44 better than Lovable?

It depends on what you value.

• Base44 suits you if you want one place that builds, hosts and runs everything, including integrations, workflows and AI agents, and you’re comfortable with the backend staying on Base44.
• Lovable suits you if you want your data in Postgres and a documented route to move the app, users included, to your own Supabase and hosting later.

Whichever you pick, connect GitHub early and export your data on a schedule.

Already on one of them?

• From Base44 to Lovable. Lovable can’t import an existing repository, and its backend is Supabase, so a Base44 app has to be rebuilt there: new data model, new sign-in, rewritten functions, and a password reset for every user. Moving from Base44 to Lovable, Bolt or Replit covers it step by step.
• From Lovable to Base44. Base44’s “Migrate from another platform” imports Lovable and Bolt projects: the tables in the public schema with their data, keys and the frontend from GitHub.
• Keeping your Base44 app as it is. If the reason to switch is ownership rather than the editor, you don’t have to rebuild. Unbase44 moves the same app, with its records, users, functions, workflows and agents, into your own GitHub repository and onto your own Railway account or Linux server. Users keep their passwords: each one’s first sign-in on the new app is checked against Base44 once.
