The best Base44 alternatives, and when you don't need one

The short version

Which alternative fits depends on one thing: whether you already have a live app on Base44.

• Starting a new app? You’re choosing a builder. Lovable, Replit, Bolt, v0 and Emergent all build an app from a description, and each brings its own backend and hosting. For an owner, the useful difference is what you can take with you later: the code, the database and your users’ accounts. The table below sets that out for each one.
• Already running an app on Base44? No builder takes over a live Base44 app with its records and users. Switching builders means rebuilding. So the real choice is between rebuilding somewhere else and keeping the same app on accounts you own.
• Happy on Base44, just cautious? You may not need an alternative at all. Keep regular exports and stay.

The alternatives at a glance

From each company’s own pages, as of October 2026. Prices are the lowest paid plan billed monthly unless noted. Plans and credit rules change often, so check before you commit.

Builder by builder

Lovable

Lovable builds web apps from chat and hosts them. Its built-in backend, Lovable Cloud, uses Supabase’s open-source foundation: a Postgres database, sign-in, storage, functions and AI. New Lovable apps created from 13 May 2026 use TanStack Start; older ones are React and Vite.

Lovable documents its exit in detail. Its ownership guide says the code is yours, Git sync works on every plan, and the built-in backend can move to a managed or self-hosted Supabase project. The database export includes your users with their password hashes, so they keep their passwords after a restore. App connectors and AI features run through Lovable and need replacing when you move. Two limits: the Lovable editor itself can’t be self-hosted, and Lovable can’t import an existing GitHub repository; you can only export from it.

Pricing, as of October 2026: a Free plan with 5 build credits a day (up to 30 a month), and Pro from $25 a month for 100 credits. Lovable’s pricing page says hosting a small app is usually covered by the monthly Cloud grant. For a side-by-side, see Base44 vs Lovable.

Replit

Replit is a cloud development environment with an AI agent that builds full-stack apps. It provides a managed PostgreSQL database, file storage backed by Google Cloud Storage, and two sign-in options: Replit Auth, where your users sign in with a Replit account, or Clerk, which gives your app its own user accounts. Published apps run on Replit’s infrastructure, hosted in the United States.

Code leaves through the Git pane or a ZIP download. Replit also has an importer that accepts a Base44 project exported to GitHub. Its own guide says the import brings the code, assets, backend logic and table structure, but not database records or secrets.

Pricing, as of October 2026: a free Starter plan with one published app (the link goes down after 30 days), Core at $20 a month ($18 billed yearly) and Pro at $100 a month.

Bolt

Bolt builds in the browser and comes with Bolt Cloud: hosting, domains, a database with sign-in, file storage and server functions, which Bolt says are powered by Netlify and Supabase. On Pro or Teams you can use your own Supabase project instead, or claim an existing Bolt database into your Supabase organisation.

Bolt’s GitHub integration works in both directions: you can create a repository from a Bolt project, or open an existing repository as a new project.

Pricing, as of October 2026: Free with 1 million tokens a month (300,000 a day), Pro from $25 a month and Teams at $30 per member a month. Free hosting stops serving a site once it reaches its monthly traffic cap.

v0

v0 is Vercel’s AI builder. It writes Next.js apps and publishes them on Vercel. Databases come from providers in the Vercel Marketplace, such as Neon, Supabase and Upstash, each set up as an account with that provider. v0 connects to existing GitHub repositories, works on a separate branch for each chat and opens pull requests, and its FAQ says you can export the code and deploy elsewhere.

Pricing, as of October 2026: Free, then Plus at $30 per user a month and Business at $100. The $20 Premium plan is being retired and isn’t open to new users.

Emergent

Emergent builds web and mobile apps from chat on a React, FastAPI (Python) and MongoDB stack, and hosts them with a managed MongoDB database. Keeping an app deployed costs 50 credits a month. “Save to GitHub” pushes the project to a repository and branch you choose; the pricing page lists the GitHub integration from the Standard plan.

Pricing, as of October 2026: Free with 10 credits a month, Standard at $20 a month ($17 billed yearly) with 100 credits, and Pro at $200 a month.

Coding agents: Claude Code, Cursor and Codex

Some people searching for an alternative don’t want another builder. Coding agents such as Claude Code and Cursor read and edit a codebase wherever it lives, and host nothing. The code, the hosting and the data stay with you, and the agent is a tool you can swap. Base44 now lets these agents edit a Base44 app directly while the app keeps running on Base44; using Claude Code or Cursor with Base44 explains what each setup changes.

Free and open-source options

• Base44’s own Free plan includes 25 message credits and 100 integration credits a month and up to 5 apps, as of October 2026. Code export isn’t part of it.
• Dyad is a local, open-source app builder for Mac and Windows. You bring your own AI API keys. Its code is Apache 2.0, apart from a “pro” folder under a fair-source licence.
• bolt.diy is the official open-source version of Bolt.new, MIT-licensed, which you run yourself with the AI provider you choose. Its README notes that the WebContainers API it relies on must be licensed for commercial production use.

Open-source builders are free to run, but you pay your AI provider, and they give you an editor rather than a hosted backend. You still decide where the database, sign-in and hosting live.

If you already have a live app: rebuild or keep

Every builder above has its own backend, and a Base44 app is written for Base44’s. Its pages read and write through the Base44 SDK, so in a new builder every data call, sign-in and function has to be rewritten for the new platform. Data comes out as CSV, one table at a time, and Base44’s documentation says app users can’t be exported, so after a rebuild everyone sets a new password.

That leaves three honest options:

What keeping the app looks like

Unbase44 is made by Codama and is independent of Base44 and Wix. It moves the app you already have onto accounts you own:

• Your app’s own React frontend and a Base44-compatible backend (Deno and TypeScript) go into your private GitHub repository, with documentation written for people and for coding agents.
• The app runs on your Railway account, with the app, a MongoDB database and a storage bucket in one place, or on any Linux server you can reach over SSH. Railway’s Hobby plan is $5 a month including $5 of usage, according to Railway’s pricing as of October 2026.
• Tables with their access rules, records, users, backend functions, automations, workflows, AI agents, connectors and uploaded files all move.
• Users keep their passwords. Each user’s first sign-in on the new app is checked against Base44 once, so keep the Base44 app published until your active users have signed in.
• The copy starts in test mode while your Base44 app keeps serving users. When you’re ready, a guided switch-over turns test mode off, points the domain and helps move webhooks.
• The analysis is free and shows what’s in your app and a one-time price before you connect any account or pay. Migrations are free during the beta; the regular price starts at $99 per app.

You can run the free analysis to see what your app contains. The full order of steps is in how to migrate off Base44.

When you don’t need an alternative

• A brand-new idea. A builder is a good place to try it. Pick one whose exit you understand, and keep the code in GitHub from the start.
• A site that is really a landing page. A website builder will serve it better than any app builder.
• An app that works and costs what you expect. Stay, and keep copies: GitHub sync for the code, CSV exports for the data, and a written list of your secrets and connectors. If cost is the worry, Base44 pricing and credits breaks it down.
