What Is Base44? A Plain-English Guide for 2026

Base44 is an AI app builder that turns a written description into a working web app. You type what you want, for example "a booking app for my salon with customer logins and a calendar," and Base44 builds the screens, the database, the user accounts and the hosting for you.

I run Virtual Horizons, a Base44 Legend Partner. We build client portals, CRMs, voice AI agents and mobile apps on Base44 every week, and we have more than 10 apps live on the App Store and Google Play. This guide is the explanation I give clients on our first call, minus the sales part.

Who makes Base44?

Base44 was built by Israeli developer Maor Shlomo and bought by Wix in June 2025. According to TechCrunch, Wix paid $80 million in cash when the company was about six months old, bootstrapped, and had around 250,000 users.

Being owned by Wix matters for buyers. It means the platform has a large, public company behind it, which lowers the risk that your app disappears because a startup ran out of money.

How does Base44 work?

You chat with an AI builder, and it writes and runs the app for you. Each message asks for a change, and Base44 updates the app while you watch in a live preview.

Under the hood, a Base44 app is a real web app. It has:

• A frontend, the screens and buttons your users see, built with modern web code.
• A database, which Base44 calls entities. A "Customer" or "Booking" entity is like a smart spreadsheet tab your app reads and writes.
• User accounts, with sign up, log in and roles such as admin and regular user.
• Hosting, so you can publish to a live link in one click, then connect your own domain on paid plans.
• Integrations, like sending email, uploading files or calling AI models, plus backend functions on higher plans for custom server logic.

The workflow feels a lot like texting a developer who replies in seconds. You say "add a dashboard that shows this week's bookings," it builds it, you look, and you ask for the next change.

What can you build with Base44?

Most business software that runs in a browser is a good fit. In our own work, the projects that go best on Base44 are the ones where the value is in your process, not in pushing the edge of what software can do.

• Client portals where customers log in, see their project status, upload files and pay.
• CRMs and internal tools that fit how your team actually works, instead of bending to a generic product. See our CRM and automation work.
• Booking and scheduling apps for service businesses.
• MVPs for founders who need something real in front of users quickly.
• Mobile apps: Base44 can package your web app for the App Store and Google Play. More on that below and in our mobile apps service.
• AI features, like a chat assistant inside your app or a voice agent that writes call notes into your database. See Voice AI.

Can Base44 make mobile apps?

Yes. Base44 wraps your published web app in a native shell and generates the files the stores need: an IPA for Apple and an AAB for Google Play. You still upload and submit them yourself.

Base44's own App Store guide says downloading those store files requires the Builder plan or higher, and that "You are responsible for setting up and paying for your Apple and Google developer accounts." Apple charges 99 USD a year and Google charges a one-time US$25 registration fee.

A nice side effect: because the mobile app loads your live web app, most design and content changes show up in the app without sending a new version through store review. We wrote a full walkthrough in How to publish a Base44 app to the App Store. We also build App Native, a product that handles that wrapping and submission for Base44 apps.

Base44 vs. coding from scratch

Base44 is usually faster and cheaper to start, and custom code gives you full control. The right answer depends on how unusual your app is and how much you will change it.

This is not an all-or-nothing choice. A lot of our client projects start on Base44, prove the idea with real users, and only bring in custom code where it is actually needed.

Base44 vs. Lovable, Bolt and Bubble

They all build apps from prompts or visual editors, but they make different trade-offs. Base44 bundles the most backend for you. Lovable and Bolt lean more on you connecting outside services. Bubble is an older visual builder where you drag and drop rather than chat.

A side-by-side review on HostAdvice sums up the core trade-off well: Base44 is an "All-in-one solution: hosting, authentication, storage, and logic included," while its main drawback is vendor lock-in. We agree with that framing. The convenience is real, and so is the dependency.

Is Base44 part of a bigger shift?

Yes. Building software with AI and no-code tools has gone mainstream for business apps.

What has changed since that prediction is the AI part. Instead of learning a visual editor, you describe what you want. That makes the first 80% of an app very fast. The last 20%, the integrations, edge cases, security rules and app store polish, is where experience still matters.

How much does Base44 cost?

There is a free plan to try it, and paid plans start around $20 a month, with custom domains and app store files on the Builder plan and up. Credits limit how many AI requests you can make each month. We broke down every plan and the hidden costs, like developer accounts and domains, in our Base44 pricing guide.

Should you build it yourself or hire help?

Build it yourself if the app is simple and you enjoy tinkering. Bring in help when the app touches money, customer data, outside systems like your CRM or phone line, or the app stores.

That's the work we do as a Base44 partner: taking a prototype to production, wiring it into tools like GoHighLevel, adding voice agents, and getting it approved on both app stores. If you're weighing it up, our Base44 developers page explains how we work.
