What Base44 does, who is behind it, what you can build with it, what it costs, and how to try it for free

Last updated Sep. 2026 | By DoitWithAi

Quick answer

Base44 is an AI app builder. You describe the app you want in plain English, and Base44 builds a working web app for you, including the database, user logins and hosting, with no coding. It was founded in 2025 by Maor Shlomo, was acquired by Wix the same year, and more than 10 million people have built on it. You can start free, and paid plans start from $16 a month billed annually ($20 month to month).

People searching "Base44" or "base 44" usually want a straight answer: what is it, is it for me, and what does it cost? This page answers all three in plain language, then points you to our deeper guides on each question.

What does Base44 do?

Base44 turns a written description into a working app. You type something like "a booking system for my cleaning business where clients pick a time slot and get a confirmation email", and Base44 generates the screens, the database behind them, user accounts and the logic that connects it all. You then refine it by chatting: ask for a new field, a different layout or an extra page, and it edits the app for you.

Built-in backend: data storage, user authentication and permissions are included, so there is no separate database or server to set up
Hosting included: apps are published on the web with a shareable link, and paid plans can connect your own domain
Integrations: connect apps to email, payments and other services
You own the code: on plans that include it, GitHub sync exports your full source code

Base44 App Builder vs Superagent

Base44 has two products that are easy to confuse. The App Builder is the core product: it builds custom apps and business tools like CRMs, booking systems, client portals and order trackers. Superagent, launched in 2026, is an autonomous AI agent that works in the background on tasks such as replying to messages, following up with leads or joining meetings, without you prompting it each time. Most people start with the App Builder.

Who is behind Base44?

Base44 was started in early 2025 by Israeli developer Maor Shlomo as a solo project. It grew quickly and was acquired by Wix, the publicly traded website builder, later in 2025. It now operates as part of Wix and passed 10 million users in August 2026. For more on ownership, security and what users complain about, read Is Base44 legit?.
