Do I need to know how to code?

No. You can build and deploy a working web application on Base44 entirely through natural-language prompts. Knowing a little about how the web works — what an API is, what a database row is — will help you write better prompts and debug faster, but it is not a hard requirement to ship your first project.

Do I own the generated code?

Yes. Base44 generates real, readable source code that you can inspect at any time and export from Project Settings. You are not locked into a proprietary runtime, so if you outgrow the platform you can continue development in any standard IDE without a rewrite.

Which LLM does Base44 use under the hood?

Base44 routes prompts through a frontier-class model — typically a Claude- or GPT-class model with strong coding performance. The exact provider is treated as an implementation detail and may change to keep quality high, which is why upstream provider outages sometimes show up as slow or failed generations even when everything else is fine.

Can I use my own backend or database?

Yes. The default setup uses Base44's managed backend primitives, but you can call external APIs, connect to your own Postgres, or integrate a third-party service like Stripe or Supabase from inside the generated code. Base44 does not force you to use its own database if you already have one.

How is Base44 different from Lovable, Replit, or Bolt?

All four turn prompts into apps, but they make different architectural bets. Base44 and Lovable run generation server-side with managed hosting. Replit gives you a full Linux container and a browser IDE. Bolt runs the whole toolchain in the browser via WebContainers. Pick based on where you want the runtime to live.

Is Base44 suitable for production apps?

For standard web applications — dashboards, internal tools, MVPs, content sites, small SaaS products — yes. For workloads with extreme scale, strict compliance requirements, or highly custom infrastructure, you'll eventually want to export the code and host it yourself. Many teams use Base44 for the first release and migrate later if the app takes off.

What happens if the platform goes down?

Your deployed app runs on Base44's edge hosting, so a builder-side incident does not immediately take your live app offline. Generation itself does depend on Base44's servers and the upstream LLM provider, so during an incident you may not be able to iterate until things recover. Live status is tracked at status.base44.com and mirrored here.

What is Base44? The AI-first app builder, in plain English

Q: Where does the app run?

By default your app runs on Base44-managed hosting at a Base44 subdomain. You can attach a custom domain any time by adding the DNS records Base44 shows you and TLS is provisioned automatically once verification succeeds. The hosting is served from an edge network so latency is reasonable worldwide.

What Base44 actually is

Base44 is an AI-first app-building platform. You describe an application in natural language and Base44 generates a complete full-stack web app — the front-end React code, the backend routes, the database schema, and a deployment target — that you can then iterate on inside the same in-browser builder. The core product sits in a fast-growing category the industry now calls 'vibe coding', alongside tools like Lovable, Replit Agent, and Bolt. Where a traditional IDE assumes you already know how to structure a project, Base44 assumes you know what the finished product should feel like and works backwards from that intent. The result is that non-engineers can ship a working, hosted application in an afternoon, and engineers can skip the boilerplate they'd otherwise write by hand.

The generation loop

Every prompt you send runs through a frontier-class large language model — typically a Claude- or GPT-class model with strong coding benchmarks. The LLM reads the current project state, plans a set of file-level changes, and then writes or edits real source code that lands in your project tree. You can inspect every file the model touches. Unlike closed no-code tools, Base44's output is not an opaque runtime configuration; it is an ordinary React + backend codebase. That matters for two reasons. First, when the app misbehaves you can read the code to figure out why instead of guessing at a black box. Second, if you outgrow the platform you can export the source and continue development somewhere else. The generation loop also captures a diff for every change, so rolling back a bad prompt is a single click rather than a manual undo.

Runtime and hosting

Deployed apps run on Base44-managed hosting by default. When you hit Publish, Base44 builds the app, uploads the artifact to its edge, and hands you a subdomain URL you can share immediately. You can attach a custom domain from Project Settings — you add the DNS records Base44 shows you and TLS is provisioned automatically once verification succeeds. Because the platform owns the runtime it can also inject managed backend primitives (auth, storage, a Postgres-compatible database) without you wiring them up. This is the biggest architectural difference from a browser-only tool like Bolt, which runs the entire dev environment inside WebContainers, and from IDE-first tools like Replit that give you a Linux VM to configure yourself.

Who Base44 is for

There are two clear audiences. The first is founders, operators, and product managers who can describe an application clearly but don't want to touch a terminal — Base44 lets them ship internal tools, landing pages, and MVPs without hiring a developer for the first iteration. The second is developers who want to skip the boring parts. Standing up auth, a database, a basic CRUD UI, and a deploy pipeline used to take a week; on Base44 it takes an hour, and the developer's time goes into the parts that actually differentiate the product. Both groups benefit from the same feedback loop: type a change, see it live, share the URL.

Where Base44 fits in the vibe-coding landscape

The category is crowded but the products are surprisingly different once you look past the marketing. Lovable leans hardest into a Supabase-first backend and production-grade output. Replit combines its long-standing browser IDE with an agent that operates inside a real Linux container. Bolt is unique in running the entire toolchain client-side via WebContainers. Base44's bet is that the fastest path from idea to live URL is an opinionated managed stack plus a great generation loop — you trade some flexibility for radically less setup. If your app is a standard CRUD tool, dashboard, or content site, that trade almost always pays off.

What Base44 is not

It is worth being honest about the edges. Base44 is not a replacement for a native mobile SDK; you get web apps that work well on mobile browsers, not iOS or Android binaries. It is not a low-code visual drag-and-drop tool — the primary interface is language, not a canvas. And it is not a substitute for engineering judgement on hard problems: if you need to design a novel algorithm, model a complex domain, or ship at very large scale, the LLM can accelerate a competent engineer but will not replace one. Treating Base44 as 'a really fast pair programmer for standard web apps' sets expectations correctly.

Getting started

Sign in at base44.com, hit New Project, and describe the app in one paragraph. Prefer concrete nouns and verbs — 'A dashboard for tracking freelance invoices with a client list, an invoice list, and a mark-as-paid button' beats 'a nice invoicing tool'. Publish immediately even if the app is rough, share the subdomain URL with a friend, and iterate from real feedback. That's the whole loop — the rest is practice.
