Every AI app builder in one table: Lovable, Base44, Bolt, v0, Replit, Cursor, Windsurf, Antigravity, Claude Code and Codex

Ten AI app builders in one table: where the code lives, who hosts it, whether a database and login come built in, how usage is metered, and which are free.

What is Google Antigravity, and can someone who can't code use it?

Antigravity is Google's free agent-first builder. What it is, what it leaves out, where the only real download is, and how it compares to Claude Code.

Bolt vs Lovable for people who don't code

Both build an app from a prompt and host it free. Bolt adds mobile apps and meters in tokens. Lovable keeps a GitHub copy on every plan. How to choose.

Cursor for people who can't code: what it is, what it costs in shape, and Cursor vs Claude Code

Cursor is a code editor with an AI agent inside. What that means if you have never opened an editor, what the free plan gives, and Cursor vs Claude Code.

How do I add login to an app I built with AI, without touching code?

Where the login switch lives in Lovable, Base44, Bolt and Claude Code, and why a login screen alone does not make your app private.

Why does my AI app builder keep burning credits on the same bug?

Every fix is a fresh guess with the same missing facts, and you pay per guess. What a fix costs on each builder, why the bug returns, when to stop.

Your AI-built app is not working: blank screen, not updating after publish, or stuck on 'thinking'

Six reasons a Lovable or Base44 app stops working: blank screen, preview fine but published stale, stuck on thinking, chat silent. What each means.

Why your app says 'done' but nothing changed

Your AI builder said done and nothing changed. Either you are looking at the wrong copy or the change was never made. Six causes and how to tell which.

Claude Code desktop app or the terminal: which one should a non-coder use?

Use the desktop app. Same builder, same login, but you see and approve each change on screen. What the terminal adds, and when it is worth it.

Codex for people who can't code: what it is, how to install it, and how it compares to Claude Code

Codex is OpenAI's AI builder, in every ChatGPT plan, free included. What it is, how to install it on Mac or Windows, and how it differs from Claude Code.

Claude Code for beginners who can't code: your first hour

Yes, you can use Claude Code with no coding experience. What the first hour looks like, what you won't understand yet, and the habits that get you an app.

Custom domain not working on Lovable or Base44: pending, connecting, or connected but not live

Pending, verifying, or live but showing nothing: what each state means, what the address book is doing behind it, and which part is yours to fix.

Do I need a database for my app?

If people save anything in your app and expect it back tomorrow, yes. How to tell in a minute, where your builder keeps it, and why data goes missing.

How to get your code out of Lovable or Base44 (and what you can actually take with you)

Lovable syncs code to GitHub on every plan. Base44 needs a paid plan for GitHub or a ZIP. The code comes out. Data, logins and the backend do not.

How to install Claude Code when you have never opened a terminal (Windows and Mac)

Claude Code installs as a normal app on Windows and Mac, no terminal needed. Plus the terminal route, the not recognized error and the API key trap.

Is Claude Code free? What it actually costs a non-coder

No. It comes with a paid Claude plan and has no free tier. Usage is metered by time, not credits. Plus the API key trap and the no-card way to try this.

Is Lovable safe? What the 2026 leaks mean for your app

Three public incidents since 2025, only one on Lovable's own servers. The rest came from apps with one rule left off. What is theirs and what is yours.

Is my Lovable app leaking data? A five-minute check with no code

Four checks in one browser tab, no code: a private window, a changed address, a page-source search and the red Unrestricted badge. What a failure means.

Lovable alternatives for people who can't code (including the one where you own the files)

Base44, Bolt, v0, Replit Agent, and Claude Code or Codex: what each gives you for one prompt, where each stops, and which one fits the wall you just hit.

What to do when Lovable can't finish your app

Lovable stalls on the last part of most apps for one of three reasons. How to tell which one you hit, what to try first, and when to take your code out.

Lovable vs Base44 for people who don't code: an honest comparison

Base44 keeps the whole app inside one platform and hides the plumbing. Lovable hands you the code and a backend you can take with you. How to choose.

Lovable vs Claude Code: when to switch and when not to

Lovable builds and hosts your app in the browser. Claude Code writes files you own on your computer. Switch when you hit a wall under the hood, not before.

What is an API key? Why your AI tool is asking for one

An API key is a password your app uses to reach a service such as an AI model. Billed by use, separate from a chat subscription, never safe inside a page.

What is Claude Code? A plain-English answer for people who don't code

Claude Code is Anthropic's AI builder. It works in the files on your computer, not a chat window. Not the Claude app, not a website builder, not hosting.
