How to Choose a Vibe Coding Tool That Fits What You're Building

Why every "Lovable vs Bolt vs Base44" list disagrees

Search for a comparison and you'll find one list calling a tool the easiest for beginners and the next calling the same tool one for developers. Both can be honest. They score different things (speed to a first version, price, how much control you get), and the tools change so often that a ranking is out of date within weeks. Many of those lists also carry affiliate links. So does this page, and the link is labelled where it appears.

The question "which tool is best?" has no answer until you add "for what". So this guide doesn't rank anything. It shows you how the tools differ in kind, which questions settle the choice, and how to check any tool yourself.

The three kinds of AI build tool

Almost every tool you'll see advertised is one of three kinds. The brand names change; the kinds don't.

A chat artifact is the fastest way to see an idea. You describe a calculator, a landing page or a quiz, and the chat app draws it next to the conversation. There's no project to set up. That speed comes from what it leaves out. Some artifacts can now save a little data between visits, but that store belongs to the artifact, not to an app with its own user accounts, and there's nowhere safe to hide a secret key.

An AI website builder is where most people start vibe coding. Lovable, Base44 and Bolt.new are examples. You describe the app, it writes the code, and when the app needs a database or a login page, the builder sets one up. Press publish and it's live at a web address. The trade is that the builder makes many decisions for you, and some of what it sets up may not come with you if you leave.

An AI coding agent works the way a developer does, on real files in a project folder. Claude Code and Codex are examples. Some now run in a desktop app or a browser tab, not only a terminal. An agent can change any project, including one a builder made for you. What it won't do on its own is give you somewhere to host the app or a database to store things in; you choose those, and the agent helps you connect them.

Four questions that decide it

1. Does anyone besides you need to use it? If it's a tool for yourself, a chat artifact may be all you need, even one that saves a few notes between visits. The moment other people need their own accounts, or the app has to keep real records (sign-ups, orders, customer details), you need a builder or an agent plus hosting.

2. Does it handle logins, money or personal data? All three need a backend, a part of the app that runs on a server where visitors can't see or change it. A builder sets that up for you. With an agent you set it up yourself, with the agent's help. Either way, this is the answer that rules a chat artifact out.

3. Can you leave, and what comes with you? Ask about three things separately: the code, the data and the user logins. Some builders let you sync your code to GitHub (a place that stores a copy of your project's files) and move your database to a standard provider. Others run the backend on their own system, so the code can leave but the database and logins need rebuilding somewhere else. Neither is wrong. It's a trade you should make on purpose, before your app has real users.

4. How much of the code do you want to see? If you never want to open a file, a builder fits. If you keep hitting changes that are hard to describe in a chat message but easy to point at in a file, or you want to understand what your app actually does, that's the point where a coding agent earns its place.

When to move up a kind

Starting small is sensible. Sketch an idea in a chat artifact, and when it needs to remember things, take payments or live at a web address, rebuild it in a builder. Stay in the builder for as long as describing what you want keeps working; automatic hosting and a ready-made database are a real advantage, not training wheels.

You don't have to switch everything at once, either. When one hard problem defeats your builder's AI, paste the failing code, the exact error and what you expected into a coding agent or a chat, get a fix, and bring it back to the builder. You get deeper reasoning on one problem without abandoning a project that works. If your builder syncs to GitHub, an agent can also work on the same project directly, with the changes flowing back.

What to look for on a pricing page

This page quotes no prices, because they change too often to stay accurate here. Read the provider's current pricing page instead, and look for these six things:

• What you're charged for. Credits, messages or usage. Find out how much one request uses, since a big change can use several.
• Whether failed attempts cost you. An AI stuck fixing and re-breaking the same thing still uses up credits. Our guide to getting out of a fix-and-break loop can save you more than any plan choice.
• What's billed separately. The database, hosting, a custom domain, sending email and AI features inside your own app can each have their own meter.
• What's locked to a higher plan. Code export or GitHub sync, a custom domain, private projects and removing the builder's branding are the usual ones. Check these against question 3.
• Which currency it bills in. Many bill in US dollars, so what you pay in rand moves with the exchange rate, plus your bank's foreign-transaction fee.
• Where your users' data is stored, and whether you can choose. Under POPIA that's your responsibility, not the tool's. Our guide to whether your AI builder's backend is POPIA compliant explains what to ask.

What no tool does for you

Every tool on the market will happily write code that runs. None of them decides what's safe for your app, and the advertising rarely says so. Whatever you pick, these stay your job:

• Keeping secret keys out of code that runs in the visitor's browser. Our guide to why an API key can't go in frontend code shows why.
• Confirming a payment really happened before you deliver anything. That's what a webhook is for.
• Deciding what personal data you collect, and telling people.
• Testing with real users before you call it finished. Our guide to why a vibe-coded app isn't production-ready by default covers the usual gaps.

A tool can help with every one of these if you ask. It won't do them unless you ask.

The prompt: have your AI check a tool for you

Run this in an AI chat that can search the web. If yours can't, paste in the tool's pricing page and its main documentation pages yourself. Fill in the brackets, and run it once per tool you're considering.

I'm not a coder. I want to build: [one sentence about your project].
Who will use it: [just me / customers / staff].
It needs to: [let people log in? store their data? take payments? send email?]
I'm considering: [tool name].

Using only this tool's own current documentation and pricing page
(not reviews or "best of" lists), answer these for my project:

1. Which kind of tool is it: a chat-based tool, an AI website builder
   that sets up hosting and a database for me, or a coding agent that
   works on files I host myself?
2. For my project, what would it set up for me, and what would I have
   to set up myself?
3. If I leave later, what comes with me: the code, the data, the user
   logins? How do I take each one?
4. How does it charge: what is the unit, what uses it up, do failed
   attempts count, and what is billed separately?
5. Where would my users' data be stored, and can I choose the region?
6. What can't it do for a project like mine?

Give the link to the page each answer came from. If you can't find
something in the tool's own docs, write "not found" instead of guessing.

What to check in the AI's answer

• Every answer has a link to the tool's own site. Open two of them and confirm they say what the AI claims. An answer with no link is a guess.
• "Not found" is a useful answer. If the docs don't say where your data is stored or how to leave, ask the tool's support before you build on it.
• Question 3 has three separate answers. If the reply only covers the code, ask again about the data and the logins.
• Anything described as "unlimited". Look for the fair-use limit in the same page's small print.

Run it for a second tool and put the two answers side by side. That comparison is about your project, and it's current the day you run it, which no ranked list can be.
