5 Best Free AI App Builder Websites
Build websites and web apps by describing them in plain English. Free plans of Lovable, Bolt, v0, Replit and the open-source Dyad compared.
Here is a list of best free AI app builder websites. These tools, often called “vibe coding” tools, let you describe an app in plain English and get a working website or web app back. You then keep chatting to change it: add a login page, change the colors, connect a database. When it looks right, you can publish it or export the code.
Every service below has a free plan, but free plans are small. Most give you a few prompts per day, which is enough to build a simple landing page or prototype, not a full product. Limits change often, so check each pricing page for the current numbers.
Top Pick:
Bolt has one of the more usable free allowances and lets you keep projects private. If you want no limits at all and have your own AI API key, the open-source desktop app Dyad is free to use as much as your key allows.
Comparison Table:
| Website | Free allowance | Publish on free plan | Custom domain on free plan |
|---|---|---|---|
| Lovable | 5 credits per day (up to 30 per month) | ✓ | x |
| Bolt | 300K tokens per day, 1M per month | ✓ (with Bolt branding) | x |
| v0 | $5 of credits per month, 7 messages per day | ✓ (to Vercel) | — |
| Replit | Limited daily Agent usage | ✓ (1 app) | x |
| Dyad | Unlimited (uses your own API key or local models) | Export code | Your own hosting |
Lovable
Lovable builds full-stack web apps from a chat prompt, with a live preview next to the conversation. Its free plan includes 5 build credits per day, up to 30 per month, plus a monthly grant of Lovable Cloud credits for the backend (database, authentication and storage). One message typically uses one credit, so you get a handful of changes per day.
Lovable is known for producing good-looking interfaces with little prompting, and it can sync your project to GitHub.
| Pros | Cons |
|---|---|
| Polished designs out of the box | Only 5 credits a day |
| Built-in backend with Lovable Cloud | Free apps show a Lovable badge |
| GitHub sync |
Bolt
Bolt (bolt.new) from StackBlitz runs a full development environment in your browser. The free plan gives 300K tokens per day and 1M tokens per month, website hosting, and both public and private projects. Sites published on the free plan carry Bolt branding, and custom domains need a paid plan.
Because usage is measured in tokens, small edits cost less than big rewrites. Keeping prompts focused makes the free allowance last longer.
| Pros | Cons |
|---|---|
| Private projects on the free plan | Bolt branding on free sites |
| Free hosting included | No custom domain on the free plan |
| Full code editor in the browser | Large projects use tokens quickly |
v0
v0 by Vercel started as a UI generator for React and Tailwind components and has grown into a full app builder. The free plan includes $5 of credits per month with a limit of 7 messages per day, visual editing through Design Mode, GitHub sync and deployment to Vercel.
v0 is a good choice if you already use Next.js or Vercel, because the generated code follows those conventions.
| Pros | Cons |
|---|---|
| Clean React/Next.js code | Only 7 messages per day |
| Design Mode for visual edits | Tied to the Vercel ecosystem |
| One-click deploy to Vercel |
Replit
Replit is an online coding platform with an AI Agent that can plan, write and run an app for you. It supports many languages, not just JavaScript, and includes hosting and databases. The free Starter plan includes limited daily Agent usage and lets you publish one app.
Replit is the most flexible option here if your app needs a backend in Python or another language.
| Pros | Cons |
|---|---|
| Supports many programming languages | Free Agent usage is limited |
| Hosting and databases built in | Only one published app on the free plan |
| Full IDE when you want to edit code yourself |
Dyad
Dyad is a free, open-source AI app builder that runs on your own computer (Windows and macOS). It works like the cloud builders above, with chat on one side and a live preview on the other, but you bring your own AI: an API key from Anthropic, OpenAI, Google or others, or a local model through Ollama.
There is no sign-up and no daily limit from Dyad itself. Your only cost is whatever your AI provider charges, which can be zero with free API tiers or local models. The generated code is a standard project you fully own.
| Pros | Cons |
|---|---|
| Free and open source | You need your own API key or a local model |
| No daily limits from the app | Desktop app, not a website |
| Works offline with local models | You handle hosting yourself |
Final Thoughts:
Free AI app builders are best for prototypes, landing pages and small personal tools. Try Lovable or Bolt for the smoothest experience, v0 if you live in the Vercel world, and Dyad if you want to avoid daily limits entirely. For anything you plan to maintain, export the code to GitHub so you are not locked into one platform.
