Build Apps with AI
Bring your ideas to life by chatting with AI
From idea to a live site, no code required
You describe it, the AI builds it as real web pages. Click anything to tweak it, then put it online in one click.
- Free to use
- No coding needed
- Real HTML, CSS & JavaScript
- Multi-page websites and apps
- One-click deploy
- Runs entirely in the browser
How it works
Describe it, or pick a template
Type a sentence about what you want, attach a screenshot if you have one, or start from a template and skip the blank page.
Make it yours
Chat for bigger changes, click on the page for small ones. The theme panel changes colors and fonts across every page at once.
Deploy and share
Pick a name and your app goes live on its own oneapp.dev link. It's free, and you can push updates whenever you like.
Prompt to app
Describe it and watch it get built
Start with a sentence like “a portfolio with a projects page” and the AI writes the pages while you watch. You get a proper site where every page links to the others. Attach a picture when you want it to match something you've seen, or just ask a question in the chat when you want advice.
- Multi-page websites with real links between pages
- Attach reference images to show what you mean
- Keep going with follow-up prompts
Visual editing
Click on the page to change it
Small changes shouldn't need a prompt. Click any part of the page and change its text, size, spacing, colors or image right there. The theme panel changes colors and fonts across the whole app in one go. And when you do prompt, you can select an element first so the AI only touches that spot.
- Click-to-edit changes that show up instantly
- One theme panel controls colors and fonts everywhere
- Select an element and prompt changes for just that spot
Pages & preview
Every page, side by side
The pages board lays your whole site out as live previews, so you spot the odd page out before a visitor does. Open any page and check it at phone, tablet and desktop sizes, or go fullscreen for the real thing.
- A live board of every page in the app
- Phone, tablet and desktop previews
- Fullscreen preview for the real feel
Real code
It's real code, and it's yours
Behind the preview is plain HTML, CSS and JavaScript, formatted so you can actually read it. Open the code view to browse the files, edit them by hand or copy anything out. There's no build step and nothing locking you in. Each page works as a normal web page anywhere.
- Plain HTML, CSS and JavaScript, neatly formatted
- Edit the source directly in the built-in editor
- Version history lets you roll back a bad change
Publish
Online in one click
When it looks right, hit Deploy and pick a name. Your app goes live at your-name.oneapp.dev on a free link you can share anywhere. Keep it public, or make it unlisted on a paid plan when it's only meant for a few people. Deploy again whenever you make changes.
- A free yourname.oneapp.dev link
- Public or unlisted visibility
- Redeploy in seconds after changes
…and plenty more
The smaller things that make building here feel easy.
Templates for a head start
Start from a working site: portfolios, stores, blogs, landing pages, even small apps like quizzes and habit trackers.
Your choice of AI model
Pick the model that writes your code. Free models are included, and paid plans add premium options like Claude and the bigger GPT models.
Bring your brand
Set a brand name, color and palette before the first prompt so everything comes out matching from the start.
Reference images
Attach screenshots or photos with a prompt and the AI uses them as direction for the design.
Version history
Every generation is snapshotted. If a change goes sideways, restore an earlier version in one click.
Apps that do things
Your apps can have working parts: carts, filters, countdowns, and games that save progress in the browser.
Nothing to install
Building, editing, previewing and deploying all happen in the browser. Open the page and start.
All your apps in one place
Every app you've built lives on your Vibe Coding home, ready to reopen, search or delete.
Who uses Vibe Coding
Anyone with an idea and a browser.
Founders testing an idea
Put up a landing page or waitlist this afternoon and see if anyone bites, before writing real code.
Small businesses
A site for the restaurant, salon or studio, with a menu or services page in your own brand colors.
Creators
A link-in-bio page or portfolio that actually looks like you.
Students and first-time builders
Watch prompts become HTML, then open the code view and learn from something you actually made.
Events and communities
A page for the meetup, wedding or launch, with a countdown, ready in time to share the link.
Little tools for yourself
Habit trackers, flashcards or a quiz for friends: small apps that save their data in the browser.
Works with the rest of OneCompiler
Vibe Coding is one part of OneCompiler. When you want to work on the code directly, the editor and studio are a click away.
Frequently asked questions
What is vibe coding?
Vibe coding means building software by describing what you want in plain language and letting an AI write the code. You steer with prompts and feedback instead of writing the code yourself. OneCompiler's Vibe Coding brings that to the browser: you describe a website or app, the AI builds it as real web pages, and you shape it by chatting or by clicking on the page.
Do I need to know how to code?
No. Prompts and click-to-edit cover the whole flow from idea to a live site. Knowing a little HTML or CSS helps if you want to fine-tune by hand, and the code view is right there whenever you're curious.
What kind of apps can I build?
Multi-page websites and browser apps: landing pages, portfolios, stores, blogs, event pages, and interactive things like quizzes, to-do lists and trackers. Anything that needs its own server or database, like user accounts, isn't a fit yet. Apps keep their data in the visitor's browser instead.
What do I actually get?
A set of real HTML, CSS and JavaScript files, formatted so they're easy to read. Each page is a normal web page on its own. There's no framework or build step, so the result works anywhere.
Is Vibe Coding free?
Yes. Building, editing and deploying are free, with a daily limit on AI generations. Paid plans raise that limit and unlock premium AI models and unlisted deploys.
How does deploying work?
Click Deploy and pick a name; your app goes live at that-name.oneapp.dev. Public deploys are open to anyone with the link, and paid plans can make a deploy unlisted. Deploy again whenever you've made changes.
Which AI models can I use?
There's a model picker on every prompt. Free accounts choose between several free models, and paid plans add premium ones like Claude and the larger GPT options.
Can I make it match my brand?
Yes. Set a brand name, primary color and palette when you create the app, attach reference images so the AI can see the direction, and adjust the theme's colors and fonts anytime after.
What if a change ruins the design?
Every generation is saved as a version. Open the history and restore any earlier version in one click.
Can I edit the code myself?
Yes. Switch to the code view for a file tree and editor. Changes you make by hand are saved and show up in the preview like any other edit.
How is this different from the OneCompiler editor?
The editor is for writing code yourself, in 100+ languages. Vibe Coding starts from a description and writes the code for you. Plenty of people use both: sketch an app here, then keep building on the code wherever they like.
