Vibe Code
AI app builder and AI website builder — describe it, watch it get built
Say what you want built — an app or a website. A frontier model writes the code live, next to a preview that runs, and the Web target deploys straight to a real URL.
How the AI app builder works
Describe what you want, pick a model and a stack, and watch the code get written beside a preview that runs.
- 9target stacks, from HTML to SwiftUI
- 13AI model versions to build with
- 5stacks that deploy to your own Vercel
- 6build briefs, matched to what you describe
- Describe itSay what you want. A game gets a game brief, a dashboard gets a dashboard brief.
- Pick a model and a stackChoose the AI that writes it and the framework, or let Vibe Code pick the stack from your wording.
- Watch it writeCode streams into a live card as a progress rail moves from Plan to Preview. Stop it any time.
- Open the StudioWeb and Game builds open in a live preview you can click and edit; other stacks get a matching preview or code panel.
Up to 20 builds every 5 minutes per account.
Nine target stacks, each with a preview that fits
Every stack gets the closest thing to a live preview, a real download, and a clear answer on deploy.
| Target | Live preview | Download | One-click deploy |
|---|---|---|---|
| Web — HTML/CSS/JS | In-app preview | Single .html file | Yes |
| Game — HTML5 canvas | In-app preview | Playable .html file | Yes |
| React 18 | StackBlitz | Vite project zip | Yes |
| Vue 3 | StackBlitz | Vite project zip | Yes |
| Next.js 15 App Router | StackBlitz | TypeScript project zip | Yes |
| iOS — SwiftUI | Code panel | .swift source file | No |
| Flutter — Dart | DartPad | .dart source file | No |
| React Native | Expo Snack phone simulator | App.js source file | No |
| Python | Code panel | .py script | No |
In detail
Previews and safety
- Generated code runs sandboxed: it cannot read this page's storage or make authenticated requests as you.
- React Native previews upload to Expo Snack, so Vibe Code asks for consent first.
- If a preview embed is unreachable, a read-only code panel takes over.
Thirteen AI model versions, solo or as a coding team
Choose which AI writes your code, down to the version — one model in Solo mode, or a different model in every CoWork role.
| Family | Versions you can build with |
|---|---|
| Claude | Sonnet 5.5, Opus 5.5, Fable 5.1 |
| GPT | GPT-6 Luna, GPT-6.1 Sol, GPT-6 Astra |
| Gemini | 3.5 Flash, 3.1 Pro |
| Grok | 4.5 |
| DeepSeek | V4 Pro |
| Qwen | 3.7 Max |
| Kimi | K3 |
| GLM | 5.2 |
Or build with a CoWork team
- Parallel BuildThree builders code the same brief at once. An Architect merges the best of each and explains it in a live report.
- The CouncilA Builder ships, a Challenger argues over two or three rounds, a Judge rules, and the Builder applies the verdict.
- PipelineDraft, Refine, Polish. Each model improves the file it is handed instead of starting over.
In detail
Casting and team details
- DeepSeek V4 Pro, Qwen 3.7 Max, Kimi K3 and GLM 5.2 are Vibe Code exclusives, not offered in plain chat.
- Pick a model per role, down to the variant; the picker shows each team’s flow before you commit.
- Parallel Build runs 4 model steps, the Council 7 to 10, Pipeline 3.
- If the merge or verdict step returns nothing, you are told it was not applied.
- All thirteen versions can also power Agent mode.
The visual Studio — edit the running app, not the file
Web and Game builds open over a live preview: click anything, change it or drag it, and the code updates alongside.
- Click to change anythingContent, Style and Layout tabs cover text, links, colours, fonts, spacing, sizing and alignment.
- Drag, then undoMove elements by dragging, or long-press on touch. Undo and redo reach back 60 steps.
- Describe one changeSelect an element and say what should change. Only that element is rewritten and swapped in.
- Refine by chattingAsk for dark mode or a confetti animation, and the whole page comes back rewritten.
- Phone-ready in one tapRewrites the page with proper phone breakpoints while keeping the desktop layout intact.
- Fill images and videoClick an empty slot to generate an image or video with AI, or upload your own.
In detail
Views and games
- Code, Split or Preview views; Desktop, Tablet and Phone frames, the last two scaled rather than true viewports.
- Game builds get Play mode with the keyboard routed to the game, plus Restart.
- Studio work autosaves, and downloads contain only your code.
Edit limits
- Element edits: 1,000-character instructions, 40 per 5 minutes. Refine: 2,000 characters, 10 per 5 minutes.
- Phone-ready: pages up to 180,000 characters, 4 per 5 minutes, size-checked before you pay.
- Uploads up to 8 MB (images) or 25 MB (video), with a warning if one would overflow browser storage. Video fills ask consent first.
The visual editor works on Web and Game builds. Other stacks change through Rebuild.
Set your brand once, and every build follows it
Tell Vibe Code what you are making, how it should look and what it needs once, in the My Style drawer.
- 16project types, from restaurants to games
- 87sub-types, each with its own layout
- 7style presets, plus 4 game art styles
- 35market locales with local currency and payments
- Your logo, your coloursUpload a logo and get six colour schemes drawn from its palette, beside 12 curated ones.
- Features before the buildBooking, reviews, contact forms, maps, galleries and more, tuned to your type of business.
- Prices from a photoPhotograph a menu or rate card to get items and prices, up to 40. A non-price-list photo returns nothing.
- A design system per projectSet colours, fonts, shape, buttons and motion by hand, from a written vision, or from JSON or Figma tokens.
In detail
Everything in the drawer
- Style presets: Minimal, Hyper-modern, Playful, Premium, Warm, Bold, Classic. Five copy tones, three motion levels.
- Locales set currency, dial code and local payment rails such as UPI, Pix and M-Pesa.
- Logos: PNG or JPG up to 5 MB, SVG up to 50 KB.
- Settings are defaults, so your own request always wins. An untouched drawer adds nothing.
- On Web and Game builds, colour and theme changes update the running preview instantly and carry into deploy.
The photo reader and generating a design from a written vision are paid; the rest of the drawer is free.
Download it, share a link, or deploy to your own Vercel
Every build leaves as real code — a download, an unlisted link, or a live site on hosting you own.
- Download a real projectReact, Vue and Next.js arrive as runnable zips; other stacks as single files.
- Share an unlisted linkA page on synergyai.studio that anyone with the link can open. Links unfurl in iMessage, Slack and WhatsApp.
- Deploy to your own VercelOne click pushes the code to your GitHub repo and ships it with a real URL.
- Catch problems before you deployA preflight scan flags leaked keys, local addresses, insecure links, placeholder text and missing titles.
- Connect your own SupabaseSave your Supabase project URL and public key once, and they fill in across previews, downloads and deploys.
- Ask the deploy GuideGet steps for hosting, domains, SSL and environment variables for all nine stacks. Up to 20 messages an hour.
In detail
Deploy and publish details
- Deployable stacks: Web, Game, React, Vue and Next.js. Deploys are spaced at least 30 seconds apart.
- Environment variables, deploy history with Redeploy, and an optional auto-deploy toggle.
- Your Vercel token is stored encrypted with AES-256-GCM.
- Only Web and Game publish as running pages, up to 5 MB; other stacks publish a code listing.
- Publishing copies embedded generated assets to public storage. Every publish is moderated.
- Supabase wiring covers Web, Game, React, Vue and Next.js; framework previews keep placeholders until deployed.
What the preflight checks
- Leaked API keys and private keys, including Supabase service-role keys; the anon public key passes.
- Localhost addresses, insecure http:// resources, broken anchors and placeholder text like lorem ipsum.
- Missing alt text, doctype, title or viewport meta. Hard failures need your confirmation to ship.
Keep, import and hand off every build
Everything you build stays a project you can reopen, copy, save as a folder, or push back to the repo it came from.
- Reopen any buildRename, duplicate or delete any build. Its style, design tokens and deploy settings travel with it.
- Import from GitHubBrowse your repos, open an entry file, edit it with AI and push back to the branch it came from.
- Save to your FilesWrite a project into your Workspace as a real folder, and open any Files folder back in Vibe Code.
- Hand it to an agentThe Builder agent takes over with tools, skills and memory, on the model you choose.
- Build in privacy modeForget & Burn is a server-enforced privacy mode. It gates autosave, design-token saves and paid actions.
- Get a guided first buildFive steps for a first session: set a limit, build, refine, connect Vercel, ship.
In detail
Projects and imports in detail
- Imports bring up to six companion CSS or JS files of 200 KB each as editable tabs. Imported JS runs only on the deployed site.
- Deleting a project revokes its published link.
- Agent mode gets your open project and style settings, and pauses at your spending limit with a Resume offer.
- Projects live in your browser, with a best-effort account copy. Another account signing in there purges the stored projects, drafts, held builds and brand data.
Pricing you control, before and during every build
You set the ceiling for each build, see what element edits and refinements cost before applying them, and can stop any time.
- Set the ceiling firstOne spending limit covers a whole build, split across a team’s steps. Your balance is always the hard stop.
- See the price before you pressElement edits and refinements show their price, and image or video fills an estimate, before you apply them.
- Stop means stopStopping a build halts the request, so output billing ends at what was already written; input context is charged up front.
- Broken edits are refundedAn element edit or Phone-ready pass that comes back broken is refunded automatically.
- Held builds wait for youHit your spending limit, a length ceiling or run out of balance, and the partial code is kept for Continue Build.
- Downloads cost nothingExports are packaged in your browser. Uploads, My Style settings and the deploy Guide are free as well.
One account covers every studio — top up as you go, or choose a monthly Pro or Studio plan.
Frequently asked questions
What is vibe coding, and what does Vibe Code actually do?
Vibe coding means describing software in plain words and letting an AI model write it. In Vibe Code you type the idea, pick a model and a stack, and watch the code stream in. Web and Game builds open in a visual Studio, and every stack downloads as real code.
Can the AI app builder make a real React, Vue or Next.js project, or only a web page?
Both. Vibe Code targets nine stacks, including React 18, Vue 3, Next.js 15, SwiftUI, Flutter, React Native and Python. React, Vue and Next.js download as runnable project zips with package.json and a src tree; SwiftUI, Flutter, React Native and Python as source files for your own project.
Which AI models can write my code?
Thirteen versions across eight families: Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi and GLM. Use one model alone, or cast a different model into each role of a CoWork team. DeepSeek V4 Pro, Qwen 3.7 Max, Kimi K3 and GLM 5.2 are not offered in plain chat.
What does it cost to build an app?
It depends on the model and how much it reads and writes: context is charged up front, output as it streams. A spending limit caps a whole build; your balance is the hard stop. Element edits and refinements show their price first, image fills an estimate. Downloads and the deploy Guide are free.
What happens if a build hits a limit part-way?
If a build hits your spending limit or a length ceiling, or your balance runs out, the partial code is saved and Continue Build offers to resume where it stopped once you top up. It only resumes into its own project, priced on the model it started with.
Can I deploy the app to my own hosting?
Yes. Connect your own GitHub and Vercel accounts, and one click pushes the code to your repo and ships it with a real URL. Web, Game, React, Vue and Next.js deploy this way, with environment variables, deploy history and optional auto-deploy.
Can I edit the generated site without writing code?
On Web and Game builds, yes. Click any element in the live preview to change its content, style or layout, drag it, and undo up to 60 steps. Or describe a change, chat to refine the page, or make it phone-ready in one tap.
Can I import an existing GitHub repository and edit it with AI?
Yes. Your repos appear in My Projects. Open one, edit its entry file with AI, and push the result back to the branch it came from. Up to six companion CSS or JS files come along as editable tabs.
