What is an AI app builder?

An AI app builder is a platform where you describe what you want in natural language and an AI agent writes the underlying code. Quality varies wildly. Some builders produce only sandboxed mockups; VibeKit produces real hosted apps with real GitHub repos and live URLs. The output is yours, the code is yours, and you can keep iterating after the first 'build'.

How is VibeKit different from Bolt, Lovable, v0?

Three structural differences. First: hosting is included in the same product, not as an upsell or external dependency. Second: every app gets its own persistent AI agent with full context of that app's code, history, and state — you can come back days later and continue where you left off. Third: native iOS app — most competitors are web-only. See /vs-bolt and /vs-lovable for full breakdowns.

Can I export my app or take the code with me?

Yes. Every app's code lives in a GitHub repo you control. You can clone it, fork it, run it locally, deploy it elsewhere — VibeKit doesn't lock you into a proprietary export format. If you ever want to leave, the code goes with you with zero friction.

What kind of apps can it build?

Anything Node.js-based: Next.js, Express, NestJS, Fastify, Astro, static sites. Common cases: landing pages, dashboards, CRUD apps, internal tools, lightweight APIs. Python / Go / Rust runtimes are on the roadmap. Mobile-native (iOS/Android) app generation is not on the roadmap — VibeKit builds web apps.

Is the AI app builder free?

Yes, the free tier hosts 1 app indefinitely with 256 MB RAM and 1.5 GB workspace. The free Qwen AI provider has zero cost. BYOK with Claude or OpenAI adds zero markup. Paid plans start at $19/mo for 3 apps and a custom domain.

AI App Builder — Real Apps, Not Mockups

Most "AI app builders" hand you a sandboxed mockup that lives in their cloud and dies when you stop paying. VibeKit hands you a real Next.js / Express / static app with a real GitHub repo, a real Fargate container, and a real URL. You own the code. The agent keeps iterating with you.

What makes a good AI app builder

Real output, not screenshots. The agent produces an actually-running app at a public URL — not a "preview" you have to leave the platform to deploy.
You own the code. GitHub repo from day one, exportable, forkable. No proprietary export format.
Persistent context. Come back a week later and the agent remembers your app's state, history, what's been tried, what failed. Most builders forget everything between sessions.
No artificial limits on shape. The agent's not picking from a template library — it can write any Node app you can describe.
Honest pricing. Free tier with hosting included. No "premium AI" tax that scales with how much you use it (BYOK fixes that).

The category honestly

Builder	Real deploys	Mobile client	Free tier	Best for
VibeKit	Yes (Fargate)	iOS + Telegram	1 app indefinitely	Mobile-first, full-stack Node, BYOK
Bolt	Yes (StackBlitz WebContainers)	Web only	Limited tokens	Browser-based prototyping
Lovable	Yes (via Vercel)	Web only	Limited builds	SaaS prototypes
v0 (Vercel)	Component preview	Web only	Free with limits	UI components
Replit	Yes (own infra)	Shallow viewer	Time-boxed	Python, multiplayer

Pick the one whose tradeoffs match your workflow. We think mobile + full ownership + BYOK is undervalued in this category — see vs Bolt, vs Lovable, vs Replit for the side-by-side.

How a build session goes

Pick a starting point. Template ("Landing page", "Dashboard", "CRUD API") or connect a GitHub repo.
Describe what you want. "Build a one-page site for my dog-walking business. Pricing, photos, contact form."
Watch the agent ship. Edits files, commits, triggers rebuild. You see live progress in the chat.
Iterate from chat. "Make the CTA purple", "Add a testimonials section", "Deploy to my custom domain". Each prompt is a real diff in the repo.
You're done. App is live at yourname.vibekit.bot or your custom domain. Code is in your GitHub.

What it can't do (yet)

Two honest caveats. (1) Node.js only — Python, Go, Rust are on the roadmap. (2) Web apps only — it doesn't generate native iOS or Android apps. If those are your use cases, this isn't the right tool. Everything else inside Node.js territory is fair game.
