About VULK — AI App Builder: Full-Stack Apps, 3D Websites & Flutter Apps
Overview
VULK is an AI app builder that turns a prompt, voice note, screenshot, or Figma design into a deployed full-stack application. It generates web apps with React and Next.js, Flutter and React Native mobile apps, and 3D websites built on Three.js, each paired with an auto-generated PostgreSQL backend, authentication, and REST API.
Founded by João Castro and Joana Matos and based in Vila do Conde, Portugal, VULK is a bootstrapped product with live, paying customers and data residency in the EU. It targets production shipping with one-click deployment and full source export.
Key Benefits
- Generate a complete full-stack app from a single prompt, including the database and authentication
- Export 100% owned source code with no proprietary runtime or kill switch
- Build across web, mobile, 3D, and Shopify platforms from one project
- Deploy online in about 90 seconds with one click
- Preview changes live in isolated Firecracker microVMs with sub-2s cold boot
- Publish Flutter apps to the Apple App Store and Google Play
How It Works
Describe your idea as a prompt, voice note, screenshot, or Figma file. VULK's multi-agent pipeline routes planning, generation, repair, and validation to the model best suited for each step, producing the frontend, backend, and database together. Preview the result live, then deploy to a hosting provider or export the full source.
Use Cases
- Indie founders turn an idea into a working web app or online store
- Agencies ship client prototypes and production apps using volume credits
- Mobile developers generate Flutter apps and publish them to app stores
- E-commerce teams build Shopify themes, apps, and Hydrogen storefronts
- Designers and studios create immersive Three.js 3D websites and scenes
- Prototypers convert prompts into interactive product demos and dashboards
Why Choose This Product
VULK differentiates by generating the entire application stack rather than stopping at the frontend. Every project runs without a proprietary runtime, so exported code stays fully owned and portable to any hosting provider or repository.

Frequently asked questions about VULK — AI App Builder: Full-Stack Apps, 3D Websites & Flutter Apps
Is VULK paid?
Yes, VULK is paid-only. Plans start at Builder €19.99/mo and go up through Pro, Team, Max, and Business, each unlocking the coding models in the plan, backend (PostgreSQL), source export, custom domains, and production shipping. There is no free plan.
Do I own the code?
Yes. Every project exports as a clean repository with no proprietary runtime, no built-with badge, and no kill switch. You can push it to your own GitHub, host it anywhere, and license it however you want.
Can I cancel and keep my apps running?
Yes. Once a project is exported or deployed to your own Cloudflare or Vercel, it has zero runtime dependency on VULK. Your apps keep running even if VULK disappeared.
What languages and frameworks does VULK generate?
Web: React + Vite and Next.js 16. Mobile: Flutter (iOS, Android, and web) and React Native + Expo. 3D: Three.js. E-commerce: Shopify Liquid, App, and Hydrogen. Backend: PostgreSQL with REST endpoints and Prisma.
What AI models does VULK use?
Generation routes per phase: a fast classifier, a heavy planner in the Claude Opus or Gemini Pro class, a generation model tuned for the surface, and a repair model that reads compile errors. Available models include GPT-6 Astra, Claude Fable 5.1, and Gemini 3.8 Flash.
Do you offer refunds?
No. All purchases are final and VULK does not provide refunds, but you can cancel anytime to stop future renewals. Your access continues until the end of the current billing period.
