Question 1

What is VULK?

Accepted Answer

VULK is an AI app builder that turns prompts, voice, screenshots, video, Figma designs, or pasted URLs into production-ready full-stack applications. It outputs React + Next.js web apps, Flutter and React Native mobile apps with App Store and Google Play submission, Three.js / WebGL 3D websites and games, AI-generated video backgrounds, Shopify themes, and a multi-tenant PostgreSQL backend per project — with full source code ownership.

Question 2

Can VULK generate AI video backgrounds and 3D scenes for my site?

Accepted Answer

Yes. VULK routes across 25 video models including Google Veo 3.1, OpenAI Sora 2 Pro (via OpenRouter), Runway Gen-4 Turbo, Kling 2.5/3, MiniMax Hailuo 02, Alibaba Wan 2.7, Luma Ray 3, Pika 2.2, ByteDance Seedance 2, and xAI Grok Imagine. For 3D scenes it uses Three.js + React Three Fiber + WebGL with shaders, postprocessing, and Rapier physics, and can generate textured 3D models (.glb / .gltf) from text or images via Microsoft TRELLIS hosted on AWS SageMaker, fal AI, and Replicate.

Question 3

Can VULK build Flutter mobile apps and submit them to the App Store and Google Play?

Accepted Answer

Yes. VULK generates Flutter apps with Clean Architecture, Riverpod, go_router, native auth (Apple, Google, GitHub, Microsoft), push notifications (FCM + APNs), and RevenueCat IAP. Server-side build fleet (`vulk-appbuild`) produces signed `.apk` and `.ipa` artifacts; iOS submission via App Store Connect API and Android via Play Console API are automated.

Question 4

What AI models are available, and can I bring my own keys?

Accepted Answer

VULK ships 16+ models out of the box — Gemini 3.1 Pro (default), Gemini 3.1 Flash, Claude Opus 4.7, Claude Sonnet 4.6, GPT-5.4, Grok 4.20, DeepSeek, Llama, Mistral. Bring Your Own Model (BYOK) is supported for OpenAI, Anthropic, Google AI, Mistral, Groq, DeepSeek, Together AI, Fireworks, and self-hosted Ollama, with zero markup on those calls.

Question 5

How does the multi-tenant backend work?

Accepted Answer

Every project that needs a database gets a dedicated PostgreSQL instance on the `vulk-api-engine` (Bun + Hono). VULK auto-generates CRUD endpoints, JWT authentication, role-based access control, and Redis-backed rate limiting. Frontend and backend are wired together automatically. Currently 779+ projects run on the engine.

Question 6

Can I import an existing site, video, or Figma file as a starting point?

Accepted Answer

Yes. Paste a competitor URL and VULK clones the visible layout into editable code. Paste a YouTube link or screen recording to extract the UI flow. Drop a screenshot to reverse-engineer components. Connect Figma via OAuth or paste a public URL for design-to-code conversion. Voice input via Whisper transcription is also live.

Question 7

How does the MCP server work with Claude Desktop, Cursor, and Windsurf?

Accepted Answer

VULK publishes `vulk-mcp-server` on npm. Run `npx vulk-mcp-server` and add the connector to Claude Desktop, Cursor, Windsurf, VS Code, or any MCP-compatible client. From inside the AI client you can generate, edit, deploy, and inspect VULK projects without leaving your IDE.

Question 8

Do you charge if a generation fails?

Accepted Answer

No. VULK runs a 10-step quality validation pipeline (forbidden patterns, AST validation, real `tsc --noEmit` type-check, Stripe scaffolding correctness, accessibility, bundle size). If any gate fails before the project is persisted, you are not charged for that generation.

Question 9

How does the 7-day paid trial work?

Accepted Answer

Builder Trial is €1.99 for 7 days with the full 1,000 Builder credits; Pro Trial is €3.99 for 7 days with 2,500 Pro credits. After the trial the plan renews at the standard monthly price (€19.99 Builder, €39.99 Pro) unless cancelled before renewal. Higher plans — Team €79.99, Max €199, Business €299 — bill at standard pricing without an intro offer.

Question 10

Can I export my code and self-host it?

Accepted Answer

Yes. Generated code is fully owned by you with no VULK licensing. Export the entire project as a ZIP (source + config), or push directly to a new GitHub repo via OAuth. Custom domains are attached automatically via Cloudflare for SaaS with auto-TLS, but you can also deploy to Vercel, Netlify, Railway, or your own infrastructure.

Question 11

Is my data EU-resident and GDPR-compliant?

Accepted Answer

Yes. VULK stores data on AWS RDS Frankfurt + Hetzner Falkenstein/Helsinki + Hostinger Lithuania. Right-to-be-forgotten, data export, and breach-notification flows are live. The DPA register documents 22 sub-processors, all SOC 2 / ISO 27001 aligned (Stripe, AWS, Cloudflare, Sentry). Passwords are Argon2id-hashed; OAuth tokens and BYOK keys are encrypted at rest with AWS KMS envelope encryption.
