What will you build?
Describe it in plain words. The AI writes a real web app — with its own database, files and address — live in about a minute.
Say what the app should do, in any of 4 languages.
The AI writes the code and shows you a live preview.
One click puts it on your own URL — or your own domain.
Everything a real app needs, built in
Not a demo on someone else’s server — each app gets its own isolated stack.
Its own database
Every app gets a private SQL database, with a visual studio to browse, edit and query your data.
Sign-in for your users
Ask for accounts and the AI builds passwordless email login — no passwords to leak, ever.
Payments, email & APIs
Stripe checkout, transactional email, Telegram alerts — your keys stay in an encrypted vault.
AI security review
One click reviews your app for XSS, injection and leaked secrets before you publish.
Files & traffic
Private file storage with an upload manager, and a traffic chart for every app.
Your domain, your rules
Custom domains with automatic HTTPS, and public, password-protected or private access.
Also on vx-build: the open-model API gateway
One key, one OpenAI-compatible endpoint, 120+ open models at transparent prices.
curl https://vx-build.ai/v1/models \ -H "Authorization: Bearer vxb_your_key"
Use it with Claude Code
Point Claude Code, Claude Desktop or any Anthropic SDK at vx-build and build against open-weight models. One command:
curl -fsSL https://vx-build.ai/install.sh | sh
It checks your key and the endpoint before anything changes, prints the settings, and only touches your shell profile if you say yes. Rather read it first?
