Describe an app. Watch it build itself.
vMira Build turns a prompt into a working web app — running live in your browser, then deployed to Vercel with one more prompt. The runtime is warm by the time you finish typing.
Prompt to app
From a sentence to a site.
Describe it, and Mira writes the code, runs it live, and deploys it — no setup, no cold start.

The build loop
From prompt to live URL.
Four steps, one conversation — a warm sandbox, a live preview, assets on demand, and a one-line deploy.
01 — Persistent sandbox
Your sandbox stays warm.
Each project keeps its own dev server running and node_modules installed. Close the tab, come back tomorrow, and pick up exactly where you left off — no reinstall, no cold start.
02 — Live preview
Watch the code stream in.
Mira writes components and serves a live preview URL that updates as the code streams in. Full Node.js, every npm package, real files — the page is interactive the moment it renders.
03 — In-chat assets
Make the assets as you build.
Need a hero image, an intro video, a theme song? Generate them in the same conversation and drop them straight into the project — no stock sites, no second tool. Included in your plan.

Dropped straight into the project — no stock sites, no second tool.
04 — Ship it
Deploy is a sentence.
“Deploy this to Vercel” returns a live URL in seconds. One click exports the full source tree to a fresh GitHub repo as a clean PR. You own what Mira built — no lock-in.

How it compares
Bundled beats standalone.
Where the in-chat, one-plan model wins — and where focused single-purpose builders still have an edge.

Questions
Frequently asked questions.
What is vMira Build?
An AI app builder inside vMira chat. You prompt; it generates code; a persistent per-project sandbox runs the dev server and serves a live preview URL; you deploy to Vercel with one more prompt.
Is it free?
Yes — vMira Build is included with every vMira plan, starting free. Builds draw from the same plan budget that powers chat, image, video, and music; heavier use is covered by a higher plan (Go, Plus, or Max). No per-task or per-build fees.
How is it different from Lovable, Bolt.new, or v0?
Persistent per-project sandbox (your node_modules and dev server stay warm between sessions), native asset generation (image/video/song) inside the same conversation, a real Bash shell on the sandbox, and bundled with the rest of vMira on one plan. See the comparison pages for side-by-side tables.
Can I export the source code?
Yes — every project has an Export button (full source-tree zip) plus a one-click 'export as PR' to a new GitHub repo. You own what Mira built. No lock-in.
What about deploying?
Connect Vercel; one prompt deploys to a live URL. Cloudflare Pages and Netlify are on the Q3 2026 roadmap.
Does it support backend code?
Yes — the sandbox is a real Node.js environment, so you can use any npm package, write Express/Hono/Next.js routes, hit databases, etc. A Bash pane gives you direct shell access alongside the chat.
