Step-by-step tutorial on building a functional SaaS on mobile using VoxCode: setting up project scaffolding, speaking precise voice prompts, validating in the live Sandpack preview, and deploying to a public edge URL.
01.Step 1: Create Your Project on Mobile
Open your mobile browser and navigate to voxcode.app. Log in with your GitHub or Google account, or sign up with email to claim your 20 free credits.
Tap 'New Project' and select the Next.js starter template. Within 3 seconds, your mobile Virtual File System initializes with an active live preview.
02.Step 2: Spoken Voice Grammar Patterns
The secret to fast voice coding is using our three-part formula: Intent, Structure, and Action.
For example, instead of saying 'Make a website,' say: 'In app/page.tsx, build a landing page for an AI podcast summarizer. Include a hero section with an email waitlist input, three feature benefit cards, and a warm cream theme.'
Voice Tip
You can tap the 3D Voice Orb and speak naturally. If you make a mistake, simply say 'Undo that' or state your revision directly.

</main>
);
}03.Step 3: Real-Time Preview & Touch Testing
As the code is generated, the live Sandpack preview updates instantly in the adjacent tab. You can interact with buttons, scroll through components, and test touch targets just like your real end users will.
04.Step 4: Configuring Environment Keys
Need to connect Supabase, Stripe, or an AI provider? Swipe open the project settings drawer, add your `.env` variables securely, and save. Keys are encrypted client-side and injected into your sandbox execution.
05.Step 5: 1-Click Launch to *.voxcode.space
Tap the 'Deploy' rocket icon at the top of your screen. VoxCode creates a live edge deployment with an HTTPS subdomain (e.g., `podcast-briefs.voxcode.space`). Share the link with friends, customers, or on social media immediately!
