Build Real Apps by Chatting
Greta.sh is an AI full-stack app builder from Questera. Describe what you want in plain language and it writes the React frontend, the backend logic, the Supabase database and the integrations — then deploys it. An AI developer and project manager rolled into one: you steer with prompts, it does the engineering.
The point is that you end up with a real product, not a throwaway mockup. Production code, a live backend, synced to your GitHub, on your own domain — you keep the code and the data.
What You Get
Prompt-to-code across the whole stack. A real Supabase backend with auth and user accounts. Full code ownership with automatic GitHub sync. Stripe checkout, subscriptions and billing. 50+ drop-in growth components — onboarding, chatbots, analytics, email. Chat and visual editing, so you refine by prompt or hand-tune in the editor. Live preview while you build, and one-click deploy to a custom domain.
What's in the Guide
The six-step workflow from first prompt to deployed app, three worked prompt-to-output examples — a SaaS analytics dashboard, a launch page with a Supabase-backed waitlist, and a client portal with per-client data isolation — and the pro tip that matters most: feed big builds in sections rather than one giant prompt.
