Frequently asked questions
What is Supacode?+
Supacode is an AI web and app builder. You describe what you want in plain English or Japanese, and it generates a production-ready website or app — HTML, CSS & JavaScript or React — that you can edit live and publish in one click.
Do I need to know how to code?+
No. Just describe your idea and Supacode builds it. You can refine anything with the AI assistant, and there is a full code editor if you want to go deeper.
Is it free to start?+
Yes. You can start building for free — no credit card required. Paid plans add more credits and features.
Can I use my own backend?+
Yes. Connect your own Supabase project and the AI builds against your real database, auth, and data — all owned by you.
Is my published site SEO-friendly?+
Yes. Published sites are prerendered for search engines and served from a global edge network for fast loading.
What can I build with it?+
Landing pages, portfolios, dashboards, SaaS front-ends, blogs, restaurant sites, and full React apps — anything from a simple page to a multi-page site.
