2. Nobley

Most no-code builders treat APIs as an afterthought. Nobley doesn't.Import an OpenAPI spec or GraphQL schema and your client's backend becomes a fully typed, queryable data source in under 60 seconds — no manual wiring, no custom connectors. Then bind that live data directly to components, visually.On top of that, you get real app primitives: state management, event handlers, conditional rendering, and formulas. So you're building actual interactive web apps, not glorified landing pages.An AI agent helps you scaffold and build pages faster, so you spend less time on boilerplate and more time on the work that matters.And the pricing is built for how agencies actually work: €24/mo covers 5 client sites compared to Webflow's $14–23 per single site.Nobley is the only visual builder that combines serious API integration, real interactivity, AI assistance, and agency-friendly pricing in one product.
