Platform Overviews
Bubble
Bubble is the most mature and powerful no-code application builder, enabling non-developers to create complex web applications with databases, business logic, user authentication, and API integrations through a visual editor. Unlike newer AI builders, Bubble uses a structured visual workflow editor rather than natural language generation — giving experienced users more precise control over application behavior. It powers marketplaces, social networks, CRMs, SaaS tools, and two-sided platforms that would typically require a development team. Bubble sites are hosted on bubble.io infrastructure and are identifiable through their distinctive JavaScript runtime, bubble.io CDN asset requests, and Bubble-specific URL patterns. Pricing starts at a free plan with Bubble branding, and paid plans start at $29/month.
WeWeb
WeWeb is a no-code frontend builder that connects to any backend, database, or API — enabling teams to build internal tools, client portals, dashboards, and web apps with a visual drag-and-drop interface backed by real data. Unlike no-code platforms that include their own database, WeWeb is deliberately frontend-only — it integrates with Supabase, Xano, Airtable, REST APIs, and GraphQL backends, giving developers control over the data layer while non-developers build the UI. It's popular with agencies building client-facing applications and operations teams automating internal workflows. WeWeb-published sites load all assets from cdn.weweb.io and use WeWeb-specific data-weweb-uid attributes throughout the DOM for component identification. The WeWeb runtime script is loaded on every published page. Pricing starts at $49/month for the Agency plan.
