Platform Overviews
Builder.io
Builder.io is a visual headless CMS and experience management platform that lets marketing and product teams visually edit content on any website or app built with any frontend framework — React, Vue, Angular, Next.js, or even native mobile apps. Unlike traditional CMSes, Builder.io uses a visual drag-and-drop editor that overlays directly on the live site, letting non-developers make layout changes without touching code. It's used by enterprise teams at companies like Microsoft, Snap, and Everlane for landing pages and experiment-driven content. Sites using Builder.io load scripts from cdn.builder.io and include builder-component, builder-block, and builder-content-id attributes throughout the DOM markup — these are the primary detection fingerprints. The Builder.io query API is accessed from builder.io/api/v1/ endpoints. Pricing starts at a free tier, with Growth plans from $10/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.
