I need a web-based landing-page maker my new and existing clients can log into and build pages on their own. The system must feel like a modern SaaS: drag-and-drop editing, live preview, and one-click publishing. Core requirements • Multiple ready-to-edit templates: Product Launch, Webinar Registration, Service Promotion • Fully responsive layouts, editable inside the builder (text, images, colours, fonts, forms, videos) • User accounts with roles: admin (manage templates, view analytics) and client (page creation, limits) • Publish options: (a) direct to our sub-domain through AWS S3 / CloudFront or similar, (b) downloadable HTML/CSS/JS zip • Basic page analytics (views, conversions) and easy pixel/integration slots for Mailchimp, HubSpot, etc. • Clean, documented code—React or Vue on the front end is preferred, but I’m open to your stack suggestion; REST or GraphQL API for future SaaS integration • Unit/integration tests plus a deployment guide Acceptance criteria 1. A new user can sign up, pick “Product Launch,” change content, and publish a mobile-friendly page in under 5 minutes. 2. Published pages score 90+ on Google Lighthouse (mobile performance). 3. My internal dev can add a new template following your documentation in <30 minutes. Let me know the editor library/framework you propose, show a related project you’ve built, and outline a realistic timeline along with anything you’ll need from me to get started. This landing page maker editor will be integrated into our existing and updating our existing page maker system. We want something eaxctly like the site found at pagemaker.io
