OnePageSiteBuilder is a self-service software tool for creating and publishing one-page websites. Users choose from 43 templates, preview them on desktop and mobile, and edit text, images, colours, fonts, and page sections in a visual editor. Sections can be added, reordered, or hidden, and changes are saved automatically. Sites can be published to a free subdomain or, on paid plans, a custom domain with HTTPS. Features include image uploads, forms with an inbox and CSV export, HTML export, and, on the Pro plan, AI writing tools and privacy-friendly analytics. The service supports pages for product launches, waitlists, portfolios, personal profiles, newsletters, events, local businesses, weddings, and other uses. The typical workflow is to select a template, customize the page, choose a URL, set its title and description, and publish it. Form submissions are delivered to the user’s inbox. OnePageSiteBuilder offers a free plan, a Pro plan at $9 per month, and a Business plan at $19 per month. The free plan does not require a payment card, and subscriptions can be upgraded or cancelled. Online store checkout, custom code, multi-page sites, and team accounts are listed as not yet available.
