About

MantleKit is a Next.js SaaS boilerplate designed to reduce the setup work involved in building web applications. It includes connected systems for authentication, payments, ecommerce, CMS content management, admin dashboards, SEO configuration, support workflows, and team management. The platform focuses on common SaaS requirements that developers typically rebuild for each project, including protected routes, blog infrastructure, JSON-LD metadata, support ticket handling, and ecommerce operations. MantleKit also includes multiple frontend themes and reusable landing page sections to speed up UI development. The product is positioned as a production-ready foundation for launching SaaS applications faster, with a CLI-driven setup flow and integrations for services such as Supabase, Stripe, Lemon Squeezy, Resend, Mailgun, and Brevo.
