Site Knock: The container-first SaaS starter kit

Hey Product Hunters 👋🔥 Today I’m announcing Site Knock, not a full launch yet! Right now, I’m opening the waitlist to start building around the product before the full release goes live 🚧 Site Knock is a container-first SaaS starter kit for developers who want to ship faster without spending weeks wiring up the same foundations every single time. Think: ⚡ Next.js 16 + React 19 ⚙️ Express 5 backend 🔐 auth, sessions, RBAC, orgs, 2FA 💳 Stripe billing 🌍 i18n + per-locale SEO 🎨 themes + branding 📦 storage 📧 email flows 🛠️ admin tooling - This will be the kicker and main USP The goal is simple: help SaaS builders skip the repetitive setup phase and start with something that already feels like a real product instead of a half-connected boilerplate. So why launch now ? Because I want to validate the message early, meet the right early users, and shape the product with real feedback before going live 🧠 This launch is really about: 🚀 testing demand 🎯 finding the right audience 💬 hearing what features matter most 📬 growing the early-access waitlist If you’re building a SaaS, I’d love for you to check out the homepage, join the waitlist, try out the demo site install, and tell me what would make a starter kit feel like an instant yes for you 🙏 If this resonates, your support today would mean a lot 💙
