BuilderKit.ai: Accelerate AI SaaS Development with a Fully-Featured Next.js Boilerplate

BuilderKit.ai is a powerful, modular Next.js AI boilerplate designed for developers to rapidly build and launch AI-powered SaaS applications. It provides a production-ready foundation with server-side rendering, edge functions, and clean, typesafe TypeScript code, all styled with Tailwind CSS and Shadcn UI for a polished, responsive UI—complete with dark mode and real-time webhook support. Seamlessly integrated with Supabase for authentication, user management, and secure data handling, it also supports top-tier AI services like OpenAI, Claude, GPT-4, Whisper, Llama, Mistral, and Stable Diffusion, enabling developers to incorporate chat, text generation, image generation, speech-to-text, and text-to-speech modules out of the box. Additional features include Stripe and LemonSqueezy payment integration, email workflows via Loops and Resend, SEO-optimized components with meta and OpenGraph tags, automated sitemap generation, and a full admin dashboard for managing users, tokens, and subscriptions. With 14 pre-built AI apps—such as Content Writer, Voice Transcription, Chat with PDF, and Headshot Generator—and 13–15 customizable landing pages and waitlist templates, BuilderKit.ai removes the friction of starting from scratch. The platform is fully deployable on Vercel with no API timeouts, and users receive a private GitHub repository with code they can use commercially—while retaining full ownership of their final product. All plans offer a pay-once, use-forever licensing model, making it a cost-effective solution for long-term projects.
