Baseplate

Baseplate is a Next.js 16 starter kit for launching SaaS products faster. Key features: • Supabase authentication ready to use • Stripe payments and subscription billing • Drizzle ORM for type-safe database access • Large language model integrations for OpenAI and Anthropic • Streaming responses and credit tracking • Rate limiting and a ready-to-use dashboard. Instead of spending weeks wiring up the basics, you start with a working foundation that handles sign-in, billing, data access, and usage limits from day one. The code is organized so you can swap components, extend features, and ship your own product logic without fighting the boilerplate. The Pro edition adds retrieval-augmented generation (RAG) and agent examples along with advanced UI components for more complex interfaces. Built for indie developers, startup founders, and small teams who want to validate an idea quickly. It suits anyone building a subscription app, internal tool, or language model-powered product who would rather customize proven code than start from scratch. You receive the full source code through a private GitHub repository, with the freedom to build unlimited personal or commercial products.
