## BuilderKit

BuilderKit is a commercial, one-time-purchase codebase for developers who already know React and Next.js and want to skip the repetitive setup work of a new SaaS product. Instead of wiring authentication, Stripe or Lemon Squeezy billing, database tables, email flows and an admin panel from scratch, you get a documented GitHub repository that already contains those pieces and is designed to be customised and deployed to Vercel.

The kit's distinguishing feature is its library of AI modules and pre-built demo apps. Text generation, chat, image generation, speech-to-text and text-to-speech modules are wired to major model providers including OpenAI, Anthropic, Google, Mistral, Deepgram, Pinecone and Stable Diffusion, so you can swap providers rather than building each integration yourself.

The licence is deliberately restrictive in one respect: you can build and sell your own products on top of BuilderKit, but you cannot repackage it as a competing starter kit. The team also offers paid custom builds for companies that want a bespoke AI app on top of the same foundation.

**Pricing & Plans:** One-time purchase rather than a subscription. A Landing Pages tier is listed at $99, a Starter tier at $149 and a Pro tier at $199, each described as pay once and use forever, with an optional coupon discount at checkout. Custom AI app builds start at $1,999 by arrangement.

- **Complete Next.js base:** A typesafe TypeScript and Next.js codebase with server-side rendering, clean components, Postgres tables on Supabase and row-level security already configured.
- **Ready-made AI modules:** Chat, text generation, image generation, speech-to-text and text-to-speech modules with support for major model providers, so you can pick and swap LLM or media APIs.
- **Payments, auth and email:** Supabase authentication with Google sign-in and magic links, Stripe and Lemon Squeezy checkout, plus Loops or Resend transactional email integrations.
- **Landing pages and admin panel:** Pre-built marketing pages, waitlist templates, SEO metadata, automated sitemaps and an admin dashboard for managing users, usage and plans.
- **Sample apps and documentation:** Multiple demo applications plus simple documentation and tutorials that show how each module is assembled and deployed.

**Strengths:** Saves substantial setup time by bundling auth, billing, database and AI modules in one documented repository; TypeScript throughout with a clean, modular structure that is straightforward to extend; Supports several model providers instead of locking you to a single vendor; One-time payment model instead of an ongoing subscription

**Limitations:** Requires existing React and Next.js experience to be useful; No refunds are offered because it is a downloadable code product; You cannot repackage the kit itself as a competing starter kit product

## SUPANEXT

SUPANEXT is a Next.js and Supabase starter kit designed to get money-making projects off the ground fast. Rather than rebuilding the same foundations for every new idea — authentication, database, payments, subscriptions, credits, a landing page and a blog — you start from a complete, production-ready codebase and spend your time on the product itself.

It is built on a modern stack: Next.js 15 and Tailwind CSS 4, Supabase for auth and data, Stripe or LemonSqueezy for payments, and Resend for transactional email. For AI applications it includes working examples out of the box, such as an AI image generation demo and an AI chat, with OpenAI and Replicate integrations and a credit system for monetising AI usage.

SUPANEXT also leans into growth. The landing page and blog are optimized for search engines, and a built-in AI blog generator helps you produce and optimize posts to rank better. The project is a one-time purchase with lifetime access, source-code access, documentation, all current and future features, and lifetime updates, created by Jake Prins.

**Pricing & Plans:** One-time payment with lifetime access. The site shows early-bird pricing starting at $99 for the first 10 users, rising through $149 and $229 to a $299 final price. Includes source code, documentation, AI examples, free lifetime updates, priority support and commercial use.

- **Authentication and database:** Email and Google sign-up, login and password reset flows wired to Supabase out of the box.
- **Payments and subscriptions:** Stripe and LemonSqueezy payment integrations with subscriptions and a pre-built credits management system.
- **AI building blocks:** AI image generation and AI chat examples using OpenAI and Replicate, ready to extend.
- **SEO-optimized landing and blog:** A modern, responsive landing page and blog, both optimized for search engines.
- **Themeable design system:** Light and dark mode with easy primary-color theming through a few variables.

**Strengths:** Saves weeks of setup across auth, payments, subscriptions and pages; Native AI examples (image generation, chat) with OpenAI and Replicate; SEO-optimized landing page and blog with an AI blog generator; One-time price with lifetime access, updates and commercial use

**Limitations:** You still need development knowledge to customise a boilerplate; One-time price is an upfront cost versus free starter templates; Not a no-code builder — it is code you extend yourself
