Quick Overview
BuilderKit
BuilderKit.ai is a boilerplate / starter‑kit built with Next.js + Supabase + Tailwind CSS + TypeScript, aimed at helping developers launch AI‑powered SaaS/web applications quickly.

On top of that, BuilderKit bundles 10‑15+ ready-to-use AI tools / applications: for example chat, image generation, PDF‑chat, voice transcription, image‑enhancing / upscaling, and more, so you don’t just get a skeleton, but a suite of working AI‑powered features you can build on or customize. he code is distributed via a GitHub repo, and once set up (with environment variables, dependencies installed, etc.) you can run and deploy the app commonly on platforms like Vercel.
Key Features
Solid
Solid is a SaaS‑oriented boilerplate / starter kit built on Next.js + React + TypeScript, designed to furnish most of the foundational pieces a modern web/SaaS project needs from frontend and backend structure to authentication, payments, content and UI components. Solid comes bundled with a wide range of features useful for SaaS or web‑app development: secure user authentication via NextAuth (supporting social login, magic‑link, password reset, etc.), database integration (designed to work with relational DB like PostgreSQL, via ORM or your preferred provider), subscription/payment support through Stripe, and blog/content support via a CMS (for instance Sanity for blog management), enabling dynamic content and documentation out-of-the-box. On the front‑end side, Solid offers a comprehensive UI kit and pre-made pages: landing page templates, pricing and business pages, blog lists and post pages, documentation pages (via MDX), auth flows pages, and responsive design with modern styling. It also includes performance & SEO optimizations, dark‑mode support, search integration (via Algolia for search), transactional email support, newsletter integration (e.g. via Mailchimp), and a collection of reusable UI components based on modern best practices, which can speed up development while maintaining code quality and scalability.
