BuilderKit vs SaaS UI
Compare BuilderKit and SaaS UI side-by-side. We've analyzed features, pricing, and capabilities to help you choose the best boilerplate for your SaaS project.
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. Rather than being a minimal template, BuilderKit comes pre‑wired with modules and features that cover many needs for an AI SaaS: authentication (email, Google auth, magic‑link), payments (via Stripe or LemonSqueezy), email integrations, admin dashboard, SEO‑friendly landing pages & waitlist pages, and even pre-built AI‑app demos. 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
SaaS UI
Saas UI is a premium starter kit / boilerplate built on Next.js (with React + TypeScript) designed specifically for building SaaS and B2B web applications quickly and with solid structure. It pairs a rich UI/design system with the backend scaffold and common SaaS plumbing so you don’t have to build everything from scratch. Right away you get a full-featured component library and design system prebuilt UI components, themes, responsiveness, dark/light mode support all optimized for building dashboards, admin panels, web apps or SaaS products. On the functionality side, Saas UI ships with support for user authentication (login/signup, social login options, account management), workspace/team/organization support (workspaces, team invites, role-based access), subscription & billing flows with Stripe (subscription plans, per‑seat or team‑based billing, metered usage and entitlement management), and built‑in support for multi-tenancy / per‑workspace billing/perms. The stack includes a modern backend API layer (via tRPC), a database setup that works with PostgreSQL (and other options), and a dev environment optimized for productivity (TypeScript, Turborepo/monorepo friendly configuration, sensible defaults for linting/formatting).
