cult-ui

Cult UI (cult/ui) is an open-source component collection for design engineers. Its core offering is accessible, customizable components that can be copied and pasted into apps, with the stated goal of helping developers build their own component library. Components are styled with Tailwind CSS and are described as fully compatible with shadcn, so integration follows familiar copy-paste patterns. The project is licensed under MIT and includes documentation at cult-ui.com/docs plus a contributing guide. Beyond base components, the README highlights an AI SDK Agents section with 92+ AI agent patterns. These feature live interactive previews and can be copied and pasted, installed with shadcn, downloaded as a Next.js app, or opened in v0. Featured examples include a Competitor Research Agent using Firecrawl Map and Parallel Scrape, a Data Analysis Agent for CSV/JSON analysis and visualizations, an Accessibility Audit Agent for WCAG 2.1 checks, a Table Editor Artifact with AI chat, a Branding Agent for extracting design systems, and a Chart Generation Artifact. There are also four full-stack agent templates: Ecommerce Multi-Agent, AI SDK Agent Platform, Sub Agent Starter, and Multi Tenant Better Auth Chat, each listing stacks such as Next.js, AI SDK Tools, TypeScript, Tailwind, Zustand, Framer Motion, Workflow Dev Kit, Better Auth, Drizzle, PostgreSQL, Stripe, and pgvector. The README also lists Cult Pro premium blocks and marketing patterns, including Gemini Flash Image Editor, several agent patterns (multi-step tool, evaluator-optimizer, orchestrator, routing), and Gemini Flash Text. Six starter templates are shown: Logo GPT, Directory, Travel Stash, Landing Page, Cult SEO, and Manifest, with stacks involving Next.js, Tailwind, OpenAI, Supabase, Claude AI, PWA, and web scrapers.
