@utilcn

Fullstack shadcn registry focused on backend utility scaffolding for Next.js/TypeScript projects rather than visual components. Provides: string helpers (camelCase, kebab-case, PascalCase, snake_case, capitalize, truncate, reverse), S3-style file storage utilities with presigned upload/download URL builders plus ready-made React upload/download components and hooks, a ChatGPT MCP widget bundle (frontend UI, build tooling, shared hooks/types, backend server scaffold, sample MCP tool), and a Zod-powered server environment validator for typesafe env configuration. Free and open-source. Use for: bootstrapping the backend plumbing of a new full-stack app — file uploads, AI widget scaffolding, and typed secrets — without reinventing the boilerplate.
