Quick Overview
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.
Key Features
Uni-Stack
Uni‑Stack is a free, open‑source, production‑ready full‑stack framework for building universal React Native + web apps with a single codebase. It uses modern, type-safe technologies — including Expo (with universal support for iOS, Android and web), Prisma for database management, tRPC for end-to-end type‑safe APIs, and TypeScript for strong typing throughout. With Uni‑Stack you get an integrated stack where routing, UI, database logic, API calls, queries and mutations are all type-safe and unified. It supports multiple UI system options (e.g. Nativewind, Tamagui, gluestack‑ui), giving flexibility in theming and design while keeping a consistent architecture.
