Easy Auth in React
The Supabase Auth UI Library and MUI Toolpad Core are two common quick-start options for adding authentication to a React app without building everything from scratch.
The Supabase Auth UI Library is a drop-in solution for apps using Supabase. It handles sign-in, sign-up, OAuth, and session management automatically, including things like redirects and session persistence. Instead of writing auth logic manually, the component manages it for you. It’s best suited for prototypes, MVPs, or apps fully built around Supabase.
The MUI Toolpad Core takes a different approach. It’s designed for building apps with MUI and integrates authentication through libraries like Auth.js. Its main advantage is consistency—it uses MUI’s design system so your login screens match the rest of your UI. It’s often used for internal tools and enterprise dashboards where design consistency matters.
In practice, Supabase Auth UI prioritizes speed and tight backend integration, while Toolpad Core prioritizes UI consistency and flexibility across auth providers.
You can also build authentication manually using Supabase, Auth.js, or similar libraries without any prebuilt UI. This gives you full control, but it takes significantly more time to build, wire up, and maintain.
