# The technologies that make up a Remix Supabase application > MakerKit uses Remix, Supabase, Tailwind CSS, Zod, React Query, Pino, Radix UI, Typescript and Cypress to build wonderful SaaS applications *Canonical: https://makerkit.dev/docs/remix-supabase/getting-started/technical-details* --- MakerKit is built primarily with Remix, Supabase, and Tailwind CSS. Under the hood, there are many more libraries and architectural decisions you should know. ### 1) A Scalable Remix Application The codebase is entirely built with [Remix](https://remix.run). The front end is fully built with React, leveraging React Hooks and the best practices available today. ### 2) Built on top of Supabase [Supabase](https://supabase.com) is an open source Firebase alternative, a great choice for a backend for a SaaS application. MakerKit uses Supabase for Authentication, Database (Postgres) for storing data and Storage for storing files. This kit **does not use Prisma**. We will release a Prisma version in the future. ### 3) Theme built with Tailwind 3 The bulk of the application's theme, built with [Tailwind 3](https://tailwindcss.com/), is stored in three CSS files rather than HTML. It may sound like a bad practice, but we approached this way to help you find and edit the theme's CSS in one single place. We designed the theme in light and dark, so you can choose to use both according to your user's OS settings or manage it using a local cookie. ### 4) Radix UI UI Components All the kits use [Radix UI](https://radix-ui.com), arguably the best headless UI library for React. The components are styled using Tailwind CSS. Many components are inspired by the template made by [Shad CN](https://ui.shadcn.com/). We recommend taking a look if you want to build your own components. Some components are still using Headless UI, but will be phased out in the future. ### 5) Fully and Strictly Typed with Typescript We wrote every single line of code with *strictly-typed Typescript* both on the client and server side. ### 6) Payload validation with Zod The API endpoints are **validated and protected with [Zod](https://github.com/colinhacks/zod)**, which also helps with strong-typing. ### 7) E2E testing with Cypress We ship MakerKit with [Cypress](https://www.cypress.io/), likely the most popular E2E testing framework. We made lots of examples and utilities to change the tests as you develop your application. ### 8) Linted with EsLint and formatted with Prettier We lint the codebase with **a very strict EsLint configuration**, but we distribute it with less strict params so that it won't be in your way as you're experimenting with the starter. We will show you how to add stricter parameters if that's your thing, but we do not recommend jumping head-in with it. It's much better to activate the stricter configuration once you have already shipped the product and are looking to stabilize it. Furthermore, the codebase is **formatted with Prettier** automatically. ### 9) Multi-language by default with remix-i18n We configured the application to be translated by default thanks to the `remix-i18n` package. All the application's strings are translated by default, so you can easily extend it to other languages if necessary. Using translation files can help you if you want to **translate your apps in multiple languages**, but it also allows you to find the text strings you want to replace. In this way, you do not need to change strings in the codebase, but they're **neatly organized in JSON files**. ### 10) Logging with Pino MakerKit uses [Pino](https://github.com/pinojs/pino), a lightweight logging library. API errors are logged with just enough information to help you debug your API routes. ### 11) React Query MakerKit uses Tanstack's React Query to coordinate data fetching and caching.
