Launch your startup
in days, not months

You can use it, but Shipped is based on Next.js, React, and TypeScript (JavaScript).
If your tech stack is based on React, but not on Next.js, you can roughly reuse 80% of the codebase.
If your tech stack is based on TypeScript/JavaScript, but not on Next.js and React, you can roughly reuse 20% of the codebase.

It's much more. You'll get a set of reusable React components and TypeScript business logic code, to build your startup quickly.
The components include all the basic UI components like buttons, forms, inputs, modals, navigation (coming from ChakraUI). But Shipped provides additional product-oriented components, like: hero section, pricing plans, wait list, testimonials, account menu, call to action, and many more (check them all on the documentation)

I regularly update Shipped, both the code and the documentation, and based on the feedback I receive on the Discord community.
This means that you can expect weekly updates, and security updates going forward.

After you get access to the repo, Shipped is yours forever, so it can't be refunded.
The customers of Shipped launch a startup in 7 days on average, and you'll always get access to the Discord community for support.

Shipped is based on ChakraUI but you can install any UI libraries and use their UI components. Consider that most of the components provided by Shipped are developed using ChakraUI so it is not feasible to completely remove ChakraUI.
But you can install other libraries and use their components, like DaisyUI, TailwindUI, Joy UI, or shadcn.
Shipped also supports TailwindCSS for styling, so you can use TailwindCSS based components or UI libraries.

Yes. Shipped currently implements Magic Link and Email & Password authentication using Supabase.
NextAuth is a free and open-source library and it supports many authentication methods. It was selected to avoid any vendor lock-in.
The philosophy of Shipped is to never locks in with any architectural decision, so you can replace NextAuth with another authentication service like Auth0, Clerk, AWS Cognito.

Yes. Shipped currently implements Lemon Squeezy because it is a Merchant of Records (not only a payment provider). This means that Lemon Squeezy handles the taxes for the sales you'll make all over the world, while you need to focus only on paying the taxes on your payouts.
You can use any other payment provider you prefer, including Stripe, but you'll need to implement the webhook handler to manage the Stripe events, while you can reuse almost all the database tables.

I personally use Vercel, because it is very easy to use, and scales very well. But there are other options and different aspects to consider. I wrote a detailed article about it, so you can take the best decision possible. You can find it here.

You can check out the documentation to see what you'll get.
