Stack is an open-source, self-hostable, and highly customizable authentication and user management system.

We provide frontend and backend libraries for Next.js, React, and JavaScript. You can set it up in one minute and scale with the project as it grows. Think of it as Supabase Auth or next-auth, but better.

Here is an example of the sign-up page you get out of the box:

• OAuth (Google, Facebook, GitHub, etc.)
• Email and password authentication (with email verification and password reset)
• Easy to set up with proxied providers
• User management & analytics
• Pre-built React components & hooks
• Support for static sites & single-page apps
• User-associated metadata with client-/server-specific permissions
• 100% open-source!

To get started with Stack, you need to create a Next.js project using the App router. Then, you can install Stack by running the following command:

### TODO

For setup, refer to our documentation.

This is for you if you want to contribute to the Stack project.

Make sure you have pnpm installed alongside Node v20. Next, ensure you created .env.local files by copying .env in each of the subpackages in the packages folder and filling out the variables. You will need to start a Postgres database; you can do this with the following command:

docker run -it --rm -e POSTGRES_PASSWORD=password -p "5432:5432" postgres

Then:

pnpm install

# Run code generation (repeat this after eg. changing the Prisma schema)
pnpm run codegen

# After starting a Postgres database and filling the corresponding variables in .env.local, push the schema to the database:
pnpm run prisma:server -- db reset

# Start the dev server
pnpm run dev

To do linting and typechecking:

pnpm run codegen

You can also open Prisma Studio to see the database interface and edit data directly:

pnpm run prisma:server -- studio
