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.

Here are some of the components you get out-of-the-box:

Here is the user/project management dashboard:

• Composable React components & hooks
• OAuth (Google, Facebook, GitHub, etc.)
• Magic link and email password authentication (with email verification and password reset)
• Easy to set up with proxied providers (no need to sign up and create OAuth endpoints yourself on all the providers)
• User management & analytics
• Teams & permissions
• User-associated metadata with client-/server-specific permissions
• Out-of-the-box dark/light mode support
• Fully customizable UI, or build your own UI with our functions like signInWithOAuth
• 100% open-source!

We all know how much overhead there is when starting a new project. Developers need to handle so many things that aren't even part of their core business, like user authentication, user profiles, payments, dashboards, hosting, and more. Our vision is to build a full-stack framework that handles all of this out-of-the-box with less than 10 minutes of setup, so developers can focus on what they really want to build. Authentication is the first step towards this vision.

• Fully API endpoints with OpenAPI schema
• Webhooks
• Two factor authentication
• Backend SDKs for Python
• User analytics (retention, DAU/MAU, user segments, etc.)
• Integration with Postgres DB

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:

npx @stackframe/init-stack@latest

You will then be guided through the installation process.

For further configuration and usage, refer to our documentation.

• Next SaaSkit
• Stack Exmaple

This is for you if you want to contribute to the Stack project or run the Stack dashboard locally.

Please read the contribution guidelines before contributing.

• Node v20
• pnpm v9
• Docker

Pre-populated .env files for the setup below are available and used by default in .env.development in each of the packages. You should copy all the .env.development files to .env.local in the respective packages for local development.

In a terminal, start the dependencies (Postgres and Inbucket) as Docker containers:

docker compose -f dependencies.compose.yaml up

Then open a new terminal:

pnpm install

# Run build to build everything once
pnpm run build

# initialize the database and seed it with some data
pnpm prisma db push
pnpm prisma db seed

# Run code generation (repeat this after eg. changing the Prisma schema). This is part of the build script, but faster
pnpm run codegen

# Start the dev server
pnpm run dev

# In a different terminal, run tests in watch mode
pnpm run test

You can now open the dashboard at http://localhost:8101, API on port 8102, demo on port 8103, docs on port 8104, Inbucket (e-mails) on port 8105, and Prisma Studio on port 8106.

Your IDE may show an error on all @stackframe/XYZ imports. To fix this, simply restart the TypeScript language server; for example, in VSCode you can open the command palette (Ctrl+Shift+P) and run Developer: Reload Window or TypeScript: Restart TS server.

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

pnpm run prisma studio

If you make changes to the Prisma schema, you need to run the following command to create a migration:

pnpm run prisma migrate dev
