Universal, standards-based auth provider.

Universal: You can deploy it as a standalone service or embed it into an existing application. It works with any framework or platform.
Self-hosted: It runs entirely on your infrastructure and can be deployed on Node.js, Bun, AWS Lambda, or Cloudflare Workers.
Standards-based: It implements the OAuth 2.0 spec and is based on web standards. So any OAuth client can use it.
Customizable: It comes with prebuilt themeable UI that you can customize or opt out of.
