Authorizer

In plain words

Authorizer is an open-source authentication and authorization platform that developers can self-host and connect to their own SQL database. It handles user authentication and access control while keeping user data under the application owner's control. The solution works with any SQL database, making it suitable for teams wanting to manage their own identity infrastructure without relying on third-party services.

From the sources

Authorizer is an open-source authentication and authorization solution for your applications. Bring your database and have complete control over the user information. You can self-host authorizer instances and connect to any SQL database.

Own your identity layer. Self-host open-source auth—OAuth2, OIDC, SAML SSO, SCIM, passkeys, MFA, OpenFGA—with permission-aware AI on your own data.

The open-source auth platform you run yourself—authentication, fine-grained authorization, and permission-aware AI, with every user in your own database . Drop the Authorizer component into any app — SaaS, dev tool, e-commerce, AI product. The same login experience, always under your control. Hosted identity platforms give you dashboards, enterprise SSO marketplaces, and batteries-included UI—in exchange for running your most sensitive infrastructure on someone else's servers and paying a per-seat auth tax as you grow. Authorizer is a different tradeoff: open source and self-hosted so authentication runs where you run your product—and user records stay in your database. A category-level…from authorizer.dev

  Open Source Authentication and Authorization2022 · ▲128

  I’m Rishabh and the co-founder and CTO at https://supertokens.com (YC S20). We offer open-source user authentication and we just released our user roles product for companies implementing authorization. Our users are web developers, and a prominent and adjacent pain point for our users is authorization. Developers typically implement two independent solutions for authentication and authorization. Offering AuthN and AuthZ in a single solution is something we’ve been thinking about for the last few years. Quick primer, authentication is knowing who the user is, and authorization is…

  Permify 1.0 – Open-source fine-grained authorization service2024 · github.com · ▲154

  Permify was born out of our repeated struggles with authorization. Like any other piece of software, authorization starts small but as things grow scaling it becomes a real pain and begins to hinder product development processes. Ad-hoc authorization systems scattered throughout your app’s codebase are hard to manage, reason about, and iterate on as the company grows. Also you will need to have more specific access controls as things grow. Traditional approaches like RBAC is inefficient for defining granular permissions such as resource-specific, hierarchical, or context-aware permissions.…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
