About AuthOS

Our Mission

We’re building the identity infrastructure that powers modern B2B2C SaaS applications. Authentication shouldn’t be a bottleneck—it should be an enabler that lets you focus on what makes your product unique.

Why We Built AuthOS

After years of building and scaling SaaS products, we kept running into the same challenges with authentication:

• Multi-tenancy is hard: Managing authentication for multiple organizations shouldn’t require complex workarounds
• Brand consistency matters: Your users shouldn’t feel like they’re leaving your app to sign in
• Enterprise requirements are non-negotiable: SSO, audit logs, and compliance can’t be afterthoughts
• Developer experience matters: Authentication shouldn’t take weeks to implement

We couldn’t find a solution that addressed all these needs without requiring massive infrastructure investment or sacrificing user experience. So we built AuthOS.

Technology Stack

Backend: Rust

Built with Rust and the Axum framework for maximum performance and reliability. Our architecture handles millions of authentication requests daily with sub-100ms response times.

SDK: TypeScript

A zero-dependency TypeScript SDK that works in any JavaScript environment—Node.js, Deno, Bun, or the browser. No bloat, just clean, type-safe code.

Database: SQLite/PostgreSQL/MySQL

Start with SQLite for simplicity, scale to PostgreSQL or MySQL for high-availability. All three options support the same feature set.

Deployment: Docker

Containerized from day one. Deploy anywhere—a single VPS, Kubernetes cluster, or your own data center.

Open Source Commitment

AuthOS is committed to open source. Our core authentication engine is open source, and we believe in transparent, auditable security software. The enterprise features you need for scale are available in our commercial offering.

Our Values

• Security First: Every decision starts with security. No compromises.
• Developer Experience: We obsess over the developer experience because we’ve been there.
• Privacy by Design: Your data is yours. We don’t sell or share it.
• Performance: Authentication should be instant, not a bottleneck.
• Simplicity: Complex problems don’t need complex solutions.
