What is Tesseral

Tesseral is a complete authentication system designed for business-to-business software applications. It handles user login, permission management, and security features so developers can focus on building their main product.

The platform supports multiple ways for users to log in, including passwords, magic links, Google, GitHub, and Microsoft accounts. For larger companies, it includes enterprise features like SAML and OIDC single sign-on, which lets employees use their work accounts.

Tesseral is open-source with an MIT license, meaning anyone can view, modify, and use the code. You can choose between using their managed cloud service or running Tesseral on your own servers. The platform works with popular frameworks like React, Next.js, Python, and Node.js through ready-made code packages.

FAQ's About Tesseral

Is Tesseral really free?
Yes, Tesseral offers two free options. The Community plan lets you download and self-host the open-source software with no license costs. The Studio plan provides a free managed service supporting up to 200 active users and 50 organizations, perfect for startups and small applications.
What makes Tesseral different from Auth0 or other authentication services?
Tesseral is open-source, which means you own your implementation and can host it anywhere. It's built specifically for B2B applications with features like organization management and self-service admin panels. You can start free and scale without vendor lock-in since the code is available on GitHub.
Do I need to be a security expert to use Tesseral?
No, Tesseral handles complex security tasks for you. The platform uses secure defaults and provides ready-made code that integrates in minutes. While basic web development knowledge helps, you don't need deep security expertise to implement enterprise-grade authentication.
Can my customers manage their own users?
Yes, Tesseral includes built-in admin interfaces that your customers can use. Each organization can invite team members, remove users, configure their login methods, and set up single sign-on without needing your help. This reduces support burden while giving customers control.
What programming languages and frameworks does Tesseral support?
Tesseral provides official SDKs for React, Next.js, Go, Python (Flask), and Node.js. Since it's API-first, you can use it with any programming language or framework by making standard HTTP requests. The open-source nature also means the community can build additional integrations.
