ORY Kratos vs Auth0: What are the differences?

Auth0 and ORY Kratos are both identity and access management solutions. Here are the key differences between Auth0 and ORY Kratos:

  1. Features and Capabilities: Auth0 is a comprehensive identity platform that offers a wide range of authentication and authorization features, including social logins, single sign-on (SSO), multi-factor authentication (MFA), user management, and identity federation. On the other hand, ORY Kratos is a modern, open-source identity and user management system. While it also supports common authentication features like passwordless logins and MFA, its primary focus is on user registration, account recovery, and account verification. ORY Kratos is designed to be easily extensible and customizable to fit specific use cases.

  2. Deployment Options: Auth0 is available as a cloud-hosted service, offering a fully managed solution that reduces the operational burden on organizations. It is deployed on Auth0's infrastructure, ensuring high availability, security, and scalability. Additionally, Auth0 provides on-premises deployment options for organizations with specific regulatory or data residency requirements. ORY Kratos, being an open-source solution, can be self-hosted on-premises or in the cloud, providing full control over the infrastructure and data. This flexibility allows organizations to tailor the deployment to their security and compliance needs.

  3. Licensing and Cost: Auth0 is a commercial solution with a subscription-based pricing model. It offers different pricing tiers based on the number of active users and additional features required, making it suitable for businesses of various sizes. Auth0's pricing includes hosting, support, and maintenance, simplifying the cost structure for organizations. On the other hand, ORY Kratos is open-source. As a result, there are no licensing fees associated. However, organizations need to consider the operational costs of self-hosting, managing, and supporting the solution.

  4. Community and Support: Auth0 offers dedicated customer support, a strong user community, and a wide range of integrations. ORY Kratos, as an open-source solution, relies on community-driven support and contributions, providing flexibility to organizations.

In summary, Auth0 is a feature-rich, cloud-hosted identity platform with commercial licensing and dedicated support, while ORY Kratos is an open-source identity and user management system with flexibility in deployment options and licensing.

and
PassportPassport

Currently, Passport.js repo has 324 open issues, and Jared (the original author) seems to be the one doing most of the work. Also, given that the documentation is not proper. Is it worth using Passport.js?

As of now, StackShare shows it has 29 companies using it. How do you implement auth in your project or your company? Are there any good alternatives to Passport.js? Should I implement auth from scratch?

I would recommend Auth0 only if you are willing to shell out money. You can keep up with their free version only for a very limited time and as per our experience as a growing startup where budget is an issue, their support was not very helpful as they first asked us to sign a commercial agreement even before helping us t o find out whether Auth0 fits our use case or not! But otherwise Auth0 is a great platform to speed up authentication. In our case we had to move to alternatives like Casbin for multi-tenant authorization!

Decisions about Auth0 and ORY Kratos

from
Amazon CognitoAmazon Cognito
to
Auth0Auth0

I started our team on Amazon Cognito because I was a Solutions Architect at AWS and found it really easy to follow the tutorials and get a basic app up and running with it.

When our team started working with it, they very quickly became frustrated because of the poor documentation. After 4 days of trying to get all the basic passwordless auth working, our lead engineer made the decision to abandon it and try Auth0... and managed to get everything implemented in 4 hours.

The consensus was that Cognito just isn't mature enough or well-documented, and that the implementation does not cater for real world use cases the way that it should. I believe Amplify has made some of this simpler, but I would still recommend Auth0 as it's been bulletproof for us, and is a sensible price.
