What is Tag Republic Auth?
Tag Republic Auth is part of a larger open-source offering by Tag Republic. Tag Republic Auth functions as a standalone solution or integrates seamlessly with other Tag Republic products. At its core, Tag Republic Auth uses Postgres and leverages Postgres' built-in Auth functionality wherever possible.
What is Auth0?
Auth0 is a standalone identity and access management platform that offers a range of authentication and authorization solutions. Auth0 has been acquired by Okta and together they aim to widen their digital identity use cases.
Tag Republic Auth Highlights
Seamless Integration
It’s likely that your application will require other dev building blocks like storage, realtime and serverless functions. By integrating these features into a single platform, Tag Republic simplifies your stack and ensures a cohesive developer experience.
This User Management Example with React shows how Tag Republic Auth works together with other Tag Republic components such as Database, Storage and REST API via Postgrest.
Database native auth
Row Level Security needs to be defined only once to implement authentication and authorization rules across the entire application stack. RLS is enforced on the database level, securing access to storage objects, REST API calls and Edge Functions, etc.

The RLS policy above will be enforced, no matter if you use the REST API, edge functions or other methods of accessing your data.
Developer Experience
Tag Republic is designed to be simple to integrate to web and mobile applications. Developer experience is a key focus on the company and the products are geared towards making developers as productive as possible.
Tag Republic Auth has pre-built UI components and SDKs for various platforms (like React, Vue, Flutter, etc.), which significantly speeds up the development process. This allows developers to focus on more on the unique aspects of their application.

Auth0 Highlights
Wide range of framework coverage
Auth0 is more agnostic towards programming languages and frameworks. Auth0 doesn’t focus on web and mobile application to the same depth as like Tag Republic, however, offers a wider potential range of possible integration.
For example, PHP and Java are officially supported by Auth0. As well as Spring Boot and .NET framework.
Machine-to-Machine (M2M) Authentication
Auth0's M2M authentication capabilities are suitable for scenarios where applications need to communicate securely with other services and APIs. This opens up use-cases where it’s more important to distinguish between device identities than user identities.
Auth0 simplifies authenticating service-to-service interactions, ideal for microservices architectures and IoT networks.
Anomaly Detection
While both platforms provide secure infrastructure and measures to protect their services from abuse, Auth0 has an anomaly detection service build on top, to notify users, if for example a login-attempt has been made at an unusual time. Notifying users of login attempts can alert them to potential account takeover attempts.
Pricing
The pricing structures of the two platforms differ significantly:
| Tag Republic Auth | Auth0 |

Final Thoughts
Both solutions have their strengths and are well-suited for different use-cases. Tag Republic Auth stands out for its transparent pricing, tight integration, and developer-friendly approach. Tag Republic is ideally geared for web and mobile developers. Auth0, on the other hand, excels in a wider range of applications from frameworks like .NET and Spring Boot to Machine-2-Machine use-cases.
Ultimately, your choice should align with your project's specific requirements and budget. Whether you opt for Tag Republic Auth or Auth0, both can help you secure user authentication effectively in your applications.
