Better Auth is a new authentication framework for TypeScript applications, designed to simplify and streamline the often complex process of user authentication. It offers a drop-in solution with pre-built UI components, backend logic, and integrations for popular databases and authentication providers like OAuth. The framework aims to handle common authentication flows like signup, login, password reset, and multi-factor authentication, allowing developers to focus on building their core product features rather than reinventing the authentication wheel. It also prioritizes security best practices and provides customizable options for adapting to specific application needs.
This Hacker News post announces the launch of "Better Auth," a new authentication framework specifically designed for TypeScript applications. Developed by a Y Combinator (YC) Winter 2025 batch company, Better Auth aims to streamline and simplify the often complex process of implementing authentication and authorization. The framework boasts a developer-centric design, emphasizing ease of use and rapid integration. It provides pre-built UI components and backend logic to handle common authentication flows, such as sign-up, sign-in, password resets, and multi-factor authentication (MFA).
The post highlights several key features that differentiate Better Auth from existing solutions. These include a type-safe API powered by TypeScript, which helps prevent common authentication errors and improves developer productivity. The framework also promises a seamless developer experience with features like auto-generated documentation and streamlined configuration.

The closed-source nature of the project also raised questions about community involvement and future development. Finally, a few commenters offered feedback on the website's design and user experience.
The Hacker News post for "Launch HN: Better Auth (YC X25) – Authentication Framework for TypeScript" has generated a moderate amount of discussion, with several commenters expressing a range of opinions and concerns.
Several users question the value proposition of "Better Auth," particularly in a space already crowded with authentication solutions. They express skepticism about what genuinely differentiates it from existing options like NextAuth.js, Auth.js, and Firebase Auth. Some commenters suggest the core offering isn't particularly novel and doesn't justify the "better" claim. One commenter specifically asks for clarification on how it improves upon existing solutions, particularly regarding database integrations and user management aspects.
Performance concerns are also raised, with some users questioning the overhead introduced by the framework and its impact on application speed. One commenter highlights potential issues related to running serverless functions for every authentication request.
A few commenters point out the lack of clear pricing information, which hinders their ability to assess the framework's suitability for their projects. The absence of a self-hosting option is also mentioned as a potential drawback.
There are also some positive remarks. A commenter mentions appreciating the focus on TypeScript and the developer experience. Another commenter expresses interest in learning more about the framework's internal workings.
Several users engage in a discussion about the challenges and nuances of authentication in general, touching upon topics like session management, OAuth flows, and the complexities of handling different identity providers. Some commenters share their experiences and preferences regarding specific authentication libraries and strategies.
Finally, there's a brief discussion about the marketing and positioning of the product. Some users critique the "Better Auth" name, finding it somewhat presumptuous, while others discuss the difficulties of standing out in a competitive market. One commenter suggests focusing on specific niche features or target audiences might be a more effective approach.
Overall, the comments reflect a cautious reception to "Better Auth." While some express interest and appreciate the TypeScript focus, many remain skeptical about its claimed advantages and require more information regarding pricing, performance, and specific features to make a proper assessment.
