Firebase and Kinde both offer robust user authentication solutions, but they cater to different needs. Firebase, developed by Google, is an entire app development platform that includes user authentication along with many other features like storage and cloud functions. It offers a generous free tier with 50,000 MAUs and lower costs per additional MAU as you scale. Firebase supports multiple authentication methods including email, password, phone, magic links, and social identity providers. Kinde, on the other hand, provides a generous free plan with up to 10,500 MAUs and a straightforward pricing model. While Firebase is more feature-rich and scalable, Kinde might be a simpler and more cost-effective solution for smaller applications.

For scaling beyond the free tier, Firebase tends to be more cost-effective. Firebase's pricing starts at $0.0055 per MAU and can go as low as $0.0025 per MAU as you scale to millions of users. Kinde, on the other hand, charges $0.0175 per additional MAU beyond 10,500. Therefore, for larger-scale applications, Firebase offers a more competitive pricing structure.
