Firebase and Ory offer different strengths depending on your needs. Firebase is part of Google's ecosystem and provides a comprehensive app development platform, which includes user authentication. It has a generous free tier, supporting up to 50,000 monthly active users, and offers a variety of authentication methods including email, phone, and social providers. Its pricing is also relatively low per monthly active user as you scale. On the other hand, Ory is an API-first identity manager that supports a wide range of programming languages and offers advanced features like machine-to-machine authentication and access control. However, it does not have a free tier and starts at $29/month for 1,000 daily active users. If you need a more integrated development platform with a generous free tier, Firebase might be the better choice. If you require advanced identity management features and language support, Ory could be more suitable.

Both Firebase and Ory offer scalable solutions, but they do so in different ways. Firebase pricing starts at $0.0055 per monthly active user and decreases as you scale, making it cost-effective for large user bases. It supports a high number of monthly active users with a variety of authentication methods and integrates seamlessly with other Google services, making it a good option if you expect rapid user growth. Ory, on the other hand, starts at $29/month for 1,000 daily active users and charges $30 for each additional 1,000 daily active users. It is API-first and supports advanced features, which can be beneficial for complex identity management needs as you scale. If cost and ease of use are your primary concerns, Firebase may be the better option. If you need advanced features and are willing to invest in a more specialized solution, Ory could be the better choice.

For a startup, Firebase is generally more cost-effective due to its generous free tier and low pricing per monthly active user. Firebase provides up to 50,000 monthly active users for free, making it an excellent option for startups looking to minimize expenses while scaling. After the free tier, the cost starts at $0.0055 per monthly active user and decreases with scale. Ory, on the other hand, does not offer a free tier and starts at $29/month for 1,000 daily active users, which can be more expensive for startups with limited budgets. Therefore, if cost is a critical factor, Firebase would likely be the more economical choice.
