Auth0, part of Okta, offers a comprehensive identity management solution with features such as social login, bot detection, UI components, single-sign-on, and multi-factor authentication. However, it can be relatively expensive, with costs reaching $1400/month for 20,000 monthly active users (MAUs). On the other hand, Appwrite is an open-source platform that provides not just authentication but also databases, storage, and functions. Appwrite's free plan is highly generous with 75,000 MAUs at no cost, and its Pro plan is only $15/month. Appwrite supports various login methods, including email and password, phone authentication, magic links, email OTP, anonymous login, JWT login, SSR login, custom tokens, and two-factor authentication. The choice between the two will depend on your specific needs and budget constraints. If you need a more extensive development platform and have a limited budget, Appwrite might be the better option. If you require a highly specialized and comprehensive identity management solution, Auth0 could be worth the investment.
