Auth0 by Okta is a comprehensive identity management solution that offers a wide array of features including social login, bot detection, UI components, anonymous users, single-sign-on, and multi-factor authentication. It is designed to handle large-scale applications but comes at a relatively high cost, with 20,000 MAUs costing $1400/month. On the other hand, Auth.js is an open-source authentication library originally built for Next.js and is completely free to use. While it supports over 80 integrations and can be used with various databases like MySQL, Postgres, MSSQL, and MongoDB, it may require more configuration and maintenance effort. Therefore, if budget is a constraint and you are comfortable with some additional setup, Auth.js could be a better option for large-scale applications. Otherwise, Auth0 provides a more out-of-the-box solution.

For small to medium-sized businesses, cost-effectiveness is a crucial factor. Auth.js, being an open-source library, is free to use, making it a highly cost-effective option. It also offers a wide range of integrations and is compatible with various databases, providing flexibility for different types of applications. Auth0, on the other hand, offers a free tier with 7,500 MAUs but becomes relatively expensive as user numbers grow, costing $1400/month for 20,000 MAUs. Therefore, for small to medium-sized businesses, Auth.js is generally more cost-effective unless the advanced features and ease of use offered by Auth0 are a necessity.
