Ory and Clerk offer different strengths for user authentication. Ory is an API-first identity manager that supports a wide range of programming languages but does not offer a free tier, starting at $29/month for 1,000 daily active users (DAUs).

Clerk offers a free tier of up to 10,000 monthly active users (MAUs) and a Pro tier at $25/month with additional costs for enhanced features. If cost and a free tier are important, Clerk might be the better option. However, if you need support for a wide range of programming languages and advanced authentication features, Ory could be more suitable.
