Lucia Auth is an open-source authentication library that allows developers to handle sessions with various JS runtimes and integrate with multiple databases and ORMs. This makes it a strong choice for open-source projects where flexibility and control over the authentication process are key. On the other hand, Kinde does not emphasize open-source features but offers a generous free plan and a cost-effective Pro plan, making it suitable for projects that prioritize cost and ease of use. If open-source and flexibility are your primary concerns, Lucia Auth might be the better option.

Kinde has a generous free plan that supports up to 10,500 Monthly Active Users (MAU), after which it charges $0.0175 per additional MAU. Its Pro plan costs $25/month. Lucia Auth is an open-source library, which means there are no licensing fees, but the overall cost will depend on the hosting, database, and other infrastructure choices you make. For projects with a large number of users and limited budget, Kinde's pricing model may be more predictable and cost-effective.

Lucia Auth offers great flexibility as it works with any JS runtime (Node.js, Bun, Deno, Cloudflare Workers) and integrates with multiple databases like MongoDB, PostgreSQL, MySQL, and SQLite. It is also fully typed, which can enhance developer experience and code reliability. Kinde, while straightforward and cost-effective, does not offer the same level of flexibility in terms of runtime and database integrations. If flexibility across different environments and databases is important, Lucia Auth is the more flexible option.
