What to Use Instead of Supabase for Authentication in 2026

Clerk, Better Auth, and WorkOS solve different problems

I would not look for a universal winner here: Clerk removes the most work from a product team, Better Auth gives you control over the stack, and WorkOS targets enterprise identity. As of September 2026, these are three distinct architectural choices rather than interchangeable login wrappers.

Clerk works well when you need to launch authentication quickly with a ready-made interface. Clerk’s pricing page lists the Hobby plan as free for up to 50,000 MRUs, while Pro costs about $25 per month, or $20 with annual billing, plus roughly $0.02 for each additional MRU. Its product documentation also lists MFA, organizations, user management, and SSO and SCIM options.

Clerk’s main value is not password validation itself, but eliminating frustrating product work: forms, sessions, account recovery, and the user dashboard are already assembled. The trade-off is clear: costs grow with retained users and enterprise add-ons, while a critical part of the application becomes tied to an external platform.

Better Auth takes the opposite approach. The project describes itself as a free, open-source authentication toolkit that can run on your own infrastructure and be adapted to non-standard processes. Savings on a platform subscription can easily become costs for databases, observability, updates, security, and on-call operations.

WorkOS is a more natural fit for B2B products where customers bring their own identity providers. WorkOS documentation emphasizes SSO, SCIM, directory sync, organizations, and AuthKit. According to published materials, AuthKit is free up to 1,000,000 MAUs; each additional million costs about $2,500 per month. SSO and SCIM are priced separately at around $125 per connection.

All prices are a snapshot from September 2026. They change faster than application architecture, so comparing free limits alone is risky.

The decision is driven by future operations, not login

The practical picture is simple: Clerk wins on speed and polished out-of-the-box UX, WorkOS is strong for enterprise integration, and Better Auth minimizes vendor dependence. This is where it gets interesting: the cheapest option at launch does not necessarily remain cheap once engineering time is included.

I would first evaluate the organization model, session lifecycle, user export, and behavior during provider outages. For B2B, tenant isolation, SSO, and directory synchronization are especially critical; for consumer products, a smooth sign-in experience and predictable pricing matter more.

This is not a story about choosing a fashionable service instead of Supabase. The real choice is between delegating responsibility externally and being ready to own one of the most sensitive parts of the system yourself. Authentication rarely breaks a demo, but it reveals the cost of architectural compromises exceptionally well after launch.

We previously covered how API security alerts, logging, and separated environments shape compliance decisions. The same controls matter when evaluating authentication providers such as Clerk, Better Auth, and WorkOS.
