6 free alternatives to Clerk

Logto's free tier includes up to 50,000 monthly active users, 50,000 tokens per month, 3 total applications, 1 machine-to-machine app, 3 social connectors, 1 custom domain, 1 webhook, and audit logs retained for 3 days. It also includes account APIs, user management, and one tenant member for console access. That makes it a good fit if you want a hosted auth service with clear per-account limits and a smaller, simpler surface area. It beats Clerk on tokens per month and gives a similar app and social-connector shape. It falls short on dashboard seats, impersonation, B2B add-ons, and the broader set of included auth and admin features. Switch if you mainly need a straightforward hosted identity layer and can live within tighter console and organization limits.

• Beats Clerk: 50,000 tokens per month, plus a simple hosted auth footprint with 3 apps and 1 webhook
• Falls short: Only 1 tenant member for console access, with no comparable free dashboard-seat or impersonation allowance
• Who should switch: Switch to Logto if you want a compact hosted identity service with token-based limits and do not need Clerk's team and admin headroom.

Auth0's free tier includes up to 25,000 monthly active users, 1 custom domain, passwordless authentication, unlimited social connections subject to system limitations, 5 organizations, brand customization, basic attack protection, community support, 1 enterprise connection, self-service SSO, and SCIM. It is a solid choice when you need enterprise-style identity plumbing in a hosted package and want more organization and federation features than a basic starter plan. It beats Clerk on social connection breadth and on included SCIM and self-service SSO. It falls short on user volume, requires a credit card for the custom domain, and does not give Clerk's free dashboard seats, impersonation allowance, or B2B add-on structure. Switch if your priority is identity integrations over larger free user capacity.

• Beats Clerk: Unlimited social connections, plus SCIM and self-service SSO in the free tier
• Falls short: 25,000 MAUs and credit-card verification for the custom domain, with fewer collaboration and admin freebies
• Who should switch: Switch to Auth0 if you need enterprise identity features on a free plan and can accept lower user volume.

PropelAuth's free tier includes 10,000 monthly active users, unlimited organizations, unlimited waitlist users, a custom domain, 2FA and RBAC, and customizable UIs including split-screen. It is built for B2B products that care more about organization structure and role management than raw user volume. It beats Clerk on unlimited organizations, which can matter for multi-tenant apps that expect many customer workspaces. It falls short on total free user capacity, impersonation, dashboard seats, and the wider set of included auth methods and admin features. If your app's shape is mostly B2B and your bottleneck is workspace structure rather than users, this is the better fit. Switch if you need unlimited orgs now and do not need Clerk's larger retained-user ceiling.

• Beats Clerk: Unlimited organizations and unlimited waitlist users, which is better for B2B tenancy
• Falls short: 10,000 MAUs, so it gives less free user headroom than Clerk
• Who should switch: Switch to PropelAuth if your product is B2B-first and organization scaling matters more than retaining more users per app.

Hexclave's free tier includes up to 10,000 auth users, 1 dashboard admin, 1,000 emails per month, email, OAuth, and magic links, plus community support. It is aimed at solo builders and side projects that want a simple auth and messaging setup without committing to paid infrastructure. It beats Clerk on simplicity if you only need one admin and a narrower feature set around email and login. It falls short sharply on user cap, team collaboration, impersonation, B2B add-ons, and the broader range of authentication methods Clerk includes for free. This is the option for builders who want a small, clean starting point and do not need Clerk's much larger retained-user limit. Switch if you are running a side project and want the lightest free setup possible.

• Beats Clerk: 1 dashboard admin with a small, simple free plan that covers email, OAuth, and magic links
• Falls short: Only 10,000 auth users and 1,000 emails per month, far less headroom than Clerk
• Who should switch: Switch to Hexclave if you are a solo builder or side project and want a minimal free auth stack.

Kinde's free tier includes 10,500 monthly active users, 5 monthly active organizations, unlimited dashboard seats, unlimited applications, 0.7% platform fee per customer transaction, custom billing plans, billing APIs, a self-serve portal, social sign-on, SAML and enterprise SSO, 2,000 M2M tokens, custom JWT claims, custom session duration, MFA options, self-serve import and export, and community support. It stands out because authentication, billing, and access management live together, which can reduce tool sprawl for SaaS teams. It beats Clerk on unlimited dashboard seats and on the amount of billing and subscription machinery included for free. It falls short on retained-user ceiling, user impersonation, and Clerk's broader free B2B and admin allowances. Switch if billing flows are part of the app from day one.

• Beats Clerk: Unlimited dashboard seats and free billing APIs with subscription-management features
• Falls short: Only 10,500 MAUs, plus less free room for impersonation and admin-style collaboration
• Who should switch: Switch to Kinde if you want auth and billing in one place and your team needs unlimited seats from day one.

MojoAuth's free tier includes 25,000 MAUs, email OTP, unlimited total users, Facebook and Google login, basic attack protection, hosted login and registration pages, and magic link authentication. It is a good fit for teams building passwordless or social-login-first experiences and wanting a hosted login surface with little setup overhead. It beats Clerk on unlimited total users and on having a very focused passwordless feature set that is easy to adopt. It falls short on retained-user capacity, dashboard seats, impersonation, custom domain support, and organization tooling. If your app only needs a lightweight login layer and you value passwordless flows above everything else, this can be the simplest switch. Switch if you want a straightforward login product and do not need Clerk's larger app and team limits.

• Beats Clerk: Unlimited total users with a focused passwordless and social-login stack
• Falls short: No free custom-domain claim here, fewer team/admin features, and less free retained-user capacity than Clerk
• Who should switch: Switch to MojoAuth if your main goal is passwordless login and you do not need deeper organization or admin features.
