6 free alternatives to Hexclave

Clerk's free tier gives you up to 50,000 monthly retained users per app, unlimited applications, up to 3 dashboard seats, and a broad auth feature set including prebuilt UI, custom domains, social connections, passwordless options, webhooks, account linking, and security controls. For teams, the free plan is also more collaborative than Hexclave because it includes multiple dashboard seats instead of one. It falls short on email volume because the free tier item list does not include an email sending quota like Hexclave's 1,000 emails per month. Switch if you want a more spacious auth platform for several projects or teammates.

• Beats Hexclave: 50,000 retained users per app and up to 3 dashboard seats
• Falls short: No free email-send quota is stated
• Who should switch: Choose Clerk if your main pain is Hexclave's 10,000-user and 1-admin cap, and you can live without a stated free email allowance.

Auth0's free tier supports up to 25,000 monthly active users, 1 custom domain, passwordless authentication, unlimited social connections subject to system limitations, 5 organizations, branding customization, basic attack protection, community support, 1 enterprise connection, self-service SSO, and SCIM. It beats Hexclave on user capacity and organization support, and it is a stronger fit if you need identity features beyond basic auth flows. It falls short on credit-card friction because custom domain use requires credit card verification, while Hexclave's free tier explicitly does not require a card. Switch if you need a bigger free MAU ceiling and more enterprise-shaped identity controls.

• Beats Hexclave: 25,000 monthly active users and 5 organizations
• Falls short: Credit card verification is required for the custom domain
• Who should switch: Choose Auth0 if you need more free MAU headroom and enterprise identity features, and card verification is acceptable.

SuperTokens includes email/password auth, social login and SSO providers, passwordless magic links, SMS and email OTP, username and phone-number sign-in, email verification, forgot-password flows, sign-up and sign-in UI, RBAC, a user management dashboard, session management, hooks and custom actions, SOC 2 compliance, and community support. It also stays free under 5,000 monthly active users on the cloud plan. Its edge over Hexclave is breadth of auth mechanics and account security. Its shortcoming is scale on the managed cloud side, since the free cloud allowance is 5,000 MAU versus Hexclave's 10,000 auth users. Switch if you want a deeper auth toolkit more than a larger free hosted user cap.

• Beats Hexclave: Broader auth feature set, including RBAC, session management, and passwordless flows
• Falls short: 5,000 monthly active users on the cloud plan
• Who should switch: Choose SuperTokens if richer authentication features matter more than Hexclave's larger hosted free-user limit.

Logto's free tier includes up to 50,000 monthly active users, 50,000 tokens per month, up to 3 total applications, 1 machine-to-machine app, 3 social connectors, 1 custom domain, 1 webhook, audit logs retained for 3 days, and 1 tenant member for console access. Compared with Hexclave, it gives you much more room on users and also adds token and webhook allowances that are useful for app and API integration. It falls short on included admins because the free plan only states 1 tenant member for console access, which is closer to Hexclave's single-admin limit than a collaboration upgrade. Switch if you are hitting Hexclave's user ceiling and need token-based auth infrastructure too.

• Beats Hexclave: 50,000 MAU and 50,000 tokens per month
• Falls short: Only 1 tenant member for console access
• Who should switch: Choose Logto if you need more user headroom and token quotas, but do not need broader free team access.

MojoAuth's free tier includes 25,000 MAUs, unlimited total users, email OTP, magic link, Facebook and Google login, basic attack protection, and hosted login and registration pages. It is a good fit for passwordless flows and social sign-in, and it beats Hexclave on raw user ceiling as well as on the explicit unlimited total users item. It falls short on team collaboration and admin depth because the free tier items do not mention dashboard admins or multi-admin access the way Hexclave does. Switch if your main goal is a higher free-user limit and ready-made passwordless auth pages.

• Beats Hexclave: 25,000 MAUs and unlimited total users
• Falls short: No dashboard admin allowance is stated
• Who should switch: Choose MojoAuth if you need more free users and passwordless-first login flows, not admin-heavy collaboration.

Kinde's free tier includes 10,500 monthly active users, 5 monthly active organizations, unlimited dashboard seats, unlimited applications, billing APIs, a customer self-serve portal, custom billing plans, and a wide set of identity and security features such as email and password auth, passwordless email, social sign-on, SAML and Enterprise SSO, MFA, custom roles, permissions, feature flags, and more. It beats Hexclave on collaboration because dashboard seats are unlimited, and it offers far broader platform surface if you also need billing and access management in one place. It falls short on the free user cap, which is only slightly above Hexclave's 10,000 auth users. Switch if your primary bottleneck is seats and you want a broader SaaS platform, not just auth.

• Beats Hexclave: Unlimited dashboard seats and integrated billing/access management
• Falls short: 10,500 monthly active users
• Who should switch: Choose Kinde if you need unlimited collaborator seats and billing features alongside identity.
