Clerk vs Hanko for Solo Developers

Quick Comparison

Clerk Overview

Clerk is the managed auth service that makes authentication feel effortless in React and Next.js applications. Drop in pre-built components for sign-in, sign-up, user profiles, and organization management. Configure social providers (Google, GitHub, Apple) through the dashboard. Protect routes with middleware. Done.

The developer experience sets Clerk apart. The useUser() hook gives you the authenticated user anywhere in your component tree. The <UserButton /> component handles profile management, session switching, and sign-out. The management dashboard shows user activity, sessions, and lets you perform admin actions.

Clerk supports email/password, social logins, multi-factor auth, magic links, and passkeys. It's a comprehensive auth solution that covers every common authentication method. The free tier includes 10,000 MAU with all features unlocked.

Hanko Overview

Hanko is an authentication solution built around passkeys and passwordless login. Instead of passwords being the default with passkeys as an option, Hanko flips the model: passkeys are the primary authentication method, with email one-time codes as the fallback. No passwords to store, hash, or breach.

Hanko provides web components (<hanko-auth> and <hanko-profile>) that you embed in your application. These aren't React-specific, they're standard web components that work in any framework: React, Vue, Svelte, Angular, vanilla JavaScript. The auth flow guides users through passkey registration and login, falling back to email codes when passkeys aren't available.

The self-hosted option is genuinely free. Hanko's backend is open source (written in Go), and you can deploy it alongside your application. The cloud-hosted version offers a free tier with 10,000 MAU, similar to Clerk. For solo developers who want passwordless auth without a managed service dependency, the self-hosted path is compelling.

Key Differences

Authentication philosophy. Clerk is a comprehensive auth platform that supports every method: passwords, social logins, MFA, magic links, and passkeys. Hanko is focused specifically on passkey-first, passwordless authentication. Clerk gives you everything. Hanko gives you the future of auth (passkeys) done really well.

Social logins. Clerk supports dozens of social providers out of the box: Google, GitHub, Apple, Discord, and many more. Configuring them takes clicks in the dashboard. Hanko's primary flow is passkeys + email codes. Social login support is more limited. If your users expect "Sign in with Google" or "Sign in with GitHub," Clerk is the straightforward choice.

Framework compatibility. Clerk's pre-built components are React-native and work best in the React/Next.js ecosystem. Other frameworks get less polished support. Hanko uses standard web components that work in any framework or even without a framework. For Vue, Svelte, or Angular developers, Hanko's approach is more universal.

Self-hosting option. Hanko can be self-hosted completely free. The Go backend is lightweight and easy to deploy. Clerk is cloud-only. There is no self-hosted Clerk option. If you need or want to self-host your auth infrastructure, Hanko provides that while Clerk does not.

User management. Clerk includes a comprehensive user management dashboard: view users, edit profiles, ban accounts, manage sessions, and impersonate users. Hanko's admin capabilities are more limited. The focus is on the authentication flow itself, not user management and administration.

Passwordless vs. traditional. Hanko's entire identity is passwordless. The UX is built around passkeys as the primary method, with email codes as fallback. There's no password field. Clerk supports passwordless methods (magic links, passkeys) but also supports traditional email/password. If you want to force a passwordless experience, Hanko is purpose-built for it.

Maturity and ecosystem. Clerk has been around longer, has more integrations, more documentation, and a larger community. Hanko is newer and more focused. Clerk's ecosystem advantage means more tutorials, more Stack Overflow answers, and more examples to learn from.

When to Choose Clerk

• You want comprehensive auth with social logins, passwords, and passkeys
• You're building with React or Next.js and want the best developer experience
• You need a user management dashboard for admin tasks
• You want a battle-tested solution with extensive documentation
• Your users expect traditional sign-in options (Google, email/password)

When to Choose Hanko

• You want to go passwordless-first with passkeys as the primary method
• You need a self-hosted auth solution that costs nothing to run
• You're building with a non-React framework (Vue, Svelte, Angular)
• You believe passkeys are the future and want to adopt them now
• You prefer open-source infrastructure you can inspect and modify

The Verdict

For most solo developers today, Clerk is the safer and more practical choice. It supports every auth method your users might expect, has excellent documentation, and integrates seamlessly with the React ecosystem. Passkeys are supported alongside traditional methods, so you get the benefits of modern auth without forcing users into an unfamiliar flow.

Hanko is the right choice for developers who are committed to a passwordless future. If your product targets tech-savvy users who have passkey-capable devices, or if you're building something where eliminating passwords is a feature (security-focused tools, for example), Hanko's passkey-first approach is elegant and forward-thinking.

The practical consideration is user expectations. Most users in 2025 still expect to see "Sign in with Google" or an email/password form. Passkey adoption is growing but isn't universal. Clerk lets you offer passkeys alongside traditional methods, easing the transition. Hanko pushes users toward passkeys more aggressively, which is great for security but might confuse users who haven't encountered passkeys before.

If you're unsure, go with Clerk. You can always enable passkeys as an option and see how your users respond. Going all-in on passkeys with Hanko is a bet on the future. It's probably the right bet, but it's still a bet.
